I was woundering about the 400mm primes some more?
I posted a couple days ago about my older Sigma 400mm 5.6 AF prime lens i was having trouble with. But i really like the lens I know there are a couple differant models out there.
400mmAF5.6prime APO HSM macro
These are all SIGMA lenes that they came out with it seems the first one on the list has a real problem with Sony Alpha's and the AF tends to strip out .
I have been looking at a used Sigma 400mm AF 5.6 APO At the local camera store for about 200 with a 30 warranty i was woundering if these have the same problems as the first 400mm sigma prime lenes.
