I purchased two 10D's last year and immediately began checking them out for focus problems. I had read what Chuck Westfall (Canon) had written on the Galbraith forums about the 10D's sensor which actually reads an area considerably larger than the viewfinder reticule. He provided a drawing from the Canon tech department that showed the actual focus detection area, I think understanding that cured problems for a lot of people.
Anyway I tested my cameras using a test sheet with mm ruled markings on the left side of the frame and a single line in the middle of the frame to prevent any confusion in the AF sensor (center reticule used). Both 10ds will often front or back focus (at 2ft the focus might be off about 10mm with my 28-70 at 50 and with a 300mm at 10 ft might be off an inch) , but the focus line was always in the depth of field wide open. In consumer grade AF systems this is often the rule of thumb. I use 'L' series lenses, I have heard that the real focus problems may be limited to the consumer lenses. My final deciding factor was: was I happier and more productive using the 10D over the EOS3 , and after 8 months I can say ,for sure, yes. I still scratch my head and wonder why the occasional shot was not sharp, but I did that with film too. I think the current status of the issue is, an awful lot of people bought 10ds and are happy with them. I will be getting a mkII at first opportunity , but will keep one 10d as my backup. -----Original Message----- From: Howard Grill [mailto:[EMAIL PROTECTED] Sent: Sunday, March 21, 2004 5:41 PM To: [EMAIL PROTECTED] Subject: EOS Frozen with indecision I have decided to make the move to digital and am waiting for the 1D MkII but it appears that it may not be until early summer that one will be generally available if not already on a waiting list. Anyway, I was also considering getting a 10D to use until the MkII and then using this as a back up and as a lighter walk around the street type camera. However, I am frozen with indecision about getting it based on all the hoopla about focusing problems with the camera that are either there out of the box or develop over time...just curious about you folks opinion about the current status of this issue. Also up to what size prints do you feel are still 'really good' can be generated from the 10D files? Thanks.
