Hahnel Samyang Mirror Lens - 500mm, f6.3Incredibly compact and lightweight, mirrors lenses are a cost-effective alternative to traditional fixed focal length telephoto lenses.
Mirror lenses are not new - they've been around for a long time - however, recent advances in optics and coatings have brought about considerable improvements in the quality of images they can produce. Samyang are one of the world's leading developers and manufacturers of mirror lenses.
That said, it is worth bearing in mind that mirror lenses do not have any built-in image/optical stabilisation, and have a relatively small aperture. Consequently we recommend the use of a sturdy tripod if shooting in anything other than daylight conditions - or a willingness to bump up the ISO to help reduce camera shake if shooting hand held in poor light!
These lenses attach to the camera via a T2 mount - if you do not already have a T2 mount, please remember to order one when ordering your mirror lens.
