alun Posted July 29, 2009 Share #21 Posted July 29, 2009 Advertisement (gone after registration) OK, turned out to be more interesting than I first thought. I'll be wrong with all the others... (Can we all be wrong? I imagine we can.) At least a 50mm, probably Summilux pre-Asph, at 1.4, and it is either on an M8, or (just possibly) using chromogenic B&W negative. It's defintely not conventional B&W film. And much more likely a desaturated digital file (the crop suggests digital rather than film grain). Link to post Share on other sites More sharing options...

adan Posted July 29, 2009 Author Share #23 Posted July 29, 2009 OK, you guys stretched it out to 22 posts, so I'll give: Pretty good scores, too. 50 'lux pre-ASPH (about a 1968 model, not that the optics changed over the years) - M8, ISO 640, crop uprezzed a bit to soften the digital signature and prevent some mathhead from calculating the original pixel dimensions.

Pangur Ban Posted July 29, 2009 Share #25 Posted July 29, 2009 I'm impressed with how many got it spot on, or worked out it was a 50mm or an M8 photo for that matter. Good show. I would encourage those who make their opinions to back them up with an explanation as that helps the rest of us. Can we have some more please, there's lots to learn.

JBA Posted July 30, 2009 Share #27 Posted July 30, 2009 Advertisement (gone after registration) I'm impressed with how many got it spot on, or worked out it was a 50mm or an M8 photo for that matter. Good show. I would encourage those who make their opinions to back them up with an explanation as that helps the rest of us. Can we have some more please, there's lots to learn. Since I basically nailed it, I'll explain my reasoning. First of all, I own a pre-asph 50 'Lux (1989 serial #) and use it a lot on my film Ms.This lens is also called the Version 2, and was designed by Walter Mandler. It is razor sharp and its color rendering is brilliant. I shoot wide open most of the time and recognize a number of its characteristics, particularly the bokeh. Wide open, the 50 'Lux renders a bokeh that looks like it was thrown out of focus and then jolted slightly out of phase. The effect is of a doubling-up, and in some cases it can look rather jagged (the term "harsh" often seems to be applied to this type of bokeh). Pinpoint light sources in the OOF will be rendered as doubled-up elipses oriented along concentric circles from the center of the frame, as is the case in the upper left of Andy's photo. This is due to spherical aberration and indicates spherical optics. An aspherical lens will render these pinpoint light sources as soft globes because the spherical aberration is corrected almost out of existence. Second, the perspective in the photo seems slightly longer than a 50 but quite a bit shorter than a 90. I am used to seeing the 50 'Lux on film, and in a photo like this where the subject is sandwiched between a foreground bokeh and background bokeh, the perspective will be slightly less compressed. First clue that it was probably shot with an M8. Third, I am a film slut and did not recognize anything resembling a film grain that could have been used under these ambient conditions. Ilford PanF or Delta 100 might give a similar looking grain, but under these lighting conditions both films would have been much too slow. Any 400 film would have had a more pronounced grain in the 100% crop. The sharpness and relative lack of grain under those lighing conditions made it pretty clear that it was a digital photo. That, in a rather large nutshell, was my thinking in deducing the lens and camera. There are lots of lenses out there, so I could just as well have been wrong.

Sandokan Posted July 30, 2009 Share #29 Posted July 30, 2009 24 Aspherical Elmarit (which on M8 is field of view of 32mm, which gives about 1.1m horizontal view when standing 1m away from subject) and I guess you are about 2m away. Razor sharp on close up and depth of field covers short collar to nose (about 6cm). Ravi Link to post Share on other sites More sharing options...
ArtZ Posted July 30, 2009 Share #30 Posted July 30, 2009 Wow! Just one answer? (Thank you Sandokan!) Is really so easy to find the signature of this lens that you don't want to give a try...? Alors ? Link to post Share on other sites More sharing options...
adan Posted July 30, 2009 Author Share #31 Posted July 30, 2009 ArtZ - I'd say an ASPH 28 (M8), but do not have the connoisseurship to distinguish the f/2.8 from the f/2 in this case for certain. I'll roll the dice and say the 'cron, because of the amount of background blur, and the fact that the lens seems to be slightly stopped down (bright highlight blurs top left in the detail are faintly polygonal in shape - 10 blades but both Leica 28's would match that). It's either shot @ f/2.2, or it's one of those lenses where the aperture blades are just slightly visible once Leica has adjusted the max aperture precisely.

