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
