Friend of the site Dustin Abbott has completed his review of the brand new Sigma 150-600mm f/5-6.3 DG OS Sport lens.
Dustin initially wrote this lens off saying:
I had pretty much written off the new Sigma 150-600mm f/5-6.3 DG OS HSM SPORT lens before I reviewed it. I saw the specs (including the heavy weight and increased size over the Tamron 150-600 VC), and the MTF charts and early shots didn’t seem to be a lot better than the Tamron.
However, after using the Sigma, Dustin came away quite impressed by the mix of build quality, performance and value.
All in all I consider this lens to be a smashing success for Sigma. It has some shortcomings (its vignetting, particularly slow aperture, and heavy weight), but the tradeoff for that weight is a beautifully constructed lens that really feels like a match for some of Canon and Nikon’s best made lenses. It has great optical performance that is going to make a lot of photographers very happy with the images they bring home (this would be an amazing safari lens!) That focal length is really quite incredible, and the fact that you can use the lens wide open at all focal lengths without hesitation is very empowering. The price may seem high in comparison to the Tamron, but after using this lens I feel that the price is actually extremely reasonable for what you are getting, and would probably still be a decent value if it were $1000 more.
