Well, it was not especially easy but I finally got the Inon 165 AD FE lens onto the Ikelite 67MM port. Also made an extension arm for the Sekonic, tray knobs instead of the Ike supplied carriage screws, custom strobe deflector with dual outlet Inon optical sync plug. It may vignette just a bit in the corners but it is still far, far, far wider than with the standard port and even a good 30% wider than with the Inon/Ikelite/Epoque 100 degree lenses.
Mine took a little getting used to as I started digital with a DiMage Z3, still find a Z6 to be the most intutive camera to use, really like the EVF. Been happy with image quality because I only shoot the lowest ISO and least compressed JPEG.
On the Canon I have trouble with the batterys making contact, once good it works fine till I open the door again to unload images, bout ready to use the USB transter instead.
I recommend getting the Duracell Precharged or the Sanyo Eneloops (same cell I think). I don't have any problems with contact on mine---hmmm. I don't press on the door but gently and then push it to the side. Make sure the contacts are clean, clean, clean on the batteries themselves. Don't use alkaline cells, they don't work in this camera.
I have heard that some people gently pry the tabs up ever so slightly and then stuff a tiny little piece of foam under the tabs. So far I have not needed any such thing. I only use my three 570IS for the underwater housings, I have other cameras for surface shooting. The Ikelite housing BTW presses up on the battery door just a bit which may help.
I am still fighting the lens issue but I am gaining on it. I really, really, want to remove the entire port and machine it shorter but do not know how it is installed into the housing. The port needs to be 3/16ths shorter.
Yes I do, bought new from best-try. I'm using various 2300mah+ NiMha batterys, alkalines are a waste of money, I think part of the proablem is at least once when I was ina big hurry I got the batterys in reversed. Even have thought about a external battery pak for C cells, 5000mah!
I'v used mine for farm records, plenty of winter shots the last two years, my folks 50th wedding anaversory, even made an adaptor to mount it into a 2 inch focuser on telescopes, that didn't work out as I didn't have enough infocus. I gave up carring it day to day when I pickup up a nice used Konica/Minolta X1.
Well, you may need to see if you can reset the contacts if you squished one of them
The Sanyo Eneloops and the Duracell Precharged are only 2000mah but they seem to work better than the standard 2300mah sorts, have a flatter voltage fall off.
I hate getting all set up with a flash and lenses etc and a housing and then squash the camera or loose it or drop it taking surface snaps. Nope, my underwater cameras are dedicated units. To much time and money invested to be sitting with a broken camera and a perfectly good housing for which I can no longer source a camera.
