High Peformance Reducer for 0.77X for AX103S and VC200L Optical Tubes
The reducer HD is compatible with the AX103S and VC200L optical tubes, reducing the focal length by 0.77x.
¦ Compatible with AX103S and VC200L Optical Tubes
The AX103S Optical tube incorporates a flattener lens and outperforms high imaging capability even by itself. From this reason, the Reducer HD can be used wihtout using the SD Flattener HD.
The AX103S covers an imaging field of DSLR camera with full-format sensor with 44mm image circle.
Originally incorporating a flattener lens insdie, the VC200L optical tube offers high imaging capability by itself. For this reason, the Reducer HD can be used wihtout using the SD Flattener HD together.
The VC200L delivers 36mm image circle (peripheral illumination by 60%) fully covering an imaging field of DSLR camera with APS-C sensor, and also offers comparably sharp images with the center in spite of 47% peripheral illumination at dia. 44mm image circle. It covers an imaging field of DSLR camera with image circle of dia. 28.8mm with APS-C sensor and dia. 44mm with full-format sensor.
Extraordinary High Contrast
The same anti-reflective AS coatings, which are used for our high-end VSD100F3.8 Astrograph,are used to take advantage of 99.9% superb high transmission of light per lens surface. Loss of light, ghost and flare images are eliminated substantilly due to the complete matte finish inside.
Applicable with SD-series optical tubes in combination with optional SD Flattener HD Kit.
In combined use with the optional SD Flattener HD Kit, the Reducer HD can be used with the conventional SD81S, SD103S and SD115S optical tubes. While maintaining an image circle of 44mm diameter, focal distance will be reduced by 0.79x (f/7.7?6.1). Extraordinary sharp image is available over the entire field of DSLR camera with full-format sensor.
