LYTECUP exposure control device

Canon HV20/HV30 users also have no manual control over gain, arperture and shutter speed. The LYTECUPTM looks like a useful device. It seems to have a dimmable and diffused LED light source inside and allows to set arpertures and shutter speeds while keeping gain at zero.

I have no experience with this device but I think it would work just the same on the HF100. Maybe some adaption to the smaller lens diameter of the HF100 would be all that is needed. For someone experienced in electronics this could be an interesting DIY project using a LED, a diffuser, a battery, potentiometer, some capacitors, resistors and a NE555 integrated circuit to produce the pulse width modulation (PWM) for dimming the LED but its probably not worth the time if you can buy it readymade for a fair price.

You could use a light meter (expensive) or your point and shoot pocket camera to determine the correct exposure of a scene at a low ISO and 1/50 shutter speed. After this set the HF100 to Tv50 then set the correct arperture using the LYTECUP device. Some experiementing will be required though to find the corresponding ISO value of the "zero gain" HF100 setting.
