However, maintaining an identical field size at varying camera-subject distances and focal lengths must be handled with caution as it applies different amounts of perspective distortion to the image: Wide-angle lenses expand a perspective, while long focus lenses compress a perspective ( the famous dolly zoom, taken with a variable focal length lens, is a vivid, intuitive demonstration of this effect ).

However, some flashes have the capability to " zoom with the camera " and concentrate their light into a narrow beam for use with a telephoto lens.

However it was criticised for slow focussing and excessive shutter " lag ", and for a lack of image stabilisation which often made the long end of the zoom impracticable.

However, square or rectangular lens hoods should not be used with zoom lenses whose front elements rotate as the focal length is changed, as the hood will rotate as well, blocking the angle of view.

However in most cases the inclusion of an inexpensive zoom lens is to maintain a low entry price and maximize usability for the beginner photographer.

However, phthalocyanine is more sensitive than cyanine to writing laser power calibration, meaning that the power level used by the writing laser has to be more accurately adjusted for the disc in order to get a good recording ; this may erode the benefits of dye stability, as marginally written discs ( with higher correctable error rates ) will lose data ( i. e. have uncorrectable errors ) after less dye degradation than well written discs ( with lower correctable error rates ).

) However, pipelining at that level was already used in some high performance CISC " supercomputers " in order to reduce the instruction cycle time ( despite the complications of implementing within the limited component count and wiring complexity feasible at the time ).
