Gary,
I experienced similar results with a Tamron 35-105 F2.8 zoom. Despite the
lens' speed, it was difficult to focus accurately even at the 105mm focal
length. It was far more difficult to focus than a Zuiko 100 F2.8. The Popular
Photography test results for this lens were spectacular, but consistent,
quality results were difficult to achieve due to the focusing problem. After
my very favorable experience with the Tamron 400 F4.0, this lens was a
disappointment. It is since been banished to a Nikon user. Adios.
