    Default Did someone ever used mirror lens?

    ...does anyone have expirience with mirror lenses?
    Frend has M42 Rubinar 500mm/5.6 (only f5.6) lens in pretty good shape for cca 200$. For that money, I will also get 2x converter.
    With this converter and crop factor, it will give me 1600mm.
    Is it worth that money. Bundle also includes some 3 filters for sun and moon shooting (don's know specs).
    It looks like this:

    It has tripod mount ring at the bottom.
    I never even knew that something like this even exists.
    Please few advices, thx.

    These 500mm mirror lenses are available all over the place, including new ones:

    I don't know if the older Rubinar 500 5.6 is any better or worse than the others like it. Here is a post in a thread where the guy has the Rubinar 500 plus several others and discusses it briefly:

    http://photography-on-the.net/forum/...r#post10063166

    You can look around more in that thread for more thoughts about mirror lenses. Also try a search on this forum, because I know they have been discussed.

    For the money, they are fun, and easy to carry. I don't think I'd be putting a 2x converter on one, however. They are already pretty soft.

    I had a Minolta 500mm Mirror for a while. It was an fixed f8 lens, mostly worthless unless you are in harsh mid day sunlight. Also, tough to focus at f8 due to the low light.
    Sold it. Low contrast and soft photos where the main results.

    I've had one for over twenty years. I've used it maybe once or twice. I'd sell it, but it essentially has no value. It's better than nothing for what it was designed for... it's an inexpensive f/5.6 mirror telescope optic. If you keep that in mind it's fine. If you think it's going to perform as well as a brand-name 500mm optical lens, you're going to be disappointed. REALLY disappointed.

    Generically, they're fun to have and play with because of the long reach at minimal weight, size and price. In my limited experience only a few are capable of good image quality and the majority are not.

    They place a heavy emphasis on a good viewfinder and focusing screen. I literally cannot focus mine (500/8) through my E-510 finder, but can on the E-30 and E-5. Oly IBIS is a huge help, of course, if you want to handhold or use on a monopod.

    I don't know this brand--probably a generic house brand name made by one of the big optical houses.

    Cheers,

    1.6x crop factor? Are you shooting with a Canon APS-C camera?

    For real reach and an advantage in telephoto, get an Olympus camera. With a 2x converter and that 70-300 mm lens, or better yet the 300 mm f/.2.8, get 1200 mm equivalent focal length.

    Find a Tokina 400mm F5.6 SD instead. Excellent legacy glass for the money.

    The Rubinar 500 f/5.6 (exposes more like f/6.5 or so) by trusted reports (Jens Birch/Jebir) is a very good performer IF you are willing to get inside and relax the retaining rings on the optical elements. Most problems with these lenses are due to 'pinched' optics. Many of the old threads on this lens here are archived and I don't know how to link to them but if you do a search on Jebir and Rubinar you will get a few threads that should be of interest to you. The $200 price may be just a little high (used to sell for $230 new), but if you're the least bit handy and unafraid of tinkering around I would pick it up and give it a go.

    Also search for threads in the photos section by 3dpan (Alec) who has a 500 Rubinar that I believe he relaxed the optics on... some good results on his part also.

    I just don't think the cheaper mirror lenses have the optical chops to make them worth using (I have a cheap one and the optics are "meh" at best). That said, I don't know anything about the Rubinars. If I were going the mirror lens route, I would spend the extra coin for an Olympus or the latest Nikkor 500mm.

    Yup, I've used one, and I've still got one, a F8/500mm reflex. In fact, I've got two similar (not Rubinar) unused ones, in unopened packages, with a set of filters, and with a couple of different T2 adapters, if someone is interested. Hint hint, nudge nudge.

    Hard to say whether it's worth the money or not. Probably not. Looks like 200 Canoocki Dollah is about 153 €ugenes or 195 Obama Dollah. Not that bad, but not that great, either.

    The RF telephoto is indeed a bit of an oddball as a photo lens. They are short in size, usually quite light, too, but notoriously slow lenses, with no aperture, which means you're stuck with the full aperture, which is typically around F5.6 or F8.

    They can be fun on bright weather days, when shooting something hard to reach with traditional shorter lenses. You've also get a cool circular bokeh, which can be a nice effect at times. Or slightly annoying, too, depending on the picture and the viewer. The 500mm RF you've been offered would make a slow but lightweight telephoto lens equivalent of a 1000mm reach in the 35mm terms. It won't be a supersharp one, though.

    They are reasonably easy to use and focus even with a typical Olympus dslr or a PEN screen, provided that you're used to manual focus, the subject is far enough, and there's enough light to focus. F/5.6 is not that bad, but you'l still have to save it for the bright enough days.

    All in all they're sort of fun, sort of quirky, sort of useless, too, in many cases. So whether or not that's worth the 200 canoockians, only you can tell. I probably wouldn't bother. But then again, I've already got one as a 'toy', so...

    PS.
    The Rubinar is likely to come with a T2 adapter as standard, which in this case is a 42mm version. If you plan on buying the thing, you might want to check that out. If you plan on using it with a 4/3 or µ4/3 body, you might want to buy a (µ)4/3 T2 adapter (around $15), which you then screw in instead of that 42mm version. If you'd go for a (µ)4/3 m42 adapter instead, you'd end up with two separate adapters between the lens and the body, and focusing to infinity might become a bit funky. It may be like that with just one adapter, anyway, so you'd better be prepared for that. Harmless but slightly annoying.
    Canikon or Sonympus? -Who cares, as long as it works.

    You do NOT want to put a 2X converter on this beast! Even the best Catadioptric lenses were merely adequate. And this is a budget lens from the 'get-go'

    I have a Zuiko 500mmF8.
    You need a very high shutter speed to get a good result, and a good result is possible. I would not even consider a converter as well though. Atmospheric coditions become a factor and the combo with a 2x crop factor will be virtually unworkable.
    My Zuiko in fact is far better on my 1D3 with a 1.3x factor compared with my E-3 with a 2x factor.
    Cheers,
    Don

    But the same quality that creates the monsters above can be used artistically. See http://www.pbase.com/shootin/image/56276981 .

    I think a mirror lens could also be handy for unobtrusive long lens work where a big white lens might get you noticed.

    I've got a 600 f8 Tamron for OM that I've used a fair amount. On 4/3 it's a 1200 f8, of course, and absolutely must be used on a tripod or at least a monopod in anything but the absolutely brightest of light.

    Depth of field is fundamentally razor-thin, which makes it a hard lens to work with. When focused, it's sharp as a tack, but atmospherics (distortion due to heat effects, especially in the summer, but other times as well) can be very tough on imaging from these lenses.

    They are tiny, though. Makes a big difference traveling...
