Maximum ISO ratings on cameras have nothing to do with pixel pitch. They are completely arbitrary numbers for marketing. Yes, the a7s/II has the highest ISO available of Sony cameras, simply...

@808_freedive:
everything you just wrote is nonsense. The Leica 50 Summilux ASPH will not only cover full frame, it will cover 44x33 medium format sensors with excellent edge and corner sharpness...

Well, for one, they don't have autofocus. Nor do they have any electronics in them at all, unlike pretty much all other lenses.

They're also incredibly expensive. Size, quality, price.... pick...

Christos Cloud yes, correct. Nearly double. It's important in the sense that larger pixels will have better per-pixel acuity and less noise *at the pixel level*. Downsizing and such mostly negates...

Yeah, the 'flagship' Hassy and (especially) Phase One are all larger sensors.

I like the X1D in many ways - I love the simplicity of the layout and form factor, I love the lenses, and I especially...

jaywalles You have more like 2/3 stop advantage over FF, not 1/3. But most of that advantage is lost if shooting against a base ISO of 64.

But there are other considerations as well beyond light...

Take the square of your crop factor and multiply by the megapixels to get equivalent density.

M4/3 - 2^2 x 20 = 80mp FF equiv
APS-C - 1.5^1.5 x 24 = 54mp FF equiv

for example

pentaust the D810/850 and Z7 all have true native 64 ISO. It's not an extended ISO.

Depends what camera you're talking about. The GFX cameras use the same sensor that's in the Hasselblad X1D, H6D-50c, Phase One IQ250, and Pentax 645Z. The 44x33 sensor is more common than the...

It's mainly that 28mm and 35mm are the most common focal lengths for standard everyday shooting - 24 is a bit wide for a lot of stuff (though I love it), and 40-50 is a bit tight.

Ricoh has a 21mm...

No, he's just a reasonable human being making a reasonable statement
