no, if it is 500mm mirror lens, it is about one third the size or smaller of a normal 500mm lens.meaning a 400mm lens with the mirror system can go to 800mm focus length?
may i noe where to get those lens ?
You also lose the auto-focus of your camera, as most AF modules to not work properly beyond F5.6. Lastly, mirror lens do not have good bokeh. Instead of a nice, smooth blurred background, you get strange, circular donut shaped highlights. This comes about from the internal mirrors used in the lens body.
It's auto-focusable also ;pI guess the only mirror lens that is sold new by a major brand is the Sony (Minolta) 500mm F8 mirror lens. Available at most sony outlets. ;p
Mirror lenses typically have fixed apertures, typically between F8 to F11

You may wish to consider the pros and cons of mirror lens before getting it. Getting reasonably sharp pic (subject to good lighting and steady hand/support) is attainable, but it would definitely not be comparable to the telephoto prime lens.
Most are fully-manual-focus, and note also that you can't use your normal lens filters for mirror lenses. You need special ones that fit to its mount-side.
This is the 600mm Sigma I own. It's for the Canon mount. I think it has been discontinued....at least, I don't find it anywhere in the Sigma website.
Pretty compact length wise for a 600mm, but a real fatty in bulk
