The Sony FE 50mm f/1.4 GM looks like a great lens, but how does it compare to the Sigma 50mm f/1.4 Art? DPRTV put together a video to help you decide which is best for you.

  • The Sony is smaller and lighter than the Sigma, with the Sony weighting 519g and the sigma weighing 670g
  • The Sony has a 67mm filter thread, and the Sigma has a 72mm filter thread
  • Both lenses have similar controls with aperture rings that can be clicked or de-clicked
  • Both lenses AF quickly, so it is a tie even though they didn’t make an apples-to-apples comparison
  • The Sigma lens will be limited to 15fps on Sony bodies, but the Sony is not
  • Sony maintains contrast but has ghosting, while the Sigma loses contrast and has less ghosting, so their flare resistance is similar
  • Both have some LoCA, but it is pretty much identical and well managed
  • Sigma has a little bit of cats eye bokeh with onion rings, while the Sony is cleaner
  • When you stop down to f/4 both lenses continue to have round bokeh, and the cat’s eye goes away with the Sigma
  • Sony G Master at f/1.4 is a lot sharper wide open, and both lenses have improved contrast stopping down that makes them similar
  • With a low-resolution body both lenses are probably similar enough, but if you are shooting a high-resolution body the Sony is the lens to go for
  • The Sony is more expensive, so you might want to save your money if you’re shooting a lower-megapixel camera
