Kase 200mm f/5.6 MC Reflex Mirror 200mm
Its catadioptric design delivers a 200mm telephoto reach in a remarkably compact 384g body, while the multicoated optical glass and fixed f/5.6 aperture produce a distinctive donut-shaped bokeh for full-frame Nikon F sensors. The all-manual, mirror-based construction eliminates chromatic aberration and offers a unique rendering at a budget-friendly price point. This lens is best for portrait photographers and outdoor enthusiasts who prioritize lightweight portability and creative bokeh effects over autofocus speed.
