It was an excellent idea when you told me about it and I still think it is.
Direct reply: Because I somehow have to convince a bank to loan me like $12+K to have one each (atleast) of the expensive lenses, and 2-3 ec. of bodies, flashes etc.
I currently only have enough to loan out one "kit" 6mp body, flash and assortment of lenses from 19-400mm. They are not all the best lenses, but they get the job done. They are a combo of my "back-up" equipment and "travel" gear" as well as my older stuff that I have since "replaced" with genuine Pentax glass. the rest of my stuff I can sometimes let really good friends use for 24hr or less, but I am usually shooting enough during the week that it makes it really hard to sinc up to loan out my "good" gear.
(This is not an ad or invite, so don't start PM'ing me etc. w/ hey... whats your fee/availability etc.)
Extended reply:
And to all others wondering. Currently I have thought about this and talked with a few people. If your interested in this prospect please post it here. I do not have enough gear as of yet, but do have a fair amount that I do already loan out to some local MD'ers when needed. (Sorry no the 300mm F2.8 is not one that I can... its complicated) I also am in good with a Pentax Rep so I will foward this information over to Pentax USA via him as an idea for future programs, so post what you would like to see available to rent. (Besides, of course, the long-glass, but it will be interesting to see how many would be willing to pay the common prices to rent long glass, about $100+/day)
