I have had the 7D mk11 for a while now and have used it many times with my 70-200 2.8 L lens and never noticed an issue when shooting aviation or motorsport, but last friday I was working very close to my subject and using very shallow depth of field of F/2.8 or F/4 and i noticed that close in my lens appears to be front focusing slightly
I am going to try and correct it using the autofocus micro adjustment in the cameras menu but if i have no luck then i will have to send it off to canon before the lens gets to a year old and get them to calibrate the lens to the body for me to correct this slight issue
I had a similar issue when i bought my 100-400 and i couldn't get a real sharp shot when it was on my 50d, so that was sent in to boreham wood for calibration
anybody else had a similar issue?

Re: canon 7D mk11 front focus issues
hi,
Did you get to the bottom of the problem, or did you revert to sending it off for calibration?
I've just got rid of my 100-400 L mk1 for the simple reason that I seemed to bin more than I kept - have traded that for a Canon 300mm F4 L.

Re: canon 7D mk11 front focus issues
I printed off a focus calibration chart mounted it to card and did some test shots, then i did some AF microadjustment in camera and it seems to be a lot better now so not had to send it in for calibration this timetalldan76 wrote:hi,

I never really liked using my 100-400 mk1 over 350mm as it was never 100% sharp at the top end, The canon 300 F/4 is a good lens, I had one back in 2006 That i used for a couple of years and it was great on its own or with the 1.4 X converter for a bit more reach, i sold it to fund the 100-400 but have now gone back to a 300 prime and 1.4 X converter
