CineD tested the Sony A7IV and concluded:

The Sony a7 IV shows overall very strong results in the lab test – really good dynamic range, 12.9 stops at SNR = 2! Rather good exposure latitude with 7 stops. But the rolling shutter falls a bit short unfortunately, it is on the high end at 26.8ms, also in comparison to the Panasonic LUMIX S1, S5, and S1H, the Canon EOS R5, and the Sony A1 and a7S III full-frame cameras.

ThePhoBlographer tested the Tamron 35-150mm FE lens:

Tamron absolutely deserves the Editor’s Choice award. The Tamron 35-150mm f2-2.8 Di III VXD is just an obvious choice here all around. The autofocus is fantastic, and that’s thanks to the fact that Sony owns part of Tamron. The image quality is unique enough while still also being more than satisfactory. There’s solid weather sealing, and Tamron even did the brave thing of putting a USB port on the lens. It feels good in the hands. It’s built solidly. It starts at f2 and ends at f2.8. But most importantly, it’s actually got a bunch of useful focal lengths. I can go from shooting a party or event to doing headshots with a single lens. I’ll get the best performance from it if I use a flash, and the exposure will be just as consistent. And honestly, I expect more professional photographers and passionate photographers to do just that. (TTL flash will win the day here; throw your L.E.D. lights away because they won’t do you justice.)

Most importantly, this single lens is almost convincing me to sell my Sony lenses. I own the Tamron 70-300mm and the 17-28mm f2.8. The Tamron 35-150mm f2-2.8 Di III VXD would give me everything I need. But of course, it comes at an extra cost of weight. However, the innovation here can indeed justify that.

The Tamron 35-150mm f2-2.8 Di III VXD wins our Editor’s Choice award and five out of five stars.

This is the best gear of the ear according to Dpreview:

Lenstip tested the new 70-200mm II lens and concluded:

Pros:

• solid, shapely, lightweight, and weather-sealed casing,
• sensational image quality in the frame centre,
• excellent image quality on the edge of the APS-C sensor,
• very good image quality on the edge of full frame,
• sensible correction of longitudinal chromatic aberration,
• negligible lateral chromatic aberration,
• lack of problems with spherical aberration,
• slight vignetting on the APS-C/DX sensor,
• very good coma correction,
• low astigmatism,
• nice out-of-focus areas for a zoom lens,
• silent, flash-quick, and accurate autofocus,
• very efficient image stabilization.

Cons:

• very weak performance against bright sources of light,
• noticeable vignetting on full frame.

If only the Sony FE 70-200 mm f/2.8 OSS II didn’t have that slip-up concerning the performance against bright light it would be really a perfect lens. There’s also the vignetting problem mentioned in cons but in such a construction it would be very difficult to avoid it (of course providing you want your instrument to have sensible physical dimensions and weight). Anyway, it’s hardly a tragedy, especially for mirrorless standards.

The Chinese site Xitek tested a whole bunch of 500mm mirror lenses on the Sony A7R. A couple of image samples can be seen here.

Digitalcameraworld tested the A7IV and concluded:

Don’t think of the A7 IV as Sony’s new ‘entry level’ full frame mirrorless camera. It’s both too powerful, too complex and, yes, too expensive for that. It’s more like a mini-A1 that’s terrifyingly good at everything but less than half the price. Stills photographers can revel in its 33MP resolution and incredible burst mode, while videographers get a camera that leaves the previous A7 III far behind.

Dpreview answered the question: “Should you upgrade? New Sony a7 IV vs a7 III”

Ultimately, then, it all comes down to money. The a7 IV is a better camera than the a7 III in just about every respect. Not just its performance but also in terms of everyday usability. If you’re in the market for a new E-mount camera and you plan to keep it for a couple of years, we believe the additional cost, spread out across those years, is worth it for a camera that’s just that bit nicer to work with, in addition to the specific feature upgrades it gets.

And this is Tonys take on the A7IV:

Sonyalpha.blog tested the 300mm A-mount lens on the Sony A1 and writes:

The Sony 300mm F2.8 G II SSM A-mount II (7500$) is a lens with an optical design of 2003 (Minolta) and it shows its age. Sharpness is just “good” at F2.8 on 42-50/61 Mpix cameras. On 24Mpix it still delivers very good results at F2.8 . Things get much better at F4 / F5.6 but you don’t buy a 7500$ lens to use only at F4/F5.6

On A1 /A7RIV is works perfectly with the LA-EA5 adaptor although limited to 8fps : the Af is very quick and efficient. However the adaptor does not allow AF in video but all other mode works in photography : Tracking, eye Af, animal eye AF…

What is striking with this lens is the butter smooth background blur , that I only find an equivalent in the Sony 400mm F2.8 GM OSS or the Sony 600mm F4 GM OSS

You get some excellent shots with a superb rendering with this kind of 300mm F2.8 lens. If Sony could release an E mount newly designed 300mm F2.8 GM between 6000-8000 euros it will be an ideal lens for sports/action photography but also for wildlife in low light , medium distance , for concerts, Portraits from a distance ….

The LA-EA5 by combining the motor you could find on the LA-EA4 and SSM compatibility of the LA-EA4 offers a great and efficient way to still use with very decent performances your A mount lenses (preferably on 24mpix)

If you don’t own the Sony 300mm F2.8 , I would not recommend to buy it new , but if you find it used for 2000 euros max and are ready to use it at 24Mpix max go for it

Waiting for a E mount GM version of this lens , lighter and capable to support 61Mpix , and 30fps, you had a preview of what could be the rendering of such a lens
