LensRentals.com has posted their first look of the brand new Sigma 20mm f/1.4 DG Art series lens with a series of MTF curve tests.
With a wide-angle, wide-aperture prime lens, MTF is probably not the main consideration in whether you buy the lens or not. Theses lenses are used for different things by different photographers and bokeh, handling, vignetting, and dozens of other things I don't test for will make a bigger difference in whether you like the lens, rather than simply how sharp it is.
Everyone's first comment seems to be, “Well, I don't need a 20mm f/1.4 lens”. I said that myself. But then I realized, well, I've never had the opportunity to use a sharp 20mm f/1.4 lens before, because there's never been one . Will I like it? I have no idea. But I think I'll at least check it out, it might be fun. Especially at this price point.
But the geek in me, at least, is totally impressed. Wider, faster, sharper, cheaper. What's not to be impressed by? Read the story
