I did some tests on the Tamron 35-105 f2.8 and was not that impressed.
Wide open there was considerable corner light loss and although the
centre resolution is very good I thought the edges where rather poor.
It also suffered from quite a lot of barrel distortion throughout its
entire range despite an aspherical element. I also thought that my
sample was at best 1/2 a stop slower than f2.8 wide open.
