Sony 24mm f/1.4 GM review at Photographyblog: “outstanding wide-angle prime lens “

Photographyblog posted the full review of the new Sony 24mm f/1.4 GM lens (preorder at Bhphoto. Adorama. Amazon. Calumet Germany. WexUK.):

The Sony FE 24mm f/1.4 GM is an outstanding wide-angle prime lens with a very fast maximum aperture, although the high asking price is certainly reflective of the performance and image quality on offer.
This relatively compact, lightweight optic delivers excellent sharpness in both the centre and edges of the frame almost throughout its aperture range, even performing well wide-open.
The near-circular 11-blade aperture creates some lovely bokeh effects, despite the wide-angle nature of the lens, making it suitable for everything from landscapes to portraits, as shown in our Sample Image gallery.
Coupled with a high-resolution camera like the A7R III that we tested it with, it’s capable of producing incredibly detailed, very sharp images, with Sony’s excellent Eye AF function seamlessly tracking the subject.
The Sony FE 24mm f/1.4 GM delivered fast, near-silent and reliable auto-focusing on the A7R III camera, intuitive manual focusing and a high level of build quality, plus it’s usefully weather-tight too.
If you really love the 24mm focal length, we’d heartily recommend the Sony FE 24mm f/1.4 GM – you certainly won’t be disappointed by the image quality that it can deliver.

And here is the hands-on by Photogearnews:

NIkon Z7 has stripe issues and lower Dynamic Range than the Sony A7rIII

Photonstophotos published the Nikon Z7 Dynamic Range tests results and I am surprised to see how much better than Sony A7rIII performances against the Nikon. And Dpreview just found what’s causing this “Gap” with the Sony:

  • In principle, dynamic range is comparable to that of the D850: one of the best performances we’ve seen.
  • However, striping and banding (caused by the addition of on-sensor PDAF) means the usable dynamic range is reduced.

Here is the banding compared to the Sony:

Dpreview writes:

As you’ll see in some of the images above, a banding pattern can appear if you try to pull darker tones into the image. The frequency of these stripes leads us to believe it’s a result of the way the phase-detection rows of pixels are incorporated into the image (something supported by our collaboration with Bill Claff).
In addition to the banding in shadows, we’ve also occasionally seen the same pattern in images with flare caused by a bright light source

I don’t think this is something Nikon can fix via firmware update.

If the Z7 would be a Sony camera I would imaging the usual troll saying that Sony has never been a serious camera company and they can only do Playstations :)

First 400mm GM unboxing video and tests!

400mm f/2.8 FE preorder at BHphoto, Adorama, Amazon, FocusCamera. In EU at Calumet.de and ParkCamera.

Marc Alhadeff got his new Sony 400mm f/2.8 GM lens and posted a full review. The conclusion:

If you are a Sports or a wildlife photographer, the Sony 400mm F2.8 GM OSS is your dream lens.It delivers outstanding images and is highly versatile thanks to the 2 TC that can transform it into

  • 560mm F4
  • 800mm F5.6

Verdict

  • Outstanding sharpness at all aperture from centre to corners
  • No loss of speed or sharpness when used with TC1.4 TC2.0
  • Extremely fast and efficient AF when coupled with A9. Very good otherwise
  • Capable of capture very high speed animals : 1/32000 sec possible with A9
  • Very good blurry background most of the times and 3D effect
  • Lightweight for this kind of objective 2.8kg
  • Very well balanced , can be used handled for 30-60min without issue
  • Outstanding build quality
  • Very good usability : all preset function, special function ring to set a distance or enter in crop mode
  • Drop in CPL filter possible
  • Light but solid transport case including space for the 2 TC

Of course

  • It is pricey : 12000 Euros
  • You need to use high shutter speed to avoid blur
  • best used with monopod or Tripod with Gimbal

Points of attention

  • Lens hood fixation system : you need to attach it to the lens by screwing a knob. The Lens hood is in carbon fibre and can be sensitive to shock  (980 euros to replace the lens hood  if you break it!)
  • Sometimes not perfect blur with noisy background
