The Sigma AF 100-300mm f/4 EX HSM DG is one of the most impressive Sigma lenses tested to date. It is able to deliver a near-flawless performance with great resolution figures, low vignetting, low distortions, low CAs and a very decent bokeh (albeit slightly underdeveloped regarding the moderate max. aperture unless your main subject is fairly close). It works reasonably well with the Sigma AF 1.4x DG EX converter but there’s no free lunch here for obvious reasons. The Sigma is quite a monster of a lens but the combination of speed and focal length range simply takes its toll regarding size and weight requirements. The build quality is exceptionally high and combined with the snappy AF it was a joy to use the lens in the field. READ FULL REVIEW

The AF 100-300mm f/4 EX HSM is the most impressive Sigma lens tested to date. It is capable to deliver a near flawless performance with great resolution figures, low vignetting, low distortions, low CAs and as a nice whipped cream on top the build quality feels just right. It also mates pretty well with the Canon EF 1.4x II converter at costs of relatively high CAs and a somewhat lower but still high resolution. All in all … highly recommended! READ FULL REVIEW

  1. My favorite lens (so far). Looking for a good lens for a safari trip in 2007 I found the review and decided to buy one. It was perfect for the purpose and I have never regretted that I bought it. It’s sharp, very sharp, at all zoom settings. Perhaps not wide open at f/4, but stop it down to f/6.3 or more and you will get exceptionally sharp pictures. AF is silent and fast and it’s not heavier than being very useful for hand held pictures of flying objects – like birds etc. It’s built like a tank and will take a lot of beating. Put it on a monopod and you don’t really need OS. I also bought a TC1.4 to use with it but I’m not satisfied with the picture quality with the extender added. I now use it mostly for ‘shooting’ birds and animals. Also great for portraits. Fantastic lens that I can recommend without hesitation.
