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. Zoom mechanisms must be pr ecisely manuf actured to e xacting toler ances so that all elements and gr oups stay in perf ect alignment[...]

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. Aper ture and sh utter speed ar e the two primary means of contr oll[...]

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 . Many macr o lenses ar e also capable of excellent per[...]

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. There ar e exceptions, such as when an on-camera f lash is used and the lens hood casts a[...]

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. The k ey is to captur e the moment, and that requir es mobility and speed. Some photogr a[...]

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. The latter char acteristic is an advant age when using a polarizing filt er . Other advantag[...]

Fixed focal length lenses, commonly known as "prime lens" or simply as "primes," can complement your photographic vision in a number of ways.
