Question Looking for help with a 12-45 zoom gear

[Zachb13]

Hello, I am currently using the Olympus EM5 Mark II in the EP PT13 Olympus housing. While the camera does great for what it is, I am looking to upgrade my mid-range lens. I am really looking into getting the Olympus 12-45mm Pro lens to replace the 14-42 kit lens. The only problem I have is I cannot find a zoom ring that is said to be compatible with my housing. Has anyone else had this issue and found one that worked? Can anyone on here 3d print one? Thanks!

Are you sure there is a port available for that lens?

I am using that lens with the AOI DLP-04P 4" semi dome port on an AOI housing. I _think_ it would fit on the pt-ep13 using that port. It won't zoom all the way to 45mm in the PT-EP13 port (iirc, something like 37mm it taps the inside of the port).

Unfortunately I don't have an EM5-II anymore, so I can't check if the AOI LG-OM-1 zoom ring for the 12-45pro would work, but it might. The main difference is that AOIs gears are thinner than the ones Olympus used to sell. It might be a bit tricky to line up.

For what it's worth, the AOI zoom gear meshes nicely with an Olympus gear intended for their housings; my guess is that it would work but like d^ says above, placement on the lens will be tricky. You may need to hold it in place (fore and aft) with rubber bands. Also, make sure you get the AOI gear intended for PEN housings and not OMD housings.
