A discussion during an oly-e.de user meeting lead to a series of camera grips. The latest prototype is designed to simplify the handling of long telephoto lenses.
It is called LoopPod. I'm trying to build a small batch for reasonable money.
The design allows to carry heavy lenses easily by the loop handle. It also allows to hold the lens in a more stable fashion.
With an angle of 114° the Zuiko 7-14mm approaches the limits of wide angle optics. The highly convex front lens is one of the constraints building such a lens.
It also features a built-in lens hood that doesn't allow screw-in type filters.
I took some measurements and found out, that a filter size of 100 ×75mm (4 ×3") may be used under certain circumstances without vignetting.
I therefore designed a filter holder that accepts Cokin X-PRO filters or similar sized filters.
My prototype is built from black plastic using SLS technology. Two o-rings provide enough friction along the thin edge of the filter to keep it in place.
There are quite a lot of cameras on the market that can't be controlled by software through a PC. CamControl closes the gap. It consists of a USB dongle and a piece of software. The dongle contains all the circuitry neede to interface to the USB port of a PC or Mac. It also contains a 3.5mm stereo jack to connect to a camera remote control connector through an adaptor cable.
You may "press" the relese button half-way and full under software control. You may do this even with a radio transmitter between the dongle and the camera.
The dongle acts as a HID device (like a mouse or keyboard) and doesn't need any additional drivers for Windows. The software interface is open source and well documented so it's up to you to add further functionality.
