a portion of the rectangle within the image circle, resulting in a magnifying effect or lesser angle or view. Some photographers love the angle of view magnifier because it allows lower focal length lenses to masquerade as higher powered telephoto lenses. But...

Fans of telephoto lenses will be delighted, because their lenses will let them "see even further." A 300 mm becomes, as if by magic, a 480 mm! On the other hand, those who stick mainly to wide-angle lenses will be disappointed that the images are skewed. If...

in a magnifying effect. Some photographers love the magnification factor because it allows lower focal length lenses to masquerade as higher powered telephoto lenses. But it is, after all, just a masquerade because the lens's focal length is still 50mm even...

for just the lens of equivalent quality if you were to use it for a DSLR. Quality extreme telephoto lenses are expensive. Unless you pay significantly more, even purchasing a DSLR plus a long telephoto lens, you would be unable to match VistaPix’s functionality....

for focal lengths from 50mm up to 490mm. You can't remove this lens and replace it with another one just yet, as compatible macro and telephoto lenses for this camera aren't available. Note that we can't recommend activation of the camera's digital zoom function....

so the focal distance is not the same (the angle relates to the diagonal of the lit surface). 35 mm in 24 x 36 can translate to 7 mm with, say, a 1/1.8" CCD sensor, and vice versa. To simplify and standardize the principles of wide-angle, telephoto lenses,...

for camera movement for any lens that will fit an SLR, at no extra charge. The second, built into the lenses that ship as options with the Canon EOS 450D and Nikon D60, is more effective. But lenses that include it cost more for the same level of quality. From...

second for up to 11 RAW images or 32 JPEG images. Just like other professional Canon cameras, it will accept more than 50 EF lenses for your wide-angle, macro and telephoto needs. An optional wireless transmitter will blast your photos into your network. Definitely...
