- Catadioptic lenses. Mar 9, 2017. 1. Mirror lenses have had a bad rep since about the 1980s, but despite their low contrast slow speed, and doughnut bokeh they can be quite useful. I have both a Rioch 600mm f/8 & more recently an Opteka 500mm f/6.3 which get used more than many of my adapted lenses. I have a Sigma 150-500 which works well on my ...
Canon patents 400mm F5.6 catadioptric 'mirror' lens
- https://www.dpreview.com/news/3295932675/canon-patents-400mm-f5-6-catadioptric-mirror-lens
- A new Canon lens patent out of Japan has been raising eyebrows around the photo community this week. The patent describes a 400mm F5.6 lens, which wouldn't necessarily be newsworthy... except that it's a catadioptric lens (also known as a 'mirror' or 'reflex' lens).. Catadioptric lenses went 'out of style' so-to-speak many years ago, but for a time they offered …

What is Catadioptric telescope? Important Advantages …
- https://lambdageeks.com/catadioptric-telescope/
- Catadioptric telescopes are a variant of optical telescopes that form an image by combining specially designed mirrors and lenses. This telescopic configuration is intended to obtain a greater degree of error rectification overall compared to all-mirror or all-lens telescopes. The catadioptric design provides a wider aberration-free field of view.

- A catadioptric telescope is an optical system that is optimized for producing images of objects at an infinite distance, incorporating both refractive optics (lenses) and reflective optics (mirrors). Because both mirrors and lenses are used in catadioptric optical systems, the user obtains certain performance advantages over other types of scopes.

- Catadioptric telescope can be diffraction limited; as good as a optic can be. A common failure mode with a mirror optic is poor focusing; no hood used; camera shake; stray light; warped tweaked distorted mirror mount; due to abuse. . The better mirrors can be quite good on axis; but often drop off in resolution going off axis.
What does lens flare from a catadioptric (mirror) lens …
- https://photo.stackexchange.com/questions/95006/what-does-lens-flare-from-a-catadioptric-mirror-lens-look-like
- Because most catadioptric lenses used for photography have fewer refractive elements than typical refractive lenses created for creative photographic use, most catadioptric lenses demonstrate less flare than many refractive lenses used in creative photography. But what flare they demonstrate is caused by the same properties of refractive lenses as the flare …

- A 500mm lens and a step stool to peer over the fence. Also known as catadioptric lenses, or “cats,” some mirror lenses contain glass elements clustered together with no air between the elements. These are called “solid cats” and are shorter though notably heavier than their mirrored counterparts.
