Test of Samyang 135 f2

[OzEclipse (Joe Cali)]

Hi all,

I just recently purchased a Samyang 135 f2. I did some tripod shots that looked promising. Last night, I was doing something else on another scope but set up and put the 135 on a Losmandy Starlapse tracker, unguided and shot with

• aperture wide open 135mm @ f2
• 12 x 60s subs driven by intervaloimeter
• Pentax K1 at ISO 1000
• Median averaged in Photoshop.

The tracking isn't perfect but it looks like the lens is pretty good right to the corners. When I put it on a better quality mount, I'll post some more definitive results.

I bought the lens when it was on a . decent discount a couple of months ago.

Looks good Joe

I'm impressed that it's good to the corners on a full frame when wide open.

Great result, Joe!

That looks really good Joe. Nice pic.

I've had some very pleasing results with mine but I've noticed it also seems very sensitive to focus.

A lovely image. I have read several times this is a good lens for astro.
