Riley Posted January 12, 2009 Share #1 Posted January 12, 2009 Advertisement (gone after registration) Im interested in M mounts as they fit to G1 via adapter has anyone got any compatibility issues to report ? lenses tha do fit might be good to hear too.....

Advertisement Posted January 12, 2009 Posted January 12, 2009 Hi Riley, Take a look here G1 M mount compatibility. I'm sure you'll find what you were looking for!
Vivek Iyer Posted January 12, 2009 Share #2 Posted January 12, 2009 Not sure I understand your questions, Riley. The adapter I made (out of an OUFRO) and the RayQual adapter I bought have no issues at all mounting on the G1. If a lens does not fit the RayQual adapter, then it is not possible to mount it and use it on the G1. As simple as that. I did not buy the Novoflex adapter and have no intentions to buy one either!

Im interested in whether all M lenses fit, b/se some M mounts protrude inside the body, lenses like Voigtlander UWA but now back to the adapter, are you saying that there are issues with different adapters ? that could be important too.

Vivek Iyer Posted January 12, 2009 Share #4 Posted January 12, 2009 Riley, Let me put it this way. Your proximity to RayQual pretty much seals which adapter (which is the better one anyway) you want! CV15/4.5 is not a problem at all. I do not forsee any problems with the 12mm lens either. When I mount the Rayqual on the G1, i hear a faint (but distinct) click to know that it is locked. When I mount anything (including adapters) with an M mount on the adapter, I hear, again a distinct click to confirm that it is mounted correctly and is ready for action. It may sound (pun intended, gosh I am on a roll here! ) silly but it is important to know that your lenses are safe. Besides this sound thing, there is this tiny little black disc in the rear (RayQual) which shields/insultaes all the electrical contacts in G1. If a lens hits this (say an old SA) then you can not mount it on the adapter itself. This would also prevent you from mounting any lens that would potentially damage the G1 by crashing into its shutter (which is located very close to the lens mount). So, without sounding redundant, Japan is close to Australia, right? Link to post Share on other sites More sharing options...

Vivek, thanks for the run down, mostly this is an information quest for 4/3rds usres that dont have any M mounts on hand, and dont want to purchase something that might not work out. So, without sounding redundant, Japan is close to Australia, right? with the love of ebay, I've imported gear from all over the world, UK, Germany, France USA,....oddly enough except Japan... ..

marknorton Posted January 12, 2009 Share #6 Posted January 12, 2009 Only lens I have found which cannot be used from recent/current production is the 50mm Elmar. It will mount but you definitely don't want to collapse it. The key thing is that the current generation Leica wides 21/2.8 ASPH, 24/2.8 ASPH, 28/2 ASPH, 35/1.4 ASPH work fine.

audidudi Posted January 12, 2009 Share #8 Posted January 12, 2009 CV15/4.5 is not a problem at all. I do not forsee any problems with the 12mm lens either. As soon as my G1 arrives, I will mount my Nikon-mount CV 12mm on it and confirm that it clears ... can't imagine why it won't, though, as it works fine on my DMC-L1. I am really excited about the prospect of a high-res camera with a compact 24mm lens ... here's hoping the two complement each other! Link to post Share on other sites More sharing options...
Vivek Iyer Posted January 12, 2009 Share #9 Posted January 12, 2009 It (12mm CV) shouldn't pose any problems. Terry has shown (in that dreaded thread) some shots with her 12mm mounted on the G1 via the Milich LTM adapter. Link to post Share on other sites More sharing options...
jebir Posted January 13, 2009 Share #10 Posted January 13, 2009 Hi audududi, As soon as my G1 arrives, I will mount my Nikon-mount CV 12mm on it and confirm that it clears ... can't imagine why it won't, though, as it works fine on my DMC-L1. Hmm... are you talking about the Cosina-Voigtländer 12/5.6? That lens protrudes so far behind the mounting flange that it will enter about 6 mm into the chamber of the G1 and about 26 mm into the mirror box of the DMC-L1. I wonder how you can mount it so it clears the mirror flip in the DMC-L1? Cheers, Jens (the 3/4rds guy Riley mentioned above) Link to post Share on other sites More sharing options...

