I'm glad I found this site recently. I was on the verge of purchasing the 70-300 APO for my Alpha300.
Now I have an issue with what to buy now (took me ages to decide on the sigma).
I'm a newbie to DSLRs and want a zoom lens to go with my A300+standard 18-70 kit lens.
Should I know be looking at the Sony 70-300 or the tamron 70-300.
Unfortuately my budget is limited, hence the Sigma APO seemed the logical choice.
Thanks in advance
