Sigma 50/1.2 images


Recommended Posts

Posted (edited)

I was going to order it from B&H, but they’re closed until tomorrow.  If you could take some test shots side by side with your Lux it would be appreciated.  
 

The Sigma focuses 15cm closer than the Lux and 5cm further than the APO.  Right now I have both of them because I sometimes need the close focus ability of the APO.  If I could replace both of them with the Sigma I could take the funds from selling the other two to go on vacation and… use the Sigma to photograph everything.

First shots around the house, impressive results 

 

The Plus:

Feels noticeably lighter than the SL-50/1.4 

Quick AF, definitely faster than the SL-50/1.4

Punchy colors out of camera 

Biting sharp wide open at f1.2 

Minimum focus distance (0.4M) is noticeably closer 

Background out of focus area is very smooth and creamy 

 

The Minus:

Foreground is not so smooth 

Purple and green fringing easily visible 

One handed operation not comfortable, but this is more to do with the haptics of the SL3 than just the weight/bulk of the lens. I could atleast attempt it with this lens, with the SL-50/1.4 it wasn’t even an option

Interesting that you mention the purple and green fringing.  Even though the 50 Lux isn't an APO lens it exhibits very little purple and green fringing.  Looking forward to some more real use images.

Indeed, looks like the sigma doesn’t get the same level of in-body correction as the SL-50/1.4

Must be a fair bit as it rarely shows any CA 

how do we know how much is not there because of optics and how much is corrected? maybe the optics just show less CA than some other lenses. (I don't know)

Having a rather large collection of lenses, in my experience, it’s mostly the APO lenses that are mostly well corrected. I say mostly because even the APO50 and APO90 show traces of fringing. The M-50/1.4 ASPH is the exception as it doesn’t have an APO designation but is well corrected. Almost all other lenses show purple/red/green fringing, so until and unless Leica found some way of correcting the SL-50/1.4 through special glass and optical construction, the assumption is that it’s being corrected in-body. I care about the end result, so it’s ok for me. 

Since the sigma does show fringing, the assumption again is that it doesn’t get the same level of in-body correction. Maybe it behaves better on L-amount sigma and Panasonic bodies?
