  1. Agreed but I feel like the limiting factor in digital photography these days is not pixels or iso, it is dynamic range. That’s still one where big wells matter. The other one is sensor read out speed which affects AF, the refresh rate of an EVF, as well as video performance. I think that this is one place Sony (and maybe Nikon and Canon - I don’t know) did it right with the 7, the 7R, 7S for different types of shooters.
  2. I agree that they are different. I like the SL for astrophotography, telephoto, and video. I think that if I had a really wide angle lens it would be the one for that too. For the small amount of architecture that I do for my friend the CV 15mm is good enough. I kind of wish there was a macro though. For some things I can use the 90-280mm at near minimum focal distances in a macro-ish sort of way. (At the moment for real macro I use the Olympus TG-5 whose minimum focal distance seems to be the surface of the glass.) This is the capability camera, It can do basically anything a pro needs to do. The M240 is my favorite camera. Maybe the M10 is in my future sometime in the future For capability and portability I find the Summilux 50mm the perfect match. With one body and that one lens I can do so much. Sometimes my like backpacking my 28mm Summicron works better. The compact ultraportablity and inoffensiveness just works. Together they are great complements to each other.
  3. I like the look of the Gitzo GH1382TQD Series 1 Traveler Center Ball Head mentioned above. Back when I bought my Gitzo tripod they were using those larger quick release plate and I didn’t like them because they didn’t fit my Leica M or my previous mirrorless systems. I have the top of https://www.bhphotovideo.com/c/product/1277304-REG/3_legged_thing_ahsw_equinox_airhed_switch.html on a Leica ball head. It works well but if I were doing it again I’d use either the Gizo above or the full AirHed Equinox.
  4. I for one wish there were one. I also wish there were focus bracketing when there is one because I can’t slew through the focal range as fast or accurately as the camera can. In the meanwhile there is the TL 60mm which may actually be advantageous due to the slightly larger DOF. The obvious cost is resolution.

  6. For this trip I'm taking an Olympus TG-5 with an Ikelite housing, and a GoPro Hero 6 with a SuperSuit. If I get notably more into underwater photography, I will look into one of those other two options along with the 16-35mm. I couldn't budget in all the additional gear for the SL for this trip. Plus with both of these, as you suggested I'll be making cheap mistakes. I also looked for something like the SuperSuit for the Leica X-U couldn't find one. To me that seems like a nice combination. However since this is a question that may be answered by only a very few people in the world, I thought I would ask expecting it to linger for a while before I got an answer. I do think that the SL is potentially a good camera for underwater use. Its few buttons and simple interface should make designing a waterproof housing easier. My TG-5 has 9 buttons on the back, 2 on the top including the shutter, two wheels to turn and a zoom lever. The SL on the other hand has 3 on the top, 5 on the back, two wheels, the on/off switch and joystick. So fewer case penetrations than even a compact camera.
  7. I've heard that Subal has a dive housing for the Leica SL. http://www.subal.com/a445c98c2c1/Housing/UW_Housings/Sony_Leica/SL.aspx I also found that BS Kinetics can make one. https://bskinetics.com/?lang=en Has anyone tried either of these?
  8. I got a really nice shot of the moon last night with the 90-280 but I had to crop in a huge amount leaving me with only a 526x526 px image. Never the less it is lovely. This really does leave me wishing for something longer. I've also been doing a lot of birds lately and though the 280mm is good for the large well habituated shorebirds and water fowl that live next to the mult-use trail near my house, i still have to crop in a lot. Away from where I live birds are much harder to shoot with only a 280mm I guess that I could attach the SL up to an actual telescope or a spotting scope. Or I could get a vintage Telyt R lens. The Leica R-L adapter costs as much as the lens but I guess that I could get a cheaper Kipon. The point is there are still a couple gaps in the SL lens lineup. Macro Very long telephoto Some wide AF lenses. A wide TS (Tilt Shift) lens for architecture. None of these are impossible to work around and these special purpose lenses probably won't ever have the volume of general purpose lenses like a fast 50 or a standard zoom or telephoto.
  9. Yeah exactly what I’ve been hoping for but I have been thinking about the 60mm TL lens the downside is only 12MP to show detail but at the same time much lighter to hold. I would also appreciate focus stacking or at least bracketing built into the camera.
