Dear Photo Nutters , Lately I have been bitten hard by the TS bug. I recently bought two M645 Mamiya lenses (35/3.5 and 120/4 macro) and a Mirex TS adapter and am having great fun with them. Trouble is, I now want TS in a wider FL. As the 35/3.5 is the widest FL in the M645 Mamiya range that means just one thing: Canon. More specifically, the 17/4. I am focusing on that lens as I am in the APS realm now (40D) and will probably stay there (7D). Stitching pictures for panorama pictures currently does not interest me. Shifting up or down will still be narrower than my 10-22. That means that the only benefit I'll get from it is when I tilt it, right? I am not a die hard landscape shooter. On the contrary. I mostly shoot portraits and macro. In fact, the 10-22 is my least used lens. Therefore, paying so much money just for the tilt feature seems outrageous to me. It seems to me that the only true benefit I will get from it is if I go FF. Even on 1.3X it is narrower than my 10-22. Any thoughts? Happy shooting, Yakim.
