Owning a fisheye lens is almost comparable to purchasing a fully pimped out Mac computer in that you’re paying a pretty penny for the frill of having it but if the type of work you do doesn’t coincide with what you can get from it, is it really worth spending all that money? If all you do is write emails, listen to music and surf the web, perhaps a $2,000 laptop is not warranted. Whether I’m traveling or not, the majority of my photographs are comprised of street work involving either people or locations and for content like that, having a lens like a fisheye that potentially limits you to just one of the two is not helpful.
I had rented the Nikkor 10.5mm f/2.8 fisheye lens from Borrowlenses.com for a vacation a couple years ago and throughout the trip, my wife was very perceptive in noticing how fascinated I had been with photographing with it. To a point where she had offered to purchase the lens for me as a holiday gift and as much as I appreciated her supporting my lust for anything photography, I was unwilling to have her spend $800 on a lens I might use as oppose to one that I would use all the time. From a creative perspective, it’s fun to shoot with the fisheye but to avoid being consumed with the feeling that you need every lens out there, you always have ask yourself “how often will I really use this?” In my case, not very often but if I ever crave for it again, I’m more than willing to pay to rent it rather than pay full price for it.
