Having issues with my canon 5d ii and focusing with my

Customer Question

Having issues with my canon 5d mark ii and focusing with my aerial photography. When I use my 70-200 i hardly ever have focus problems but when i use my 24-70 i will get maybe 2 out of 6 that are in focus. I have sent the lens in and had it fixed but still have the problem. It does it with a new 24-105 lens that i bought too. They are all L lenses. Been doing this for years but I am really getting frustrated. Anything come to mind?
JA: What's the make/model of your camera? How old is it?
Customer: Canon eos 5d mark ii and about 4-5 old i think.
JA: What happened right before this popped up? What troubleshooting have you tried?
Customer: nothing out of the ordinary. i took the camera and lenses to Glazers camera in seattle and they said my settings are good and had me send the lens in for repair but it is still happening.
JA: Anything else you want the camera expert to know before I connect you?
Customer: no

Have you tested the lenses on a different camera body?

This would help to rule out any possible software glitches or other performance issues on your 5D.
