[Leica] Highly Intelligent Crop Factor Overview

[john at mcmaster.co.nz (John McMaster)]

I would expect far better 20"x16"s from an APS-C than I would from 35mm 
film.....things have changed with the digital world, calling things crop 
sensors only makes sense when using native 35mm lenses, using native lenses 
then they are full frame for that lens ;-) 

Have you used any recent camera, e.g. Olympus m4/3 or Fuji X series never 
mind the Nikon D810 or Leica M(240), to see how sensors have progressed 
since the D700 and many now have no AA filter for extra definition...

But few of us for some reason used 18x24 format. Otherwise known as half 
frame. Before that 18x24 was called  full frame. The first Leicas' s, 
Barnack were known as "double frame" which was 24x36mm.
35mm movie film could work for stills long as the standard movie film format 
already used on some still cameras was doubled. This was crucial to the 
original Leica concept. We want a very compact pocketable camera; but we 
don't want the format smaller than it needs to be.  It needs to be using 
more sprocket holes... We want it as big as is possible or practical. Years 
later Hasselblad/ Fuji camera out with a pan camera using 35mm film which 
they marketed as a medium format camera. Maybe it was triple frame I don't 
know but you get my point.

The great compact cameras of the 80's on 90's could have been half frame and 
we'd have gotten 70 on a roll verticals. That could have been a selling
point. Instead they were   full 24x36 frame and a blow up the size of your
wall could look just as clear and sharp as one made with a honking 35mm SLR 
with moterdrive and batter pack weighing many pounds.

To me ever since the Olympus OM1 and the Rollei 35 it taught is you wanted 
the biggest possible format in the smallest possible camera. A compact 
camera need not have a tinier than necessary format. And this is a basic 
Leica idea as well. The idea behind the Barnack.

Nowadays we we get a compact camera the format has not stayed the same. Its 
been shrunken to a size they don't even want to tell us about. Only one 
company Sony with its RX 1 has done that. And we don't want to think about 
it because it cost three grand USD.
So we pretend that needlessly shrunken formats equal quality image making 
worthy of Leica glass and Leica conversation.
Its Weasel words.
We pretend like the bottom line is pixel resolution.
Which is like saying put slow film in your Minox blow it up as big as your 
wall and pretend you like it.
The long and short of it is most the threads on the long now are concerned 
with toy cameras.
"The pros' are all using them now!"
No they're not.
"The sensors are just as good as full frame!"
The full frame sensors have been getting better too.
"They are only needed for Pro's"
Like saying 24x36 film is pro size and amateurs could all be using 18x24.
Serious amateurs didn't use 18x24 because they weren't stupid.
But if they were sold for less money many they might have.
