4K UHD is just over 8 MP.
8K UHD is just over 33 MP

The A7RII has more horizontal pixels than required for 8K UHD.

Normal A7RIV/A/V stills are 9.5K

Mark Galer is a Sony Ambassador because he is a good photographer (his channel is just a bonus for Sony). The folk over at Dpreview are less talented. Also, Galer clearly edited his pictures, the Dpreview pictures are SOOC.

You can get the full pictures from Dpreview. There is a lot of information in those files. I like my A7r4 pictures!

You only need 12mp for 4k, that is why the A7s3 is 12mp.

That is 3840x2160 pixels, that is 8.3 MP. However, the sensor is 2x3, and should be at least 3840x2560 = 9.8 MP.

Just being pedantic

Lol. I think I typed 2060 instead of 2160 into the calculator, oh well. Post fixed now.

There are some non-UHD 4K displays and video formats that actually have more than 4,000 horizontal pixels instead of just 3840 horizontal pixels. For example the old Apple 4K iMac had a 4096 x 2304 display.

I think you have to go to the FX6 to get 4096 pixel wide video capture.

In regards to Mark Galer optimizing his photos and video for 4K televisions, how are photos of other file sizes and formats handled by a 4K UHD TV? (Thinking of Mestari's comment about depriew's photos). As for the lenses, I know Mark Galer prefers to shoot with fast prime lenses, mainly G and GM glass, though he does like the non-G 85mm f1.8. We'd like to think that would make a difference in the quality of his photos and videos, but as pointed out, he has edited his photos and perhaps the dpreview photos are out-of-camera and unedited. I don't visit dpreview, so I don't know what they do these days. Most of my viewing is on my MacBook Pro and my M1 Mac Mini and computer monitors (non 4K). I do sometimes watch some YouTube reviews, like Mark Galer's on my Sony OLED 4K TV. For landscape photographers, I highly recommend Mads Peter Iversen's videos. He just some great videos of his photo shoots in the Italian Dolomites and Tuscany. Have spend vacations in Südtirol (actually just returned) these really spoke to me! I watched these on 4K TV. As he says, "Epic"!

The Dpreview pictures were taken with different lenses. I looked at pictures taken with the 24/2.8G and the 24-70/2.8GM II. And yes, the Dpreview pictures are clearly unedited. Take a look for yourself:

Smart TV's have built-in general purpose computers and can run various software. I really hate WebOS on my LG C1. There is a Media Player app included that can display images and videos, but it is barely functional. It can resize, zoom and scroll images. TV's can do all kinds of processing on their inputs too, but that can also be more or less avoided.

The XDR display on my Macbook Pro is close enough to 4K UHD.

Looking forward to some more detailed test results and reviews of this next R-model.
While it is probably listed at a too high price for many, it does help to bring prices of previous models down a bit.

Got a really nice deal on the A7 IV a few days ago. I was looking forward to getting that one in order to test IQ and AF differences vs. the A7R III.
And then yesterday, an excellent A7R IV offer passed by. Got that one as well, so I am really looking forward to getting a few hours to compare these three.
Actually, got both for less than the price of an A7R V .

Will see afterwards which will stay...
α7RIII α7IV 24-105G 70-200G 200-600G SY35/2.8 SY45/1.8 85/1.8 ~~~ RX10 IV ~~~ Nex-5 16-70/4 ~~~ α100 50/1.4 24-105

The A7rV has been shipping for a month or so. I'm wondering if any Dyxum members have one yet. I'd love to hear feedback.

For years, I've been using my a99ii for concerts, and have collected lenses (mostly primes) that make up my "ultimate kit" (IMHO of course). 100s of thousands of photos, so my fear has been that anything else will just feel "wrong".

I got my a7Rv about ten days ago, and have used it quite a bit for concert photography. A few small venues (dive bars) and one larger "proper" venue. Using the LA-EA5 adapter has given me the luxury of not (absolutely) needing any more lenses... but of course I got two native E-mount lenses: 20/1.8G and 50/1.2GM. I supplemented those with my old(er) Zeiss 24/2, Minolta 35/1.4G, and Sigma 35/1.4 Art.

Summary: Wow!

It can serve, for the most part, as an a99ii replacement. So my worst fears— that it would feel "wrong"— were not realized. The rear screen articulates differently than on the a99ii, which is probably the most glaring difference (I don't use the viewfinder). I can pretty much use all of my established techniques and get the results I want. So that's good.

But...

This camera is so much more. Low light performance? Better. AF? Better. IBIS? Better. Menu and customization? Better. The subject recognition and tracking have breathed new life into my A-mount lenses. I am still mid-learning curve on that but the results are incredible. High performance A-mount lenses (e.g. 24/2) lock on to subjects' eyes and stay there (the lock might get lost but it comes right back). The old screw drive lenses can nail focus near the edges and corners, even if, alas, tracking is not quite as good. It may be that some tweaking of the settings would help, I'll have to play with that.

With native lenses there is a big jump in performance. It's like I'm cheating. I can't recommend this camera enough, it's just that good.

Thanks for sharing ! One question I have: what made you go for the A7R V instead of an A7 IV (or A7R IV) ?

Thank you, Alec! Very positive feedback! Kind of what I expected. 50mm f1.2 GM, Wow! Don't think you could go wrong with that combo in concert venues! Happy that it is working so well for you, coming from the A99II.
I have the A99, but soon after purchasing that I started migrating to FE mount. A99 has great ergonomics and I love the articulating screen, but having used the A7III and A7rIIIa for a while now, it is hard for me to go back to the A99. I'm so accustomed to using back button focus and joy stick to move my AF point to the subject I want to track. AF with the A99 was good -- the A7III series is better and this A7rV moves AF to a whole new level, plus it has a true fully articulating screen. The flip screen on the A7iv is one reason I skipped it for the A7rIIIA since I shoot mostly in landscape orientation anyway and not so much in portrait/vertical. Also I seldom shoot video.
Thanks again for your report! OT, born in Alexandria (not Egypt) a place you are likely familiar with.
Regards,
Kelly

The rear screen. Over time I became dependent on the a77/a99/a99ii rear screen. The a7Siii? Quite tempting, but not enough Mpx (for me). The a7iv? Even more tempting.

When I saw the full specs for the a7Rv, in particular the way the screen articulated, I knew it was time to make the inevitable leap. I bought into the A-mount system a decade ago primarily out of lust for the 135 STF. The 50/1.2GM pushed me to E-mount in a similar way :)

I have it and have used it for a few days. Truly blown away at what it can do. The rumors and early reviewers were not lying or exaggerating. I have used an a1 quite a bit and thiers certain things the rv does better than the a1 even in the auto focus arena. Eye af has been extremely sticky for humans and for my dogs. Definately more so than the a1. Bravo Sony. A1 still beats the rv if you need absolutely instantaneous af on erratic moving objects or if you need 20 plus frames per second or more. But other than that the rv is level of not slightly ahead in a lot of areas.
