Well I am a flypoop away from sealing the deal on a D700 (and yes I am seeking professional help for my NAS). I didn't think I would be going full frame for awhile, but this deal was very hard to refuse. Problem is, I don't really have a medium length lens for it (see my lens line-up below). With the recent purchase of this body and the 7000, my bank balance is shot BIG time (which is what the Minister of Finance wants to do to me). So, I'm thinking of purchasing a 50mm to tide me over until I save enough for a 24-70.
It seems there are many flavours of this lens and price does vary:
50mm f1.8D
50mm f1.8G
50mm f1.4D
50mm f1.4G
Now the questions. Is the only difference between the D & G models the focus motor? Is it really worth the extra money for the 1.4 over the 1.8 considering both my bodies are very good at high ISO? Which flavour would you recommend considering this is really a fill gap lens until I get a 24-70? Is there any other lenses I should consider that will produce nice sharp images with decent bokeh, without me having to rob a bank?
Thank-you for any input.
