Summary
The new TTArtisan AF 24mm f/3.8 Mini launches at $99 internationally, weighs just 57 grams, and brings autofocus to a full-frame pancake only 16mm long.
Announced on October 13, 2026 for Sony E-mount, it targets photographers who want to carry a camera without a bulky lens. But its remarkably compact design comes with trade-offs that fundamentally affect how you shoot.
Small enough to leave on the camera
The lens measures roughly 60mm across and 16mm long, weighing around 57g. It covers full frame and gives an 84-degree angle of view. At 24mm, streets, buildings, landscapes and environmental portraits fit naturally into the frame.
Sony E-mount also allows use on APS-C cameras, producing a field of view equivalent to approximately 36mm on full frame. That makes the lens a more conventional everyday focal length on a smaller sensor, while retaining its main strength: portability.
A fixed f/3.8 aperture and autofocus only
F/3.8 is a fixed aperture, not merely the widest available setting. You cannot stop down to f/5.6 or f/8 for greater depth of field, or open it up in low light. Exposure control therefore relies on shutter speed and ISO; bright conditions may call for faster shutters.
A VCM motor provides autofocus, including face and eye detection when supported by the camera. There is no manual focusing ring or manual-focus mode. If AF struggles, you cannot turn a ring to take over. It is a meaningful limitation for deliberate focus pulls in video.
The lens also lacks a threaded filter mount, an important consideration for landscape photographers. Its slim build trades away familiar controls and accessories.
Optics and built-in lens protection
Six optical elements are arranged in six groups, including two ED and two aspherical elements. Minimum focus distance is 0.3m, allowing close subjects with some of their environment. These are manufacturer specifications, not independent tests of sharpness or distortion.
Instead of a separate front cap, a small lever operates a built-in mechanical protective barrier over the front glass. The lens also has a metal mount and a USB-C port for firmware updates. The barrier must be opened before taking a photograph.
What the official sample photographs show
The four supplied examples focus on street scenes and urban architecture. They illustrate the 24mm field of view in natural light, but promotional image files alone cannot establish corner sharpness, flare resistance or autofocus reliability.
Price and availability
The international launch price is $99. TTArtisan Iberia lists the AF 24mm f/3.8 Mini for €109 and marks it as available on backorder. This does not establish confirmed stock or a separate retail price for Greece.
The stripped-back approach recalls the $99 AF 85mm f/1.8 Neo, which also gives up conventional manual controls, though it is a very different type of lens. More details are available on the official product page.
What we think
The appeal of this TTArtisan is not that it replaces a photographer’s main 24mm prime. It offers a different advantage: making the camera easier to bring along in the first place. For street photography, travel and everyday walks, a lens this compact can make a practical difference.
The fixed aperture is a bigger compromise than its attractive price might suggest. You cannot select f/8 for a landscape or f/2.8 as daylight fades. With no manual focusing option, you also have to rely on the autofocus system to put the plane of focus where you want it. These are fundamental limitations rather than quirks you can learn to work around completely.
We would see it as a lightweight specialist second lens, not the sole lens for demanding assignments or video work requiring precise manual focus pulls. At $99 it could make excellent sense for a particular kind of photographer, provided the compromises are understood before purchase.
Frequently asked questions
Can I adjust the aperture?
No. The lens always operates at f/3.8 and does not have an adjustable diaphragm.
Is manual focus available?
No. Focusing is handled by the VCM autofocus system, with no manual-focus option.
Does it work on Sony APS-C cameras?
Yes. On Sony E-mount APS-C bodies it gives a field of view equivalent to roughly 36mm on full frame.
