I therefore uploaded the printing data to my Shapeways Shop. You may order a filter holder as 3D Selective Laser Sintered model directly from the shop. The filter holder isn’t as sturdy and doesn’t look that smug but it’s much cheaper.
Finally, the lid for the battery compartment is available for the Olympus OM-D E-M1 II. You may order it as spare part at via davinci, item number VP924500. Currently, delivery time is said to be 4 to 6 weeks.
With this part, if properly modified, you may use the BLH-1 battery adapter with the battery compartment closed. I ordered one and will write a modification guideline.
Sometimes you have to go deep for a shallow dive. I was shooting pictures with Harald Hois in a medieval vault. The vault is partly flooded, but lat weekend, the water level was far below usual. It was therefore difficult to move without stirring up the sensitive silt layer at the bottom. Nevertheless we were able to take a few nice shots.
Oh, yes. It can be done. I mounted a haida PRO II NC slim polarizer on my Olympus m.ZUIKO 7–14mm f2.8 lens. The filter has a diameter of 105 mm. Slight vignetting is still visible. The effect ist a bit strange when taking pictures of teh blue sky. It is quite promising when aiming at reflections. More tests will follow.
I designed an adapter to mount the VA-1 angle finder on the E-M5ii. During the next few days I will perform tests with the prototype. In case of successful tests I will produce a small batch of adapters.
I got a brand new dive computer a couple of days ago. It needs a certain number of operating hours in order to get the approval for public usage. I am therefore out and diving a lot. This may cause delays in answering requests. Please be patient.
The picture shows computers I got for testing a while ago. The current test devices are still top secret!
