mais51, that is true for now, but Italy like the rest of the EU has now standardised on the “German plug”—which fortunately has the same configuration for the main two pins as most European...

@donpjt, I see no point in comparing lenses of the same focal length when used with different formats — what matters for recording a given composition is lenses that cover the same field of view.....

@Bazzh: "bigger glass" is "faster" in that an aperture of larger diameter gathers more photons per second from the scene — this is exactly the same reason that a lower aperture ratio (at equal...

@donpjt That "better performance at equally high ISO speed" relies on using the same aperture ratio at twice the focal length (to get the same field of view), meaning in general a far bigger,...

Welsh make the usual assumption that the 36x24mm sensor is used with a lens of twice the effective aperture diameter, so about four times the effective aperture area—that’s what you get with the...

A quibble on the medium format sizes: they are all a bit smaller that the nominal “6cm by 6cm” and so on. The emulsion is 56mm wide, and the common formats are 42x56mm, 56x56mm, 56x70mm. That is,...

There are plenty of DSLR lenses out there — the new mounts and new lens design flexibility is naturally where the new lens design and production resources are going.