  10. While my M has been away in the shop, I've been getting to know my SL a lot better. Both hardware wise and software wise, it seems like a great camera. This seems like it is going to be a plenty good enough camera for me and what I do for a long time. Never the less, I started keeping notes about what I would like in the next generation hardware. Mostly it involves the IO ports: Make both card slots UHS-II 3x USB-C type 3.1 ports rather than the accessory port, the HDMI port and and the Micro-B port. The remote can be a USB HID device. (just like a mouse and a keyboard, an external numeric keypad. Those are all HID devices) The audio adapter can a USB sound card sort of like https://www.amazon.com/Adapter-BENGOO-External-Converter-Headset/dp/B072BMG9TB/ref=zg_bs_3015427011_2?_encoding=UTF8&psc=1&refRID=SBDW56WFB4YNH8N7FMFK I think that this is basically what the audio adapter is already but it has a funny connector on it. This could easily be used for stereo or multi-channel input for advanced users. You are not limited to a TRR or a TRRS there are already USB devices with multiple XLR inputs if that is what you need. USB-C has a DisplayPort alternative mode. So that if you want to send video to an external recorder you can. If recorders have USB-C use that. If it only has HDMI, then the user can take a standard USB-C->HDMI adapter, the kind you use on your MBP to convert to HDMI then use a standard HDMI cable or get one of those cables USB-C with the HDMI adapter built in. For tethering the camera itself becomes USB-C hub with multiple devices, a camera - just like a webcam but better, a HID device for all its buttons, and mass storage for its cards. Imagine using your Leica SL as your webcam for skype? USB-C also can also do Power Delivery - charge the battery in the camera. You wouldn't always need to bring your battery charger or if you lost it, then you could use the camera body to charge the camera. USB-C PD could also be used to run the camera for those very long video segments that last longer than a battery. You wouldn't need some kind of dummy battery to provide power to the camera. The external charger should also take USB-C that way you don't have to worry about plugs. 15W is plenty and you could plug it into any handy cell phone charger. With USB-C Power pass through plug your MacBook USB-C charger into the camera as well as the external charger and it will charge both batteries at once. With all the ports the same, you are better able to do cable routing. USB-C ports are well engineered and rugged - probably more so than any of the connectors built into the current SL. If one fails in the field, you just use the others. USB-C ports are more compact allowing a smaller area for ports. Video recorders are relatively expensive. Imagine if you could plug in a suitably fast USB-C hard disk or SSD and the SL would just write to it. This is where you would probably need to plug in something like your MBP USB-C power brick into another port of the camera to provide power to the camera and the external HD. Plug a USB-C to lightning cable into the camera and then use your iPhone, iPad as the external monitor. Plug a USB-C monitor into the camera for a really big display, also the monitor could power the camera. All of these are just different modes for USB-C and well within the capabilities of the current chips that are available. The trick would be changing the mode of the ports from host mode to device mode as needed. Thoughts?
  11. Does anybody know? Is the Audio Adaptor AA-SLC4 mono or stereo?
  12. I frequently travel with just my 50mm Summliux and my m240. So it sounds sensible to me. Some outdoor places with big vistas and some small indoors I find that 50mm is to tight and go with my 28mm Summicron instead. I don’t know Japan. Maybe a 35mm Summliux would split the difference but I don’t have one. There are others that seem to agree. https://youtu.be/VBY7K4TmZ0c
  13. Kind of have been thinking about this all night. I have a Nature Conservancy calendar in my kitchen. The "free" one they send you when asking for additional contributions and what they have is what I would call "animal portraits" the kind that really do need a HUGE telephoto lens. There is another approach to wildlife photography where it shows the animals in the context of their environment. So: For humans portraits 85-90 or 105mm but in context i.e. street photography 28-35 or 50mm For wildlife portraits 400-560mm or more but for wildlife in context ??
  14. Good advice. Thank you. The one disagreement that I have is that the 90-280 behaves like a 135-420 on a TL system. That may be long enough for most wildlife photography.
  15. Something that it seems has not been said is that there seems to be a bit of a personality difference between MF and 35mm format shooters. MF shooters seem to be more inclined to carefully setup a shot, control the lighting, work on it heavily in photoshop and make one picture. 35mm shooters Tend to be a bit more shooters and more often mobile. They produce more shots and seem to work on them less. I think broadly speaking, this inclination is reflected in the kind of work produced. A certain kind of photographer is drawn to a particular kind of equipment that inclines one to a general workflow which ultimately produces work that is subtlety different. So broadly speaking there is a 35mm look and a MF look but it’s only partly a result of the equipment.
