This was taken with a Nikkor 35mm F2
The last photo was taken with a Sigma 18-50mm F2.8
I got into photography because of my cat. Because point-and-shoots just didn't do the job. And anything higher than a F2.8 just couldn't capture him in room lighting.
The 35mm F2 is a GREAT lens, very sharp, fast, and small depth of field for that great portrait effect.
