You need a .5x auxillary lens to get a 17 mm equiv fisheye. You could use this auxillary lens on any new digicam you get. I use a .6x auxillary to get a 21 mm view. I like it,

No. 35 mm fisheye lenses are for 35 mm SLR cameras. There the 35 mm refers to the film size, not the lens focal length which is typically between 8 and 15 mm. What you need for an A75 is a lens adapter and an "auxiliary fish-eye lens". The lens adapter fits around the A75's regular lens, and the "auxiliary fish-eye" screws into the threads on the front of the adapter. IIRC the A75 takes a 52mm diameter threaded adapter, but check the specific one you decide to get.
