comment:The first copy I received was not sharp wide-open, so it was returned to the eBay seller. The second copy purchased from Adorama is much sharper but still has a directional glow on high contrast edges wide-open. It also has more lateral CA on the right side than the left side. "MADE IN KOREA"

This is the best ultra-wide I've owned so far. I enjoyed their 12mm F2 on APS-C, and have been looking for a replacement for a while. The Zeiss Batis was more than I wanted to spend.

The image quality and operation of this lens are similar to their 24mm F2.8, but it is closer in size to their 45mm F1.8 and the Sony FE 28mm F2. It is smaller and lighter than the Batis and the Tamron F2.8 prime trio. The focal length is a just a bit wider than the Sigma 19mm F2.8 DN Art. It has better corner performance on APS-C than that lens and much better AF.

The blue color shift towards the edges reminds me of the Sony DT 18-55 SAM kit zooms at the wide end. The Minolta AF 20mm F2.8 and Sony E 20mm F2.8 also do this a lesser amount.

Capture One 12 misidentifies it as the Zeiss Batis 2.8/18, but exiftool shows Lens Model as SAMYANG AF 18mm F2.8.

The 58 mm filter thread diameter is unique in FE lenses, but it is a common on affordable Canon lenses.

The molded, zippered clamshell case has no flat sides making it unstable for storage on hard surfaces. For some reason the zipper was run along the length of the case instead of around the diameter like the similar case included with the 24/2.8 and 35/2.8. The same case is also included with their 45mm F1.8.
