ULTIMATE Image Quality test: Sony a1 & a7R IV vs Canon R5 & Nikon Z7 II 

Hello Tony & Chealsea, thanks for this great review. That's a lot of work. In the video I see you can use Lightroom with the alpha 1's pictures. Does it mean that Lightroom is updated to support the alpha 1's RAW files? My Lightroom does not support the alpha 1's RAW files and it slows my workflow a lot. Thanks

Tony, why do you keep saying, "The A1 is a high speed camera and gives you both high resolution AND high speed...", (paraphrased slightly) - and THEN saying at the end that the Canon R5 won when clearly it can't compete speedwise (...and it has h'orrendous rolling shutter)? This is the second time? (Beyond the fact that you left out the REST of the advantages to the A1 over the R5)! Highly annoying... (and erroneous that your conclusion would be summarized as a win for R5, when it can't even compete in the same league when looking at the entirety of its offerings). The Alpha 1 was the ONLY camera that could give you a clean image in that room, yet you say the R5 didn't do that bad? The A1 also preserved more of the highlights, and the shadow test fractional and you (of course) gave it to the R5? Z5 comparison was with totally incompatible ISOs! This is getting ridiculous? Then you say R5 was best all around? Laughable? --- Tony: "The Alpha 1 gives you all the megapixels AND gives you the high speed." The comparison should have just ended with that. It was over at that point because the R5 (and all the others cannot do that, and probably not for a few years!) - The other 14 minutes are a waste... Especially with the false conclusion at the end! __ Also, there are some problems with your test procedures, but nobody's perfect. But anyway, sad to see you have it out for Sony to this degree... What did they do to you? (It appears Tony isn't a PPA member? Why is it advocated?)

@@cogmission1 Have you used an R5? The rolling shutter is really no big deal and isn't 'horrendous' as you claim. I shoot BIF mainly and rarely encounter it and can shoot 20fps full raw with no problem. I have to pan really quickly against a background containing lots of vertical uprights to induce it.

Except from that BIG MISTSKE you mentioned above, you didn't even show a head to head shot of r5 and a1 in terms of details! Also lens sharpness has a major role in detail comparison, again using an old zoom lens by Sony which in term of sharpness is nothing comparable to recent lenses from all manufacturers including Sony itself! Why not using prime lenses? And final note; you skipped talking about Sony A1's awesome flash sync speed of 1/400s at 2:42 jumping from a7r4 to pixel-shift term and then showing the pixel-shift result of A1! I'm not going hard on you Tony but just mentioned these to tell you we understand that! But I'm OK with your recent take on Sony's products as remind me of your past attitude to canon products like original R which lead them to make this big leap to the r5....so yes keep going to get harsh on Sony to push them to get better and better! Thank you

So which one does better in low light for both photo & Video? I Love to know!

probably for the sharpness test. Not really for the others.

Exactly! Lenses will have much more of an impact than the camera will.

The lens information is visible in the Exif details in the Lightroom screen

We all know they used a bunch of 1.4 primes

Well, the af test is way more relevant. Differences in image quality are minuscule and those cameras will all be indistinguishable in the real world. If a camera can't keep the subject in focus however, that's a big deal and means lost shots.

@@youknowwho9247 For you. My af needs are fairly easily satisfied. Have had no problems from film days through my 12 af point D90 to me D610 and D500 today. Since I want to stay with Nikon, the presence of banding in pushed shadows is a concern. I will have to look at that more closely.

@@lsaideOK don't worry about banding. Only in extreme situations. And if you are an old timer like me, you will not have to push your shadows. My Z6 even doesn't have banding issues.

@@lsaideOK I wonder if you've actually tested any of the Nikon mirrorless options. Because I have, and they're all far, far worse than the D500 in terms of af. Also, why would anyone upgrade to mirrorless from a top end DSLR, if not for edge to edge focusing and eye af? What else does a mirrorless camera do that your DSLR doesn't?

@@youknowwho9247 silent shooting ! Which for my subjects is a real bonus. But for gods sake Nikon SORT OUT THE LOUSY AF

I am as well. This "review" (if you can call it that), leaves out a TON of other advantages to the Alpha 1: 1. Full size HDMI 2. 2x faster USB at 10Gb/s! 3. Ethernet port 4. Micro USB control port 5. Digital hot shoe (Cordless microphone!) 6. Simultaneous recording (to even different media types). 7. 6x Much longer 8k recording (infinite when using dummy battery) 8. Better heat dissipation design (on TOP of more compact body size) 9. Blazingly fast cool down vs. Unusable R5 after first heat warning (basically). 10. Negligible rolling shutter vs. Extreme R5 Jello. 11.1/400s master sync speed vs. 1/250 for R5. 12. 1/32000 to 30sec. shutter vs. 1/8000 to 30sec. for R5. The list goes on... (except when reviewed by the Northrups)

Yessss sir! Please make it...so we finally can see a definitive review of this camera by someone we can always trust!👍

Dustin, looking forward to your review!

