Review on 🌊 Sigma 10-20mm f/3.5 EX DC HSM ELD SLD Lens for Nikon DSLR Cameras: Ultra-wide angle mastery! by Richard Gallagher

So I made the mistake of buying this lens for my full frame Canon 5D Mark II camera. My other lens is a 24-70mm zoom and I needed a wider angle for indoor shots. From the start I liked the wide angle with low distortion, but I did notice vignetting and realized I had ordered the wrong lens. POOH! After doing a little research, I found that a similar lens for my camera would cost at least three times as much as this one. I thought I'd have to return this one and just put up with the fact that I always have to lean against the wall indoors! Then in post-processing I saw that I could get a good shot at 13mm before the vignettes appeared. My decision is to keep the lens due to the cheap price and the fact that I can now shoot 13-20mm with no problems! That covers exactly the focal length range I needed, so a lucky coincidence!
