Some EP-L1 underwater picture + 9-18mm
I went to Cabo, Mexico for a long weekend, and had a chance to do some underwater photography.
I am very much a novice when it comes to the underwater photography. Though I have done it for several years, I do it only 3-4 times a year.
To preempt possible questions - corner sharpness (or lack their off) is not the property of 9-18mm lens, but artifact of using Olympus housing with a flat lens port as opposed to more expensive housings with dome lens ports.
