Ive got a 5d2 and 35mm 1.4 and I just got both of them back from CPS service. I was getting soft/out of focus shots so I sent it in.
They said "It was found that the adjustment of the circuit board was inforrect and ectrical adjustments were made" on the 5d2
On the lens: They said the whole autofocus system was broken and replaced it all, plus some other stuff which I thought was crazy. I dont know how this could have been as its a fairly new lens (UZ date code) and there was barely a scratch on the body of the lens, if one at all. Thing is, the autofocus would lock on every time, nothing was in focus though. Anyway, they didnt charge me for it so im grateful they covered the repair.
But it still acts the same. It seems to focus correctly at apertures above f2. But there is a major difference between 1.4 and f2 in the sharpness. At 1.4 its just not sharp.
I did notice that when using a flash, the sharpness/focus seemed to be greatly improved.
Should I send it back in? If I do I want to better pinpoint what I need them to fix and im not sure I know what the problem is yet.
Thanks
Matt
This is not uncommon with the 35 1.4 lens. Our local retailer (Roberts Camera) had three copies on the shelf that exhibited the same problem. Canon NJ service finally fixed the one I bought but often it takes a couple of trips to the service center to fix this type of thing. There is something strange that happens with some 35L's that makes them a dog at wide apertures. There is an easy way to test for this by focusing on something more than 30 feet away using an aperture wider than f1.8. The affected lenses will never accurately focus on the distant subject. The results are better up close, but still not sharp, even with micro adjust.
I offer this info cause I went through months of sorting through this with my lens. Not fun.
