1000mm · f/10
The MC Rubinar 1000mm f/10 is a Russian-made catadioptric (mirror) lens with a fixed aperture, offering a compact and relatively lightweight super-telephoto option. Its optical strengths include suitability for creative and astrophotography, with improved anti-reflective coating and macro mode. Weaknesses include fixed f/10 aperture requiring ND filters, shallow depth-of-field, and characteristic donut bokeh. Build quality is metal, milled from a workpiece for stability. It suits specialized users like astrophotographers or those needing extreme reach in a portable package.
