subject: Canon Lenses Produce The Highest Quality Pictures [print this page] canon lenses are the ef lenses, which stands for "electro-focus".They were introduced in 1987 on canon film lenses. Ef lenses have a motor in the lens body to help assist with focusing. They are compatible with all of the current generation of canon digital slrs. Most canon lenses have similar controls. They have a focus ring to help the photographer focus the lens manually,a switch to choose autofocus or manual focus, for the focus mode Image-stabilized lenses allow the photographer to turn the stabilizer on or off as well as select different modes of stabilization for different modes of, one for normal use and one for panning. Zoom lenses have a zoom ring to choose the zoom range. The lenses also have a focus distance switch for the focal distance, which can help reduce autofocus time.Canon lenses are well-corrected for distortion, and have excellent color fidelity and contrast. In addition, they are characterized by superior lens construction. Canon lenses are adjusted through the camera body with no on-lens control. All modern canon lenses focus with a motor in the lens. If you are near-sighted, this is an especially nice feature since it is difficult to focus manually if you wear glasses.
Canon lenses are certainly a good investment, they will last you for years and will most likely be compatible with all new canon dslrs.Canon lenses are designed and manufactured to produce the highest quality images, constrains of technology, manufacturing and cost mean that some minimal aberrations still exist in the lenses. This new addition to dpp aims to correct these minor aberrations and produce even higher quality images. The adjustments available correct four factors in the images. Otherwise known as corner-shading or vignetting. Digital cameras are very susceptible to light not striking the sensor at the correct angle, and with some lenses it is possible to see a slight fall-off in the corners of the image where it looks darker than the rest of the frame. This adjustment aims to even out the lighting across the frame. With wide-angle lenses, it is possible to see distortion around the edge of the lens - straight lines become curved, and subjects at the edge of the frame are distorted. This adjustment ensures straight lines are straight.Canon lenses are the choice of many imaging professionals the world over.
