Yesterday I had returned to me the two Sigma lenses I sent off for work to be done on them.
The 24-70mm F2.8 lens had its chip upgraded so that it would work properly with the Nikon D200 camera. The 28-300mm lens went in because, basically, it was out of focus.
Anyway, seeing as it was a nice day today I was able to test both the lenses out. The 24-70mm works perfectly. However, the 24-70mm is a bit of a lemon.
Sigma told me that they’ve replaced the complete optical package within the lens (and the reason for the delay in returning the lens was because they had to order this from Japan). Before it left, the lens, other than being slightly out of focus, worked properly. However, now it won’t focus beyond about 100ft. That’s right, the focusing system is broken! So, I’m going to have to go through the hassle of sending the thing back. What a pain.
You have to wonder if they actually test the lenses at all before shipping them!
