Opticallimits reviewed the new Sigma lens and concluded:

The Sigma 85mm f/1.4 DN DG ART didn’t receive too much attention out there, which is a bit strange in our book – it is among the best 85mm lenses that we have tested so far. It is plenty sharp at f/1.4 and only gets better when stopped down a little bit. The peak quality around f/4 is nothing short of outstanding. Image distortions are visible in RAW files but easily auto-corrected. The RAW vignetting is typical for a lens in this class – and, once again, there’s little to worry about with auto-correction. Lateral CAs are marginal. Conversely, axial CAs are clearly visible in critical scenes at f/1.4 and f/2. However, keep in mind that this isn’t unusual among ultra-fast lenses. The quality of the bokeh is good in the critical image background, with some nervousness in the foreground. Bokeh highlights are nicely rendered, but you’ll have to live with cat eyes near the edges. It’s a non-issue for photography, but videographers may not like that the lens exhibits pronounced focus breathing.

The build quality is exceptionally high and on the level of professional OEM lenses – other than the rather wobbly front cap. It’s also dust- and splash resistant. The Sigma lens is also surprisingly lightweight and compact for a lens of its class. The dedicated aperture ring offers a de-clicked mode, and you can customize the AF-lock button via the camera. The AF is both quite speedy and noiseless, with the usual caveat that this is heavily dependent on the camera as well.

Overall, the Sigma 85mm f/1.4 DN DG ART is a winner, and it deserves our highest praise – “Highly Recommended”.

New test shows Sony A7rV “monochrom” version would give 1 stop advantage and visible increased sharpness

Share

The new Leica M11 Monochrom camera uses exactly the same Sony A7rV sensor with stripped RGB filter (the sensor is listed on Sony’s sensor page). PetaPixel tested the M11 and the result is quite clear: the M11 gives 1 stop advantage and visible increased sharpness compared to the classic Bayer sensor!

I do believe Sony should make a Sony A7rV monochrome version for those reasons:

  • It would give us the option of getting the “ultimate” dynamic range and sharpness performance of those superb Sony sensors
  • It would be a camera without real competition (the Leica is way too expensive and limited)
  • It would not cannibalize any current Sony camera sales as this would find a completely different use.

What do you think?

FTP and Smartphone transfer issues with A7IV firmware 2.00

Share

Our reader Sylvain told me a about a FTP and Smartphone transfer issues with A7IV firmware 2.00

I’m a nobody enjoying my A7IV since it came out and I’ve been using ftp to transfer files from my camera to my NAS as part of my workflow. After upgrading to firmware 2.00 I did a FTP transfer to unload my card and most of my video files larger than 4 gb were corrupted. Being an embedded developer myself I further investigated and all pointed out to the A7IV firmware 2.00 corrupting the data that it sends to any FTP servers (even though the files on CFExpress Type B were OK).

After talking with Sony support today over the phone they confirmed they were able to reproduce the problem only with firmware 2.00 and he told me they would send the issue to Japan for a fix with no more inromation. I also saw someone in the Facebook “Sony A7IV Users” group that had the same issue as me (German guy). The agent that I talked to today said someone else yesterday opened a ticket for the same issue with FTP corrupting files.

The agent told me that sending files to smartphones was also impacted but I didn’t see that issue so far (can’t transfer XAVC S 4K/XAVC S HD anyway…). Probably sending a lot of files would eventually trigger the issue, I din’t try.

Oh, and if you want to reproduce the issue simply have a few files like video files larger than 16gb and transfer it to any ftp. My 29Gb easter video that I made over the weekend never made it through with every attempts that I tried. The file on the CFExpress type B is ok and readable

Hopefully Sony can fix this soon…
