Hi, I'm looking to rent a lens for an upcoming airshow but I'm not really sure which one. I don't want to spend a TON of money, i'd like to keep it around $40-50 maybe, but if there is a lens that's really worth the extra money I might be willing to pay more. Basically what it comes down to though is the Canon 70-200 4.0L or the Canon 70-300 IS. I'd really like to get an L lens but is 200mm enough to get up close to the airplanes? Is the L lens a lot better than the non L? Here is the link to the lens I can rent, take a look if you think you can help me. Canon Telephoto Lens Rentals Any help is appreciated, thank you!
