Besides ignoring the fact that our “detail vision” is only over about a 60° field of view, those measures are solely based on photoreceptor density of the retina, ignoring the resolution limits of...

It's rare to see the DPReview forums get excited about a camera that uses sensors smaller than the ones in smart phones. (I do see its possible industrial/lab role though.)

At a guess, color film will get squeezed out of most photography courses, in favor of a mix of B&W film (much easier for learning darkroom) and digital.

I agree that a computer like this should not be bundled with keyboard, mouse or display—typical customers almost certainly already have such peripherals, and/or want to make their own choices.
It’s...

Buon your own is always going to be cheaper, and Apple is just not in that market. The far more relevant comparison for the vast majority of computer buyers is “pre-built”, Apple vs Windows options.

The standard output based “JPEG at level 127” definitions are the only one ever used for the “ISO” setting on cameras, and indeed this is required by the industry association CIPA.

The relevant...

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...
