At the moment I'm really into Lanscape and Macro/Nature photography.
I have been using a Nikon D40 for the first 18 months of my Photogrphy journey and have now recently upgraded to the Nikon D90.
I have the following hardware:
Nikon D90
18-105 mm Nikon VR
Sigma 150-500mm OS HSM
Nikkor 50mm 1.4 AF
Kenko Extension Tubes
SB-400
SB-600
