Zoom and focus mec hanisms The job of varying f ocal length in a zoom lens r equires a fairly comple x mechanism that tr anslates zoom ring r otation int o precise gr oup mov ement along the optical axis of the lens.
Aperture and e xposure The aperture in a lens—also kno wn as the “diaphr agm” or “iris”—is an ingenious piece of mechanical engineering that pr ovides a variable-size opening in the optical path oft en used to contr ol the amount of light that passes thr ough the lens.
Other macro lens c haract eristics you should know about Macr o lenses are specif ically designed to deliver optim um optical performance at very short focusing distances , and will usually be sharpest at close range , but that doesn’ t mean that you can only use them for macr o photogr aphy .
Use your lens hood! The lens hoods pr ovided with most int erchangeable-lenses ar e not just accessories to be used occasionally . They ar e an impor tant part of the lens’ s optical system and should alw ays be used in order t o ensure optim um performance.
Snapshots The t erm “snapshot” ref ers to any phot o opportunity that arises spont aneously . Y ou’ re shooting snapshots when you tak e your camer a for a w alk in the park, or on vacation, or ev en when you’ re in “serious” str eet-shooting mode.
Internal f ocusing mechanism In this type of lens, focusing is achiev ed by moving only the int ernal elements. The ov erall length of the lens r emains constant, and the filt er mounting thr ead at the front of the lens r emains stationary during focusing.
