I'm just starting to attempting night star photography. I have a 16-35 f/4 and a 8-15 f/2.8.
I am thinking about getting the 14mm f/2.8 Rokinon, but am wondering if I use my 8-15, would I be able to correct the fish eye affect using Photoshop or Lightroom? I don't know much about either program, but am willing to learn. Or is it easier to just buy the Rokinon? Its pretty inexpensive.
Check out this blog. He does amazing work and has done a lot of lens testing. He shows that that Rokinon performs better for this use (less coma) than the comparable Canon costing 4-5x more.

Thanks for the reference. I had no intention of buying another Canon lens, I am wondering if my current 8-15 f/2.8 after correction in photoshop, would be relatively as good as the Rokinon 14 f/2.8 sooc.
And if i go for the Rokinon, should I bother with the chip version or not?

Getting good focus in the dark is difficult. I the chip version can help with that, why not?

Dont really use autofocus for night sky photography, and the chip version is more money. :-)
Hello Janyce, I have a 16-28mm Lens I use set at 16mm f/2.8, and find it to be the widest angle I would want to use. I use lens correction in Lightroom and get some pretty good processing that way. The 8-15mm f/2.8 set to 15mm f/2.8 is the Lens I would use. I have had a Rokinon lens and wasn't very satisfied with it. Inexpensive gets inexpensive shots. I hope you don't mind me posting a shot I've taken.

That lens is manual focus and the chip gives you focus confirmation. If that's worth the extra $160 or so... nah.
Me? I get a good manual focus at dusk and use some blue painter's tape to lock it.

That's a very good technique Skylane.
