You need a tripod and a non-moving subject to avoid blur, so I'll go out on a limb here and say "no".
Is this feature important and/or useable for the underwater photographer?

Will any of the mini domes designed for the 8mm panasonic fit the pt ep13 housing without changing the front control dial on the housing?We believe the Zen 9-18 semi-dome port should fit the new PT-013 housing _without_ any adapter as Olympus has gone back to the standard flat port that they have used on the PEN series of housings. The PT-013 doesn't have the larger bayonet locking ring, etc like the other OMD housings.
The PT-013 is only available with the flat port. and it should work great with the 60mm macro lens.
Right now if you buy any Oly OMD camera, PEN E-PL7, etc you can buy lenses and good discounts; ie the 9-18 at $200 off and the 60 macro for $100 off.
The YS-03 will work fine, but you may need to consider a better arm and tray, as the ones that come with it are going to be too small really.
I agree with Scott - the Oly EM-5 Bundle is a better buy overall and then put the money into lenses and a better strobe. You'll have a better investment long term. You're going to get 90% of what the new camera has to offer at least for stills. The lens discounts apply to it as well, making it an even better buy for those on a budget.