I believe that you are confusing the Nikon register with those of the 4/3rds and the M 4/3rds. There is (AFAIK) only one 12/5.6 CV lens and it was offered in two mounts (LTM and Nikon that requires a TRUE mirror lock up). Link to post Share on other sites More sharing options...
jebir Posted January 13, 2009 Share #12 Posted January 13, 2009 Hi Vivek, well, they were pretty much fast estimates in my head based on the following figures: LTM CV-12/5.6 protrudes ~14 mm behind its mounting flange (as measured by a friend of mine) Flange-back of LTM = 28.8 mm Flange-back of 4/3 = 38.58 mm Thickness of Panasonic's 4/3 --> µ4/3 adapter = 19.33 mm so the flange-back of µ4/3 = 19.25 (the difference between 4/3 flange-back distance and the thickness of the 4/3 --> µ4/3 adapter) Now, instead of making sloppy approximations in my head, Ill make proper calculations: If the lens enters an LTM camera's chamber by ~14 mm it means that it must end about 28.2 mm - 14 mm = ~14.8 mm in front of the film/sensor plane which is the same for all systems. µ4/3: So the lens should enter into a µ4/3 body by its flange-back distance minus the lens' distance from the sensor plane: 19.25 mm - ~14.8 mm = ~4.45 mm 4/3: For the DMC-L1 body (4/3 system), in the same way the extension into the chamber should be 38.58 mm - ~14.8 mm = ~23.78 mm Hmmm. those numbers are ~1.5 - 2.2 mm less than what I calculated in my head... so I must have made miscalculations before... sorry about that. Nevertheless, my point is that I'm surprised if a lens, sticking in almost 2/3 of the way from the flange to the sensor, will clear the mirror in any SLR. Maybe it is possible by some trick that I'm unaware of? As I don't own the adapter nor the lens, I trust those who measured them, but there is a possibility that those initial values are incorrect although not by by a large amount - I think. Cheers, Jens.

Riley Posted January 13, 2009 Author Share #13 Posted January 13, 2009 Jens, audidudi is not your average user it wont clear the mirror, he does indeed shoot the CV mirror up I believe this is it situated on his L1, and isnt it nice ! Link to post Share on other sites More sharing options...

Yes!!! Very nice indeed! Thanks for explaining that Riley. I wasn't aware that the L1 could lift the mirror. Or is he doing a trick? Cheer, Jens.

audidudi Posted January 14, 2009 Share #16 Posted January 14, 2009 I wasn't aware that the L1 could lift the mirror. Or is he doing a trick? There's no trick. I'm using the NLA Nikon F-mount version of the CV 12mm/f5.6 lens. When you engage Live View on the L1, the mirror flips out of the way to expose the sensor. When you fire the shutter, the mirror flips back, makes contact with the lens barrel (but very softly, as there isn't even a mark on it after several hundred exposures), then flips out of the way during the exposure. It's all very Mickey Mouse, but it works well enough and IMO, the results have been worthwhile. FWIW, I also have the 15mm/f4.5 version as well...

audidudi Posted January 14, 2009 Share #18 Posted January 14, 2009 But hasn't Oly done a very good job on their wide zooms and kept them reasonably small? Sure, but they're still orders of magnitude larger than the CV 12mm fixed lens (which was / is an important consideration for me) and at the time I bought the CV 12mm, it was less expensive than either the Oly 7-14 or 11-22, the only two options then available. If you search the archives, you'll find that I never touted this solution as a universal one or even claimed that it made sense, only that it served my particular purposes. As it turned out, though, given that Cameraquest is asking $1300 for its last NOS F-mount CV 12mm, I may have actually made a good investment as well, because that's nearly twice what I paid for mine!

Bob Ross Posted January 14, 2009 Share #19 Posted January 14, 2009 But hasn't Oly done a very good job on their wide zooms and kept them reasonably small? Hi Terry, I have the 11-22mm for my wide angle 4/3rds work and it is quite chunky. Filter size is 72mm and dimensions are 75mm X 92.5mm & weight 485g. It is a lot faster at f/2.8-f/3.5 and balances well on the E-1 or E-3, but would sort of overpower the G1. It is very well corrected for a zoom in this range.

Is it LTM? Also, I have used the last few days quite extensively the Elmar 50/3.5. Very ok and just use a tape on it.