  16. What's people's advice on how to sell lenses: I just got a SL and though the TL lenses are adaptable to the SL they really aren't ideal. For example the 55-135 does zoom to the FOV of a 200mm but then it only uses 12MP and so cropping in really doesn't work. What I want to get is one of those 90-280mm. I live right next to an estuary and I kind of want to do birds and wildlife from time to time. My other system is an M and for normal FD's it is great, I basically got the SL to do things the M doesn't do well like tele, ultra wide and macro. What's your best advice: 1) sell here - small focused market (hassle of shipping) 2) sell ebay- larger market (hassle of posting and shipping) 3) trade in at local leica store - maybe they will give me a better trade in value. What I'm thinking of selling are: APO-Vario-Elmar-T 55-135mm Boxed lke new Super-Vario-Elmar-T 11-23mm Boxed lke new Summicron-T 23mm Boxed excellent to good - some external paint has rubbed off) Also should I sell now or wait for when the new rumored TL with the EVF comes out the one with the code name Clooney?
  17. Anyone figured this out yet? When typing a WiFi password where is the parenthesis? At first I thought that it was a font problem and the rendering of () on the keyboard page next to the + just looked practically indistinguishable from [] on the page next to the back-tick ` but one of my common haunts has a parenthesis in its WiFi password and it won’t connect to that WiFi network.
  18. The three big downsides that I have with the current state of using the iPad Pro for the worflow are: 1) The speed and capacity problems associated with the import. I have a iPad Pro 256Gb but I have quite a few things on it. While importing a couple hundred photos is almost reasonable in that it takes a about 15min. I could only do this a few days on location when I’m heavily shooting before I would run into capacity. A) the import actually takes a considerable amount of power. I imported 250 photos from my M240 last weekend and if I recall correctly it knocked the iPad battery down by about 30% by the time I got the photos into Lightroom. It is a multi step process. You have to import into photos and then import into Lightroom. C) It kind of annoys me the way that this pollutes my Photo stream. I usually import into LR and then export finished products into my Photos stream, this kind of breaks that system. My problem. 2) No backup. Yeah I leave the imported pictures on the card and there is the cloud but it isn’t the normal backup to a 3rd hard drive and normal Mac backup. A) the cloud backup built into Lightroom mobile takes a non-trivial amount of time — like hours on WiFi to get the photos over to the desktop Lightroom. And during this time the iPad must be on and running Lightroom. These two things make it so that it only seems practical while in a hotel or restaurant with WiFi and with access to power. 3) No tagging other than picks and stars. This would be the ideal use for Lightroom Mobile. 4) Editing in LR M is not quite as refined or as feature rich as in the Mac version A few other things that are kind of problematic: 1) The lack of presets especially import presets. 2) There is no really easy way to sync changes across multiple shots. 3) There is no way to make a virtual copy to make a different version of a particular shot. The things that I do like about Lightroom Mobile and the overall workflow: 1) So long as you have a decent network, flipping through the images for the first time and pulling out the Picks and Rejects are really great. I think it is better than on the desktop. A) my only complaint is that it does take a second or two to load the images and sometimes waiting for the image to resolve to the high res version from the low res JPG import impacts my initial emotional response to the image. I don’t know how many times I’ve done, “out of focus - reject next” only to realize a second later that the photo is fine it just hadn’t loaded completely yet. 2) Being able to carry that tiny amount of gear and use so little power. Even though I complained about how much power it sucks when importing. In comparison to what my Mac uses it is really small when you’re working off of solar power and portable battery packs, this wins. 3) It really is quick and responsive. A) as long as the photos have loaded already or you have a fast network
  19. With M lenses I just read it off of the lens. With TL lenses in MF mode you hit the info button a few times until it comes up while turning the focus ring and the Focus scale will appear on the bottom of the screen. One proble that I have with the T/TL UI is that info cycles through histogram, focus scale, and nothing. I think those should be toggles so that we can choose to have focus scale and histogram and data fields all at once if we want....but this is the SL list not the T/TL list. (Haven't seen the TL2 yet)
  20. I don't own a Leica SL (yet) but I have the original T and a M240. I stopped by the Leica Store in SF to play with one for a bit to see what I felt with one in my hand. One thing that I could have sworn that I'd seen somewhere is the OLED display on top having the DOF scale in it. When I was in the shop I couldn't figure out how to make it do that. The guy in the shop swore he never saw that and we both went through the manual quickly and couldn't figure out how to have it there. One thing that is nice with M lenses is that I can look down from the top of the camera and see what range is going to be in focus given the selected aperture. With the T when I need to and I'm in MF mode, I can hit the Info button on the screen and bring up a focus scale. How do you bring something like the focus scale that the T has up on the SL? Is there any way to have it appear on in the little OLED display so that I can look down on the camera and see it? If not, you do you scale focus? There are at least a couple of situations that I know of when I want to do that. One is astrophotography. With M lenses I can basically rack the focus up against the mechanical stop and that is infinity. With the TL lenses, at least my 55-135mm seems to focus beyond infinity and so I can't just overspin it to the right, I actually have to pick some fine detail on the horizon and then focus on that. How do you do that with the SL and the SL lenses.
