comment:Fisheye lenses have always been interesting, they can make some really great shots, but most of the time you would be better off using a Ultra Wide Angle rectilinear lens.
I chose to buy the Sigma fisheye because it has a maximum reproduction ratio of 0.3X, to give you an idea how large that actually is, some lenses are marked "macro" at 0.5X maximum magnification.
First time using it to take Wide angle macro shots was quite disappointing, the distortion was really distracting, and the reproduction ration although really large wasn't quite large enough.
The solution came quite simple, a 60 Euro Kenko 1.4x TC, since the TC magnifies the center portion of the image, the distortion wasn't as massive, and the maximum magnification became 0.42X.
Using this combination the results were vastly improved, the distortion, although still present isn't as distracting, the sharpness is really good starting from F/4 all the way to F/11.
Because the front element is exposed the flare control is not that great, and you really have to be careful when working close to the MFD.

On the A200 it was really difficult to use, since the camera didn't have live-view and the focusing was sub par, I mostly used the full time manual focusing thanks to the HSM motor. on the A77II with it's versatile live-view the lens is much easier to use and the focusing is improved.

I use this lens only for Wide angle macro shots, where the distortion it offers gives the photos a "bug eye view" feeling.
For anything else where a UWA is needed I prefer the Samyang 12mm, which is just as sharp, smaller, and if needed you can add filters.
