From the Manufacturer:
The Sinaron Digital CPL line of lenses, which are equipped with the well proven mechanical Copal between-the-lens shutters, are operated fully manually; therefore no computer, software or electrical power is required to use them.Resolving Power
Sinaron Digital CPL lenses provide the photographer with maximum sharpness, high contrast and outstanding color fidelity. These lenses have a resolving power of at least 50 line-pairs per mm throughout the entire image circle. Sinaron Digital CPL HR lenses have even a higher resolving power of at least 60 lp/mm. In the center, these lenses may resolve even up to 200 lp/mm. This makes Sinaron Digital lenses best suited for high-quality, high-resolution images.Application
- Sinaron Digital CPL lenses can be used on Sinar p3, Sinar p3 SL, Sinar f3, and Sinar f3 SL view cameras.
- Sinaron Digital CPL lenses mounted on a 100 mm lens board are available in focal lengths from 28 mm to 210 mm.
- Sinaron Digital CPL Lenses are operated fully manually, no computer, software or electrical power is required to use them. That makes them ideal to be used in conjunction with the Sinarback eMotion with its on-board battery power supply.
With such a combination the photographer can take digital images with the same freedom of movement like in the “old days” – when film was the standard image storage medium. That means there is no hassle with cables, computers, or external power supplies. The well-proven mechanical Copal between-the-lens shutter of the Sinaron Digital CPL lenses provide exposure times of up to 1/500 second. The operation of the lenses is very easy and self-explanatory.
