Not really, especially when you factor the actual transmission or t-stop. It will always vary this amount one way or another in practice. For example, there are f1.4 lenses are more or less ...

f9 is just over a stop compared to f5.6, so it's not a huge deal once it has good IS. It being white, but not an L lens, makes me think it will be marketed as a DO lens.

In my experience, there's about a stop difference in noise eg. my R10 at ISO 6400 is as noisy as my R6 at ISO 12800. The same from what is seen in RAW studio tests. Maths wise, this sort of lines ...

If the lens is sharp enough, yes. Noise would be about a stop worse on APS-C on average, so the difference isn't that massive anymore, especially with AI denoising.

R7 will still have more resolution compared to the cropped 60mp R5, as 32.5mp x 1.6 squared = 82mp FF sensor.

I was about to say myself. None of this addresses what I've said. There used to be another accompliance in the AF fumbler crusade a while back, who was mixing up AF issues with inherent softness of ...

This was already explained to you, especially when the AF point is larger than the subject itself. You have a long history of bringing up "AF issues" that are not really substantiated by anyone ...

I think its purely just a limitation of the current AF tech on RF cameras, rather than an actual issue. In my experience, every RF camera I've used - R, R5, R6 and R10, has nearly a 99% hit rate on ...

He'll complain anyway, even if it doesn't match reality Think about it, he complains about NATIVE lenses that work perfectly fine already!

Not really. Even with the crop, you still get decent results that would still give large prints.

DPreview's main fumbler is back, confusing AF limitations (as in not being psychic) with AF problems.

EF 17-40mm f4L

+1 on the 10-18mm. I did the same when I recently got my R10.

Can you post an example?

@G Dickson - Sigma's 120-300 is cheaper because the optical design isn't as sharp. Canon's 100-300 is going to be sharper than the 300mm f2.8L mk2, which is an extremely sharp prime lens in its own...
