Tokina 11-16mm odd exposure issue
Sep 9, 2012

I wanted to repost this thread with I different title than the original thread. I have never seen a zoom lens change exposure at different focal lengths.

With the camera set on manual a .5 to .75 stop difference can be seen at different focal lengths and apertures.

Please refer to the original post here http://forums.dpreview.com/forums/read.asp?forum=1043&message=42373321
