Lensrentals about the new Sony 135mm GM lens: “sharpest lens we have ever tested”

Share

Lensrentals tested the MTF of the new Sony 135mm GM lens:

These results are insanely good. At 100 lp/mm the Sony 135mm f/1.8 GM has a higher MTF than most excellent primes do at 50 lp / mm. If you don’t speak MTF, basically that means this lens can resolve fine details that would be a blur on excellent lenses. This is the sharpest lens we’ve tested. Period.

And below a new test by Miguel Quiles and an interesting comparison with the Sigma 135mm ART by Manny Ortiz:

 

Preorders:
Sony 135mm GM at Amazon, BHphoto, Adorama and FocusCamera. EU at ParkCameras, WexUK and Calumet DE.
Sigma 135mm f/1.8 at BHphoto, FocusCamera, Amazon and Adorama.

(SR3) First rumor about a new RX vlogging camera launch in late March

Share

I just got this from a reliable source. He heard about a new Sony RX camera launch in late March. But this isn’t going to be the RX0II (which is coming too). This will be a new fixed lens camera with optical zoom. And he got this early info:

– compact camera with optical zoom
-Dual slot
-Lots of video features including, brand new video codec, colour grading video
-Custom function key button set up (e.g different set up for photo and video
– WiFi options (2.4 / 5 GHz)
– made for Vloggers

I think a dual slot excludes the RX100. So this is likely to be a new RX10 or a very new kind of RX camera.

Laser Damage on Sony A7SII – frying a very expensive sensor

Share

Andy Boyd:

Hot tip: Don’t record laser tattoo removal on…anything. You can see with each pulse the sensor shows new damage. The repair cost was about as much as a new camera so try to avoid this. Club lasers can do this too but we’d never seen the reflection of a laser beam do damage, only when the beam itself hits the sensor.
