So would you stick with what I already have or go with the 35 f2
I would like to see what an f/1.4 lens operates like - never had the desire befor to be honest
What would be your choice
I went from the 1.8 AF D to the 1.4 AF-S and definitely noticed the difference, it's an amazing lens the 1.4. I prefer it to my 30mm 1.4.
However, for some portraits and all street I tend to use the Tamron 28-75mm 2.8, which is a cracking all round lens.
As a standard lens for a D300 - for interior shots and some general walkabout street photography.......
?
...I'd say the different focal length is going to be more useful to you, but still may not be wide enough for interior shots (especially considering the crop factor).
Personally I'd go with the 35/2 - unless you want to do people sort of stuff, I find a 35mm much more useful. It also focuses very close, so is nice for unexpected close-ups,
For value, the 50mm f/1,8 is hard to beat, both the 50mm f/1.4 and the 35/2 are much more expensive.
Looking at lenses below 2.8, I'd echo the above comments; however, if you were going for a 35, I'd seriously consider the new AFS35/1.8 unless you really see yourself going full-frame very soon.
I think you're asking too much from one lens.
35mm f2 great little lens
Sigma 30/1.4

I think I will have a look at the Sigma - Is that for FX or is it a DX only lens? I would like to have a FF body in a year or two![]()
the Sigma 30 f1.4 is a well regarded lens, and certainly fast enough to do what you want.
