EOS Bodies / Why not higher resolution video?
« on: April 25, 2013, 11:51:04 PM »
High definition video is approximately 2 megapixels. Most of Canon SLRs are 18 megapixels or more. 4k video is 8.3 megapixels. Why don't all the current body's feature 4k or higher video resolution?

EOS Bodies / Safe to leave lens on camera?
« on: April 20, 2013, 02:41:17 PM »
I have my 70-200 f4L USM on my 7D and it got me wondering, with the weight of this lens (and other lenses), is it safe to leave the lens on the body at all times? If so, should the body be facing up with the weight of the lens pushing on the body? Or maybe should the camera be hanging down so the lens is pulling on the body?

Or should the lens be removed and a body cap used?

Software & Accessories / LP-E6 shelf life

I have a new, never been opened LP-E6 battery. I don't intend on using it for several years. How long do these batteries stay good unopened?

EOS Bodies / Canon 7D soft images
« on: December 11, 2012, 03:03:51 AM »
I know this is an old topic but I was wondering if anyone has figured out a "fix" or anything. Maybe the soft images are the result of 18mp crammed into a small APS-C sensor. Sometimes I get tack sharp pictures, but usually I just get average pictures, not as sharp as would be expected. Ive played around with the micro adjustment and it didn't seem to help. Main lenses I use are the 18-135, 50mm 1.8, and 70-200 f4 is usm.

Lenses / APS-C lens mm are correct
« on: December 03, 2012, 07:33:55 PM »
Why are so many people confused about the focal length(s) of APS-C lenses? For example, I have the Canon 18-135mm APS-C lens. For some reason, people think that you have to multiply it by 1.6 for the "correct" focal lengths of 29-216mm. The conversion factor does not apply to APS-C-only lenses. If an APS-C-only lens says its 18-135mm, then it is 18-135mm. If an APS-C-only lens says its 57mm, then its 57mm. Even B&H, in the product description, makes the error by saying its equivalent to 29-216mm.