  21. My professional job is doing high performance computing. I'm well aware of Dennard scaling (god am I aware of that). We can get down and dirty on this if you want but since this is camera forum it didn't seem like the place for that. ;-) Never the less the number of pico-joules per a fixed amount of computation has continued to go down over the years. You can see that in the reciprocal of the performance/Watt charts on: https://en.wikipedia.org/wiki/Performance_per_watt With higher resolution charts you can see that the each process technology somehow manages to squeeze a bit more computation out of each Joule used. It isn't the wonderful halcyon days before the end of Dennard scaling. Never the less Koomey's law https://en.wikipedia.org/wiki/Koomey%27s_law still is managing to hold for the time being and process technology is part of that. That being said, I have no idea if the TL2's embedded processor moved to the next semiconductor process. I can however, tell from the specs that it will need to write more data to the SD card (actually a fairly expensive operation with regards to energy consumed) and it will have to read more data from the sensor and process it. I also think that increasing the number of AF focus points is likely to increase the processor's workload and so I think that the 1.5 increase in the resolution and the 1.6x decrease in CIPA score is more than coincidental. It is normal problem scaling physics. Try getting an exaflop machine to only consume 20MW. That's where you need to pull a few rabbits out of your hat. ;-) It is the same problem just in a different form.
  22. In computing in general: - the faster you run a processor the more power it consumes - if you want something more responsive you generally need to run faster; - the more bits you have to move the more power you consume - going from 16mp to 24mp means that you will need to move more bits; - the more processing you do the more power you consume - adding more focus points over which you do contrast maximization to find focus lock - the more blocks of storage that you write, the more power you consume - writing to SD consumes energy based upon the number of blocks you write so if you are writing a 24mp file rather than a 16mp file you will need to consume more energy. If you just take the number of MP 24/16 is 1.5 which is darn close to 1.6x in the CIPA score and so I'd guess that most of that is due to the bump up of MP in the sensor. However, as new semiconductor process technologies iterate you also get a reduction in power consumption for each and everything operation that you do. So they probably iterated the electronics one generation forward and got some benefits from that which were partially cancelled out by the MP bump in the sensor.
  23. I was kind of curious about that myself. I ran the numbers a while back: 55-135mm @135mm Horizontal: 10.0° Vertical: 6.61° Diagonal: 12.0° 90-280mm @280mm Horizontal: 4.84° Vertical: 2.19° Diagonal: 5.79° So it is like a 8.4x zoom which should be enough for some birding. The T is optimized as a general use camera. It isn't really targeted at the kind of photographers that need super telephotos. That is more where the more pro oriented SL would fit for sports and wildlife but currently Leica hasn't put a SL supertelephoto on their roadmap yet. Maybe in 2018? But that is a topic for the SL forum not the TL forum.
  24. A couple things that I noticed: The USB-C port only charges the battery at 1A or 5W. USB-C can do much better than that 2A is in the spec. However, charging the battery may not need that much. The original T charger is 8.4v @ 0.65A which ends up being only 5.46W. So the battery may charge in the T almost as fast as in the external charger. They included a micro HDMI port which I think is odd because they could have run DisplayPort and HDMI over the USB-C. I don't know if anybody has tried this but it could be possible. You might be able to plug your TL2 into a new USB-C 4K monitor and it will charge and display images there. The removal of the flash should help with weather and dust sealing. I think a couple of nice accessories that Leica should make for the T, TL, TL2, and M10 are: - A GPS without the EVF that fits in the hot shoe and just geotags your pictures. - A little shim that you put in the hot shoe between the camera and the EVF which has a port for a flash trigger while accepting the EVF and providing the power and digital signals needed to run the EVF. That way you can use an off camera flash and the EVF at the same time. It looks like a good step forward for the original T concept. Like others, I think that I would like Leica to expand the range of body styles for the TL lenses. 1) A TL2 like camera with a built in EVF and GPS - maybe this is the slightly taller 5370? 2) A camera with an X like body and controls. It could be basically the same camera guts but with a smaller non-touch display a few more buttons and a different UI part of the firmware. 3) Alternatively a mini-SL UI. I have mixed feelings about this. I don't like the viewfinder in the center but I do think that the SL's UI is well designed and probably a better fit than trying to adapt the X or M's UI to the TL for people want a more traditional body style and controls.
  25. I wish Leica would make all their cameras and chargers charge off of USB PD over a USB-C connector. Surely profile 2 12v @ 1.5A is plenty to charge a camera's battery. Then we can forget about all these AC plug types and wall warts and you can use the same charger as you do for your cell phone and (new) laptop.
