solsang: To remember easily: Crop factor - to know amount of light: Sensor Area - to figure out print sizes: Length and Width
I have adviced people and compared cameras and lenses having to use what i could remember by heart, so crop factor has always been easiest, and i have not needed exact figures since sensor quality and type varies anyway.
Being able to know that apsc are around 1.5, m43 are 2, 1" are 3, fuji ⅔ are 4, big sensor small compacts are 5, normal compacts 6 and phones kind of 7 have given me a very easy and understandable idea of depth of field, amount of noise, lens weight and raw possibilities :)
"To remember easily: Crop factor - to know amount of light: Sensor Area - to figure out print sizes: Length and Width"
What ?!
paul cool: what about multi aspect ratio sensors ,all manufacturers should make these to cover the image circle ,i prefer 4:3 for portrait ,but for landscapes i prefer 3:2 .
Panasonic GH1 does that by keeping the diagonal constant. :-D
ChelseaPhotographer: All the talk that APS-C produces the same image quality as FF is just nonsense. Both systems have advantages and disadvantages, and one of the disadvantages of APS-C is that it simply cannot produce the same IQ as FF, as much as die-hard APS-C users would like to think. And one of the disadvantages of FF is that it is generally a bigger and more expensive system. That is unless you buy the expensive Fuji models which cost as much as full frame and can be bigger and heavier, and still produce inferior IQ...
Is there a comprehensive Standard for camera IQ - like there is for cell-phones?

If so, one could truly compare APS-C and FF sensors instead of just using vague terminology ....
A bit like Sigma's "fp" becoming "FP" in posts, interesting how "L²" immediately became "L2" in the text following the quote, grump.
Ted.
Good one!
Love those bubble-shaped cars of that era ... some quite ugly. I owned a straight 6 '51 Chevy saloon for a while ... no good for bootleggin' I'd say ...
Thanks for reminding me of visiting there long ago!
Scottelly: I wouldn't buy anything from a company that doesn't know how to spell their own name.
... or spell their own model names, eh? ;-)
Especially nice with the flat-head screwdriver - so reminiscent of yesteryear.
paulbysea: My first camera was a Praktica MTL3, which I bought in 1977, learnt a lot about how to use a camera and how to get the exposure right and how to focus manually. A big step was getting a 135 mm short telephoto lens. Remember the camera fondly but was very happy to upgrade once funds allowed.
+1.
Kept and used mine until the early '90s until I replaced it with a Kodak 643 point-and-shoot. Horrible little thing, quickly replaced by a Nikon DSLR ...
"with the aim of intersecting the asteroid" ...
That would "intercepting" - pardon my pedantry. :)
Morvegil: SO what's the advantage of a Foveon sensor?
oops - text deleted
Scottelly: Adobe - don't install it.
Amen to that, Scott!
Greg OH: The problem is financial hanky panky that has nothing to do with photography. Remember Enron? Olympus is the Japanese Enron.
I remember Enron well. I was working for Dynegy at the time, a fine energy company that got scuttled by the Enron debacle.
Excellent. What a magic moment!
That would be "Wetzlar", not "Wetzler" ...
xpatUSA: I worked on XH558 long ago at RAF Waddington. It's predecessor XH557 was always going U/S ... we hated it!
Obviously, @MannyZero has no idea what "Duxford" refers to!

RAF slang for "unserviceable" i.e. has a problem ...
