Thanks for the input! I'm aware that there might be more lucrative businesses out there than lens rentals, but I do have to invest a certain money into film gear and believe that in that case, lenses are the best. I should have added that I'm planning on consigning them with a local (LA) rental house, which is why I'm trying to gather more information on what they rent out a lot.
I've talked to quite a few people but was just looking for even more personal opinions. Generally I'd like to invest a bigger chunk of money into one good kit, rather than getting several (again, I'm not a DP so it's like I will be using them myself constantly). Thanks for the feedback!
