As the camera works with the lens extension (called optical prism) to give them the same level of optical zoom, such as the expansion of?
If this were not the zoom of the camera hobby out of fashion?
Couldnt find any information on the Internet about it.

ReplyDeleteI has no idea what that means, but how it works .... lol
Abstract
The inner focusing zoom group has the primary goal of the refractive power of a positive lens group, the second negative refractive power, a third lens group of positive refractive power and a lens group, with the fourth power of positive refraction, in order from the side of the object in which at least the first target, the third and fourth lens groups shift lens group in an object named along the optical axis with a wide angle to telephoto zoom lens as an increase in the airspace between the first lens group and the second lens group, a small gap between the dryreduced second lens group and third lens group and an air space between the lens and the third group lens group meetings, which moves the second lens group to the object along the optical axis during the approach and meet several conditions.
