| p.1 #1 · Unreliable AF on 7D with FW 2.0.3? |
Before I bought the 7D, I had a 50D, and all my lenses focused perfectly with that camera body.
I recently updated the firmware on my 7D to 2.0.3. Was running 2.0 before (with no obvious issues).
Right away after updating I noticed that the AF had become very unreliable. It had a hard time locking and was hunting way more than before.
Especially with my f/1.4 lenses, a Sigma 85/1.4 and Canon 50/1.4, the AF is way off. The camera indicates that focus has been locked, but when I view the picture it is often very front focused. Sometimes though (about 10-20% of the time), the focus is spot on as it should be.
I also have a Canon 100/2.8 USM Macro and a Sigma 17-50/2.8 OS that show the same behaviour.
Actually, my only lenses that focus as they should right now are my Sigma 120-300/2.8 OS and Tokina 11-16/2.8.
I've tried using all the different AF-options, but nothing seems to help. I've reset the camera settings, done a hard reset, cleaned all connections between body and lenses.. Nothing has helped. It really seems like FW 2.0.3 is the bad guy here.
Has anyone else noticed this? It's driving me insane at the moment..
This exact thread has also been posten on canonrumors.com, and there are quite a few experiencing the same issues Im afraid..
