67mm filter thread on that port?

I just started using the SubSea +5 on my Leica 45mm macro on the OMD. Works beautifully! I normally wouldn't consider using wet diopters, but the optics on the SubSea seem really very good.

Thanks Hermit Crab. I have been shooting with RC Mode Off. The TTL delay is there and relates to the pre flash. Like I said, it's not that bad and the perfect flash exposures every time more than makes up for it. Those who have been shooting with compact cameras will probably not notice it at all. Those who are used to their 5D MKIII with YS-250's will definitely notice.

There is no way to eliminate the TTL delay except by going completely manual. The other issue that slows you down in rapid fire shooting is the recycle time of the camera's on-board flash. And you can minimize that by setting manual strobe power to 1/64.

You will wan to use manual focus with video. Continuous auto focus will hunt continuously, just like almost any other camera. If you are using the 8mm fisheye, just set it at around f8, prefocus on say, your fin, and the depth of field is so huge that you're good to go for most subjects.

Thanx heaps - I don't see the ttl lag as being a major issue as most of my subjects are fairly stationary - was just looking for confirmation on how to deal with this. Any ideas on how the E-M5 handles video under water with focusing?

Yes, there is a little lag when using the OMD with TTL optical with the YS-D1s. I'd rather not have any shutter lag, but in most cases, it's not so much as to be a problem and the perfect flash exposures every time more than make up for it. When I really can't afford the shutter lag or wait for the internal strobe to recycle, I use the 1/64th power setting on the OMD's internal strobe, and go completely manual. In this case, there is no shutter delay.
