TTArtisan APS-C 10mm f/2.0 10mm

This cheap ultra-wide prime delivers sharp images and surprisingly close focusing for less than 200 bucks. But it's manual focus only and the stiff aperture ring annoys some shooters. If you can live without autofocus, it's a steal.

Optically, this lens is a surprise. At f/2, it's sharp across the frame with remarkably little distortion for such a wide angle. Our tests put it well above average for optical quality, and it really shines as a close-focus lens. You can get within 25 cm and capture subjects with a near-macro magnification, which is a neat trick for dramatic wide-angle close-ups. The downside? Manual focus accuracy can be hit or miss, especially at infinity. The focus ring is damped but doesn't feel precise enough for critical work, and the aperture ring is so stiff you'll need two fingers to turn it smoothly.

There's no exact match at this price. The Sony 10-18mm f/4 OSS offers autofocus and zoom but costs several times more and loses a stop of light. The manual Rokinon 12mm f/2 is a close alternative with a slightly narrower view but better focus feel. If you crave autofocus and versatility, the Viltrox AF 35mm f/1.7 Z is a completely different beast but will serve you better for everyday shooting. For dedicated wide-angle work on a budget, the TTArtisan is hard to beat.

The price range on this lens is absurd, from $169 to over $3,000. Ignore the fantasy numbers. At the low end, it's a screaming deal for an all-metal ultra-wide prime that delivers real optical punch. Even if you pay a bit more, you're still getting a lens that punches above its weight in image quality, provided you're okay with manual focus.

The TTArtisan 10mm f/2 is a manual focus prime for Sony E-mount APS-C cameras that punches way above its price. With a fast aperture, solid metal construction, and a field of view that's perfect for wide landscapes and tight interiors, it's a tempting option for shooters on a budget. It even focuses close enough to dabble in macro-style shots, which is rare for this focal length. But you'll need to be comfortable with full manual control, no EXIF data, and a few handling quirks. The price spread for this lens is comically wide, ranging from about $169 to over $3,100. Obviously, you should ignore any listing above $300. When you find it at the lower end, the value proposition is almost impossible to beat for an ultra-wide prime with this image quality.

If you need fast, reliable autofocus for street photography, video, or events, skip this. The lack of EXIF data and the quirky focus ring will drive you nuts. Videographers who rely on smooth aperture changes should also look elsewhere because that ring is anything but smooth.

Photographers who enjoy manual focus and want a wide, fast prime for landscapes, interiors, or creative close-ups will find a lot to love here. The optical quality and build are impressive for the money. However, the stiff aperture ring and finicky focus accuracy mean you'll need patience. If you're willing to work around those quirks, this lens is a fantastic entry into ultra-wide photography.
