hankg Posted March 21, 2007 Author Share #101 Posted March 21, 2007 Advertisement (gone after registration) BTW the 90mm macro-elmar f4 mounts directly on the viso III and gives 2 close-up ranges depending on whether it's collapsed or extended. [ATTACH]30357[/ATTACH] What is the approximate range with the 90 collapsed on the Viso? Normally the range for regular lenses mounted on the Viso is very restricted. I had'nt thought about using a collapsible lens collapsed. Are all the optics in the head of the lens? Link to post Share on other sites More sharing options...
Advertisement Posted March 21, 2007 Posted March 21, 2007 Hi hankg, Take a look here Visoflex + 65mm + M8. I'm sure you'll find what you were looking for!
Guest guy_mancuso Posted March 21, 2007 Share #102 Posted March 21, 2007 I got my 5x Vertical finder yesterday which was realy nice and clean from Tamarkin but now i am on to some lenses outside the 90 mm apo and 75 lux . They really offer you very little in distance like 5 inches or so. Been thinking about the 90 macro or something that I can focus about 18 inches away when needed. I would like something that i can shoot the size of a pack of cigerattes for (scale only here) and than something like a a quarter coin. I see many 90mm on e-bay and having trouble with which one to get ,I see some collapsable ones and than all kinds of designations. The 90 macro withour 30 percent is 1135.00 which is a nice price. Just wondering with and without the Visoflex how much range you can get with it. Link to post Share on other sites More sharing options...
hankg Posted March 21, 2007 Author Share #103 Posted March 21, 2007 The new 90 sounds nice because if it has a decent range on the Viso collapsed, it can also do double duty as a compact walking around lens which is good in the near range. However I recently purchased one which back focused badly. I sent it to DAG along with some other lenses to be calibrated and he said the lens was mechanically on but something about the optical design prevented him from being able to calibrate the focus. That didn't inspire any confidence in the lens for me so I sent it back. Maybe I'll reconsider and try and get an up to spec copy. I'll let you test it first Guy:) Link to post Share on other sites More sharing options...
Guest guy_mancuso Posted March 21, 2007 Share #104 Posted March 21, 2007 Thanks Hank it seems like a very intriquing lens because we can get double duty with it with the Viso and without. Really like the Viso and it is in my big bag to go on all jobs. Just never know if you want to get close to something. It also solves the not having a DSLR with you issue. I shot this for a client yesterday one of the many variations but I used the 75 lux becuase it is the closet focusing lens i have , now the 90 macro would have been a good choice and if i need to drop in closer on the buttons than it would have been easier. The Visoflex with the 75mm gets about 2 buttons in size but I have nothing in between and that is the area that is my concern is that cigarettes box size. Welcome, dear visitor!

wparsonsgisnet Posted March 21, 2007 Share #105 Posted March 21, 2007 Guy, are you using an adapter with the 75 'lux on the viso? If so, which one? The viso chart doesn't include modern lenses, of course. I note, in the picutre above, that you have chosen a particularly interesting angle for the object, to give it energy. Therefore, I wonder about the f-stop. You must have been closed down *a lot* to get this much DOF. When I have captured all your hints and prescriptions in one place, I'll publish them and say I'm you. BTW -- nice pic. I like your idea of carrying the viso in your (big) bag. Having seen (1) all your lighting setups, (2) the (long) list of your lenses, and (3) the size of your car, I'd like to see a pic of the two sherpas who load your car each day.

Guest guy_mancuso Posted March 21, 2007 Share #106 Posted March 21, 2007 I shot this without the Viso just a straight 75 lux at about f 13. The Viso will take the regular M mounted lenses without any adapters. Bill since buying the M8 i really have cut my load down a lot . I have a commercial shoot today but i am down to three bags a roller bag for the stands tripods and such and my lighting I am using the Twinkles from Dynalite there 400 watt mono lights that are very small but I can get four of them into a Lowe Pro roller 2 which is not really a big bag , the 3 roller was much bigger and that is gone now . The twinkles are nice and will get the job done but there not fashion strobes and there durability is not like Profoto's but for me they will work good . i have 4 now but will get 2 more . I have found i just don't need big power packs shooting digital 35mm and with Leica glass half the time i want F4 anyway, I am constantly dialing lights back because of too much power. That is pretty rare to hear most times we can't get enough juice. So my load has come down and at my age it is a welcome. So i am down to about 140 lbs of gear and i decided if I need big power than just rent it and charge the client. There are 2 rental houses in Phoenix wher I can get all the Profoto's I need almost at any time. Rather put my money into the camera gear and lens choices and i may add to the M8 a MF system but that has not been decided. Problem is i have no customers saying my DMR and M8 files are not big enough or good enough so hard to justify MF when no one is complaining and they keep calling me back.

