For a larger magnification, for macro photography
The intermediate rings are combined as fiddleback between lens and camera and increase the distance between the lens and the sensor plane. It is equivalent to a much larger extension of the focusing mount. Effect: The magnification is increased, thereby also reduces the depth of field. A subject at close range is achieved from the background, isolated. These intermediate rings can be used with many, almost all, lenses. Most effective for close-ups are short focal lengths in the range of normal or short telephoto focal length.
Three Rings for more flexibility
The set consists of three intermediate rings in different sizes. These can be combined. This will give you with one and the same basic objective very different magnifications. Please note: To extend the path of light through the intermediate rings. The exposure time is e.g. the scale of 1: 1 four times longer. If necessary, at peaceful objectives, we recommend using a tripod.
Contacts for data transmission
To ensure a problem-free working and elegant as possible, all 3 intermediate rings are provided with gold plated contacts. So is the transfer of EXIF data as well as get the iris control. Also exposure in TV or AV mode is unrestricted. Finally, the autofocus works thanks to the contacts properly.
