I don't know what my problem is sometimes, I am just not all that swift. I made 12 dives in four days and shot well over 1,000 pics, closer to 1,500. Among other misadventures I shoot through much of the first day before noticing a dirty film over my port lens. Arrrggggh. Yeah, it shows on the pics. I dunno, I guess it was in part the port was never cleaned since new and something must have then created a film when exposed to the seawater. It cleaned off with a gentle wipe, clean water and a soft microfiber towel and never returned.
