I was sent a LensRack Single Rail Kit and LensPacks from LensRacks.com for review purposes.
I've gotta say, I really like this setup. It's really useful for my OCD issues and as far as storage purposes go, I'm totally happy simplifying my lenses.
The only changes I would make is an easier way mount the rail onto a bookcase for example. I'm slightly concerned I'll accidentally bump one of the taller lenses and knock the whole thing off of my desk. I'll have to look into securing the rail down somehow in the future.
The LensPacks are what I really liked. I hate having to spend time taking the caps off and putting them back on. Granted, this leaves a little room for debris getting caught in between the lenses and the LensPack but, so long as I keep an eye on what I'm doing, I think I'll be fine.
All in all, I really like the LensRack and the LensPacks. I'd recommend them to a photographer looking to save a serious amount of time.
