Our take on the Kase 200mm f/5.6 MC Reflex Mirror Lens Sony E

The Kase 200mm f/5.6 is a compact catadioptric mirror lens for Sony E-mount cameras. Mirror optics fold the light path, so a 200mm lens stays short and light, but the design fixes the aperture at f/5.6 and gives manual focus only. It is a niche lens for reach on a budget rather than a general-purpose telephoto. At $349 at B&H Photo-Video-Audio as of November 4, 2026, it sits at the low end of what the three stores listing it new charge.

Questions and answers

Is the Kase 200mm f/5.6 worth it?
It is worth it if you want 200mm reach for little money and can live with manual focus and a fixed f/5.6 aperture. For action, low light or critical sharpness, a used autofocus telephoto is the better buy.
Does it autofocus on a Sony E-mount camera?
No. It is manual focus only, so you focus by turning the ring and use focus peaking or magnification on the camera to confirm.
Can I change the aperture?
No. The aperture is fixed at f/5.6. You control exposure with shutter speed, ISO or neutral density filters.
Why do the out-of-focus highlights look like rings?
That is normal for mirror lenses. The central mirror obscures part of the light path, so blurred points of light render as donuts.
What is in the box?
Expect the lens and caps; check the listing for a hood or filters, since mirror lenses often use drop-in rear filters rather than front screw-on ones.
When is it cheapest?
Mirror lenses are niche and rarely discounted deeply. Watch for seasonal sales at the three stores listing it; the current best is $349 at B&H Photo-Video-Audio as of November 4, 2026.
