Photons to Photos posted this DxOmark derived Sony A7rIV dynamic range measurement. As you can see the performance is about the same as on the previous A7rIII model.

Lenstip tested the new Sigma A 35 mm f/1.2 DG DN lens:

Sigma has entered the full frame mirrorless optics segment in a very decisive manner. Not only they presented a lens with unique parameters but they also took care of image quality, so the lens is able to offer you excellent shots across the frame. It is a really huge achievement because edges of the frame were notoriously difficult for even expensive, mirrorless constructions.

Still there is a price to be paid for that performance. Despite significant physical dimensions and a hefty weight you have to make do with huge vignetting and weak distortion correction. Perhaps the decision not to correct that aberration was crucial in order to ensure high resolution across the frame but, in our opinion, the slip-up with flares was avoidable; as it is, you can catch ghosting even if the source of bright light is far away from the frame corner. It’s a pity the constructors didn’t try harder.

Lately Sigma have got us used to outstanding constructions without any flaws. Does it mean we are entitled to criticize the 1.2/35 model? Not at all – at least as long as somebody presents a better lens with the same parameters. So far, the Sigma remains matchless and we should enjoy its unique parameters and quite good performance.

The Sony A7R IV Disassembly and Teardown

2020 is just around the corner, and if there is one thing we can be sure of, it’s that Sony probably isn’t going to be slowing down. While every iteration of the different A7 and a6000 camera lines launch with significant improvements over their predecessors, the most recent A7R took leaps and bounds in both capability and design progress. We’re at 61 megapixels on a full-frame now. The A7R IV brought us here, past the D850, the 5Ds, and even Fuji’s GFX 50 cameras. With that, it brings a 10fps continuous drive rate and all the top-notch AF and video capability we’ve come to expect from Sony. The body itself is just a little different on the outside. The grip is definitely a little beefier than before. The Nikon Z and Canon EOS R cameras’ design and ergonomics were very well received, and it makes sense for Sony to adopt as much of that “DSLR-feel” as they can. But, despite the subtle ergonomic improvements, the A7R IV is still a uniquely brick-like camera with all its rectangles and stepped edges. I don’t know about you, but at this point, I really don’t want them to change.

Chris and Jordan did choose the Sony A7rIV as the camera of the year. I own the camera and couldn’t agree more! It is the Jack of all trades and has served me well in the past months.

Sigma 24-70mm FE lens at BHphoto, Adorama, Calumet DE, FocusCamera. WexUK

Marc Alhadeff from SonyAlpha.blog reviewed the brand new Sigma 24-70mm f/2.8 FE lens and concludes:

–

The Sigma 24-70mm F2.8 DG DN Art (1200 euros) is an excellent standard zoom for the A7RIV.

Globally it is the best in its category for the A7RIV and the only one to resolve fully the 61Mpix sensor (only in the centre), its main weakness is the 24mm focal length where the Sony 24-70 F2.8 GM does consistently better

Pros

Excellent to outstanding centre sharpness on A7RIV between 35 and 70mm
Moderate price
Excellent smooth blurry background
Very Good Bokeh Balls with no artifacts and well rounded
Very Good build quality and ergonomics
Very good color rendition
Weather sealed
Short focusing distance
Fast and reliable and silent AF
Very Low CA except at 70mm (moderate)

Average

Visible distorsion and moderate vignetting but that should be corrected in a future Lightroom Lens profile (not worse than the Tamron or the Sony)
Resistance to flare is not a the level of what we have on Prime but Sony and Tamron have also same issue
Weight 830g (but lighter than the Sony 886g)
24mm sharpness less good than Sony but roughly similar to Tamron at 28mm
Corners sharpness only reaching very good levels max and good at 50mm

Cons

None at this price point

For A7III I would still recommend the Tamron 28-75mm F2.8 Di III RXD (900 euros) as the extra gain in performance of the Sony and Sigma won’t be noticeable most of the time

For the A7RIII and mostly for A7RIV:
if your main usage is around 24mm or are looking for very good consistency centre to corners around 50mm go with the Sony FE 24-70mm F2.8 GM
otherwise the Sigma offers superior performance mostly in centre (e.g. for portrait at 50 & 70mm) and for 40% less cost
