A fisheye lens creates a lot of rectilinear distortion (straight lines are curved) which I'm certain you wouldn't want for real estate photography, and you probably wouldn't want for your other business either. What you may want is an ultra-wide angle lens. I really don't think you need a 180 angle of view, but something wider than a 90 angle of view might be good.

I presume you have the 18-55mm kit lens, and that 18mm isn't wide enough (35mm equivalent of 27mm). Here are some lenses that can go wider, and might be more appropriate for some of what you're trying to do:

Sigma 10-20mm f/4-5.6 EX DC HSM (Tested) ($479 at Adorama.com)
Tamron 10-24mm f/3.5-4.5 Di II LD SP AF (Tested) ($449 at Adorama.com)
Sony 11-18mm f/4.5-5.6 DT SAL-1118 (Tested) ($649 at Adorama.com)
Sigma 10-20mm f/3.5 EX DC HSM (Tested) ($649 at Adorama.com)
Sigma AF 8-16mm f/4.5-5.6 DC HSM ($699 at Adorama.com)
Sigma 12-24mm f/4.5-5.6 EX DG Aspherical HSM (Tested) ($859 at Adorama.com)
Zeiss ZA Vario-Sonnar T* 16-35mm f/2.8 SSM ($1,749 at Adorama.com)

Notice that the only lenses that would work on a 'Full Frame' dSLR are the Sigma 12-24 ($859) and the Zeiss 16-35 ($1,749), plus the Sigma AF 24mm f/1.8 EX DG Macro ($449 at Adorama.com), the Sigma AF 20mm f/1.8 EX ($519 at Adorama.com), and the Sony 20mm f/2.8 ($600 at SonyStyle.com).

TCav, I have not noticed any real distortion but not getting the full curve in the field of view is probably the cause of that. I bought a body only as I had a box full of lenses. Other than the 16mm my smallest lenses start at 28mm. (28to85 and 2 different 28mm's) My newest lens dates back to 1992

The short lenses are expensive for the faster ones so if I had to look at multiple lenses I thought it might be time to think about a full frame body. I do not like buying in the first group of a new product that comes out and prefer to buy "last years racecar" for lack of a better term. With all of the new models reported to include video I thought it might be the right time to look for deals.
