Welcome to the diving and photography site of Pieter van der Velden
The DivingThe PhotographyThe Tools
For photography I mainly use a Nikon D700. Underwater I still use my D200. The following lenses are used:

Sigma 150mm F2.8 EX APO DG Macro
Sigma 15mm F2.8 EX DG Fisheye
Sigma 100-300 F4 EX APO DG HSM
Nikkor AF-S 17-35mm f/2.8D IF-ED
Nikkor 24mm f/3.5D ED PC-E
Nikkor AF 50mm f/1.4D
Nikkor AF 85mm f/1.8D

My most recent additions are the:
Nikkor 24mm f/3.5D ED PC-E
Nikkor AF 85mm f/1.8D
Sigma 150mm F2.8 EX APO DG Macro
Sigma 100-300 F4 EX APO DG HSM


Underwater I used the following:

Ikelite Housing for the D200 (which I sold in november 2009)
Two Sea&Sea YS-90 Strobes
One Sea&Sea YS-30 Strobe
Nikon D200 (which I sold with th Ikelite housing)

I will however be buying a new housing but am waiting for Ikelite to decide wether the Olympus PEN is worth a housing. I will decide between a Canon G11, Olympus PEN or Nikon equivalent because a SLR housing has become to big for air travel these days.
