The batteries also powered the ME F's exposure control system.
2.
The exposure control system used vertically arranged + / o / light emitting diodes ( LEDs ) on the right side of the viewfinder to indicate the readings of the meter versus actual camera settings.
3.
The " Magic ", although intended for amateur photographers, was relatively expensive at 435 DM . It featured an automatic exposure control system driven by a coupled Bulb ( for long-exposure night photography ).
4.
The exposure control system consisted of a needle pointing along a vertical f-stop scale on the right side of the viewfinder to indicate the readings of the built-in light meter ( center-weighted with a silicon photocell ).
5.
It is operable without batteries and only needs the two S76 or A76 batteries, or one 1 / 3N battery to power the light meter, which consisted of an internal 60 / 40 percent centerweighted system linked to a center-the-LED exposure control system.
6.
The DP-3 introduced three innovations : a silicon photodiode light meter ( a first for Nikon SLRs ) for faster and more accurate light readings, a five-stage center-the-LED exposure control system using + / o / " LEDs, and an eyepiece blind.
7.
The major improvements in the FM3A compared to the FM2N are the hybrid electro-mechanically controlled aluminium-bladed focal plane shutter, the aperture priority auto-exposure mode, the match-needle exposure control system and provision for through-the-lens ( TTL ) off-the-film ( OTF ) electronic flash automation.
8.
The camera enters the market with its own tier entry into the range, boasting features such as a 24.3fps, stereo audio recording capabilities and like others in the Sony Alpha range it has high sensitivity with ISO 100 to 16000, several noise reduction features, 8 white balance presets including custom balance and exposure control systems.
9.
This consists of a centre-the-needle exposure control system using a galvanometer needle pointer moving between vertically arranged + / over / underexposure markers at the right side of the viewfinder to indicate the readings of the built-in full-scene averaging, cadmium sulfide ( CdS ) battery light meter versus the actual camera settings.
10.
The FT's exposure control system was a " center-the-needle " system using a galvanometer needle pointer moving vertically at the lower right side of the viewfinder to indicate the readings of the built-in, open aperture, TTL, full-scene averaging, cadmium sulfide ( CdS ) light meter versus the actual camera settings.
