I just got this new lens, thought I would open a new thread.

I already own the Samyang 14mm f/2.8 but I find it:
- a little too wide
- distortion is very hard to correct in post

I was tempted to buy the Sigma 20mm f/1.4 Art but it is too heavy and too big for my needs.
I thought long and hard about buying the Samyang 24mm f/1.4 but the extra 4mm do make quite a difference and the new Samyang uses a 7-blade aperture which produces nice 14-point stars.

I tried the 20/1.8 in a store and that copy was super sharp from corner to corner, wide open. I bought it straight away and so far I am blown away.
At f/1.8, it is almost as sharp as my Sigma 35mm f/1.4 Art.
The bokeh isn't very pronounced but the lens focuses very close and the background blur is pleasing.
Distortion is well controlled and unlike the 14mm, it is easy to correct in Lightroom.

Here is a quick shot, wide open, flying over London.

More pictures. Sorry, they are all aviation-related.

Here is the Milky Way as seen from 37,000 feet. The camera was on a soft dark piece of cloth.

Yes, on a smooth flight I can get 20 second exposures with the camera pointing in the direction of flight. It's sharp enough for web uploads.
If you search on Youtube "Live from the Flight Deck", you'll find a popular video I uploaded in late 2015 with a few of these timelapses, made up of long exposures with a camera in the cockpit.

Here is a picture taken wide open (f1.8).
It's an unusual, almost bizarre effect.
The airplane is a Boeing 737NG.

Mounted on a Canon 6D
20mm | f/1.8 | 6sec | ISO3200

I took this picture from the cockpit of an airliner.
The green and red trails are the navigation light of a crossing airplane 1,000 feet above us.

Very little coma wide open, impressive performance from this lens.

Thanks for making this thread I just found out about this lens the other day and am considering giving it a try. I enjoy the 20mm focal length and had the canon version for a while but found the image quality lacking in such an old lens.

Oops 2nd edit: Does this lens have the AE chip does it record the metadata or not?

Unfortunately no, no chip and no metadata recorded.

Here is a picture taken at f/5.6 (from what I remember). 20mm is the perfect focal length for that kind of shots.

Two photos to show what you can get at 20mm.
It's not too wide that the picture is distorded, but wide enough to get a lot in the frame.

The Strait of Gibraltar at seen from 36,000 feet, flying over Tangier, Morocco. The Spanish city of Ceuta, on the Moroccan side, and Algeciras on mainland Spain can be seen.
Gibraltar is below the clouds.

It is part of the name of the lens.
