Advertisement Posted October 14, 2015 Posted October 14, 2015 Hi keithlaban.co.uk, Take a look here Comparison C Sonnar T* 1,5/50 & Summilux-M 50mm f/1.4 ASPH?. I'm sure you'll find what you were looking for!
vanGeist Posted October 14, 2015 Share #2 Â Posted October 14, 2015 Maybe the Rockwell? Â Summilux http://www.kenrockwell.com/leica/50mm-f14-asph.htm#bokeh Sonnar http://www.kenrockwell.com/zeiss/zm/50mm-f15.htm#bokeh Link to post Share on other sites More sharing options...

tobey bilek Posted October 15, 2015 Share #4 Â Posted October 15, 2015 Rockwell example should cinch it for you. Â Â Â My son did a test with my `Lux ASPH and his current 50 Summicron. Â Lux was far ahead again Link to post Share on other sites More sharing options...
SiggiGun Posted October 22, 2015 Share #5 Â Posted October 22, 2015 If your concern is BOKEH, there is no question the answer is Zeiss. Take a look on my Flickr account. And go to the Sonnar section Link to post Share on other sites More sharing options...
Stein K S Posted October 25, 2015 Share #6 Â Posted October 25, 2015 If your concern is BOKEH, there is no question the answer is Zeiss. Take a look on my Flickr account. And go to the Sonnar section Thanks! I must admit.... That Sonnar really has a MOST beautiful bokeh in my eyes. Even how hard I would like to believe that Leica lenses pretty much "tops" on all/most properties... Â Regards, Stein Link to post Share on other sites More sharing options...
keithlaban.co.uk Posted October 25, 2015 Author Share #7  Posted October 25, 2015 Advertisement (gone after registration) Thanks, Siegfried.  I bought the Sonnar for some upcoming people projects and so far I'm delighted with the OOF qualities and isolation that this lens delivers.  My question was prompted by the thought that the Summilux could serve as an all purpose lens with good bokeh and yet much sharper when stopped down. But, hell, at the comparatively low price of the Sonnar it'll be a keeper with the possible addition of another 50mm in the future. Link to post Share on other sites More sharing options...

I don't know if it's really that comparatively low in price; if I were to part with US$1000, I might opt for ta nice 50 Rigid. But for my money, if I were to use it for portraits, would have focus optimized for f/1.5. Otherwise it will shift until 2.8 and the bokeh you cherish is dissipated.

Mornnb Posted October 25, 2015 Share #12 Â Posted October 25, 2015 Why, when I can get an M240 for every focus shifting lens and use the rangefinder for the rest? The A7R will let you adjust the centre zoom in to different locations. Meaning it can not only counter for focus shift, but also field curvature.

keithlaban.co.uk Posted October 25, 2015 Author Share #13 Â Posted October 25, 2015 I've no interest in the A7R. Link to post Share on other sites More sharing options...
fiftyonepointsix Posted October 25, 2015 Share #14  Posted October 25, 2015 Then you might as well get an a7** for every focus shifting lens and forget about the rangefinder altogether. The Sonnar formula lenses sit much closer to the image plane compared with most lenses. It does much better on a Leica Digital sensor, which is optimized for such lenses.  With a little practice, you learn to deal with focus shift: focus with the RF then back off a little, or leave the RF image slightly off perfect coincidence.  As much as I like my C-Sonnar,  Window Shades by fiftyonepointsix, on Flickr  I like the original Sonnars even more. I have a collection of Sonnars and Sonnar formula Jupiters, Nikkors, Canons, Tanars, ... going from 1934 to the C-Sonnar. Link to post Share on other sites More sharing options...

Field curvature on the C-Sonnar is greatly reduced compared with the original lenses. Field curvature is greatly reduced in the reformulated Sonnars of the 1940s, but those are rare and one in mint condition will cost almost as much as a new C-Sonnar.

Mornnb Posted October 26, 2015 Share #18  Posted October 26, 2015 I find the EVF to be adequate, whereas I loath the Sony A7 cameras.   The main issue with the Olympus EVF is the lack of dynamic range and contrast, it gives you a very inexact impression of the exposure and final image. However, compared to the A7 EVF I find it to have less noticeable aliasing, it spite of lower resolution. IMHO, both EVFs are far from ideal.  hiepphotog, on 15 Oct 2015 - 14:08, said:http://www.raylarose.com/2013/10/1st-compare-zeiss-c-sonnar-vs-leica-summilux-m/ http://www.adjustablebias.com/blog/   As you can see here, the Summilux ASPH has superior, smoother and less distracting bokeh. Link to post Share on other sites More sharing options...
fiftyonepointsix Posted October 26, 2015 Share #19 Â Posted October 26, 2015 The Summilux shows out-of-focus regions characteristic of residual astigmatism. The price you often pay for having flatness of field. Â Bokeh is a matter of taste. Lenses that are not critically sharp are often preferred for portraits.

Thank you for the link to how to shim a Jupiter-3 lens. I tried this with a Jupiter-8. Using kitchen aluminium foil I got this result (before-after, three layers of aluminium foil. The index for the aperture went from 2,0 to between 2,8 and 2,0 with one layer and so on. I ended up between 2,8 and 4,0): Welcome, dear visitor!
