As I mentioned in an earlier thread, I am in Lembeh shooting a D3x with the 105 VR, Aquatica housing and one YS250 (I'm kicking myself for not bringing the second strobe). The image quality out of the camera/lens is beyond what I expected. This shot was done today of a lionfish at less than 1:1; this is a 100% crop of the original RAW image, unretouched or post-processed:

And the complete image:

Image shot in Manual, no-TTL, f18, 1/100 sec, strobe @ full (I think).
