Re: Needing help to decide which of these lenses is my best option
There's a few here that use a lens for astrophotography. I'm sure you'll get lots of advice.
Welcome to the forum.

Re: Needing help to decide which of these lenses is my best option
If you go for the Samyang 14, you will then get 300/14 then you can go all the way up to 22 seconds of exposure before the trails become evident.
Good luck with whichever lens you choose.

Re: Needing help to decide which of these lenses is my best option
I have only taken a few hundred images, mostly of an indoor baby shower for my daughter. I was able to capture about 30 good images, the rest so-so, and I attribute that to my ability as a beginner in digital photography. Sadly, I have not tried any astrophotography yet. I know a faster lens is always better for the night sky, but the faster and newer the lens, the more expensive it is. I decided to keep my purchases on the cheaper side. You can always buy better lenses as your skills get better. I have heard the Samyang/Rokinon lenses are very good for the price.

Re: Needing help to decide which of these lenses is my best option
You didn't mention anything about having a tracker or mount so I'm assuming you are just talking about using this on a fixed tripod. If that is true, that will rule out anything tighter than 24mm or you will get star trailing very quickly. So now you are down to just 11 choices. Now, cut all of the zoom lenses. They are generally not great for astrophotography. That whittles your list down to only 7 choices. Next lenses to cut are anything slower than f2.0 and that gives you only the Samyang 16mm
Personally, my choice would be the Samyang 24mm T/1.5 VDSLR ED AS IF UMC II. Stop it down to f2 or f2.8 and you have a great lens.
