PT-EP10 compared to PT-EP05L / 06L

Preliminary short for background: I am among other things still the owner of the E-1 and the PM MATCHING case PT-EP06L, so I'm also on a comparison of the two systems. First of themselves owners of E-PM1 or the EPL3 must have to ask (rightly) whether an "upgrade" high and of course even more so from the price to be called forth also worthwhile. This question must be answered for himself but everyone. For me, ultimately the consistently good reviews of the E-PL5, which have repeatedly described a significant leap in quality compared with its predecessor and especially the greater flexibility with regard to the possibility of using different lenses were decisive.
The delivery is next to the housing the same as usual contain: Diffuser, silica gel, O-ring grease, etc. but again no Zoomgear which must be purchased separately.
First, about the differences to the PT-EP06 (5) L: The two largest anomalies are that the target Lights and the 67mm connector on the port have disappeared. The target-lights I did not care that I have never used anyway, but the absence of 67mm connection made me ponder briefly. The solution, however, is simple: there is a simple click-on adapter of Olympus 67mm for the housing. Although costs again extra, but works well. However, I have found another solution for me, namely a specially made for the housing 67mm flip adapter. He was a little more expensive, but of convenience can not be beat, as it is not always the UW lenses must were plunged / unscrew, but only up and down keys, a big advantage when you're in a little bit faster.
The second major advantage is the large port: One can in the housing, the 14-42, 12-50 and the use the 60mm macro, so I'm depending on gesuchtem motif very flexible (even more flexible with the relevant articles).
Caution: for the 12-50 there as far as I know no official zoomgear of Olympus, so I have worried a foreign product, but that works just fine, as made especially for this case / lens. The 12-50 can also be used without zoomgear, however, very limited: Two settings: UW-Wide OR UW-Nah (if one chooses the appropriate mode in the camera automatically moves the lens in the E-Zoom mode in WW or Close ( but NOT macro!) mode.
Please note: Even with the zoomgear can switch during the dive NOT in the macro mode of 12-50mm! With zoomgear it is, either macro mode or zoom mode. (Since you specify the switch button can not operate).
I think Nauticam actually a port designed for this problem with Zoomgear, but was priced beyond my budget.
Otherwise, as you would expect, all camera functions can be operated and the housing is in handling very user-friendly and also "relatively" easy because usually manufactured of plastic, as in Olympus.
The case has, as usual, 2 optical ports flash and a hotshoe for flash, focus light, video light or whatever. I take him for a Sola on small flexible arm to secure it.
Practice: I had the set in August / September in Sulawesi in use since there is no real difference to the predecessor is determined, as you would expect and as it should. The only change was at 12-50, the difference between manual and e-zoom, is pure matter of habit. With the kit lens I have the set not used, so can not say anything.
Conclusion: camera housing hit currently with about 1,200 to beech (without accessories), who has the E-PL3 and E-PM1 is already at home, must decide for themselves whether it is worth the upgrade that price. Ultimately for me was crucial that I can use multiple lenses, to the accessories, such as macro (wet) lenses and the Inon WW with dome port (external) can continue to use. And with the E-PM1 with housing I have a high-quality backup system, which also loosely fits into the trunk.
