Relative noob here: I'm looking for a lens to take pictures of my 6 month old son who is a wriggle worm! He's constantly moving, plus having a house that is fairly dark inside and in constant low-light conditions makes it very challenging.
I currently have a D7000 with the 18-105mm lens. F/3.5 isn't cutting the mustard. The pictures coming out heaps blurry even on high ISO. He just won't stay still!!!!
So I "think" i'm looking for something with wide aperture so that I can pump up the shutter speed?? If it can contribute to awesome bokeh factor as well that would put the icing on the cake!
How would these compare?
Nikon AF 50mm f/1.4D
Nikon AF-S 50mm f/1.8G (the new one that's not out yet, I know you can't give me hands-on example, but theoretically from the specifications)
Nikon AF 35mm f/1.8G
Or do you have any other suggestions? Would prefer something between $3-500. Less is a bonus as I need to buy a tripod too! And a flash.. but that's dowwwwwwwwwwwwwwwwwn the track.
Thanks in advance,
