I am going on a photo workshop to Death Valley next year. The instructor recommended that you bring a fast, wide angle lens like a 16-35L 2.8 to use for celestial photography.
I am using a 5D2 (lenses listed below...).
Can I get away with using my 24-105 for wide angle? I know it isn't "fast" at 4.0 but I don't want to go drop a ton of money on a lens that I feel like I won't ever use outside of this workshop. I know renting is another option but if what I have will work I would rather just go with that. I have done some landscape work and have never really felt like 24mm wasn't wide enough (was shooting 15mm on a crop body actually but they equate to be about the same).
Also off topic from celestial - he also recommended you bring a fast telephoto... once again I only have the standard 70-300 IS USM.
Thanks in advance
