JT: “people always asking which 135mm ZA or ZF. Have a look at this: http://ift.tt/VlmtJs ”
Andrei: “I’m Andrei, a happy new owner of the A7s. As a long time reader, I wanted to share with you a slow motion S-Log 2 evening rain test and some first thoughts. http://ift.tt/Vlmsp8
Everything was shot at 120 fps 270p with ISO values over 3200. Light was less than ideal and I had a hard time getting perfect exposure because of the pouring rain. The lens is the Sony Zeiss Vario-Tessar T* FE 24-70mm F4 ZA OSS. Shot in S-Log 2, with modified profile, graded with Film Convert.
Observations:
- The lens is much better than some say. It’s just not as great as the 55mm 1.8 or 35mm 2.8, but OSS is very good and colour reproduction very nice. I’m not a pixel-peeper.
- The A7s held up well in the pouring rain, I only had an umbrella so lots of raindrops spilled on the camera and the lens.
- After some 2 hours of shooting, some blue hot pixels appeared which I noticed only afterwards. Scared, I thought of sending the camera back as it is still new, but then I read online that sony maps out “bad” pixels in software and fixes them on the fly. To force a remap just set the date to a month in advance and turn the camera off. It will take a picture before shutting off, after which they’re magically gone. You can set the date back afterwards. Hope the sensor is fine though…”

(SR3) 35mm f/1.4 G lens to be replaced soon?
According to one source Sony will launch a 35mm f/1.4 G lens replacement soon. And this is certainly a welcome news. This is one of the oldest “sony” lenses launched back in 2006. And now we have cheaper and better alternatives like the Sigma ART 35mm lens ($899 here at Amazon). I don’t know the price but I have been told the replacement will NOT be Zeiss branded.
