ePhotozine published their full 135mm GM review. The conclusion:

The Sony FE 135mm f/1.8 G Master is indeed a very impressive lens. In terms of design, ergonomics and performance it cannot be faulted. It is expensive, and that is really the only downside to a lens that will produce the goods and offers the potential of a very long service life.

A superb choice for Sony FE mount full frame users and as such Highly Recommended.

The real one big issues with this lens is that it’s not in Stock anywhere :)

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

If you want to know which is the best “light” tripod ccheck out this new Dpreview test. they compared these four:

Gitzo 1545T (Amazon, BHphoto, Adorama).
Peak Design Carbon Fiber Travel Tripod (BHphoto, Adorama)
Manfrotto BeFree GT (Amazon, BHphoto, Adorama).
Surui N1204SK (Amazon, BHphoto, Adorama).

Engadget has tested the S1R and writes:

Is the S1R worth $3,700? If you had asked me this even a month or two ago, I would have said yes. However, Sony’s incredible new 61-megapixel A7R IV has put me in a tight spot here, based on the brief look we had. For $200 less, you get a lot more, including much higher resolution, phase-detect autofocus with incredible AI powered eye detection, and video features on par with the S1R.

Sony simply hasn’t given Panasonic an inch in performance, and has a proven track record with three previous A7R models. It’s a shame, because the S1R is a pretty incredible camera, but like Canon and Nikon, Panasonic is simply getting lapped by Sony in the mirrorless race.

The 240MP files from the A7rIV are surely going ot be stunning. Still, I wish Sony would implement an in-camera solution to elaborate the files…just like Panasonic does on their S1R! Please Sony work on that!
