I am going on a night sky photography workshop. I just wanted to ask you all what is the best lens to use. I will be able to rent from Borrowlenses or lensrental to get what I need as my current wide angle only stops down to f4. I shoot canon so that has to be considered as some glass will not work without adapters that I do not want to use.
Why not contact your teacher???

The Rokinon 14mm f2.8 works nicely for Milky Way/nightscapes. If you are wanting anything to capture nebula, galaxies, planets you should consider a telescope. You can get some larger brighter nebula with a camera lens, but it gets much more difficult without a accurate tracking mount.
A good choice. Pick a lens with low coma.

If I were going to rent a lens for this, it would certainly NOT be a ZOOM !!
I would look at any of the 20/24mm f1.4's prime lenses - especially Sigma Art.

A good zoom is excellent choice. Esp the Sigma Art series. Both of these with Sigma Art 14-24.
I think a "kit" lens would be a poor choice based on other alternatives. But a good high quality zoom is priceless and gives great utility and choices.
I've been extremely happy with my 16-35/2.8 III and my Sigma 28/f1.4, they are both very sharp out to the edges and fairly coma free.
Canon lenses (zooms or primes) do not do well for night sky shots due to their poor coma. The higher quality 14mm Rokinon f/2.4 is quite good. As other have recommended, especially for the low end Rokinon, try a few lenses and pick the best. Check for sharpness and coma ('winged' stars in the corners). Most zooms are poor for night sky photography, the Nikon 14-24m being one exception. If you want a zoom for Canon, the Tamron 15-30mm is pretty good. Infinity focus requires you to focus on a bright star or distant light using a magnified image on the LCD screen. Then use gaffer's tape to make sure that the focus ring is not moved.

For the money, you can't beat a Rokinon 14 2.8.
Do you have full frame or crop Canon? Maybe I missed that earlier.

nice, love the first one. do you know what kind of exposure time you used?

I've used the Rokinon 14mm and 16mm EFS on my Canon 6D. They were adequate for a beginner as they displayed quite a bit of distortion in the corners but were very inexpensive. Rokinon makes a lens in that 14-16mm range that is more expensive than the others and is excellent. You can find it.
My Sigma Art 14-24 is tack sharp and I love that I can zoom a bit. I find I'm not limited to the 14mm and use the zoom quite a bit.
You should have at least f2.8 as with a f4 lens you will need to double something over a 2.8 lens - exposure or ISO. Doubling exposure will lead to trails while ISO introduces noise.
We were doing long exposures at low ISO for foreground one night and we all had 2.8 or faster and one person had a 4 lens. She kept slowing us down as our 3 minute exposure took her 6 mins. and so on.
So: Depending on your budget: get the less expensive Rokinon (totally manual which is ok as you will not be using AF at night), the better ROkinon, or a lens that you want to invest in.
If you choose the Rokinon - purchase 3 or 4 , test them, keep the sharpest one and return the others.
BTW - who you going with and where???

I am worried about coma as well as barrel distortion that comes with the ultra wide angle, but don't have any real experience with the ultra wide angle.
I recently bought the Rokinon 14. Mustache distortion is pretty severe BUT 1) the profile for it in LightRoom corrects for it very well and 2) Even uncorrected, it’s not at all evident in night sky photography. If you search my posts you’ll see one from late last year where I took pictures of a brick wall with that lens and my Nikon 16 to 35mm F4 zoom specifically to test for distortion. Not surprisingly the Nikon is better in every way. But the 14mm is less than $300 and you’re not going to be using it in situations where the distortion is going to be obvious.
The Rokinon lens works very well.
To focus on infinity this is the easiest lens to use. Turn the focus ring to the stop and your done. Most other lenses you cannot do that, you have to fiddle with the focus ring to get the stars sharp then use tape to make sure it stays there. Even with the canon 7D crop sensor camera I have, the rokinon 14mm works fine for most astrophotography and is a very affordable lens to buy.
