I have been using this lens for a few weeks now and I am very impressed by its performance and quality. It is a fast, sharp, and compact wide-angle prime lens that delivers stunning images on the sony a7III. The lens is very well built, with a metal barrel, a rubberized focus ring, and a manual aperture ring that can be de-clicked for smooth transitions. It also has a focus hold button, a focus mode switch, and a lockable lens hood. The lens is weather-sealed and dust-resistant, which is great for outdoor shooting. The autofocus is fast, silent, and accurate, thanks to the direct drive SSM (Super Sonic wave Motor) system. The lens works well with the sony a7III’s eye AF and tracking modes, and I had no issues with focus hunting or missed shots. The manual focus is also smooth and precise, with a linear response and a good amount of resistance. The image quality is superb, with excellent sharpness, contrast, and color rendition. The lens resolves a lot of detail on the 24-megapixel sensor of the sony a7III, even at the widest aperture of f/1.4. The lens also has very low distortion, chromatic aberration, and coma, thanks to the advanced optical design that features two XA (extreme aspherical) elements, three ED (extra-low dispersion) elements, and a Nano AR coating. The lens produces beautiful bokeh, with smooth and circular out-of-focus highlights, thanks to the 11-blade circular aperture. The lens also has a very shallow depth of field at f/1.4, which allows for creative isolation of the subject from the background. The lens also handles flare and ghosting very well, even when shooting against the sun or bright lights. The lens is very versatile, as it can be used for a variety of genres, such as landscapes, street, portraits, weddings, astrophotography, and more. The 24mm focal length is wide enough to capture a lot of the scene, but not too wide to cause distortion or perspective issues. The f/1.4 aperture is ideal for low-light situations, as well as for creating a dramatic effect with the background blur. The lens is also very compact and lightweight, weighing only 445 g (0.98 lb), which makes it easy to carry around and balance on the sony a7III. The lens is much smaller and lighter than the Sigma 24mm F1.4 Art lens, which weighs 665 g (1.47 lb) and is 90 mm (3.55 in) long, compared to the Sony’s 75.4 mm (2.97 in) length1. The only downside of this lens is the high price, which is $1,398 at the time of writing2. This is a premium lens that comes with a premium price tag, but I think it is worth it for the quality and performance that it delivers. This is one of the best wide-angle prime lenses that I have ever used, and I highly recommend it to anyone who owns a sony a7III or any other full-frame Sony mirrorless camera.... Read More  Hide

I use this for astro a lot. I use it on my full frame camera and switch to ASP-C mode for street, giving me an about 38mm equivalency. Excellent Bokeh. great colors and always sharp as a whistle.

Initially I was extremely excited to get my hands on this lens having read the various reviews and seeing footage/images taken using the 24mm 1.4 GM. However this lens, and it may be that I received a faulty lens from Sony, produces an unbearable rattling noise as you change aperture. I've tried adjusting it both manually and automatically yet this noise is persistent. After searching the issue up online I was directed to download and install both firmware updates for my Sony A7RIII body and 24mm 1.4 GM lens, which I did. But to no avail, the noise was persistent even after putting the Aperture to silent priority mode. I'm not sure if this is normal for this lens as none of my other lenses have this issue and work just fine. This is my first Sony lens, let alone my first G Master lens, purchase and I'm actually really disappointing. I would love to hear some input from anyone else on this matter/issue. I would especially value a response from a Sony representative as to whether this is normal for such an expensive lens. I've attached a video below of the issue. (Note: The camera is in Silent priority mode)... Read More  Hide

Fix old firmware issues first so that products of this kind might be usable.
