Advertisement Posted July 31, 2013 Posted July 31, 2013 Hi Nordvik, Take a look here Zeiss 25mm F2.8 {merged}. I'm sure you'll find what you were looking for!
AlexanderR Posted July 31, 2013 Share #62 Â Posted July 31, 2013 Hi, I red your thread and this makes me optimistic. Â @ll some dngs at infinity would be great with the zm 25 at f2.8, f4 and f5.6 i know pixelpeeping ... Link to post Share on other sites More sharing options...
gpwhite Posted August 1, 2013 Share #63 Â Posted August 1, 2013 Alexander, I think I answered this point on the other thread, but I find the 24 Elmar to be noticeably cripser, contrastier and more saturated at f/4 than the Biogon. That said, I love both lenses because they are already better than other options. The Biogon at f/2.8 is certainly sharp enough and gives a nicer separation than Elmar at f/4. If you shoot primarily at f/4 or f/5.6, then the Elmar will give you images with more bite. The extreme corners of the FF are "smeared" with both lenses... if you want 100% perfect, I would go for the APO 50 ASPH. Â The shots from pragmatist on this thread should be evidence enough... what greater snap and beauty could you want? Â Peter Link to post Share on other sites More sharing options...
AlexanderR Posted August 2, 2013 Share #64 Â Posted August 2, 2013 well these are not full res but whatever... Â I sent the pictures that i posted here to Zeiss and they told me that the zm 25 is not at infinity and that i should send my camera with the lens to oberkochen. They will adjust it perfectly for the ricoh which then should be also perfect on an m9 just because the elmar works so great already on my ricoh and so it does on the m9 obv. Â will see... I will post direct comparison bevore and after adjustment ...even thou no one really gave **** here about sharing some full res dngs at infinity with the zm 25.... Â why i am not taking the elmar is because the zm 25 is going to be my only lens for a while and it has some advantages over the elmar. Perfectly adjusted it schoul have the same resolution like the elmar. It has 2.8 and also close focus at 0.5m instead of 0.7m ... all this at half the price of the leica Link to post Share on other sites More sharing options...
AlexanderR Posted August 2, 2013 Share #65  Posted August 2, 2013 Looks like I will let my dealer to send the tm 25 to Oberkochen with my ricoh GXR. Zeiss looked at the pictures and wrote me that the lens really needs calibration.  When It comes back I will post new comparison between the elmar and the zm 25 and also pre and post adjustment  Thanks all.

Nordvik Posted August 27, 2013 Share #66  Posted August 27, 2013 Did the lens come back ok?  Here are two pictures taken with my ZM 28. 1. @ 2,8. 2. @ 5,6.  http://www.l-camera-forum.com/leica-forum/attachment.php?attachmentid=394828&stc=1&d=1377631654 http://www.l-camera-forum.com/leica-forum/attachment.php?attachmentid=394829&stc=1&d=1377631654  The foreground is 25m away, the house is 1400m away. I think it's finally time to send it in (like I did with the 50mm). Welcome, dear visitor!

AlexanderR Posted August 27, 2013 Share #67  Posted August 27, 2013 Advertisement (gone after registration) Hello Guys and Hi Nordvik,    The Zeiss ZM 25 came back. Its such an outstanding lens! But I bought a new Leica Elmar-M 24 3.8.  What a way to start this with a paradox but I will explain: - What I love about the zm 25: warm color cast, wonderfull point lights (stars), . .even without hood very flare and ghost resistent. . .at F8 corners are as sharp as Leicas corners.  What I disliked about the zm 25: longer then elmar and heavy front elements! It pulls too . .much -> no grip and comfort with gxr Ricoh. . . corners are softer even at 5.6 then the Leica . . Elmar at even wide open (F3.8) . . no lenshood.  And then there was a minor problem with the focus ring after re-adjustment in Oberkochen. Also they put way toooo much oil / moisture in the mechanism and it actually started dripping around the back element!!! Also the back element had ?water? spots all over it. I guess they forgot to clean it or what. And at my last inspection there were 4 or 5 BLACK spots of dust in the mid section of the optical elements. Somewhere in the iris area where the elements are very small actually. All this gave me a very bad feeling.  The Leica is phenomenal. The corners are as sharp as the center even at 3.8 on APS.C Sensor. Its much shorter then the Zeiss and also its no where as heavy in the front section as the zm25 was even with the lens hood on  Here is the comparison: click on it to go to flikr and thenwith the right button u can choose full res / original zm 25 pre and post by Zorki-IV, on Flickr  Norvik,  You could send the zm 28 in but I have to tell you the 28 isnt specificly known to be sharp wide open... compare the MTF charts from zeiss with maby the zm 25 and you will see for you self. But it kind of looks like your 28 cant reach infinity as well... Link to post Share on other sites More sharing options...

jaapv Posted August 27, 2013 Share #69  Posted August 27, 2013 Interesting topic for me as well.I have the 24 Elmar, but I was using a Zeiss 35 ZM today, and I'm disappointed with results. Should this lens work correctly on my M9? I original purchased it for the NEX7 in anticipation of my upgrade to Leica. Edit. I'm sorry if it appears that I'm changing the original question. It seems related but perhaps a new thread would be better. I am using a C-Biogon 35 on my MM and it is very sharp, focussing is correct. Link to post Share on other sites More sharing options...
AlexanderR Posted August 28, 2013 Share #70 Â Posted August 28, 2013 Well I do not know about the c-biogon but the f2 35 biogon I also tried and it also does not reach Infinity-focus. It needs adjustment! So far I have had 100% yield of Biogons that were out of tollerance for the focal flange distance... what are you doing ZEISSSSSS!? I didnt try c biogon thou. Â This year a M Zeiss was supposed to be released. Well, its only going to be announced and release will fallow in early 2014... but I could not find out what focal lenght and f it will be! Â And please comment on the comparison... Link to post Share on other sites More sharing options...
Nordvik Posted August 29, 2013 Share #71  Posted August 29, 2013 The Elmar looks better in the corner for sure. If they are from an APS-C sensor that makes it even worse for the Biogon.  I don't take many landscape photos and are not too concerned about the corner definition performance at infinity (your objects are not at infinity either). A predictable field curvature are probably more important for me (a wavy field curvature sounds like a nightmare).  Here are a crop at far right from the same 5,6 picture as above (M9).  The 28mm went to Oberkochen today for adjustment.  http://www.l-camera-forum.com/leica-forum/attachment.php?attachmentid=395203&stc=1&d=1377807306 Welcome, dear visitor!

AlexanderR Posted August 30, 2013 Share #72  Posted August 30, 2013 let us see what happens!  Yeah it is aps-c  I still have the option to get a 21 super-elmar 3.4 asph. which is good on aps-c as but worse then a elmar 24 on full frame. Link to post Share on other sites More sharing options...
Nordvik Posted September 14, 2013 Share #73  Posted September 14, 2013 Got my 28mm back from Oberkochen today.  "Diagnosis: MTF ok. FFD out of tolerance. Dust inside. Service provided: Lens disassembled and cleaned. FFD adjusted. Performance and function test, test images. This service was covered by our warranty."  Looks alot better now. 5,6 & 2,8:  http://www.l-camera-forum.com/leica-forum/attachment.php?attachmentid=397923&stc=1&d=1379158046 http://www.l-camera-forum.com/leica-forum/attachment.php?attachmentid=397924&stc=1&d=1379158462 Welcome, dear visitor!
