Large aperture lets in more light....meaning all being equal...can use a much faster shutter speed (to 'freeze' fast action or to minimize blurriness due to shaky hands) to get the correct amount of exposure.Originally posted by lufu
so a large aperture, smaller f value.
what is the purpose of such large aperture and small aperture, what kind of effect would be achieve
I think it's difficult to design a long-zoom lens (like urs, 7x) that's very fast.....so gotta have some compromise.Originally posted by Flare

what is meant by Fast (f/1.8-f/2.6) ,aspheric lens design, with 10 elements in seven groups as compared to
f/ 3.0 - f/ 3.6, 11 elements in 9 groups
should higher f be better or lower? what is elements and groups?
