lct Posted February 15, 2015 Share #1 Posted February 15, 2015 Advertisement (gone after registration) 50/1.4 asph vs 50/2 apo at f/2. (M240, tripod, self timer, focus on "IX" with EVF and 10x magnification, 11 MB files) The statuette looks sharper and bokeh is more round shaped with the 50/2 apo (below) but differences are less obvious than with the 50/2 non apo and the 50/1.4 asph shows less vignetting at f/2.

Advertisement Posted February 15, 2015 Posted February 15, 2015 Hi lct, Take a look here 50/1.4 asph vs 50/2 apo. I'm sure you'll find what you were looking for!
Subject Focus Posted February 15, 2015 Share #2 Posted February 15, 2015 Wow the APO is noticeably quite sharper. Quote Link to post Share on other sites More sharing options...
BerndReini Posted February 15, 2015 Share #3 Posted February 15, 2015 The bokeh isn't really rounder. What you are looking at is the shape of the aperture because at f2 the blades are partially closed on the lux, while they are completely open with the Apo cron. 4 Quote Link to post Share on other sites More sharing options...
MarkP Posted February 15, 2015 Share #4 Posted February 15, 2015 Interesting, but in the second image I think the Summilux is off focus or needs to be checked for a calibration problem 5 Quote Link to post Share on other sites More sharing options...
lct Posted February 15, 2015 Author Share #5 Posted February 15, 2015 Interesting, but in the second image I think the Summilux is off focus or needs to be checked for a calibration problem It is just coming back from Wetzlar with a spot on accuracy.

otto.f Posted February 15, 2015 Share #6 Posted February 15, 2015 Interesting, but in the second image I think the Summilux is off focus or needs to be checked for a calibration problem I do think this test is not accurate enough because it didn't rule out focusing errors. The clock seems sharper to me in the first version which should be 50lux I presume. It's better to shoot the clock from an angle of 45 degrees and compare the best focused points instead of the same points. Manmade errors are not uncommon with rangefinders because your eye is not always 90 degrees straight on the viewfinder 1 Quote Link to post Share on other sites More sharing options...

[...]What you are looking at is the shape of the aperture because at f2 the blades are partially closed on the lux, while they are completely open with the Apo cron. Did not try at f/4 and above but it is rounder at f/2.8 as well per my tests. Quote Link to post Share on other sites More sharing options...

indergaard Posted February 15, 2015 Share #9 Posted February 15, 2015 My 50 Lux is definitely sharper than that wide open.... In the center. It isn't as sharp towards the edges, of course. It's not a lens that is made to have a flat field of focus like the 50 APO, so that can't be expected. But in the center it's on par with the 50 APO in terms of sharpness at f/2.

lct Posted February 15, 2015 Author Share #10 Posted February 15, 2015 Did not try at f/4 and above but it is rounder at f/2.8 as well per my tests. Same crops at f/2.8 (1rst pic). Similar if not identical bokeh shape differences can be noticed when comparing 50/1.4 asph to 50/1.4 pre-asph at f/2.8 (2nd pic). Welcome, dear visitor!

algrove Posted February 15, 2015 Share #11 Posted February 15, 2015 This might have finally convinced me to sell my 50/1.4 as I have not used it since getting the APO50. 1 Quote Link to post Share on other sites More sharing options...
lct Posted February 15, 2015 Author Share #12 Posted February 15, 2015 I will possibly sell mine when Leica makes a better 50/1.4 but i don't hold my breath. Same for the current 35/1.4 BTW. I don't like much both OoF renditions around f/2-2.8 but aside from bulkier lenses, i don't see what else i could use when i need sharp results at f/1.4.

How much better can you get than better? , my 50lux is definitely sharper than the image you show. Having had my 50Cron APO now for a few weeks, and whilst the results are really sharp, I am keeping hold of mine for now as i just like the lux look as well.

BerndReini Posted February 15, 2015 Share #14 Posted February 15, 2015 (edited) I do not think Leica will ever make a better 1.4. If the current 1.4 and the Apo are so close, how big and expensive would an improved lux have to be? Also, I think sharpness and focus are perfect with your version of the 50lux. I would love to see a set of comparison pictures of the 50lux vs Apo by people who claim their lux is even sharper. Come on, these results are in line with every comparison I have seen so far, including my own. And again, thanks for doing this.

Please recall today's Lux ASPH was conceived & born in film days 2] Look at the Noctilux and bloat it a tad bit more.. 3] add 50% on the present list Quote Link to post Share on other sites More sharing options...

It was the shot of the statuette with the lux that surprised me. I will see what i can do to comply 1 Quote Link to post Share on other sites More sharing options...
KM-25 Posted February 16, 2015 Share #18 Posted February 16, 2015 This might have finally convinced me to sell my 50/1.4 as I have not used it since getting the APO50. LOL!! Of course you would... Got any stunner shots with either lens to show....? Quote Link to post Share on other sites More sharing options...
BerndReini Posted February 16, 2015 Share #19 Posted February 16, 2015 It was the shot of the statuette with the lux that surprised me. Ali, you are aware that the images are crops from the same picture, the clock being in the center and the statue at the edge, correct? You have to download the images to see them in full. Maybe this is what throws you off. There is a discernible difference, but it is not as big as it seems once you look at the full picture. 2 Quote Link to post Share on other sites More sharing options...
CheshireCat Posted February 16, 2015 Share #20 Posted February 16, 2015 My educated guess is that the statuette is not in focus in the Summilux shot, because the two lenses have a different focus field shape. Also, the background would look much better with the Summilux wide open. 3 Quote Link to post Share on other sites More sharing options...
