Name: DK-21M
Origin: Japan
The magnification is 1.17 times
DK-21M is mounted on the outside of the eyepiece, which can achieve a 1.17 times viewfinder magnification effect, which is suitable for macro and remake photography that requires focus and composition. At the same time, it prevents stray light from entering, facilitating clear viewfinder. After installing the new 21M viewfinder, it is very easy to recognize the focus with the naked eye when performing manual focusing. For users who like manual lenses, it is more convenient to control the depth of field.
The so-called filter magnification refers to the ratio of "the size of the subject seen by the naked eye" and "the size of the subject seen by the Finder". If the size of the image seen by the Finder is the same as the size seen by the naked eye , The filter magnification is 1x. If the magnification number is less than 1, it means that the Finder image is smaller. The above is the value when the device is in a standard lens (35mm conventional camera is 50mm lens), the field of view is set to standard, and the shooting distance is infinite. If it is a 35mm single-lens camera, it is 0.7-0.84 times.
If the digital single lens is converted to the specifications of a 35mm conventional camera, even the high standard Pentax *ist DS2 (Finder magnification 0.95 times) or Nikon D200 (Finder magnification 0.94 times) is only 0.63 times, while Canon EOS 20D (0.9 times) Equivalent to about 0.56 times, Canon EOS Kiss Digital N (0.8 times), Nikon D70s (0.75 times), etc. are about 0.50 times. Compared with the 35mm traditional camera, it is really a little powerless!
