Optyczne has analysed the R6 II

[AlanF]

Optyczne.pl, the mother site of lenstip, is one of my favourite sites as it does rigorous measurements on bodies and sensors, AF etc. The R6 II has scored very highly on AF accuracy, and its sensor resolution is good https://www.optyczne.pl/index.html?test=aparat&test_ap=485 It appears to have no low pass filter in the vertical direction and a weakened one in the horizontal. The result is that its 24 Mpx sensor outresolves the 30 Mpx 5DIV, which has very strong low-pass filters, but at the expense of some Moire. I know from experience that the 5DIV's resolution suffers to get rid of any Moire. The R5 also asymmetric low-pass filtering but in tens of thousands of my bird photos I have never seen any Moire in the feathers.

This site lost their credibility few years back once they told they wont test RF lenses.

You don’t lose credibility for testing camera bodies because you don’t test lenses. They actually used RF lenses in their resolution and AF tests. One thing about the site is that the comments are the rudest I’ve ever in seen camera forums.

True, but you loose credibility when you test all the lenses except ones produced by the market leader.

It's annoying they don't as when they do test, they do it well. Do you know the reason why?

 

[Hubert Multana]

Chief editor is claiming that there is no existing camera that would allow them to test those lenses correctly.

…The result is that its 24 Mpx sensor outresolves the 30 Mpx 5DIV, which has very strong low-pass filters, but at the expense of some Moire.

That fits to the results of some German foto magazines, that the R6 II sensor performance outresolves a lot of higher MP competitors, Even the R3 BSI, and only the R5 is better.

I know from experience that the 5DIV's resolution suffers to get rid of any Moire

And from my experience with the 5D4 loss of detail I can second that as well.

Very interesting information.

Very interesting - Q: do you know if the EOS R has the same LP filter set-up as the 5D IV, ie along with the same sensor?

It looks from the optyczne measurements they are the same.

 

[Jethro]

Thank you. As I plan for (possibly) updating from the EOS R, that make the options clearer. The R6 II at 24MP was already more appealing than the R6, but objective evidence that it also outresolves the 5D IV / EOS R makes it more appealing. I don't need FPS speed, but IBIS would be great.

I'm therefore also intrigued as to whether the rumoured R8 has the same (or a version of) the R6 II's 24MP sensor, in which case it'll get down to the list of features (including form factor and inclusion or otherwise of IBIS).

It seems like Canon has prevented them from making the tests. At least if we are to believe a comment on their website:

It's best to call Canon (I mean the headquarters in Japan, of course) and ask when they will release a can that would be suitable for testing their RF lenses in Poland. It seems to me that they need to explain the situation, describe the problem with testing lenses on the most serious Polish industry portal, and let them do something about it, maybe just build a special camera only for testing, because it can't be like now there must be such a backlog of tests.

Well, unless Canon wants to hide something, e.g. some specific defects of their lenses and that's why they haven't made a camera so far that would allow them to test their lenses - there may be something to it, such a theory makes sense in my opinion, they just don't want to spoil themselves interest and lose market share in Poland and Europe, which is why they are scheming and there are only cameras on the market that are not suitable for glass testing.

Something needs to be done about it, as they removed the most famous mailbox in the country, a living advertisement of Poczta Polska, we immediately acted at the source and the box returned to its place, continuing to serve the masses of photographers - now something needs to be done and as I say, it's best to attack Canon and either call or write an e-mail or several e-mails. If we all start writing to them, there is a chance that not everything will fall into spam, they will read and maybe change their policy towards cameras, and there will be at least one on the market where you can test the lenses.

It may be because of $$$ reasons. Send them a rental and hope they send it back for them to test it?

That reads like conspiracy drivel. What is preventing e.g. an R5 from ‘testing’ lenses?

 

[gruhl28]

They’re testing camera bodies, but there isn’t a camera they can use to test lenses? I don’t understand.

 

[Hubert Multana]

They receive cameras from Canon Poland for tests, it's just their will not to test lenses. For biggest portal in the country it is not a problem to receive anything for tests, or even buy it if needed - or rent it if absolutely necesary.

Everybody sees that nonsense, besideds the portal owners.

It's frankly crazy their not testing RF lenses.

Time will tell if market forces will change their mind. ;-)

I'm less sure, now.
After having read Brian's TDP EOS R review again, I proceded today to a comparison between R and 5 D4. Brian always repeted that he didn't understand why the R , compared to the D IV, lacked some sharpness.
To resume what I did:
-Same heavy tripod on concrete
_My best lens (Apo Macro Elmarit), infinity setting
-Mirror up, timer shutter release
-High shutter speed
The 5 DIV was always visibly sharper (not a huge difference, but couldn't be overlooked when pixel peeping).
Filter? Protection glass?

 

[davidespinosa]

Do they need an R1-class camera for adequate lens testing ?
100 MP or something ?
