Thank you for the suggestions - the Nikon AF 80-200mm f/2.8 D ED I found is just perfect (price-wise - looking up reviews now), so what would be the adapter I need to get that to work on my Sony a65?

Next lens would be a portrait/macro lens.
I hear people say you can use macro for portraits because they are high quality, little distortion, and you can easily get close as required.
So, I'm thinking a 50mm minimum? 100mm max... just because of price...
What are my options out there?

I had a look at the Konica Hexanon lenses, my head is starting to cave in with all these lenses out there lol
