Hi, Iam not sure if this is the right thread but I am looking for some help. I have a Pentax fs10 35mm and looking for a bayonet mount fisheye lens. What suggestions do u have on searching for this? I am new to the camera/photography world and am not even sure how to begin the search for this lens. Is there a specific name I should be searching for that is compatable with this camera model? Any help will be greatly appreciated.
Thank you,
Joanne

I assume you actually mean SF 10 , but anyway there are s verbal options. Pentax made a full frame 17mm fisheye for many years, but I believe only in Manual focus. They also made a 17-28mm fisheye zoom i think this is Auto focus.

You can also get a zenitar 16mm fisheye (likely the lowest price option, but not AF)

Sigma also makes some autofocus fisheye lenses, and samyang makes manual focus ultra wide lenses, which , although not fisheye have some barrel distortion

You would want a lens that has a "k-mount" bayonet mount. I suspect the F 17-28 fisheye zoom would be the easiest to located they come up quite frequently. See here: SMC Pentax-F 17-28mm F3.5-4.5 Fish-Eye Reviews - F Zoom Lenses - Pentax Lens Reviews & Lens Database

Other options mentioned above.
