Frage von hd2006:
Hi, I bought a used Redrock DOF adapter. Now I once made quite a few test shots. On the whole, and quite a beautiful thing. In a test setting I have filmed against the sun. Here you can see the sun as a "wobbly" wheel. This is so I think the rotation of the focusing screen in the DOF adapter. With all other test images are very good actually, I'm not sure now is whether the normal, a setting error or if maybe the ground glass is broken, since I have bought the part needed. At normal settings without lens can be seen in footage from nothing but just direct sunlight. Maybe someone can give a tip.
Thanks
Antwort von Axel:
If it is very light, for example, if one is filming in the sun directly, the automatic exposure tends not only of most, but really
all camcorder to minimum aperture, the exposure time to radically shorten the next. Very short shutter times but effectively stop the motion blur, and the grain size of ground glass in the adapter is as streaky, hazy layer visible. Remedy lean gives a strong ND filter and manual handling for - depending on the camcorder's frame rate and chip-readout (CCD or CMOS) - 1/25tel 1/50tel or shutter.
For faster shutter speeds you need a faster rotating drive. The focusing screen is synonymous with old batteries will not quite fit into the corridors, which you could also check.
Otherwise: Backlight is your friend.
