jonoslack Posted November 9, 2015 Share #61 Posted November 9, 2015 Advertisement (gone after registration) anyone have an idea how other rangefinder lenses (voigtlander, zeiss) will work on SL? I have a pretty good idea - although I haven't tried any. Which is that they'll work noticeably better than they do on a Sony A7 and slightly worse than they do on an M240 Helpful to choose the best coding match (just like the M240) all the best Link to post Share on other sites More sharing options...
Advertisement Posted November 9, 2015 Posted November 9, 2015 Hi jonoslack, Take a look here Leica R and M lenses on the Leica SL (Typ 601). I'm sure you'll find what you were looking for!
wildlightphoto Posted November 9, 2015 Share #62 Posted November 9, 2015 Does the 24-90mm zoom stop down? Or do you focus that at working apertures? Since the SL camera body has a DOF preview button I expect the 24-90 zoom has an automatic diaphragm. Link to post Share on other sites More sharing options...
Leicaiste Posted November 9, 2015 Author Share #63 Posted November 9, 2015 Since the SL camera body has a DOF preview button I expect the 24-90 zoom has an automatic diaphragm. The SL has non DOF preview button as far as I know. The DOF limits can be read on the top screen. Link to post Share on other sites More sharing options...

Guest JMF Posted November 9, 2015 Share #65 Posted November 9, 2015 Hi There No problem If you have a TL to M adapter (which you'll need anyway) then you can get an M to Nikon adapter . . . and code it the same as the image Wilson has given - it will then bring up the R lens list correctly (I've done this on a Contax to M adapter successfully). Thx Jonathan, will try it first on the M240 ! Link to post Share on other sites More sharing options...
wildlightphoto Posted November 9, 2015 Share #66 Posted November 9, 2015 The SL has non DOF preview button as far as I know. The DOF limits can be read on the top screen. According to Jono's field report the button on the front below the red dot defaults to DOF preview with AF lenses. Link to post Share on other sites More sharing options...
ramarren Posted November 9, 2015 Share #67 Posted November 9, 2015 Advertisement (gone after registration) Since the SL camera body has a DOF preview button I expect the 24-90 zoom has an automatic diaphragm. The SL doesn't have anything that says "DoF Preview". The option they have is Exposure Simulation/Depth of Field Control ... It is a three-position option that, with dedicated lenses, allows you to see normal recording view (where the actual disposition of the aperture state is up to the camera and possibly also dependent upon the currently selected exposure mode), "effect of the aperture" view (where you force the camera to hold the aperture at the taking setting for DoF evaluation), and "effect of the aperture and shutter speed" view (where you see both the taking aperture effect and the effect of the taking shutter speed so you can assess motion blurring, etc.). Yes, these options are mapped to the FN button for direct activation by default. I'm not sure they can be mapped to another button, although that might also be possible.

wildlightphoto Posted November 9, 2015 Share #68 Posted November 9, 2015 ... "effect of the aperture" view (where you force the camera to hold the aperture at the taking setting for DoF evaluation)... This function is a DOF preview, no? Link to post Share on other sites More sharing options...
Leicaiste Posted November 9, 2015 Author Share #69 Posted November 9, 2015 This function is a DOF preview, no? Yes, you are right. As you said earlier it could mean that the SL used with SL lenses works with an automatic aperture system. Link to post Share on other sites More sharing options...
ramarren Posted November 9, 2015 Share #70 Posted November 9, 2015 This function is a DOF preview, no? It is, but the point was that when in "normal" viewing mode, it is up to the camera to decide what to do with the aperture. Just like with the Olympus E-M1, I can hear the aperture blades on certain lenses changing position during normal view as light levels in the viewfinder change, but when I put the camera in Preview mode, they are constrained to taking aperture. The same thing happens with the E-M1 whether I use its native mFT mount lenses or my adapted FT mount lenses from the SLRs, where the SLRs operate like any traditional SLR with respect to aperture control and auto-diaphragm. These electronic TTL cameras operate differently from SLRs, that's all, because they have different viewfinder mechanisms with different capabilities.

Guest JMF Posted November 9, 2015 Share #71 Posted November 9, 2015 Thx Jonathan, will try it first on the M240 ! Just did mark the 6 bit code on a Novoflex adapter with the help of the Match Technical coding guide I have from the M8 days and it works, great ! Thx a lot Wilson, Jonathan and LUF !

jonoslack Posted November 9, 2015 Share #72 Posted November 9, 2015 do i have to actually "code"(sharpie,...) the lenses or can i just manually select a match? if i select manually i will have to do that every time i put the lens on, correct? i ordered the SL but still have a couple of voigltander lens left over from my M8 days, they are obviously not coded... You can manually select them If the SL doesn't detect a lens code then it will give you a list of M lenses when you press the Lens Profile option. So - no coding needed - I think it remembers the last lens you used . . Link to post Share on other sites More sharing options...

