I bought this lens about 8 years ago and use it mainly for nature and wildlife. It's sharp and stays sharp even with the 1.4 Sigma teleconverter. It looses a little bit with the 2.0 Sigma teleconverter but if you're able to shoot at f8 it's pretty darn sharp.

Sold my AF Nikkor 300f4 EDIF and was looking for a 300f2.8 lens when a friend notified me that a photography store on eBay was going out of business and selling Sigma long lenses for good prices so I bid $1825 and to my surprise I won the auction and received a Sigma USA waranteed lens.

    Fast and quiet and works quite well with Sigma's teleconverters.

    Only weakness is the tripod collar could be a little longer like the one on the Sigma 120-300. My preference is for the center of gravity to be a little more towards the front rather than the rear of the lens.

I have used the lens for three soccer matches since I got it and I am so far pleased with the image quality. I like the weight and auto focus tracking.

I wanted a telephoto lens with an f/2.8 capability and planned to extend the range with teleconverters mostly for nature/wildlife photography. I read reviews and watched YouTube videos (not many available due to the newness of this product) and it sounded great.

I used this lens on a wildlife trip to India. It was lighter than the similar Nikon lens and autofocused consistently with the Sigma 2x tele-converter attached (which is not true with my Nikon lens/2X teleconverter). I was very unhappy with the lack of sharpness, though.

I photograph wildlife primarly. The 2.8 F stops really has impproved the clarity of my photos and ability to shoot in liwer light circumstances.

Can't compare it to one of nikon's or canon's 300mm f2.8's, but it focuses fast, works well, and is a cheaper alternative to the more expensive options

I mainly use the Sigma 300mm lens for sports and wildlife shoots, although the bokeh makes it nice for tight portraiture shots as well. The quality rivals that of it's Canon counterpart at nearly half the investment which makes it very attractive to the budget-conscience photographer like myself.

I was skeptical about getting this lens but I decided to bite the bullet and see how it performed. To say I was blown away by the results would be an understatement. Image quality has been on par with both the Canon and Nikon equivalents.

Strong construction; very durable and sleek. Great clarity and focus. Only con is its heavy weight, so I would not recommend this lens to someone who isn't using it on a tripod. My main purpose for using this lens is for surf photography so I will always be using a tripod which negates the weight...
