Many camera models measure the light that reflects off of the film plane, which controls the flash duration of the electronic flash. This is denoted TTL flash metering. Some electronic flash units can send out several short bursts of light to aid the autofocus system or for wireless communication with off-camera flash units.
Cameras for the micro four-thirds system are designed with the option of a replaceable lens, and lenses that conform to this proprietary specification are accepted. Cameras for this system have the same sensor size as the Four-Thirds System but do not have the mirror and pentaprism to reduce the distance between the lens and sensor.
Due to the use of thermal imaging, the AN/PAS-13B does not require low levels of light to operate, and it will not shut off like most night vision if hit directly by light. The thermal imaging sensor within the sight requires a low temperature to operate, so a cool-down time of less than 2 minutes is required at startup. The AN/PAS-13B comes in ...
The assist light (also known as AF illuminator) "activates" passive autofocus systems in low-light and low-contrast situations in some cameras. The lamp projects visible or IR light onto the subject, which the camera's autofocus system uses to achieve focus. Many cameras and nearly all camera phones [a] lack a dedicated autofocus assist lamp ...
The 35 mm/2.8 Minotar/Minoxar lens was very sharp, with low distortion, while the camera's metering-system's capability to produce excellent results especially under low-light conditions was outstanding – using exposure times of up to two minutes. Some models have a 2x backlit exposure switch and a 10 sec timer switch.
The line comprises two camera body models, the ST (Studio) and LT (Lite). The Arricam ST is intended as a full-capability camera, including two camera magazine mounting configurations, whereas the Arricam LT is optimized for smaller, lightweight usage in handheld and Steadicam application, with only the option to mount the magazine in the rear ...
The IR light emitted from the enemy's active device would be clearly observable to a anyone employing an AN/PVS-4, making the enemies position easily known. Reticle burn-in was also addressed. One issue that persists even in production models is the tendency for the projected reticle pattern to become washed out in bright light.
The Olympus PEN E-PL5, announced on September 17, 2012 [1] is Olympus Corporation's tenth camera that adheres to the Micro Four Thirds (MFT) system design standard. The E-PL5 succeeds the Olympus PEN E-PL3, and was announced in concert with one other model, the Olympus PEN E-PM2 (a simpler version of the PEN E-PL5 and the successor to the E-PM1).
