Diving in a vault …

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.

VA-1 adapter for the OM-D E-M5 II available!

The VA-1 angle finder mounted on the OM-D E-M5 II

I got the first production grade adapter to mount teh VA-1 angle finder on the OM-D E-M5 II. It fits well and the visibility of the view finder is good. I have no experience yet, how the material will stand over time and usage. I used (first time) selective laser sintering (SLS) as production method for this kind of adapter.

With this adapter, the VA-1 may be mounted to yet another type of camera body.

You may order the adapter directly through my Shapeways web shop.

m.ZUIKO 7–14mm with polarizing filter

m.ZUIKO 7-14mm f2.8 with polarization filter

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.

Testing Dive-Computers

Testing equipment in mountain lakes.

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!

Threaded filter holder for the Zuiko 7–14mm f2.0 lens

Who says, that you can’t mount a threaded filter on top of the Zuiko 7–14 mm f2.0 lens? With a filter diameter of 105 mm it is possible. I tested with the bare holder for vignetting. Up to now, the results are promising.

Threaded filter holder for the Zuiko 7-14mm f2,8 lens

I designed and built a prototype on request. I couldn’t test the holder yet. None of the dealers in my vicinity stocks filters of that diameter. Since I wasn’t willing to spend more than 200 € for a quick test, I have to be patient. My customer will test the holder and I will report the results.

Polarizers are expected to produce strange effects when pointed at the sky. Nevertheless, they should remove reflections quite good across the whole image.

New Heavy-duty Buzzer

I built a new buzzer for photo booths. The new case is even more stable than its predecessor. As a bonus, it allows charging two AA cells independently without opening the case. The receiver is implemented using a Yongnuo RF-603. It may be expanded with a USB-dongle that emulates a left mouse click or hitting a key on a keyboard.
