Testimony from Mike Sleeper: I am having a great time with the IMVIO case and lenses. I'm a former commercial photographer and solely shoot landscapes these days using a big medium format film camera (my site is www.sleeperfineart.com). I have been using an iPhone constantly for years and the new IMVIO lenses have provided me with an immense new range flexibility. I'm taking shots I would have previously passed up. A large portion of the images of Paris on my facebook page are shot with IMVIO lenses.
