Reviews and Problems with Sigma 4.5mm F2.8 EX DC CIRCULAR FISHEYE HSM
Showing 1-10 of 23
Not recommended for 360 x 180 Panoramas :(

Summary: This lens captures extremely blurry photos and the depth of field is horrible. It is just impossible to have whole frame in focus (Or may be its an issue with the piece I received). I have just raised a return request to seller.
Summary: I picked this one out for my Sony Alpha 77 from all the other options, because this one has autofocus. I take a lot of self portraits and I needed autofocus for that purpose. It is exactly what I expected, works well in low light, sufficiently sharp, and fun to use.
Summary: Perhaps I got a bad lens, but this lens is far too soft for my purposes. Remember, 180 degrees of vision is squeezed into a circle within the rectangular canvas of your camera's sensor (hence circular fisheye).
Summary: This product is great except cost. If you don't mind spending around $900 then this lense is for you!!!! If you are budget minded you could get a manual lense far cheaper that produces the same great pics. The only reason for 4 stars is cost everything else is wonderful.
Summary: Combined with Nodal Ninja rotating tripod heads, I'm using this lens to produce equirectangular 360deg x 180deg panoramas. Six shots in 60deg increments work perfectly when stitched with Hugin or AutoPano.