wparsonsgisnet Posted March 21, 2007 Share #107 Posted March 21, 2007 Advertisement (gone after registration) Guy, if the file isn't big enough for them, just upsize it in PS with bicubic smoother to about 500%. You get a several-hundred MB file. That ought to satisfy them. As it happens, I am in the process of comparing different upsizing tools (soon as taxes are done). But, a 500% upsize in PS looks *just* like the original on my screen. Honestly, I can't image that a client wouldn't be satisfied with the dng from one of the digiLeica's. When digital was just beginning, I noticed that most mags were regularly using images that were clearly from 35mm cameras. And, the early digital pix were clearly full of artifacts. The digi-images from Leica glass are in a different league! Link to post Share on other sites More sharing options...
Guest guy_mancuso Posted March 21, 2007 Share #108 Posted March 21, 2007 Most uses the M8 and DMR files are just perfect and don't really not much more. there are times though the detail from the MF systems would be a benefit. Also there is a great program from Alien Skin called blowup that is very good if you have that need to go big. But using leica glass with it's micro detail is a huge benefit Link to post Share on other sites More sharing options...
wparsonsgisnet Posted March 21, 2007 Share #109 Posted March 21, 2007 Guy, I have A.S. Blowup and G. Fractals. They are the sw I'll be using to compare with PS's upsize. Watch this space. Link to post Share on other sites More sharing options...
Guest guy_mancuso Posted March 21, 2007 Share #110 Posted March 21, 2007 Bill would love to see a test like this with Blwup , GF and PS Link to post Share on other sites More sharing options...
wparsonsgisnet Posted March 21, 2007 Share #111 Posted March 21, 2007 It's coming; I promise. Almost done with the tax stuff. My expectation is that we will all agree that there is no substantial difference. After all, I don't see anyone complaining about upsizing, whatever their method. How many mathematicians can dance on the head of a pixel? At least I'll have several hundred dollars of software to show for my efforts. Link to post Share on other sites More sharing options...
hankg Posted March 21, 2007 Author Share #112 Posted March 21, 2007 Bill, I am using Pro Photo Zoom 2 (S-SPline) and I like it a lot. I've also got AS which I use for other things (I find it's nice to add a bit of fine grain with AS to an M8 image enlarged more then 150%). Download the demo or send me your test file and you can add that to the enlargement test. When you are ready let's start another thread on enlargement. The high end stock houses insist on 12+ MP uninterpolated for capture which leaves the M8 out. In a blind test I'm sure the M8 (enlarged with Pro Photo to 12MP) would match or best any 12 mp camera available even at 1:1 on screen. On most 3D subjects (I'm excluding resolution target tests here) it would be on the same level as the 16MP Canon. This is the only reason I wish Leica had stuffed a few more MP's in the chip.

wparsonsgisnet Posted March 21, 2007 Share #113 Posted March 21, 2007 Hank, thanks for the offer of collaboration. I'll be in touch shortly, if you promise not to make my image look better than I can. Question: does the MP rating of the chip relate in any way to the number of individual sensors in the chip?

