We come to the feud of the 50s: the Canon 50mm f/1.2 L ($1619), Canon 50mm f/1.4 ($430), and lastly, the new Sigma 50mm f/1.4 Art lens ($949).
The 50mm range is a great range for almost everyone. It’s practical and versatile. Well, for a fixed lens. There are different tiers of 50mm’s and they all vary in performance.
Canon 50mm f1.4
The Canon 50mm f/1.4 is a great lens for the price, but the image quality and bokeh are a bit too hazy/soft. It’s not very usable wide open, unless you like the incredibly soft/glaze look.
Though the Canon 50L is a little sharper, but we noticed that the visual differences in image detail and sharpness started to equalize around f/4. Color rendition did remain and perform better for the 1.2 than the 1.4.
Sigma 50mm Art
Before, the Canon 50mm comparison would be just between the two, but Sigma has been introduced and they are slaying the game. The Sigma 50mm f/1.4 is sharp. Tack sharp. Even when shot wide open.
In terms of build quality, both the Canon 50mm f/1.2 and the Sigma lens are both great build quality. The 1.2 feels nice and has a smooth focus action. The Sigma is very sleek in design and next to the 1.2, it is skinnier and taller. The Canon 50mm f/1.4 doesn’t have a great build. It’s plastic-y and very flimsy.
Overall, the Sigma out-performs both lenses (even when the L lens is a 1.2-it’s barely noticeable). It is sharp, great for low-lit situations and fits in your hand much better. Price wise, the Sigma would be the best investment. You are getting Zeiss Otus performance, but for a much better price. You can check out these lenses by clicking here
