Major overlap doesn't have anything to do with chromatism, if anything it makes it worse. Explanation of major overlap is that the ancestral placental mammals were nocturnal and had only 2 types of ...

Nice. With back focal length of 32,45 same optical prescription could be probably used with some aps-c SLRs

This more proves "largely unrelated" by OP rather than otherwise. With whopping 2.7x difference in sensor diagonal, the size difference (width) is about 1.25x. Also A7C has IBIS, focal plane ...

Main drawback of color splitter system -- big bulk.  This is a major issue when lens used is  small like "nifty fifty".  A big lens such as 100x zoom dwarfs any size issue with color splitter. At ...

With sensor readout getting faster and better, IBIS eventually will be replaced with stacking short captures

They don't have to be big. 50/1.8 is replaced with, say, equivalent 90/3.5 and these bulky 50/1.2 might be replaced with much simpler 90/2.4. Earlier, mirror box -- which had to be match sensor ...

APS-C DSLR from now is often larger than FF film SLR because of making large sensors was  (is) expensive. Remember how K.Rokcwell, being a Nikon fan, justified that digital is just fine with aps-c ...

@David Hull
Canon probably licensed them certain IP for this

@Tom Holly
Studio scene comparison tool, here, on dpreview shows otherwise: 90D with 50/1.4 produces sharper images than 5DM3 with 85/1.4.

You said "same lens", probably a zoom lens intended for...

@ottonis: the VHS example is a red gerring; Topaz AI wasn't trained on datasets with old VHS images.

mount to m43 with infinity focus

spoiler: it can't

Because most new cameras fitted with IBIS, there is little reason to do what you suggest, because IBIS can do this and also sub-pixel shift. It'd be more interesting if a sensor could change its ...

is it a production lens? Why is it 220 FOV? Superficial googling gets me 180...

If all you have is a hammer pupil magnification...

But collectors can collect cheap replicas of originals too!

These prices for simple 8-element lens make it look that it's cheaper to order manufacturing. Oh well, actually it's a collector's item, not a tool now.

Rear mounted contervers have some limitations. Some people want to use teleconverters with some lenses with do not have empty space reversed into their rear, but it's not possible for MILC or with ...

How is flapping mirror much complicated than IBIS or focal plane shutters, which most mirrorless cameras retain?

f/0.5 is in the air. You just need to have rear element touching the sensor to have high-index (of 2.38) to be in contact with sensor, making f/0.21 possible.
