My 5D3 is a great cam. Coming from the 30D I set its AF by suggestion of my brick and mortar dealer on the center AF point. In 90% of the cases it works great.
But compared to the 30Ds center AF point which was quite snappy even at very distant and dim light in moonless nights, the 5D3 AF is struggling a bit. Still being in my learning curve since August, what are the mistakes by my side while handling my gear.
AF on the moon: no problem.
AF on Jupiter: mostly no problem.
AF on some distant, dimmer light at full darkness...not always working.
Guess I've read about slight issues here, so thank you for any help
Cheers, Peter in Switzerland.
I have similar issues with the 5DIII in very low light situations
. Can't say about the 30D but my 7D is also unable to focus in similar conditions.
Maybe we are expecting too much from the AF system.

When it comes to gear, it is better to vote with your wallet. Bitching on online forums like a lunatic doesn't get you anywhere!
