- Sony unexpectedly released the Sony Alpha a7R Mark IV just this past week. I was fortunate to have been invited by Sony to come to New York to get some hands on time with the camera.
This is my first impression.

Seems like a terrific camera; however, for my current needs, I am keeping my A7R III as my main camera and A7R II as my backup. Thank you for doing this.
Awesome!! Eagerly waiting for your detailed review for wildlife.
Fantastic, reasonable and balanced review. I’ve watched half a dozen reviews of the Sony 7r IV and I thought your review was the best. Thank you.
Thank you Vic. Hope to be publishing a lot more.
ReCompose podcast isn't the same since you left Juan....It was sooo abrupt. . Glad I found you here....
Thanks for the kind words. I hope to be able to produce more varied content here. Stay tuned.
Nice job Juan!
Thanks David
I’m sold but I’m going to wait when the A7 R V comes out.
I looked at the A7R4 as it came out before the A9II. I thought about all those mega pixels but in the end went for the a9 for its faster focus speed and low light capabilities .
Understandable, everyone has different needs and requirements. Glad you found the camera that meets yours.
Jaun, You are as impressive on the small screen as you are in person. I continue to learn new things from you every time I see you. Hope you will do a similar review when the Canon 5D Mark IV is introduced.
Thank you Bob.
The 5D mark IV ????
@@markrigg6623 Meant the %D Mark V
@@BobPliskin I figured. They might update the Dsr before the the mk IV.
I think hell might freeze over before Canon gets around to updating the 5D :) Took them 5 years to go from the 5DIII to the 5DIV
Hi Juan, thank you for putting in the time to make this very good video. Currently I am shooting on the A9 as it fits most of my needs (Wedding/Portraiture/Sports and Wildlife). But I have found that I would like more resolution at certain times. So I am thinking about adding either the A7R3 or the A7R4. I get the feeling that you feel there is a pretty good improvement in autofocus with the A7R4 over the A7R3?
Thanks for the kind words. There is HUGE improvement on AF in the a7RIV over the a7RIII. An incredible improvement for sure.
new Nikon a6 is announced so goodby sony!!
Depends on how the Autofocus will perform. Benchmark for me is the Sony A9. If the performance is close, especially on tracking, then I am into it. Otherwise better no. Pixel Shift I don't need, this function anyway not useable as in reality we mostly have even small movements in the scene.
Doesnt have the A F performance of the A9 but is still better than Riii. Has much better image quality however. So there's a trade off which ever one you choose. Maybe wait for A9 ii.
@@markrigg6623 Hmmm...not sure. The beauty of the Sony A7R4 would be the possibility to crop making this camera quite attractive for Wildlife.
@@Stefan1968ful Agreed. I'll be getting one for just that.
I agree with @Stefan1968ful
Actually, if you compare the A7RIV with the A7III you get 943mm instead of 600mm. You have to divide the pixel size by one and other. So A7RIV = 3.76µm A7III = 5.91µm ---> 5.91/3.76=1.57x and 600x1.57=943mm. Pick any sensor aps-c, full frame, 1" doesn't matter, just divide the pixel size and you get the 'real' cropfactor based on RESOLUTION. A general crop factor of 1.5x is based on sensor SIZE.
Awesome review. Just curies about the AF compare to a73. Most of the viewers compare r4 to r3, but beating r3 is a easy job. What about a73~~~
I am not sure what you mean, from my experience the AF on the r3 is better than the one on the a73.
@@JuanPons what!!?? a7iii AF is better than a7Riii for sure.
@@oldboysadventures9457 You are right, I got the models mixed up in my head. I have not compared the r4 with the 7III, but considering the AF on the r4 is not that significantly better then the r3 I would expect the 7III to outperform the r4. Apologies for the confusion.
How is the A7R4 with the 200600? I'm hearing mixed reviews...some saying 100400 is a better combo? Very frustrating as I just picked up 200600 in anticipation of the A7R4. Thanks
Furthermore do we need 600mm when you can crop in from 400mm??
I think the 200-600 performs about the same as the 100-400 with the a7r IV. Sure you can crop from 400 to reach the equivalent field of view as a 600, but you will lose quite a few pixels.
@@JuanPons I am hearing the 100400 out resolves the 200600 if you crop in tight, you can see this
If you look at my video where I compare the two you can see that in certain situations one can out resolve the the and vice versa. In any case the difference is very Very small, So I would go with the focal length that best suits your shooting style and don’t obsess about which lens outresolves the other in pixel peeping comparisons. Both lenses can produce amazing images, and the photographers skill level is what matters most in this case, not which lens is a tiny bit sharper than the next. I have been shooting with the a7R IV and the 200-600 for a week in Grand Tetons and Yellowstone testing out the set up and I can tell you without a doubt this is an amazing combination, Make sure to check out my next video that should be out Monday where I show the images I made. My advice, focus more on your skill and focus less on the minute details of the gear. Hope that helps.
@@JuanPons I have both lenses on A7RIV... and with that body 100400 out resolves 200600
A7RIV has a significantly better EVF than both A7r3 and A9
Yep it sure does.
No one mentions the fact that its 10fps is only in 12 bit raw and hence its dynamic range will be compromised compared to the 15 stops that Sony quote.
I mention the fps in the first 2 minutes of the video. DR is not ALL about bit depth. Until we have good tools to process the raw files we won't know how much DR there really is.
@@JuanPons No dynamic range isn't all about bit depth. The design of the sensor provides it's base but on all the previous models lower bit depth then detracted from that. You also get some weird edge artifacts with 12 bit in some high contrast situations on all previous versions. I'd love it if this was found not to be the case on the new model however!!!
@@JuanPons I didnt say you failed to mention the 10 fps- just that you didnt qualify its bit depth at that rate. Thanks for the reply.
This form "factor" buisiness just sounds silly. It has some specific uses but people just repeat it like they are parrots most of the time. Makes me laugh. A bit like color "science" and "I P".
