adan Posted August 31, 2018 Share #1 Posted August 31, 2018 Advertisement (gone after registration) I was looking in the used Leica case at the local shop this week, and realized that, including my own 35mm Summicron, I had available four different 35mm lens versions, spanning the decades. So I did a little comparison shot, just to see how they differed in imagery wide-open - f/2 (or f/2.5 - a hint as to one of the types). This is the whole scene, showing the crop areas I'll add below. M10 camera, identical processing of the .dng images, no sharpening added, and the four lenses a, b, c, d are always in the same order. I will reveal which lens is which in a day or so, but will leave it mysterious for the moment, for those who enjoy guessing. It is interesting to see how aberrations, resolution and other characterisitics ("drawing") have been handled over the years. Welcome, dear visitor!

adan Posted August 31, 2018 Author Share #2 Posted August 31, 2018 OK, first detail crops, from the image center. Remember, these are at f/2 or f/2.5. Welcome, dear visitor!

Exodies Posted August 31, 2018 Share #6 Posted August 31, 2018 (edited) No idea which is what but my choice is first b, c, d, a last. ETA after viewing on an iPad. Edited August 31, 2018 by Exodies Quote Link to post Share on other sites More sharing options...
250swb Posted August 31, 2018 Share #7 Posted August 31, 2018 Advertisement (gone after registration) I'll go old to new (I assume this is the order you want answers in?) with b,d,a,c Quote Link to post Share on other sites More sharing options...
Gelatino Posted August 31, 2018 Share #8 Posted August 31, 2018 For me best is a, last is d, b and c in the middle, difficult to separate. IMO none of the four is good averywhere( top left corner) and even d is quite good in the center, so... Quote Link to post Share on other sites More sharing options...
derleicaman Posted August 31, 2018 Share #9 Posted August 31, 2018 Well, seeing you are comparing at f/2 - f/2.5 that rules out some lenses right away. Obviously the Summaron and Summar are out. Any lenses with 1.4 aperture, or are we looking at only a Summarit and Summicrons? Quote Link to post Share on other sites More sharing options...
schattenundlicht Posted August 31, 2018 Share #10 Posted August 31, 2018 I find it hard to rate the examples consistently, as I would rate differently for off-center left vs off-center right, which somehow does not seem to make sense, unless there are idiosnycracies in the lens samples (e.g. mild decentering or other deficiencies). Just curious: Did you apply the respective lens profiles in your M10? Was it set to auto-detection? Was this a mix of 6-bit coded & uncoded lenses? Was lens profile explicitly set to 'off' in your DNG-converter? Which DNG-converter did you use? FWIW, my overall rating would be: a, c, b, d. I am looking foreward to the disclosure Quote Link to post Share on other sites More sharing options...
pedaes Posted August 31, 2018 Share #11 Posted August 31, 2018 I to would say a,c,d,b. The image centre shots seem a tad disappointing for all four lenses. Quote Link to post Share on other sites More sharing options...
pico Posted August 31, 2018 Share #12 Posted August 31, 2018 What was the color temperature of the light. Would it make a difference? Quote Link to post Share on other sites More sharing options...
UliWer Posted August 31, 2018 Share #13 Posted August 31, 2018 (edited) a) seems to be contrastier in the center, but shows some horrible CA top left, whilst b and c hold well against this. a) looks also more reddish than the others. I‘d presume it is of different origin than the others but don‘t dare to say Voigtländer. I cannot make up my mind about d). In the „Hold Sheet“ crop it looks as if there was some shaking (double lines). Similar on the right side. b ) loooks like an older lens: so I dare to guess it is the 1. version of the 35mm Summicron. Since there must be a Summarit involved (adan mentions f/2.5) my next guess is: 35mm Summarit is c). Edited August 31, 2018 by UliWer Quote Link to post Share on other sites More sharing options...
pico Posted August 31, 2018 Share #14 Posted August 31, 2018 (edited) Adan's deep understanding of lenses is intimidating to me. Should I ever receive a rejection of one of my photos which states, "Not sharp enough across the frame." I will frame it. NOT that Adan would make that criticism.

dkmoore Posted August 31, 2018 Share #15 Posted August 31, 2018 My guess is A) 35 summicron ASPH 1 Quote Link to post Share on other sites More sharing options...
farnz Posted August 31, 2018 Share #16 Posted August 31, 2018 I would have thought that was a 35/1.4 Summilux v2 (pre asph) but to my understanding that's ruled out by its full aperture being f/1.4. Pete. Quote Link to post Share on other sites More sharing options...
Ecar Posted September 1, 2018 Share #17 Posted September 1, 2018 OK, there are a few things going on here that I'm not sure I understand, but I'll play too. I'd go for a) being the Summicron ASPH and d) being the Summarit. Then, let's say that is a Summicron v3 or v4 and c) a Summicron v1. Probably completely wrong, but fun. Thanks Andy.

wattsy Posted September 1, 2018 Share #18 Posted September 1, 2018 I'd go for a) being the Summicron ASPH and d) being the Summarit. Yes, I'd be inclined to agree with those two (don't know about the others). The Summarit I owned was very sharp in the centre of the frame but a bit below par outside that.

UliWer Posted September 1, 2018 Share #19 Posted September 1, 2018 I presume is meant to be b ) in #16 and 17... Quote Link to post Share on other sites More sharing options...
Narsuitus Posted September 1, 2018 Share #20 Posted September 1, 2018 I assume the camera was tripod mounted. I prefer the images from the "A" lens. Quote Link to post Share on other sites More sharing options...
