Notes on Sigma 8mm f/3.5 EX DG Circular Fisheye ...- This Sigma lens is like a working piece of art. The build quality is high, the images are bright and sharp with excellent color saturation. I use mine to shoot full-screen 360 by 180 panoramas and the results are breathtaking! The best part is that this lens costs 1/3 to 1/4 of what the Canon 8mm lens costs. It's an awesome deal, no matter what way you look at it. The Sigma 8mm is definitely a professional grade lens.

Summary for Sigma 8mm f/3.5 EX DG Circular Fisheye ...- Fun
Notes on Sigma 8mm f/3.5 EX DG Circular Fisheye ...- Very fun lens! Good color, sharp, great distortion. I have a Canon Rebel XTi and with the 1.6x crop i needed something with a lot of distortion. The vignetting can be pretty annoying because you have to edit every photo but it's no big deal. This is a good lens and I normally dislike Sigma.

Summary for Sigma 8mm f/3.5 EX DG Circular Fisheye ...- Smaller image than you think
Notes on Sigma 8mm f/3.5 EX DG Circular Fisheye ...- Good quality but on my Canon 5D, the circular image is pretty small. I was hoping it would be snug top-to-bottom to maximize pixel count. the lens may have been made for a 1.3 or 1.6 crop factor DSLR. That said, it's a HUGE improvement from my Nikon FC-E8 on a 995.

Notes on Sigma 8mm f/3.5 EX DG Circular Fisheye ...- I think this is a great lens for expanding your view of the surrounding environment. This Sigma Lens works flawlessly in conjunction with my Canon Rebel, I am looking forward to the time I use it with my soon to be purchased Canon mark 3 which has a larger sensor. The focus is sharp, the color true, and the price was right.