This is what I use the User Presets for on the M-P. I have all four set up identically except with respect to lens codes ... one for my M-Rokkor 90, one for my Summilux 35 v2, and one for my Nokton 50mm f/1.5 ASPH. The other one is set to Automatic so I use that for all coded lenses (24 and 75 at present, I'll have the 35 coded soon and maybe next year will replace the Nokton with a 'Cron or 'Lux 50). I plan to set up the SL user presets similarly for my most used R lenses, presuming it is possible to do so. The R lenses on the SL impose another level of complication until the dedicated R Adapter SL becomes available. Link to post Share on other sites More sharing options...

Hmm, well, although it'd be nice if the dedicated R to SL adapter read ROM chips I don't think it's a given . . . and if it isn't, then it'll just be a one piece version of the current (extremely servicable and uncomplicated) stacked T to M and M to R adapters.

The R lens scenario is quite a bit more complicated than that. There are 1-cam, 2-cam, 3-cam, R-Only, and ROM lenses in the R line ... The dedicated R Adapter SL can possibly do four things that would make it significantly more than the stacked adapters: AASD, which we've talked about ad nauseam. Read the ROM on lenses so equipped. (I know I can have my one cam and two cam lenses updated to three cam. I think there might also be the service to updated my 3 cam lenses to ROM only, but that would be expensive and it would kill them for use on the Leicaflex SL.) Translate the mechanically indicated aperture setting on the lens into an electrical value and transmit that to the body. Allow body control of the aperture (the way some R bodies including the R8/R9 do) to allow Program and Time mode exposure operation. This works with R-Only, ROM, and 3cam lenses. I'll be surprised if they produce what is exactly the same thing as the stacked adapters ... that wouldn't make sense. A dedicated adapter should at least do the ROM data transfer and, hopefully, the rest of it. If it is constrained to allowing only R-Only, ROM, and 3cam lenses, that would be no worse than what the R8/R9 allows ... I can still use the 1-cam and 2-cam lenses with the Leicaflex SL or the "stacked" adapter setup. Leica USA still services R lenses and can do mount updates. Updating all my lenses to ROM would be far too costly, but updating the 2-cam and 1-cam lenses to 3-cam would bring them up to R8/R9 compatibility as well as allow the R Adapter SL the best shot at using them like all the 3-cam models, if they do the four things above. I'd still need to code for lens type to get focal length and corrections, which could be automated with ROM lenses. What Leica has in mind I guess we'll see when they announce it. :-) Link to post Share on other sites More sharing options...
IkarusJohn Posted November 9, 2015 Share #76 Posted November 9, 2015 Hmm, well, although it'd be nice if the dedicated R to SL adapter read ROM chips I don't think it's a given . . . and if it isn't, then it'll just be a one piece version of the current (extremely servicable and uncomplicated) stacked T to M and M to R adapters. I hope it is a stronger likelihood than that! I was never an R user, but as I understand it Leica released the ROM chip as the future. The chip was specific to the lens, and provided EXIF data and corrections specific to that lens, provided aperture information and allowed for aperture adjustment from the camera (if I understand it correctly). Leaving aside aperture stop down, that's a huge step ahead of anything provided for M lenses. Offering that for ROM lenses (I don't know if Leica still offers ROM mount upgrades) presumably does not mean that non-ROM lenses couldn't still be used with the current option of selecting the R lens from the list stored in the camera. I appreciate this is not a given, but Leica would be missing a beat if they ignored what the ROM had to offer - there'd be a lot of muttering into beards about Leica yet again abandoning R users. As for the new R-L adapter being just a one piece of the R-M/M-L stack, that really would be a kludge. The M-L adapter transmits the lens specific 6-bit code to the camera, so your coded lenses appear in the EXIF and such in camera adjustments as may be necessary for that lens are made in the raw file. The 6-bit coding is for M lenses only, so adding the R-M adapter does nothing more than transmit a generic R code to the camera, tripping the list of R lenses. Granted, if you have only one R lens (as I do), this will happen only once (except when I add the 2X extender). But, it's still a "dumb" adapter, if you consider the information stored on the ROM and the potential that provides. As the only code transmitted to the camera with R-M/M-L adapters is the one generic R code, surely I can just put that onto the "dumb" Novoflex adapter I have on order, and then never bother with the setting again. I appreciate I am just filling in gaps with a camera I haven't seen and a lens I haven't used yet ... One thing raised in another post - is the R mount wider than the M mount? The reason I ask is stacking presumably runs the risk of reducing the throat of the mount for R lenses? or am I imaging a non-existent problem?

ramarren Posted November 9, 2015 Share #77 Posted November 9, 2015 R-mount has a 49mm diameter mounting flange, I believe M-mount has a 44mm diameter flange. So yes, there is a potential for shrouding and hard vignetting at both the UWA and long telephoto ends of the spectrum if the adapter tube is not well designed. My recent tests with the R Adapter M don't show any with the Elmarit-R 19 v1 or the Telyt-R 250 v1, which are likely as extreme as I'll use. But there are a bunch of much longer lenses in the R portfolio where it could show up. L (T) mount has a 50mm diameter so it's much easier to design a mount adapter for R that can work perfectly.
