Samyang's compact 45mm f/1.8 built for Sony mirrorless shooters.

The 45mm focal length sits right at natural human perspective, and Samyang's AF 45mm f/1.8 FE leans into that with an optical formula built around real-world shooting. Two aspherical elements keep spherical aberration in check across the frame, while a single ED element handles chromatic fringing, the kind that shows up at f/1.8 along high-contrast edges. Ultra Multi-Coating cuts flare and ghosting when you're shooting into light, which matters at a focal length people actually use for available-light work.

The linear STM autofocus motor is the right choice for a lens like this. It's quick and quiet, which makes it usable for video without the motor chatter that plagues older designs. Manual focus override is available when you want it. The 49mm filter thread keeps your investment in filters modest. For what it is, a native Sony E-mount prime at f/1.8 in a compact body, the optical engineering is thoughtfully matched to how photographers actually shoot.

Who It's For

Street photographers get a focal length that reads naturally in the frame, a fast f/1.8 aperture for low-light work, and a small form factor that doesn't draw attention. Videographers working on Sony Alpha bodies will appreciate the quiet linear STM motor, which won't intrude on recorded audio during pulls. Portrait shooters who find 50mm slightly too tight and 35mm too wide will find 45mm hits an useful middle ground, with the ED element keeping color fringing off skin tones. Travel photographers prioritize pack size, and the compact build with a 49mm filter thread makes this easy to carry daily.

FAQ

What's the autofocus performance like on the Samyang 45mm f/1.8 FE?
The linear STM motor is quick and quiet, which makes it solid for both stills and video work without the motor noise you get from older AF designs. Manual focus override is available when you need it.
How does this lens handle chromatic aberration at f/1.8?
A single ED element is built into the optical formula specifically to control chromatic fringing - the color separation that typically shows up at wide apertures along high-contrast edges.
Is this lens good for available-light shooting?
Yes. The f/1.8 aperture and Ultra Multi-Coating work together to handle flare and ghosting when you're shooting into light, which matters for the kind of natural-light work where 45mm gets used.
What filter size does this lens use?
The filter thread is 49mm, which keeps your investment in filters modest if you're building a kit.
How compact is the AF 45mm f/1.8 compared to other 45mm primes?
Samyang designed this lens around a compact form factor - the two aspherical elements and ED element are arranged to keep the physical size down while maintaining optical performance at f/1.8.
Can I use this lens for video on Sony E-mount cameras?
Yes. The linear STM motor is quiet enough for video work, and manual focus override gives you control when you need it during recording.