@@cogmission1 Dan Waston shows that in sun light the R5 lasted a little longer than the Sony in overheating . But yes the Sony cools down quicker and has a better heat override! If you think that's good great . I don't see any rolling shutter . But that's what you think then fine . All the other stuff yes your right but will make not difference to the way I shoot photos any I can hold the R5 nicely in my hand . Oh you can get a battery grip with a Ethernet port and better WiFi and it still would be cheaper

@@Tainted-Soul Re: In Sun overheating, it **may** be true but I'm HIGHLY suspicious because out of like 10 reviewers, he's the ONLY ONE who's gotten that result? Potato Jet put it in an OVEN ffs! :-). (

And the Nikon costs the least of the bunch too, it's closer in price to an r6 than an r5

@@detectivejonesw Keeping my old camera for another year, or several years, is even cheaper! (Or purchasing a used one as it’s been around the longest and many have been sold.)

@@bobsykes it certainly is cheaper, free in fact

@@bobsykes AMEN to that. I feel no desire to "upgrade" to the latest and "greatest." I'm still doing fine with my Nikon D500 and I also still use a Panasonic GH4 for video. Very pleased with both and no customers have ever complained. When Panasonic releases the GH6 - I'll weigh the options on whether to buy that - but most likely that's when I make my move on the GH5 - as it will go down in price considerably. Also - I tend to take a lot of pics with the GH4 (I do nature mostly) and the pics out of that are just fine.

@@bobsykes I just bought a used Z6 for under $700. Excellent camera! So don't hang on to those old SLRs!

And how is it going with the Z7II ?

Your first questions about lenses used for IS testing particularly interests me too.

@@tkermi yeah... the Canon approach claims that having IBIS + lens IS should give you even longer exposure times without camera shake induced motion blur. Also... how many shots did you take for the test at each exposure-compensation per camera. Not saying that the Northrups don't know how to do a proper test, but I'm a physicist, I miss those details... maybe even standard deviations or boxplots. Sometimes I wish I had the time to go and engage in such tests for a week. I'd probably go way overboard but I like my quantitative analyses.

@@andreasbrand3191 I know, I would like to make that kind of intensive testing too 😂. Well I actually now have the time but not the health/energy - limited from doing that nevertheless. I also like to keep myself up to speed of the recent camera tech. Can't wait to see what EOS R1 brings.

Agree

and I bet you don't find any banding either do you? Banding is fake news.

@@gosman949 I have the Z7ii myself and have just underexposed 5 stops and brightened 5 stops in Lightroom. I don't have banding. But I don't know how to get the test right. Maybe I did something wrong! I would be interested how Tony did it!

@@gosman949 Banding isnt fake but its overrated

@@gosman949 not fake news, but very uncommon.

Those lenses are Epic, I have all 3!

Glad you liked it!

This is exclusively about image quality i think

Yes, I did not get it. My 1DX2 has excellent DR. The large pixels provide some benefits in IQ.

He was probably talking about the the original 1DX. But even this camera has similar DR to other Canon FF cameras of its time.

Exactly!

And color science

hilarious

R5 is better

@@ryanb8736 Ha!

@@Joseph-iu6ip color science doesn't apply to raw, heck even to jpgs. who shoots SOOC any more.

If it gives you joy, I'd say it is for you regardless if you get good photos or not 🙂

Let me correct you: If you can't take a good photo with a high-end fullframe camera from 2012, photography is not for you.

@@dtibor5903 I still shoot wedding with my a99 ii. Not the best camera but does the job.

What made you decide on the z7ii?

Artifact of screwed up Pixel Shifting

Dont expect that .. There intent is to clearly pramote a1 through this video n subdue Z7ii.

Good eye! I definitely just selected the wrong photo for the screencast but the actual result doesn't change... no real difference in captured detail between any of the cameras.

The Z camera did just fine in this test.

因为放大的比其他机器多，应该缩小到一样大对比，像素越多越清晰，这是毋庸置疑的。
