Voking macro prstenovi Auto fokus komplet za Canon DSLR 13mm, 21mm, 31mm (VKET3-C)

ZNAČAJKE:

The autofocus will work in principle, but is often no longer able to work for longer intermediate rings or when using Multiple. The reason is: the brightness and contrast of the viewfinder image decrease the sharpness and is found only in a very small depth. It should then be focused manually.

Because of the extremely small depth of field and the extremely short distance to the subject is strongly recommended the use of a tripod. From the hand often threatens shake.

The appropriate inter-ring length is dependent on the focal length of the lens. For lenses with short focal length usually requires only a single intermediate ring to achieve a far greater magnification. If one or more rings may be between mounted, depending on the lens used, the point of focus but also migrate into the lens. Therefore, lenses with relatively short construction and longer focal lengths, from Standard and older, more appropriate than short focal lengths or wide-angle zoom lenses.
