comment:I've been making some Greentoe offers for a few full-frame E-mount lenses, and this was the first one completed. I haven't seen many reviews comparing these Tamrons to the smaller, cheaper Samyangs. I am fairly happy with my current copy of the Samyang AF 24mm F2.8. This lens is twice as heavy and at least twice the size of the Samyang. Tamron seems to have standardized on the 67 mm filter size. The price was slashed to $199 in early 2021. "This product is developed, manufactured and sold based on the specifications of E-mount which was disclosed by Sony Corporation under the license agreement with Sony Corporation." "MADE IN VIETNAM"

The body material looks similar to the Sony FE 50 F1.8. The plastic focus grip feels good. The OSD motor is quieter than the Sony, but it is still fairly audible--similar to the 18-135 SAM. The AF is slow like the FE 50mm F1.8.

This lens has a wider angle-of-view than my other 24mm lenses, even after Distortion Compensation. It has a lot of barrel distortion--more than the FE 28 F2. The Tamron supplied Lens Compensation corrects it fine in-camera or in Capture One. It has more focus breathing than the Samyang. The angle-of-view decreases with close focus.

It has similar directional glow wide-open as the Samyang AF 24mm F2.8 probably indicating some decentering. I sent the lens to Tamron warranty repair describing this issue, but it came back unimproved. It does have slightly better midfield sharpness and better contrast than the Samyang.

The main photo here here shows the lens at minimum focus distance. The front element is more recessed at infinity, and even more recessed when powered off. There is a substantial gap between the moving front section and stationary outer barrel. I wouldn't trust this lens with any moisture.

This uses the same HF050 petal hood as the 20mm. The hood bayonet is very similar to the ones on the SP F1.8 USD primes. Tamron has used 67 mm filter thread at least as far back as their 35-105mm F2.8 in 1992, but I prefer smaller, lighter lenses.

Tamron claims that firmware updates can be done through the camera body, but no updates have become available.

The smaller Samyang is a much better choice for video.
