The Coming Oly EM1+12-40mm f2.8 MFT
#18
Quote:While you are correct with regard to the FF equivalence, I don't think it does this lens justice.
Why not?

Quote:As I see it, the main purpose of fast standard zoom lenses is not minimal DOF, but versatitiy with respect to both focal lengths and lighting situations (indoor photography without flash etc).
And as being equivalent to a 24-80mm f5.6, in what way is it more versatile to a 24-70mm f4 on FF (or 24-80mm f5.6 on FF, if such a thing would exist), a 17-55mm f2.8 on APS-C?

Quote:With f/2.8 and a usable ISO of 3200 (maybe even 6400 in a pinch) on the OM-D cameras, this lens offers just that.
That is the same thing as saying with f5.6 and a usable ISO <setting> of 12800 on the D600/6D cameras... 

Quote:Another thing to be noted is that this is Olympus' first standard zoom that you can actually stop down without being limited by diffraction. I expect to see some very good performance at 40mm f/5.6 with this lens. 
It is a nice lens on the platform, as I said. But not so nice when you look cross platform. Anyway, I am pretty sure that at 16mp on the MFT sensor, you will already have loss of resolution due to diffraction at f5.6. Just like you have loss of resolution due to diffraction on FF at f11 (and on APS-C at f8).

Quote:As far as competiveness across platforms is concerned, I don't think that MFT ever will be (nor wants to be) competitive with FF cameras in terms of high ISO performance & shallow DOF. It's just a matter of what you consider "good enough" in those areas and how you value other aspects of the systems (e.g. size, weight, and whatnot).
As I said, nice lens on MFT. But it is not a lot smaller than "f4" lenses on APS-C, is it?
