I found the Tamron 70-300 LD Di to be very good, sharper than my FA 80-320 and F 70-210. they're cheap to buy too. I've not tried the 55-300 but hear it's very good.

It can no longer focus at infinity beyond about the 180 mm setting. It seems to work OK otherwise. I'm considering the DA 55-300 mm as a replacement but I've seen a couple of FA 100-300 zooms go for reasonable prices recently. Does anyone have experience with the FA 100-300, particularly in comparison to the 80-320, which I think is excellent?
