That's a pretty severe mistake on their side.
Can you tell me, did the housing for the G9 have threads on both ports?
Only seen this housing for a brief moment and paid more attention to the craftmanship in general rather than important detail. Go figure.
What's your opinion on my theory of beeing able to do decent macro with the short port on?
Atleast on land I would say the G10 has a very good macrofunction even at the widest.
I own and regularly shoot the Patima G9 housing, w/ Dual Optically Connected Inon Z-240's and the Inon UWL-100 lens W/ Semi-Fisheye Dome.
The Patima G9 did come with 67mm threads on both the short and long ports. However, because the Patima G9's long port is not tapered out, you need to zoom in significantly to get past the vignetting, which is apparently why they changed the design on the G10. I use the long port with either single or dual Inon close-up lenses, and even though I need to zoom in to eliminate the vignetting, when I added a close-up lens, I have gotten some respetable results. Here's a couple of examples:
With the Patima G10's long port, you should be able to shoot some decent macro, but you will probably not be able to bring the camera in as close to the subject as you would like for underwater use. However, if you can add close-up lenses, which it sounds like you can with the adapter, then shortening the distance should not be a problem.
As far as the construction of the Patima G9, which appears to be similar to the G10, the housing itself is rock solid and is built like a tank. The housing is ergonomically well designed and controls all the buttons. Most of the buttons can be reached with your right hand and the window for the monitor is large. I am very happy with my Patima housing!
If I had to point out the negatives of the housing, I'd say:
1 - It's very heavy, so make sure that you combine it with floatation aids to assist with the weight underwater.
2 - The connection for optical cables only holds one cable, so you will most likely need to fun your first strobe as a slave to your second strobe, but that should not affect performance of the strobes at all.
Hope that helps!
