Without a doubt, the 24mm f/1.4 GM lens is one of Sony’s finest optical achievements, and for me, it represents a turning point in their lens design process. Every FE lens that launched after this lens showed signs of a significant improvement in optical design and autofocus speed. In fact, when this lens launched, it was one of the things that finally grabbed my attention and set me on a path to move from Canon to Sony for my primary work setup.
A full review will be forthcoming, but in the meantime please enjoy this gallery of images. As you can see, this is a very small lens for a wide-angle f/1.4 prime.
Compared to the Sony FE 20mm f/1.8 G
The Sony 20mm f/1.8 G is very similar in look to the 24mm GM. The 20mm G lens shard the same styling, aperture ring, de-click switch and customizable button. The 24mm GM is a little larger and a little heavier and comes with a metal filter thread where the cheaper 20mm G lens has a plastic thread. The 24mm GM also comes with a much nicer lens case and a slightly larger and more robust feeling lens hood. Personally, I own both of these lenses.
