jaeger Posted October 15, 2020 Share #1 Posted October 15, 2020 Advertisement (gone after registration) It seems like 50mm lux ASPH has so many goodies, is it as good as 50mm APO when both shooting at f/2? I don't own 50mm APO so please share your findings. Link to post Share on other sites More sharing options...
Advertisement Posted October 15, 2020 Posted October 15, 2020 Hi jaeger, Take a look here 50mm summilux at f/2 vs 50mm summicron APO. I'm sure you'll find what you were looking for!
wda Posted October 15, 2020 Share #2 Posted October 15, 2020 (edited) For any incremental improvement in performance, you would pay a steep premium. When I don't need the speed, I choose my late version Summicron rather than carry the extra weight of my Summilux. It all depends on your regular needs.

insomnia Posted October 15, 2020 Share #3 Posted October 15, 2020 In the center it's comparable, over the whole field the APO dominates at f/2. Btw., the APO is not much lighter than the Summilux. I went back to the Summilux as I prefer the rendering and the extra stop over edge-to-edge sharpness. As additional benefit, the 35 FLE could join the gang due to additional funds 😉 Link to post Share on other sites More sharing options...

I moved from 'lux to APO as I wanted 'the best', and it is not just about sharpness, also colour, clarity and performance in all areas. To quote from another APO thread - it just delivers and never gets in the way. That said, I have never been unhappy with my Zeiss 50mm Planar or Elmar-M!

lct Posted October 15, 2020 Share #5 Posted October 15, 2020 At f/2, the 50/2 apo has less field curvature than the 50/1.4 asph which has a somewhat smoother bokeh but the bokeh balls of the apo are rounder. 1 Link to post Share on other sites More sharing options...
evikne Posted October 15, 2020 Share #6 Posted October 15, 2020 The "bokeh balls" from a Summicron at f/2 will of course always be rounder than a Summilux at f/2, because the Summicron's aperture blades are wide open, while the Summilux is slightly stopped down. At f/2.8 a Summicron will still retain an advantage in this regard, because one stop down shapes a rounder aperture than two stops. 1 Link to post Share on other sites More sharing options...

evikne Posted October 15, 2020 Share #10 Posted October 15, 2020 (edited) A more interesting (fair) comparison would be the Summilux ASPH at f/2.8 against the APO Summicron at f/4.0 (both stopped down 2 stops). That would show the effect of the number of aperture blades. Edited October 15, 2020 by evikne Link to post Share on other sites More sharing options...

jaeger Posted October 16, 2020 Author Share #13 Posted October 16, 2020 oh guys thank you guys! I remember now, the summilux has curvature background which I like but aperture star edges which I'm not crazy about. I prefer vintage look so the summilux will stay with me for a while. 1 Link to post Share on other sites More sharing options...
didier Posted October 16, 2020 Share #14 Posted October 16, 2020 I find the rendering of the APO unique (clarity, colors), and I prefer it to the ‘lux, particularly in the close range where the APO is much better. I also prefer the bokeh of the APO Didier 1 1 Link to post Share on other sites More sharing options...
easy_action Posted October 17, 2020 Share #15 Posted October 17, 2020 For a lens of this value I shouldn't have to worry that shooting at certain apertures might give these results. I haven't experienced the same with the APO-Summicron. Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members!

Any lens, regardless of price, will do the same. Shoot towards dappled light, adjust the aperture to f/4 or f/5.6,and focus on an object that's at the minimum focus limit and the out of focus specular highlights will look like circular saw blades instead of balloons. ... Unless you meant only having the top of the subject's head in the bottom right corner, which would qualify as 'operator error'. Pete.

Typical OoF rendering of the Summilux 50/1.4 asph. You would get rounder bokeh balls with a 50/1.4 pre-asph or a 50/2 apo if you prefer that. Matter of tastes but i don't think the price has anything to do with that. I prefer the 6 diaphragm blades of the cheaper Elmar-M 50/2.8 personally, don't ask me why...

easy_action Posted October 18, 2020 Share #18 Posted October 18, 2020 The combination saw blade + bull's eye bokeh is difficult to 'unsee' once you have noticed it. I lost faith in the lens a bit after that, which was frustrating as otherwise there is a lot to like. Happily there are plenty of alternatives available. 1 hour ago, farnz said: Unless you meant only having the top of the subject's head in the bottom right corner, which would qualify as 'operator error'.
