NOTE - if you have flat port 72 for the NEX 18-55mm lens, you will need this flip diopter holder instead
Imagine diving in cold water with a group of new dive club divers who want their photos taken and then seeing a clear shot of a small hermit crab with its eye stalks waving about and then a nosy blue cod swims up for a photo right followed by spotting a blue eyed triplefin (tiny) sitting on a rock. If this involved finding my BCD pocket zip, removing attaching and then detaching and replacing a diopter in my pocket, while wearing thick dives gloves, I'm fairly sure I wouldn't bother. With this gadget you can flip the diopter up out of the way or back in position immediately and it's light, stable and easy to attach. Just remember to wind out your lens again if using a zoom - photos of nudis taken at 14mm with the diopter on just look weird.
