Advertisement Posted September 2, 2008 Posted September 2, 2008 Hi rosuna, Take a look here New CMOS technologies. I'm sure you'll find what you were looking for!
like_no_other Posted September 2, 2008 Share #22 Posted September 2, 2008 I understand so far that diffraction is not limiting maximum resolution of the lens-sensor system, even not with 50mpix sensors in FF format. Diffraction depends only on the opening/gap where it happens, here the aperture opening. Apertures smaller than f11, better f16 or so, on nowadays APS sensor format can degrade sharpness visibly in pratical photography. One or two stops stopped down, even good lenses deliver maximum sharpness, let's say at f4. Now my question. Why should 30 or 50mpix sensors shift the f11/f16 border close to f4 or an even smaller value if the lens itself is good enough to resolve 30 or 50 mpix (at f4)?

ho_co Posted September 2, 2008 Share #23 Posted September 2, 2008 l_n_o-- What we've learned in analog photography is partially out of date with the advent of digital. See for example the article at Luminous landscape. Issues still open, but it's pragmatically clear that diffraction today occurs also at the sensor level.

like_no_other Posted September 2, 2008 Share #24 Posted September 2, 2008 Then let's hope that we will not get any interference patterns in two or three years when the imaginary gaps on the sensor will be a few hundreds nanometers. lol PS what does l_n_o-- mean?

farnz Posted September 2, 2008 Share #25 Posted September 2, 2008 ... what does l_n_o-- mean? l_n_o = abbreviation for like_no_other? Pete. Link to post Share on other sites More sharing options...
markowich Posted September 3, 2008 Share #26 Posted September 3, 2008 Lenses manufacturers have work to do... yes. it would be great if canon set out to produce wide angel lenses which can be used on high res sensors without recalling coolpix type image quality......as nikon is doing now with their new generation of lenses. what do i do with 21+mp if the (wide angle) lenses are only capable of resolving 6mp or less (in the corners)?the 50D customers will soon complain to the dealers that their old 30D produced higer quality images. peter Link to post Share on other sites More sharing options...
wildlightphoto Posted September 4, 2008 Share #27 Posted September 4, 2008 Advertisement (gone after registration) Lenses manufacturers have work to do... All the purchasers of the camera need are a stock of R-to-EOS adapters, problem solved. Link to post Share on other sites More sharing options...
