The total magnification results from multiplying the lens magnification with that of the pocket telescope. The modern lenses the mounts of which offer the comforts of the pre-set diaphragm and the automatic diaphragm presetting device and additionally operate as a natural light trap, too, have, however, when used as a magnifier, a distance somewhat too large between front lens...  1, record 1, English, - automatic%20diaphragm%20presetting%20device

MARKHURD's aerial photo capability is second to none. We currently have ten(10) aircraft, all with airborne GPS [Global Positioning System] equipment and several with dual camera mounts, that have photographed well over 1, 000, 000 line miles of imagery in 35 countries.... Twelve(12) recently calibrated precision mapping cameras with 3-1/2", 6", 8-1/4" and 12" lens facilitate timely project completion. Five(5) complete aerial photography reproduction laboratories greatly enhance our ability to complete this important task in a timely manner.  1, record 2, English, - aerial%20photography%20reproduction%20laboratory

Fortunately, you can still meter using the stopped-down metering approach on most cameras. By pressing a depth-of-field button, the camera is placed into stopped-down metering mode too. The lens is stopped down to the taking aperture automatically on some adapters. On T-mount and other purely mechanical mounts, you may have to turn the aperture ring to the desired taking aperture. In either case, the camera is now metering at the actual stopped down aperture. You can set the shutter speed and aperture as desired, based on your meter reading.  2, record 3, English, - stopped%20down%20metering
