I've rented from https://www.lensprotogo.com/ before (in that case it was usage of a $9,000 Canon EF 500 f/4L IS lens for a special trip to Yellowstone where the expense was worth it). Great service from them. If you live in any major metro area, check to see if there is a local camera store that has rentals. Perhaps the cheapest way is just know what the values are worth on ebay, buy one on ebay, use it for 2 months for storm season (for example) and you should be able to sell pretty much at the same price on ebay less commission (Canon L lenses for example don't lose value unless a new model comes out or you damage the lens).Does anyone have experience with renting lenses? I really want to try out a wide angle lens, but I won't have the funds to outright buy one this year so I'm thinking about renting one. If anyone has a company that they recommend or any tips I would appreciate it.
