Sony Adds Compact FE 24mm, 40mm, and 50mm Primes to G Series Lineup

Hot on the heels of its latest G Master lens, Sony has just announced three new compact primes in its G Series lineup: the FE 24mm f/2.8 G, FE 40mm f/2.5 G, and FE 50mm f/2.5 G. Adopting many of the advanced design features of their larger siblings, the trio delivers exceptional optical performance in a form factor perfect for everyday carry.

Although created for full-frame E-mount cameras (hence the FE designation), their compact build pairs nicely with APS-C models where the 24mm becomes 36mm, 40mm becomes 60mm, and 50mm becomes 75mm. Priority was given to making these lenses small, so that they won’t take up much space in your camera bag, and light, so they won’t weigh you down while shooting. Consequently, each lens measures only 1.8" in length and weighs between 5.7 and 6.1 ounces, depending on the model.

All of the lenses incorporate aspherical elements to combat aberration and distortions, as well as extra-low dispersion glass to reduce color fringing and chromatic aberration. A seven-bladed circular aperture helps achieve smooth, round bokeh. Complementing the versatile focal lengths of the new lenses are minimum focusing distances that benefit close-up capture: The 24mm allows you to get as close as 7.1" (manual focus) / 9.4" (autofocus), the 40mm can get 9.8" (MF) / 11" (AF), and the 50mm can focus as close as 12.2" (MF) / 13.8" (AF). Each lens features two linear motors to provide quick and responsive autofocusing for still capture, and quiet performance when recording video.

The physical design of the new lenses incorporates some of the most useful features of Sony’s top-tier lenses. The aperture ring can be adjusted in 1/3-stop increments, or de-clicked via a switch on the side of the lens barrel for video applications. An auto/manual focus mode switch is incorporated for moving quickly between focusing modes or fine-tuning focus. Finally, a customizable focus hold button can be used for its namesake or reassigned, based on user preference.

All of the lenses boast a sleek aluminum design that is dust and moisture resistant, adding to their appeal as everyday carry options. Settings are engraved into the lens barrel, presenting both an aesthetically pleasing touch as well as adding to the durability of the lens.

These look great and affordable. I would use the 40mm with an A7RIII for video but I have a question.

I have manual lenses with the aperture ring but how does this work on the new lens. What mode do I need to be in to use it and if I am in shutter priority, does the camera over ride the dial. I'm sure you know what I'm asking. I like fully manual for video but things like timelapse need to be controlled in other ways. 

In addition to f stop numbers the aperture ring will have an "A" which transfers control of aperture to the camera body.

If you wish to manually control the lens' aperture setting using the lens' built-in aperture ring, you would have to set the camera mode to either [M] Manual Mode or [A] Aperture-Priority Mode.  Aperture priority would allow you to manually set the lens' aperture and the camera would set the metered shutter speed, while Manual mode would allow you to manually control both aperture and shutter speed independently.  Shutter priority would not work when manually setting the lens' aperture as the camera would not be able to control the lens' aperture setting.  You would have to set the aperture dial on the lens to the red [A] Auto mode if you wish for the camera to control your aperture setting automatically in Shutter-Priority Mode, Program Automatic Mode, or any of the other automatic Scene modes that may be listed on your camera.
