Yes, this is without the diffuser, I don't have any samples with it on but I could visually see the difference on my dives - no hot spot.
LOL, that reef creation done for an UW photo workshop my LDS put on...we had 4 hours of course work and spent an hour in the pool trying out what we had learned...it was awesome. I think the shop is going to keep it for future classes.
Thx, I really like this camera/rig...not too bad for my first images. If I can't get my asking price, or something close, I may keep it as a second rig and use it for macro work...it would be nice to have a 7D and an S90 on a dive together. The 7D is a great camera and I love its video capabilities...can't wait to test it under the seas...
