Samyang has just announced a new AF 24mm f1.8 FE full-frame lens for Sony mirrorless cameras that is optimized for astrophotography.

At just 230g and only 71.5mm in length, the new 24mm is part of the company’s “tiny lens” segment. Furthermore, the lightweight form factor will be embraced by many, particularly those, who need to pack light. Also, the lens sports a matte finish, with laser-engraved text providing enhanced readability.

You can also explore the Samyang AF 35mm f1.8 FE lens here.

In addition, the lens features weather sealing in 5 places to protect from the elements – mainly dust, light rain and snow.

Fast and Quiet AF for Astro Photography and Video

According to Samyang, their latest AF 24mm F1.8 FE features the latest STM (stepping Motor). This means makes it possible for a larger and heavier focus lens group to be controlled more quietly and precisely, providing superb image quality in both photo and video.

Nevertheless, even though many will use this lens for astrophotography, nothing stops you from getting great video results on your gimbal and filming music videos and other non-astro stuff. 


Focus Hold Button

Moreover, the new lens also features a focus-hold button. When you press and hold this button, it will keep the lens locked to that focusing distance.

Furthermore, the user can also assign other desired functions to the focus hold button through the menu setting on the camera body.

Custom Mode with LED Indicator

Arguably the big feature in the new Samyang AF 24mm f1.8 is a new function called “Custom Mode”, with an “LED indicator” for astrophotography. The “Custom Mode” can be operated through the new Focus Hold button. 

Furthermore, this function allows you to automatically move the focus directly to infinity, by clicking the button when entering the Custom Mode.

Since the factory default value may differ very slightly on each camera body, this is a convenient function that allows you to tune, save and use the precise infinity focus value, according to your own camera body.

If the focus value set through the LED indicator does not match, it will be shown with a red LED. If you then click the button, your focus value will automatically adjust to the saved value, changing the LED to green.

For astrophotography enthusiasts, this is an extremely useful function for those who need to spend long periods in darkness, with confidence that their lens is set at infinity.

Advanced Optical Formula

Samyang’s latest optical technology allows this large aperture wide-angle prime lens to achieve stunning corner-to-corner resolution, even at its maximum f/1.8 setting.

The lens’ optical formula encompasses a whopping 11 elements arranged in 8 groups, with 7 special elements. These special elements include two aspherical, 3 high refractive, and 2 extra-low dispersion elements. The inclusion of these makes it possible for photographers to achieve stellar images with minimised spherical aberration and coma.

The wide angle lens has an angle of view of 83.7 degrees and a short minimum focusing distance of 0.19m. This allows photographers to take photos in a wide range of environments, not limited to landscape, astrophotography, interiors and more.

Pricing and Availability

B&H Photo/Video has the new Samyang AF 24mmf 1.8 FE available to pre-order for $499 and listed as coming soon. Our guess would be this lens should be shipping sometime later in April or May.
