I love Lomography, however I hate that I have to juggle multiple cameras.  Lomography has now announced that you can get an adapter for your Nikon or Canon camera to use their lenses!

Description: Diana F+ Lens Adaptor:
Always wanted to achieve those breathtaking Diana F+ effects with your Canon EOS and Nikon F Series SLR cameras? Now it’s possible with the Diana F+ SLR Adaptors. Sweeping wide-angles and crazy Fisheye techniques? Bring it on!

The Diana F+ SLR Adaptor is compatible with the Canon EOS and Nikon F Series SLRs. Now what does this do? It brings the world of Diana to your SLR cameras, yielding creative possibilities that were once limited to Diana F+ cameras. Just attach and twist the SLR adaptor to your Canon EOS or Nikon F mounts, and you’re ready to use your chosen Diana F+ accessory!
– Compatible with Canon EOS digital SLRs and Nikon F Series SLR cameras
– Use with the Diana+ Fisheye Lens, Telephoto lens, Wide lens, Close-Up and Super Wide lenses.

Now just make it for the Nikon D Series and I’m be really really happy!
