Video & Movie / Wide lens for video

« on: November 25, 2012, 03:16:16 PM »

I've been shooting for years and looking to get into video.  I have L series lenses 16-200mm.  I have yet to find a definitive answer to this question:

Are ultawide 12mm, 14mm lens really popular in the video field and if so, why?

EOS Bodies - For Stills / APS-C vs megapixels for zoom

« on: September 28, 2012, 06:03:09 AM »

Hi !

I've got a 40D APS-C with a 1.6x crop factor.  That means my 70-200 is actually x1.6 or 112-320mm. 

Given that i'm shooting at 10Mp, if i upgrade to FF a 5Dmk3 given the grater number of pixels how would I calculate the zoom of a 10Mp image cropped out of the center?  I'm thinking it's greater than 1.6 but not sure how the math works out.
