I wanted to give the new Sigma 24mm 1.4 DG HSM a go on Christmas Day and these were the results. I am a huge fan of Sigma and own their 50mm 1.4 DG HSM which I absolutely love. Sigma really stepped up their game when they released their art series lenses. The new 24mm has 15 glass elements in 11 groups, little to no chromatic aberration with the use of Low Dispersion glass. Sigma definitely takes the prize for the sharpest 24mm lens available for both Canon, Nikon, and Sigma shooters. Having used the 35mm 1.4 DG HSM (a must have and great price point) this new lens is a keeper especially when shooting interiors, landscapes, and product photography. So when you are looking for a great lens that gets you way more bang for the buck take a look at Sigma you won't be dissappointed. Cheers
