Sony Alpha fit lens decision

[Sarin]

I'm in the market to add another 1, maybe 2 lenses to my camera bag, the problem is i'm having a hard time deciding what to buy. I currently only have the kit Sony 18-70 which came with my a200. I think i have narrowed it down to the following lenses but am open to any other suggestions.

Minolta 50mm f/1.7

Tamron 17-50mm F2.8 Di II LD NAF

Tamron 28-75mm f2.8 SP Di

I'm interested in portraits and still life which i think the 50mm could cope with well but i also like landscapes. So a couple of questions:

1) Would i be worth getting the minolta 50mm and the tamron 17-50 or would the Tamron cover both aspects and do the job of the 50mm prime as well?

2) Other than the obvious higher f-stop, is it worth me getting the 28-75 considering the sony kit lens is 18-70mm f/3.5-5.6?

Any comments or suggestions would be greatly appreciated as would other ideas.

Well, back in my film days my EOS invariably had a 50mm f/1.8 attached to it so I went for a 30mm f/1.4 Sigma for my regular lens and I think it's fantastic. It'll do portraits but at 45mm (in 35mm film camera terms) you need to get in a bit close.

what's the cost of the sigma 30?

minolta 50mm, are increasing in prices on ebay. hope sony release a similar one and prices to match those that canon members get

£269 for the sigma.

it's better built & optically better but you are also giving up some range at the wide end.
