Resolution figures and comparisons [Compared with Tamron SP 35mm f/1.4, Sony 35mm f/1.8 and others] The Sony 24mm f/1.4 GM was as expected. It’s the best 24mm on the market for any brand and it’s priced reasonably for what it is.
Excellent sharpness, extremely well-controlled distortion, chromatic aberration, and special attention to sagittal flare - what's not to like in this lens? Perhaps the only test results worthy of note is somewhat high corner shading, and in the days of Lightroom, you can dial in some brightness to the corners to correct this if it's even a problem. Overall, the Sony FE 24mm f/1.4 GM is an amazing full-frame lens.
It performs impeccably and at a price level that is competitive with Canon and very much less than Nikon. There are third-party alternatives that are also very good indeed, but for those seeking the manufacturer's own lenses then this offering is very, very attractive and an obvious Editor's Choice, the high expectations that we started out with having been totally met.
It is one of Sony’s best prime lenses. It combines features, optical performance, and good autofocus into an attractive, reasonably sized package. It is capable of producing a lot of fantastic images even shooting at F1.4 [...[ While the Tamron 24mm F2.8 is much, much cheaper ($349 USD), but isn’t in the same class for build, handling, or performance.
