I have one of these- a 500mm "equivalent" (https://www.amazon.com/gp/product/B004WLEEHI) and it's definitely got weird optical properties.

What Amazon says

ADVANCED OPTICS - Featuring an optimized design, this lens uses mirrors and a series of 7 optical glass elements in 6 groups to reduce chromatic and spherical aberrations. A anti-reflective coating suppresses lens flare and ghosting for increased contrast and color fidelity.
SUPER RANGE - Manual focus 500mm or 1000mm with the 2x converter, this lens is not only a superb long range choice, but also performs well in a variety of scenes from sports and surveillance to everyday shooting.
SOLID CONSTRUCTION - Full metal body and rear mount allow this lens to withstand wear and tear much better than plastic lenses while commanding a rugged, solid feel when using.
COMPACT AND LIGHTWEIGHT - Mirrors allows this lens to be much shorter than it would need to be without the mirrors. At 4.7-inches long, this 500mm f/6.3 is one of the shortest telephoto lenses currently available.
COMPATIBILITY - Can be used on all Canon EOS EF-Mount full frame and APS-C cameras including 90D, 80D, 77D, 70D, 60D, 50D, 40D, 30D, 20D, 10D, 7D, 6D, 5D, 1D, Rebel T8i, T8, T7i, T7s, T7, T6i, T6s, T6, T5i, T5, T4i, T3i, T3, T2i, T1i, SL3, SL2, and SL1.
