CheshireCat Posted February 17, 2016 Share #1 Posted February 17, 2016 Advertisement (gone after registration) Just got a v3 non-APO 90/2 (serial 35*), and compared it with the APO 75/2. I expected to be turn down by color rendering, but I have to admit the 90/2 is amazing. Perspective is very similar (15mm difference). The 75 "user interface" (rings and stuff) is smoother. About same weight. 75 a little smaller, not dramatically. 75 sharper wide open but you have to pixel-peep. 75 has better color aberration correction but only a trained eye will see the difference. 75 has a hood that blocks in place if rotated. 75 new is 4 times the price of a good used 90. First test. Both on M240 at f/2, natural light. Can you tell which is which ? Welcome, dear visitor!

Advertisement Posted February 17, 2016 Posted February 17, 2016 Hi CheshireCat, Take a look here Summicron-M 90 vs APO Summicron 75. I'm sure you'll find what you were looking for!
lm_user Posted February 17, 2016 Share #2 Posted February 17, 2016 I would guess the left photo is the 75 - bokeh is slightly different. Right or wrong - the difference is so subtle that the lens choice is not going to ruin a great photo or make a poor photo great..... Quote Link to post Share on other sites More sharing options...
lct Posted February 17, 2016 Share #3 Posted February 17, 2016 Too small pics to be 100% sure but if those were out of camera pictures, i would say the right one is the 75. More contrast, more sharpness and more DoF. 2 Quote Link to post Share on other sites More sharing options...
CheshireCat Posted February 17, 2016 Author Share #4 Posted February 17, 2016 These are straight OOC, white balanced on the same spot. 1 Quote Link to post Share on other sites More sharing options...

Jeff S Posted February 17, 2016 Share #6 Posted February 17, 2016 Pedant alert....perspective is same (unless you move), but angle of view is 32 vs 27 degrees. Also min focus distance is 30cm less with the 75. Jeff 1 Quote Link to post Share on other sites More sharing options...
CheshireCat Posted February 17, 2016 Author Share #7 Posted February 17, 2016 Advertisement (gone after registration) Also min focus distance is 30cm less with the 75. Very true, and very useful. Quote Link to post Share on other sites More sharing options...
adan Posted February 17, 2016 Share #8 Posted February 17, 2016 Right-hand or second shot is 90mm. As I recall, you prefer electronic viewing. So you avoid the one huge difference between any 75 and any 90 - the 90 framelines are much less accurate at longer distances (they are actually about a 105mm field of view). Much as I like both the 90 pre-ASPH you have and the tiny Tele-Elmarit-M, I just got tired of having to throw away 22% of my precious megapixels cropping to the picture I thought I was getting. The 75mms actually crop tighter than the M9 lines at 0.7 meters - but shooting in that range, I'm generally aiming for "as tight as possible" anyway, and losing a bit more junk around the edges is usually a plus (if not - it's digital - I reshoot). But the 90 pre-ASPH is definitely the "poor man's 75 Summilux" in terms of rendering - nice! 1 Quote Link to post Share on other sites More sharing options...
NB23 Posted February 17, 2016 Share #9 Posted February 17, 2016 I think its extremely obvious that the left image is fromthe 75. Quote Link to post Share on other sites More sharing options...
iwc852 Posted February 18, 2016 Share #10 Posted February 18, 2016 the plane in focus is a bit closer on the left image - that's why I initially thought the right one has been made with the 75 (looking at the yellow bits at the top of the frame)...

CheshireCat Posted February 18, 2016 Author Share #11 Posted February 18, 2016 You guys have good eyes ! Left is 75, Right is 90. Adan, thanks for the useful info. I will post more comparisons soon Quote Link to post Share on other sites More sharing options...
bocaburger Posted February 18, 2016 Share #12 Posted February 18, 2016 (edited) the 90 framelines are much less accurate at longer distances (they are actually about a 105mm field of view). Much as I like both the 90 pre-ASPH you have and the tiny Tele-Elmarit-M, I just got tired of having to throw away 22% of my precious megapixels cropping to the picture I thought I was getting. True about the lines, however it never occured to me to simply accept the 90mm frameline framing and then crop later. Rather, I taught myself quickly back in the film days how much outside the 90mm lines is actually recorded, and from that point on, framing accurately has not been an issue. I did have to make some slight adjustments to my estimation going from an M4 to an M6 (M6 50 and 90 frame lines are a bit tighter) and now again with the M240 which is calibrated for 2m. I have both the 90 pre-ASPH and thin T-E, the former I prefer to the e46 Elmarit as it seems to perform about the same from f/2.8 down (except at close focus), is not much heavier or bulkier, and affords me a nice rendition wide-open for portraiture. The thin T-E despite it's tendency to flare if not careful, remains a staple in my travel bag. I never really warmed up to the 75mm focal length, however I used a CV 75/2.5 rather than the T-E when I had an M8. Still own that lens, got it cheap, now use it on my NEX 6.

EoinC Posted February 20, 2016 Share #13 Posted February 20, 2016 Nice kitchen set, either way. I've been thinking about adding a 90 Summicron, but not sure I'll get that much use at the moment. Quote Link to post Share on other sites More sharing options...
