Krosavcheg Offline Upload & Sell: Off p.1 #1 · Does the vision impediment affect the manual focusing? I have a slight problem with my eyes, where my left eye is farsighted and right is nearsighted. When I am shooting I am using my left eye. Right now I am wondering (as per topic) if the vision affects focusing? My AF shots come out fairly good - portraits and macro are easily misfocused when using AF, but my MF shots come out completely off! Especially using 16-35mm F2.8L, I have do do a fair bit of squinting and spend ages trying to focus properly. I am using 350D and indeed, the eviewfinder is small. I adjusted the dioptric wheel several times over, but to no noticeable effect. I appreciate any theories and comments. Regards Nov 29, 2008 at 03:02 PM

Amy Klaver Offline Upload & Sell: Off p.1 #4 · Does the vision impediment affect the manual focusing? I'm visually impaired and this drastically affects my ability to MF. 99% of my work is done with AF, only rarely do I use MF for macro shots. I find it's easier to MF during macro shoots if I use smaller apertures, anywhere from f/8+. Dec 01, 2008 at 10:36 PM

mkweaver Offline Upload & Sell: Off p.1 #5 · Does the vision impediment affect the manual focusing? I'm thinking only you can really answer that question. I've been battling an eye disease for 26 years now. Recurrent Cornea Erosion. It causes scarring of the cornea, extreme pain when there's an erosion (which can occur at any unexpected moment). It cost me my studio in 1996 when my vision became so poor I could no longer see to photograph, or to tell whether the photo was in focus after it was printed! A few years ago it was discovered that the lasik surgery caused the eye to produce the glue that sticks the cornea down, and thus a cure for the disease was discovered! Happy days are here again. After two surgeries and one more to go Jan 5 I can now focus the camera and am getting back into photography. Don't give up on it! With today's technology and digital and auto-focus you are in a lot better position than I was in 1996! Dec 01, 2008 at 10:45 PM

Krosavcheg Offline Upload & Sell: Off p.1 #7 · Does the vision impediment affect the manual focusing? Thank you all veyr much for the suggestions. I will do some test shots today using my right eye and hopefully my MF shots will improve. I find it unpredictable to use AF for most of my shots - portraits, landscape and macro. Very easy to miss. However with MF out of focus, AF is the only option atm. Mkweaver: I am very sorry to hear what happened, but I am glad you recovered! Dec 02, 2008 at 05:31 AM
