ericborgstrom Posted October 8, 2013 Share #1 Posted October 8, 2013 Advertisement (gone after registration) The Biogon 2,8/21 ZM coded as 21 f/2.8 1134 did not have more than a slight red edge problem on M9. On M (240) the problem is worse; Now on the right side of the picture. Sorry for the slanting horizon. Welcome, dear visitor!

firstlight Posted October 8, 2013 Share #2 Posted October 8, 2013 Damn.. Still waiting for the M but I have the ZM 21/2.8 Can it be corrected in LR easily? Link to post Share on other sites More sharing options...
ericborgstrom Posted October 8, 2013 Author Share #3 Posted October 8, 2013 Damn.. Still waiting for the M but I have the ZM 21/2.8 Can it be corrected in LR easily? Use the graduated filter. It works a bit. The red edge will be somewhat less noticeable using a second profile in LR5 like the one for Summilux 21 or Super-Elmar-M 21. You could also use Cornerfix or best, buy the Super-Elmar-M 21 mm. Welcome, dear visitor!

Dannybuoy Posted October 8, 2013 Share #4 Posted October 8, 2013 Don't apologise for the slanting horizon. It adds a certain tension to the image :-) Link to post Share on other sites More sharing options...
Ecar Posted October 8, 2013 Share #5 Posted October 8, 2013 Damn.. Still waiting for the M but I have the ZM 21/2.8 Can it be corrected in LR easily? Yes, with the DNG Flat Field plugin. Link to post Share on other sites More sharing options...
algrove Posted October 8, 2013 Share #6 Posted October 8, 2013 or best, buy the Super-Elmar-M 21 mm. Now you're talking. Link to post Share on other sites More sharing options...
stickan1 Posted October 8, 2013 Share #7 Posted October 8, 2013 Advertisement (gone after registration) I got the same problem with ZM 21/2.8 and ZM 25/2.8 which worked fine with M9 after firmware 1.176 or so. On M240 there are often problems of the type that you showed. I recommended Adobe Flat Field, get a diffusor! I bought a piece of plexiglas (Claes Ohlsson) and cut it down to 8*8 cm or so and I always have it in my bag when use these lenses. I prefer to only remove the colour cast and handle the vignetting later. Link to post Share on other sites More sharing options...
helged Posted October 8, 2013 Share #8 Posted October 8, 2013 ...best, buy the Super-Elmar-M 21 mm. Unfortunately, even SE 21mm needs a post-fix to get rid of red edges, at least for whitish scenes. Otherwise, SE21 is a stellar lens. And regarding "Red edge problem worse?", I would say that it's comparable to M9, possibly somewhat better, but far from resolved.

firstlight Posted October 10, 2013 Share #9 Posted October 10, 2013 As the new FW is here which stated to solve the red edge problem. Can you comment on the ZM 21? Is it better now? Thanks Link to post Share on other sites More sharing options...
ericborgstrom Posted October 10, 2013 Author Share #10 Posted October 10, 2013 With Firmware Version 2.0.0.11 and the Biogon 21mm at f=5,6 using expo disk I get the following results. First is with auto WB the second is WB in LR5 the middle of the picture as neutral gray. You judge yourself. I judge the red edge problem as smaller. The auto WB is questionable.

Guest porco1962 Posted October 10, 2013 Share #12 Posted October 10, 2013 With Firmware Version 2.0.0.11 and the Biogon 21mm at f=5,6 using expo disk I get the following results. First is with auto WB the second is WB in LR5 the middle of the picture as neutral gray. You judge yourself. I judge the red edge problem as smaller. The auto WB is questionable. Biogon is not a Leica genuine 6bit code lens. So better lens calibration in Firm2.0.0.11 does not affect to biogon theoretically. Link to post Share on other sites More sharing options...
helged Posted October 10, 2013 Share #13 Posted October 10, 2013 A quick test with three wide angle lenses with M240 and the new firmware (2.0.0.11). For a comparable test with the previous FW (1.102), see here and the following posts. First: Leica-M SE21, f8. Red edge still present, possibly somewhat reduced compared with FW1.102, but post-fix is still needed for whitish images. Welcome, dear visitor!

Yes but it does in practise, I tested my Biogon 21 now with the new firmware and it is much better. Here is a white wall. Not perfect, but better. Coded as 21/2.8 ASPH Welcome, dear visitor!

helged Posted October 10, 2013 Share #15 Posted October 10, 2013 Second test shows Carl Zeiss Biogon 21/2.8, 6-bit (hard) coded as 11135/11897 Elmarit-M 21 asph. Photo at f8. Red edge problem much improved compared to FW1.102. Comparable red edge signature to Leica-M SE21. Good. Welcome, dear visitor!

helged Posted October 10, 2013 Share #16 Posted October 10, 2013 Third test is with Carl Zeiss Biogon 25/2.8, 6-bit (hard) coded as 11878/11898 Elmarit-M 24mm asph. Photo at f8. Possibly slight improvement compared to FW1.102. To sum up: Post-processing still needed for all of the tested wides; big improvement for Zeiss 21/2.8 coded as 11135/11897 Elmarit-M 21 asph (but my fav wide is and remains Leica SE21).