hankg Posted March 21, 2007 Author Share #114 Posted March 21, 2007 Question: does the MP rating of the chip relate in any way to the number of individual sensors in the chip? Yes, number of sensors capturing R G B determines the chips resolution. Link to post Share on other sites More sharing options...
Michael M. Posted March 21, 2007 Share #115 Posted March 21, 2007 Guy, are you using an adapter with the 75 'lux on the viso? If so, which one? The viso chart doesn't include modern lenses, of course. There is (was ) an adapter in catalogue (Leitz Wetzlar Germany) available to fix actual M-mount lenses to bellows II Ordering number: 16596 G (on bellows side E65x1 and to front side there is M-bajonet) But be careful by using actual M-lenses for macro in "normal" position (frontlens to object) expecting still highest performance level when comming down to ratio 1:5. You will loose performance of lense (resolution). Even the new "Macro-90mm" will be suggested for macro by Leica "only" down to 1:3 only. When forcing the Viso to 1:1 and above it is necessary to invert lenses for better performing in resolution. This could be done by related stepup-ring connecting lens filter side to bellows II E65x1 (or using special designed optics - Photar) Still the "old" 3,5/65 Elmar will come up in this constellation to a very powerful combi (Viso and bellow II and inverted Elmar for ratio 1:1 and above) as it ist very easy to be handled with adapter stepping ring 46 to 44 x0,75 plus 16598J adaptor. Optically it will perform better (inverted mount) in the range above 1:1 compared to every actual M-lens in standard mount. And additional benefit of the old Elmar is that it's designed very slim at backside (now looking to object), so illumination get's much easier when distance become some cm and focus distance to object is also little better this way round...

Woody Campbell Posted March 21, 2007 Share #116 Posted March 21, 2007 I took 4 images earlier today to answer a few of the above questions: 90mm macro f4 at close focus without "eyeglasses"; same lens at close focus with eyeglasses; same lens at far focus collapsed on the viso III; and same lens at close focus extended on the viso. All exposures at f5.6 and iso 2500. Without eyeglasses, closest focus Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members! With eyeglasses, closest focus: On viso collapsed, farthest focus On viso extended, closest focus You will see that the third image (viso collapsed) covers a larger area than the second, so this combination gives you continuous coverage from infinity to the scale of the fourth image.

Guest guy_mancuso Posted March 21, 2007 Share #119 Posted March 21, 2007 Woody this is perfect just please clarify one thing for me when you say eye glasses you are talking the macro adapter that cost 700 hundred or so. So if I see your chart correctly than the first image is the macro alone and the 3 and 4 are with the Viso and that is perfect for me or is the fourth with something else Link to post Share on other sites More sharing options...
Woody Campbell Posted March 22, 2007 Share #120 Posted March 22, 2007 Woody this is perfect just please clarify one thing for me when you say eye glasses you are talking the macro adapter that cost 700 hundred or so. So if I see your chart correctly than the first image is the macro alone and the 3 and 4 are with the Viso and that is perfect for me or is the fourth with something else Guy - The first image is close focus for the macro-elmar without macro adapter (about 80 cm); the second is close focus with the macro-adapter (about 50cm or 20 inches or so); the third is the m-e on the viso III collapsed at far focus (which I would say is 55cm (22 inches) or so, but clearly further away than near focus in the second image); the fourth is close focus on the viso with the lens extended. This means that the entire range from infinity to the fourth image is continuously covered. Here's a link to Irwin P's review of the m-e, which is why I bought it - I got the macro-adapter as an afterthought. You will see that he compares it favorably to the 90 chron. http://www.imx.nl/photosite/leica/mseries/testm/MEM90/MacroElmar.html This lens has very good flair resistance. I keep a 486 filter on it as there is very little downside on a long lens. I haven't had any focus issues, but the 1.25 magnifier is essential. Drop dead perfect focus is very difficult to acheive wide open with the macro adapter. It doesn't lock in its collapsed state so you have to watch that it doesn't slide out as you are working on the viso, but of course if it did it would be obvious through the viso. In a pinch at f4 it could be used for portraits, but of course at f4 extreme selective focus effects aren't possible. Brokeh is creamy and attractive. Overall it has a very similar look to the 75 chron (which I own). I bought it because I don't need speed in a long lens and it is very compact. I found a metal 12575N shade on e-bay, which inverts over the collapsed lens for storage, and a 14033 cap to go over that. The 20 Euro note in the picture is significant - it represents my cash net worth after buying all of this stuff. Link to post Share on other sites More sharing options...
