Hi
I bought a secondhand 1ds3 a couple of months ago and I'm struggling to get consistent results with the focus of my fast primes. I'm using it with 35 f/1.4, 50 f/1.2, 85 f/1.2, 135 f/2.
I've calibrated the lenses - they needed a lot of adjusting. The 85 (mk1) for example needed +20, it's not even close until +18. Other lenses didn't need quite so much.
When focusing it just seems a bit hit and miss - even on static high contrast subjects such as a test chart. Occasionally it is spot on but for the most part it is out.
Moving from a 5dii I feel a bit let down as I used the 1.2 lenses most often at 1.2 and had a very high keeper rate of getting the focus spot on by using the center point focused on eye and re-composing.
Is the Af tech of the 1d3 not as good as the center point of 5d2? By this I mean accuracy - not speed or anything. I'd rather have a slow accurate AF than a fast and inaccurate one. Is it likely the body just needs servicing?
Any thoughts much appreciated. I cant afford a 5diii at the moment but am wondering if I'd be better with a 6d for it's accurate center AF point ....
