Was the question of a future Pentax MILC system not even raised?

Ironically, the smaller ILC formats like 24x16mm (APS-C) and 4/3" are where EVF cameras have their greatest advantages over SLRs,...

Many cameras these days—even in phones—can capture more dynamic range and better tonal scale in shadows than 8-bit JPEG record, and even simple common adjustments of levels as offered in basic ...

"Way to leverage mirrorless for smaller and lighter lenses, ..."

(1) "smaller and lighter lenses" only applies for wide angle coverage where it helps to have rear element less than 40mm from the...

I never found that with the 135 format HP5 that I mostly used; at worst, a little fumbling in the dark to get it spooled for the developer tank, and moderate care with water temperatures, but...

I've got nothing against B&W find photography—in fact I still have printing paper, contrast filters and such waiting for if and when I find darkroom access again—but what does this no-name film add...

I do not see anything to distrust in this article. It just says it is a photo of the intersection _where_ the accident happened, which seems to be correct. Are you thinking that there is a claim ...

Post-processing by deconvolution or such cannot completely "take the place" of a larger aperture; it can just improve sharpness a bit and so achieve a given resolution with a smaller aperture; ...

The WPP data is the article shows little about "DSLR vs EVF"; it reflects the dominance of the press photography field (which is far from including "all the best photographers") by the technology ...

I just use Bart van de Wolf’s because it had illustrations! The peer-reviewed stuff on legitimate medical research sites is a tougher read, as is anything on PSFs and 2D Fourier transforms The ...

Agreed on all the practical (and theoretical) limitations; my point is only that there is _some_ room for recovery of resolution in post-processing — which I believe as is practiced in microscopy, ...

Maybe, but diffraction deconvolution is an established method in microscopy and such, with plenty of peer-reviewed sources. I agree that there is a theoretical limit on how much improvement can be ...

That is about the “raw” optical image (the formula relates to the Airy disk size that I referred to); it does not rule our subsequent deconvolution image processing to partially undo the effects ...

Can you quote the mathematics to back that claim up? I am a professional mathematician but not expert in this field, so I would be interested to read hard mathematics on this, not just the formula ...

Right: under any given viewing conditions (displayed image size size/viewing distance) a higher resolution (higher pixel count) sensor at the same f-stop will give a somewhat sharper image, not ...

Mathematically, diffraction can be an invertible transformation of the signal, or closely approximated by an invertible transformation, so it is conceivable that with a distinctly oversampled ...

Correction: it is like 4:2:0 chroma subsampling, where each 2x2 block of pixels gets a single value for each chroma channel.

I expect that the luminosity resolution will be limited by the lens rather than the sensor, both through diminished contrast (lower MTF in fine features) due to diffraction and also the...

@cosinaphile, yes the color resolution is as for a 12MP sensor with standard Bayer CFA, but luminosity resolution is distinctly better. The sample images at the site I linked above show the...

@Yak27: I think it is more like 4:2:0 (halving chroma resolute tin both vertical or horizontally), but I like your approach of comparing the resolution effect to these standard sub-sampling...

The 48MP (8000x6000) 1/2" (8mm diagonal) Sony sensor has 0.8 micron pixels in strange 2x2 color blocks, so at f/1.7, there will be some distinct loss of contrast (lowered MTF) due to both...
