The 500mm Telephoto Mirror Lens has a compact design that utilizes a combination of lens optics to refract and reflect light – the same physics used in many professional telescopes. Combined with advanced manufacturing techniques, the result is a lens with very sharp image quality and less color aberration, considered the most detrimental factor in telephoto photography.
Reflex mirror lenses utilize the principle of refracting light that is reflected twice before it hits the film, greatly reducing the size and weight of telephoto lenses and even creating a donut shape unique to mirror lenses.
For those who photograph wildlife, the moon or lotus flowers as a hobby, this lens will be a great choice.
Features:
1. Suitable for wildlife, landscape photography and astrophotography etc.
2. Manual focus, fixed aperture F7.5.
3.Multi-layer brightening coating helps to reduce ghosting and glare.
4. Provides the user with extremely sharp images with minimal color aberration.
5. Compact and lightweight design makes it easy to carry and use.
Note:
1. Due to the long focal length, it is recommended to focus in live-view mode to achieve accurate focusing.
2. As with all long telephoto lenses, a combination of a sturdy camera support, a reliable tripod, good technique, fast shutter speed, use of remote control and mirror lock to avoid camera shake is recommended for best results.
