Working on Sony FE 24-105mm f/4 G OSS

See my Sony wish list and get Sony A7R III at B&H Photo.

I shot some material (aperture series and others) this morning with the new about $1298 Sony FE 24-105mm f/4 G OSS at 24mm, 35mm, 50mm, 70mm, 105mm, on the Sony A7R III.

While I did shoot this morning, the day was just too nice to not put in a tough early season workout so that I can place high this year and do 13 double centuries. That took some time and kind of wiped me out for about 2 hours after, which is to be expected.

The 24mm zoom setting will be shown versus the Zeiss Batis 25mm f/2 Distagon. The 35mm zoom setting will be shown versus the Zeiss Loxia 35mm f/2 Biogon. I forgot to shoot the Loxia 85mm f/2.4 against it, but I might do that, depending on what I see from today’s results.

I’m not fan of consumer style gross extensions of lens length when zooming from 24mm to 105mm, but that is a matter that I will comment up on my review, and why.

I am definitely not of fan of enforced distortion correction, which is the case with the 24-105. This is a serious usability problem for composition because the camera grays-out the Distortion Comp setting, so when composing the distortion is being corrected, leading to framing errors if processed without distortion compensation (which Adobe Camera Raw now allows). Since the 24-105 has extreme barrel distortion at 24mm, maybe one has to correct in anyway, but this is not true throughout the range.

I *am* a big fan of the button on the lens (next to the “G”) that is an outstanding way to program Eye AF initiation and a good example of why buttons are useful.

I am very annoyed that the AF w/shutter = Off setting is IGNORED when using pixel shift mode (see Tip #3 of Autofocus Configuration for Sony A7R II and Siblings: Buttons and Eye AF). This is a bug since it is not ignored with pixel shift off. Or maybe Sony will say it is “by design”, but I can think of no logical reason that this should be so, if anything, the reverse. This tripped me up over and over today. So many wasted chimping button presses to work around it. I almost always want it off, but now Sony forces me to use the switch on the lens, a troublesome requirement since some lenses have it and some do not.

Nick M writes:

I can confirm that my camera with firmware 1.0 behaves in the SAME way as yours. The setting for AF w/Shutter is greyed out and set to ON. Why on earth would this be? Back button focus does work (which is what fooled me previously), but will be overridden by the shutter button as soon as pressed - what a nonsense. For me this means always switching to manual focus (with C3) which is not so bad I guess given the nature of the mode.

DIGLLOYD: what a hassle. I don’t know anyone at Sony to notify to get this bug fixed.
