| p.1 #20 · Canon 5D Mark III focus question |
Just upgraded to a Canon 5D Mark III myself with 3 new L lenses, and it's not focusing properly at multipoint AF. When I shoot a mountain with all points focusing on it, the focus is several hundred meters off. You can see it in the water. Shot hundreds of tests, all out of focus. Quite pronounced with a brand new 70-200 2.8 L II IS lens. I'm not even talking about any moving subjects or any fancy modes, I'm talking about still subjects with plain vanilla multi-point AF, what the camera is designed for general use. Please don't tell me to use only center AF, I want to use it with multi-point AF as advertised, with fast moving travel photography.
Also, we found at least 4 L lenses defective right out of the box, the lenses are misaligned and one side of the frame is not sharp--really shocking. We're talking defects that should have never passed QC.
Many tests shoot to death indoors on close subjects, but many never tests on distant subjects and don't see this. You may want to try more tests and check your camera thoroughly. Shoot with tripod or with super high shutter speeds to eliminate any possible camera shake. Try to shoot in bright sun with contrasty subject. RAW or Hires L jpeg. View full size 100% on large, good monitor. Would be interested in seeing what you see. Any other 5DM3 owners, I would love to hear from you. I'm hoping I just got a lemon.
Am very shocked and appalled with the results. My 5D Mark II never worked properly with outer AF points, was forced to use center point only and forced to shoot f8 to 11 whenever possible, using tripod even outdoors in bright sun, to get better percentage of sharp images. I pretty much gave up on shooting wide open after seeing thousands of images rendered useless once I got home and saw the results on the monitor.
Canon boasts about this latest and greatest AF system in the 5DM3. I thought the 41 cross type AF sensors will finally solve the issue, but it didn't. This is not minor front- or back focusing, this is major AF misfocusing wherein the entire image looks completely out of focus, unless you have some field in front or back to show where the focus plane is--see samples.
Store doesn't have another body, so am waiting for info from Canon, and/or another body to isolate problem. The official word from Canon is that I don't know how to set the camera properly and it might just be settings. But I've heard the same line before, with another camera which took three trips back and over a year for them to admit is not working properly.
Even the lowest priced SLR with kit lens should provide good AF sharpness. Spending 10K on new pro L gear and getting nothing sharp is ludicrous.
Apparently there are those that flame posters that are critical of Canon products. Please note: I am a long time Canon fan, supporter and promoter., and a full-time pro. I have purchased well over 100K of Canon gear during my career, and have been published thousands of times. I have recommended nothing but Canon to all my colleagues, friends, assistants, workshop students and readers. I reviewed the Canon A2E with eye control AF years ago, for the top Canadian photo magazine, and gave it the highest praise. I tested it with models running towards me with a 300 2.8 L lens wide open and the performance blew me away. I reviewed the original 5D for a British magazine and recommended it highly. I talked a colleague who had over $14,000 of Nikon gear to switch to Canon after showing him my images. But frankly, right now I can no longer recommend Canon, unless things change.
I have no reason to bash Canon, and am just stating facts. I still have tons of expensive glass and would prefer not to switch. I am frankly just wanting to have a Canon camera and lenses that work properly. Maybe I got another lemon. But instead of being quiet and just accepting all the poor customer service and products from Canon, I have decided to share with others, so they know they are not alone if they are having issues. And hopefully help convince Canon that they should really change their arrogant attitude and improve their service and products before they lose even more supporters.
