Originally posted by Peter Zack I can't get what you are saying. You like it with an effective FOV of 46mm but don't at 52mm? Makes no sense to me.
I used the 35 LTD or 43LTD on my K10d. I sold the 35 LTD when I got this tokina. On a 1.6x crop canon, it is nothing special. It has seemed to come to life on the 1.3x crop.
I usually prefer the narrower FOVs, but the pentax 3d effect, IMO, is greatly benefited by the larger sensor and reduced depth of field. I really wish I could use the 43 LTD on a 1.3x or full frame camera!
