The Sigma 1-70mm macro extends 7-1/2 inchs; can't house this puppy. If you are doing buildings, I suggest 15 to 24 mm focal lengths. I don't think you'll much for $400 a lens unless you go primes. The Nikon 18-200 DX VR is a nice walking around lens, but would be most of your buget. Sell your current glass and buy the good stuff.

Well, I only have a Nexus D80, but I'll add my two bits. Maiden voyage for this rig was Bayan Bay in April. I used 2 Inon Z240s with and optical link in sTTL most of the time. The bay was usually mucky at that time, so I did only close ups and macro. The sTTL was right on; only requiring normal extra dark or light back ground adjustments. I used the +/- adjustments in the camera and left the strobes in STOL. The rig still had plenty of juice after taking 300+ shots. Pros: D80 has all the controls and features I need. Small and compact. Optical connections - no corrosion and minimal maintenance. Z240 - plenty of power & excellent sTTL. Cons: The viewfinder (both of them) suck big time. I wish Toshi would redesign and retro fit. I have had corrosion problems with Nikonos and Nexus housing using Ikelite strobe. I think they ground thought the housing. I used zinc plates to minimize this problem. Has any one tried the Sigma 18-50 mm f2.8 macro (well sort of at 1:3) in the Nexus housing - either dome or flat port. If so, what zoom gear, extension, and ports?

I checked out the Inon 45 deg. viewfinder above water at a dive expo. While the 45 degree angle might be good for some close to the bottom work, I do not like the attitude for general shooting. I love my ole Rollie TLR, but composing is much slower than an SLR. I share the concern about mounting on an acrylic back. I think the whole back would need to be replace with a new plexi back an aluminum mounting plate for the viewfinder. OR, best yet Toshi could design us a new 100% view of the camera view.
