Review on Sigma 8mm f/3.5 EX DG Circular Fisheye Lens for Canon SLR Cameras: Wide-Angle Distortion at its Best by Michelle Wright

I've been using the lens for about 6 months now and of course I handle the lens very carefully, especially when removing the lens front cap. I immediately noticed that the front lens adapter ring is a bit loose and tends to slip off, "just doesn't fit" and has a thin metal rim. I'm a professional photographer and use the lens on a daily basis and this eventually happened, I took the lens out of my bag and the thin edge on the front adapter ring that the front lens cap snaps onto slipped off and really scratched the front. Lens. I would give the lens 5 stars but I feel the front adapter ring needs a rework, the edges are too thin. I can't be the first photographer to have this happen. Be extra careful when removing the lens cap and front. Ring. . I want to give this product 5 stars but I can't right now because I need to buy a new lens. That wouldn't have happened if everything had been a little tighter. Be careful.
