A standard through-the-lens focusing system does the fine tuning after that.
At its most basic, a macro lens has an unusual focusing system that allows the lens to extend further and thus focus more closely.
In addition to its superior stabilizer and focusing system, it does better in low light, with fewer of the dancing, grainy pixels that mar the HC3's dim-setting work.
Because you know a major difference between these micro-S.L.R. cameras and real ones: micro-S.L.R.'s use the same slow focusing system as pocket cameras (the ones that miss so many split-second opportunities).
Unlike a single-lens reflex camera, where the photographer looks through the lens while composing and focusing, a rangefinder camera uses a separate viewfinder with a "split-image" focusing system.
It protects the pupil, the iris, and the inside of the eye from penetration by foreign bodies and is the first and most powerful element in the eye's focusing system.
Extracted by a 7-cm Immobiline DryStrip, pH 3 to 10, Ettan IPGphor isoelectric focusing system.
Next, we apply Theorem 2.1 to Brillouin electron beam focusing system (1.1).
A dynamic focusing system is designed, intended primarily for broad flat field galvanometric laser scanning applications.
In this paper, we concentrate the attention on focusing system made by nested mirrors.
A novel structured light-field focusing system is developed for flowfield measurements and visualization.
