AlanJW Posted October 8, 2009 Share #21 Posted October 8, 2009 Advertisement (gone after registration) I thought the original Zeiss 25 brought up the 28/90 on the M8? (reference article "24/25mm Rangefinder Camera Lenses" on reidreviews.com ) Nevermind - I see that WeinschelA already has a Zeiss25 with the 24/35 flange for M8 so would work on M9 but bring up the 35/135 frames. Yes, what I have learned from this thread is that the flange on the M9 is irrelevant -- I'll needa finder as the viewfinder is not going to be adequate. No pint in changing the flange back. Thanks for all the responses. Link to post Share on other sites More sharing options...
Advertisement Posted October 8, 2009 Posted October 8, 2009 Hi AlanJW, Take a look here Zeiss 25mm. I'm sure you'll find what you were looking for!
sean_reid Posted October 8, 2009 Share #22 Posted October 8, 2009 It's not irrelevant if the lens is hand-coded. If you're going to use the lens selection manual then the flange needn't trigger the correct frame lines. Cheers, Sean Link to post Share on other sites More sharing options...
jonoslack Posted October 8, 2009 Share #23 Posted October 8, 2009 Hi There It was getting on for dusk when I got home, and my presence was required by my wife and her two equine friends. Still, I bunged the Zeiss 25 on the M9, I managed to grab a couple of foliage shots to get the corners and then stuffed it in the saddle bag. It was the first time I've used the 25 on the M9, It was actually a bit of a revelation. First of all, it's perfectly okay to use without a finder - not perfect, but if you aren't wearing glasses, and you look around the edges a bit you can see everything that you're going to get . . rather reminiscent of using a 21mm on the M8. Mine had been coded by John Milich, and brings up the 35/135 framelines, it's correctly recognised as a 24mm by the M9. First of all I should say that taking pictures on a horse is not really a perfect test environment, still, this first crop might be expected to show some CA . . and it doesn't: It's also pretty sharp (incidentally, there was no sharpening added) This is a 100% crop from the top left hand corner . . it isn't absolutely in the plane of focus, but it's close As far as vignetting and colour drift, I reckon these two shots would probably show it if it was likely to happen. Perhaps there is a very slight tendency to magenta vignetting at the corners, but it's pretty minimal and this kind of evening light is pretty telling. Looking at the images my reaction is that the lens doesn't seem quite as brutal on the M9 as it did on the M9 - but that might have been the less than perfect conditions. These were taken at f8, clearly it's hardly a definitive test, but still, it seems to me to show that the Zeiss 25 is likely to be just as much of a winner on the M9 as it was on the M8 All the pictures were taken using daylight white balance.

leicanut2 Posted October 9, 2009 Share #24 Posted October 9, 2009 Wow, the Zeiss 21 picture is good. and even the crop is great. Cheers Jan Link to post Share on other sites More sharing options...
arthury Posted October 9, 2009 Share #25 Posted October 9, 2009 I can just say that my new copy of the Zeiss 21 f/2.8 simply blew me away on the M9!What an amazing lens! I previously had the 25 on the M8 and it was great too, I expect similar behaviour on the M9. FWIW here a sample (with a 100% crop) of the Zeiss21 with M9 A little USM might help to convince the viewers just a little more. I am assuming you are posting an image that's untouched by any form of sharpening? Link to post Share on other sites More sharing options...

HI There Yes - no sharpening - and I think it's just out of the plane of focus as well - still, we all know what grotty corners look like, and it isn't that! I'll try and do something else over the weekend (without sitting on a horse to do it Thanks for bringing it up though. Link to post Share on other sites More sharing options...
fotolebrocq Posted October 9, 2009 Author Share #27 Posted October 9, 2009 Advertisement (gone after registration) Hi Jono, Just the answer that I was hoping for - Sean's Reid's test on the M8 left open to question it's performace at the edges of the FF M9. You have pretty much answered that. Cheers, Tony www.fotolebrocq.com Link to post Share on other sites More sharing options...
jonoslack Posted October 9, 2009 Share #28 Posted October 9, 2009 Brick Wall Test:eek: Here is the brick wall of my office at f5.6 There is a bit of vignetting as you can see (it's a bit worse at f2.8) Crops in the next post Link to post Share on other sites More sharing options...
jonoslack Posted October 9, 2009 Share #29 Posted October 9, 2009 anyway, let us have crops! first of all at f2.8 Centre: Corner: Then at f8 Centre: Corner: I've slightly sharpened these Anyway, you can see the vignetting, but you can also see that the detail is okay (and of course, one can deal with the vignetting easily if necessary). I hope this helps somebody! Link to post Share on other sites More sharing options...
Mauribix Posted October 9, 2009 Share #30 Posted October 9, 2009 So my guess is that (as for the 21) the Zeiss 25 is a winner on the M9. We know about the superb Elmarit 24, and the new little Elmar-M 24... I'm still curious about the Voigtlander. Anyway, IMHO, all the new Zeiss lenses worth every cent you spent on them.

I hope this helps somebody! Hey Jono, Thanks for doing those. I think that was the missing piece of puzzle. My main focus as I test the various lenses on the M9 is how they perform in that area beyond the M8's 1.33 X crop. Thanks for showing us something about this for the ZF25.

Cheers, Sean Thank you Sean - not up to your meticulous standards I'm afraid, but at least it does give an idea. I'm not sure that the vignetting correction isn't a bit too much (there seems to be a very slight tendency to magenta corners) . . . or does that mean it isn't enough? I guess the next thing would be to test the results with some other lenses rather than the 24 elmarit! I think I'll leave that up to you. Link to post Share on other sites More sharing options...
lars_bergquist Posted October 9, 2009 Share #34 Posted October 9, 2009 A relief, as I will use the ZM 25mm shortly (pious hope!) on a new M9. The Zeiss 21mm f:2.8 has been mentioned. Anybody who can tell me about the M9 behaviour of its f:4.5 little sister? The attraction of this lens is of course the same as that of the C/V 15mm: Is is so small and compact. Also, the focal length has always gone well with 35mm. But it is difficult to find a suitable code for it?

I guess the next thing would be to test the results with some other lenses rather than the 24 elmarit! I think I'll leave that up to you. Hi Jono, If the corners are running a bit towards magenta then the camera is over-correcting for the cyan drift (as you suggest). What code are you selecting for it? If you're treating it as a 24, try selecting a 28 mm code for it instead (to back off the cyan drift correction a bit). Cheers, Sean Link to post Share on other sites More sharing options...

The old man from the Age of the 21mm Contax Biogon Lars, if you came from the age of the 21mm Contax Biogon, I guess the f4.5 little sister could not be your cup of tea... The Biogon ZM 21 reminded me of the "old" 21Biogon for Contax G. Now I have to find the brick wall, and shoot! BTW, if I'm not wrong the 21mm Zeiss f/4.5, is classified as "C" for Classic (I can't remember exactly), I think something related to the way it "draws" or "render" images. I was looking for the f/4.5, but when I saw the little size difference I opted for the 2.8 and never regretted! That's so tiny and small! Link to post Share on other sites More sharing options...
