You are right, Khan!
I share your assumption: They are lacking the necessary equipment to check the physical dimensions precisely.

> I'd really like DPReview et al to be more flexible and compare the same way a potential buyer would compare, not an engineer.

As an engineer, I politely object to that. That's not how an...

> Equivalent FOV is what it's all about. Same F-stop, same exposure.

Misleading. 42.5mm/1.2 on ISO 200 gives same FOV, same DOF and same number of photons per image&time as 85mm/2.4 on ISO 800....

> The Oly is likely to compare quite well, even vs. FF (could even beat that old 35, at least wide open).

But the 35/2 on "FF" would be stopped down to 3.5 for a fair comparison. (Fair= same...

DA are the APS-C lenses that support full metering and AF. You can mount any of the older K-mount (Pentax bayonet) lenses directly, with more or less limited functionality (K, M, A, KAF, DFA, FA,...

Elaka, noise at same output size is almost independent from sensor resolution. If you look at it at 100%, the pic with more MP will be also larger, so the noise appears worse (per pixel noise vs....

I think you mean abomination, not abortion.
