Canon RF 7-14mm F2.8-3.5 L Fisheye STM

Reviewers treat it as a clear upgrade over the EF 8-15mm: wider, faster, lighter and better optically, especially toward the edge of the image. Sharpness holds up well out to the rim of the circle, and the aberrations that do appear at the extreme edge are well controlled and easy to correct. Autofocus is quick and hits most of the time in real event work, and the weather sealing held up in rain.

The drop-in slot for Canon's variable ND and polariser, the zoom lock with its APS-C setting and the removable hood are seen as practical additions. One review also sees the VR conversion as a real use, not a gimmick. The main objection is price: it costs more than the EF lens and much more than manual-focus fisheye zooms and primes from third-party makers, and it remains a niche lens.

Early owner reviews are positive. Buyers describe the build as excellent, the images as sharp and the lens as fun to use, and welcome a modern autofocus fisheye in the RF line.

One owner notes that a fisheye is an occasional lens, used when the effect is wanted rather than every day. The few reports so far are short and do not yet cover long-term use, flare or filter accessories.
