    Most people I know use APS-C sensor cameras. When they talk about different lenses they use I find myself trying to figure out what their field of view is compared to lenses I use. One day I got sick of the math and made myself a cheatsheet :) This just has the current and announced focal lengths of native :43: lens. If you want me to add more, let me know.

    Side note: I tried to do bbcode tables, but apparently they don't work here.

    Don't forget Canon's 1.6x crop.

    I actually hate APS-C's crop factor, maybe I just fail at high school math.

    If you look at the raw data, I simply divided the full frame sensor size by 1.5 :)

    Is there any real demand for 1.6? If so, I'll go ahead and do it. 1.5 and 1.6 seems so close together that I didn't bother the first time around.

    It's not too bad. The actual crop factor can be obtained by dividing the length of a full-frame sensor's diagonal (43.3mm), by the length of the cropped sensors diagonal. So even Nikon APS-C varies - from 1.52x to 1.56x...
