From what I know about Rajala the prices are usually rather high. Not sure if they rent out lenses.
Thanks for the links, Tmuussoni. I simply couldn't find any when I was searching. I'm using a Canon 5D. I don't know what I will do with a UWA lens as I doubt I will use it much after the trip. Also, the 5D doesn't really go above ISO1600, so shouldn't I be going for a faster lens to prevent long exposures?
I can speak only of my previous experience, but UWA is extremely useful when shoothing northern stars or astrophotography generally. I think you are going to find 14mm (UWA) more useful than you think. I had whole bunch of situations where 24mm or even 21mm were simply not wide enough.
So basicly a 4 day lens rent is going to cost you atleast 150€, possibly even more depending on which lens you will choose. Also the more expensive lens doesn't mean it's better when shooting at night. Shooting stars seems to bring out the worst on lenses. For example, the 1500€ Canon EF 24mm f/1.4L II would not be my first choise when shooting astrophotography as it has kinda terrible coma. By f/2.8 it's ok, though.
So that's why I suggest you the Samyang. You might as well buy the Samyang brand new for ~350€. If you don't end up using it after the trip you can always just sell it and get ~80 % what you paid for it. Still seems smarter investment than just renting a lens, just my 0.2 cents . On the downside, there are also owns tricks when using the Samyang, so you better practise using it before your trip (such as no hard stop at infinity, so you better know how to focus it properly as you don't have Live View on 5Dc).
And by the way, ISO 3200 is the max. ISO on 5Dc via expension. ISO 3200 is still very usable with 5D classic. Of course the files are not as clean as compared to 5DmII or 5DmIII, but ISO3200/1600, 14mm lens at f/2.8, and 20-30 sec exposure will go a loooong way when shoothing northern lights .
Good luck in your decision
