Roger Cicala was originally a physician who photographed as a hobby. He founded Lensrentals.com in 2006 as a way to justify buying more equipment to use.
Much to his surprise it grew rapidly and he left his medical practice to run Lensrentals full-time in 2010. Lensrentals is now the largest imagine equipment rental firm in the U. S., employing nearly 200 people. Roger is no longer the CEO of Lensrentals, but does still run the QA, testing, and repair departments.
As a side effect of running an equipment rental house he became interested in optical testing and manufacture and started Olaf Optical Testing in 2011 and C-4 Optical Design in 2014.
C-4 Optical Design prototypes weird lenses, such as the 4.9mm f3.5 Hyperfisheye lens. Olaf Optical Testing is now considered one of the premier optical testing facilities in the U. S. and does optical testing and consultant work for NASA, Jet Propulsion Labs, Sony, Leica, and Sigma among others.
