The vignetting on this lens was kind of strong, especially at the widest apertures that are almost always used for astrophotography.Īt f/2, the edges appeared about one stop darker than the middle of the frame. Sony A7III + Sony 24mm f/1.4 GM | 15sec at f/2.Īuto focus is also very fast, silent, and smooth with a manual focus override available at any time (it almost always nails the focus so I don’t use this feature). This lens also has a moisture seal and a thin gasket at the lens mount, similar to the Sony 16-35mm f/2.8 above. It feels quite lightweight for the quality, which is typical with full frame Sony lens options – Sony FE camera lenses are often marginally lighter than other manufacturer equivalents. I’m not sure I find this all that useful but it could be interesting to have a more analog feel when using it.Īt 445 grams, it is about 200 grams lighter than the Canon DSLR equivalent. The manual aperture ring has a classic quality to it and allows you to get a more tactile control (but can be de-clicked for silent operation). I think it lives up to the expectations of the GM series and also has some unique features. It’s the eighth lens in the G-Master series and is supposed to be the highest quality of the lenses Sony makes. (See other lenses that work well with Sony a7 series cameras here.) This lens balances nicely when paired with the Sony A7III and has a sturdy feel. The recently released (late 2018) Sony 24mm f/1.4 GM lens is another top-quality lens for astrophotography from Sony. Sharpness: Great! // Aberration: Minimal // Vignette: Minimal Overall, I’d rank this lens number two out of the four lenses in this post. If you want to go wider than 16mm, the only other option is the Sony 14mm f/1.8 which is a great lens but doesn’t offer the flexibility of the 16-35mm zoom. The vignette is mostly correctable in Lightroom but it still appears slightly darker around the edges. (On an APS-C body like the Sony a6400 ( review), you’d definitely need to use a lower ISO and steady your shot with a tripod.) Having a max aperture of f/2.8 is a bit limiting when it comes to astrophotography, but you can compensate for this with a good high ISO full frame camera like the Sony A7III. Other drawbacks for this lens are the high price tag, that the maximum aperture is only f/2.8, and that it has a slightly stronger vignette compared to the others. All my astrophotography is done using manual focus, but having autofocus makes the lens much more versatile for everyday shooting.