JBA Posted July 30, 2009 Share #32 Posted July 30, 2009 I'll guess 35 'Lux Asph. Link to post Share on other sites More sharing options...
NB23 Posted July 31, 2009 Share #33 Posted July 31, 2009 I will say 50mm biogon, a lens I have never used. Edit: I see it's a pre-asph lux (it will teach me to answer before reading entire posts). I was 90% sure it was the lux pre-asph because of the funny unfocus, but then again, apparently the Biogon is also like that, so I went for the long shot. But it was obvious it was a 50mm shot. As for the second shot, I will go with 35mm lux asph simply because of the apparent sharpness wide open. Link to post Share on other sites More sharing options...
ArtZ Posted July 31, 2009 Share #34 Posted July 31, 2009 Thank you, guys! I found this thread more interesting than "What lens(es) should I take for..." because you have to use your brain and knowledge on something real. Thank you Andy. But apparently most LUF users disagree or they're just afraid of being wrong... so I give up. This picture of my dad (92 yo) was taken on July 15th, 2009 at Bilbao's market at ISO 320, 1/180, f/2 (maybe f/2.4 -I have a doubt) with a CV Nokton 35/1.4 which has not ASPH element(s). Bravo NB23! I have only corrected WB on Photoshop CS4 from 4550 ºK Tint +24 (M8 in mode AUTO WB) to 3800 ºK Tint +20 NB23: The second image is just a 100% crop of the first one. It's not a second shot. Cheers PS: Andy, my Summicron 28 was at Solms at that time. Leica had replaced my first M8 (shutter problems) for a new one. They also asked me to send a couple of lenses to check possible focus issues in the new camera. I sent two Summicrons: 28 ASPH and 90 APO which can be tricky on a M8. Mine had to be adjusted previously a couple of times (Oct 2007 and Dec 2008). Now they are perfect. Link to post Share on other sites More sharing options...
luigi bertolotti Posted July 31, 2009 Share #35 Posted July 31, 2009 I entered this thread only now: LOT OF FUN !!! Really a fine game which pairs well with the "Do you know the world ?" that is running by some months and is still well alive. In my opinion, if this fun game has to continue, it could be nice to establish just a pair of rules: a) specify if it's a film Leica or M8 the "basic pic" (crops are welcome and useful for hints)must be the full frame or very next to. c) (maybe) specify Leica/no Leica lens, or limit to Leica lenses : many people, I seem to understand, have numbers of 3rd parties lenses ranging from old Canons to Russian to Hexanon, then there are the CV, the Zeiss... realy a too widespread universe. ... and I'm very happy to admit honestly that I had guessed for the Summilux for the first pic...

Sandokan Posted July 31, 2009 Share #36 Posted July 31, 2009 I think we need a rule that the lens must be used at its widest aperture. Not fair to stop down a lens as then the number of variables changes dramatically... PS - I find this also more fun than "what lens should I buy / take...".

ArtZ Posted July 31, 2009 Share #37 Posted July 31, 2009 Luigi, Sandokan, I agree with you both. Some rules are needed but I think it should be opened to all lenses without distinction of brands (Leica, Zeiss, CV, Canon... that's the part that make the game interesting...) So I would see three rules. The first one concerning the aperture (only wide opened lenses or giving the value when they're not wide opened); the second one depending on the year (something like old and modern lenses) and the third one if it's film or digital.

Cheers Hum... let me think a little.. ok for the aperture, in the sense of giving the value (or at least something like "a little closed" or simply "WO/no WO"... anyway these can be hints given during the "chase").. wideopen only could be a bit too much limitative. I'm not so in agree about the "old/modern" spec... can be one the funny factors (discover supersharp pics from a lens of the '30s...anyway, as above, can be a hint ). As I said film/digi is mandatory... with the raccomendation of no exaggerations in PP... Link to post Share on other sites More sharing options...
Sandokan Posted July 31, 2009 Share #39 Posted July 31, 2009 I agree - any manufacturer, but must be taken wide open but camera used must be given. No hints for f stop; no PP distortions. Maybe if no correct entries, then hints for distance or age of lens... Link to post Share on other sites More sharing options...
