Bought my 67II and lenses three years ago on eBay (which still is the cheapest place to get this sort of equipment). Never have had a problem. The seller has to be reliable (which you can read thru the lines in his feedback), the body in mint condition and all lenses have to be scratchfree, without dust or fungus. Also bought a flawless Fuji GX680III on eBay.
Get a good tripod. Get good focus screens and some additional accessories and you are all set.

This is a very rare and strangely built lens. I sure wish I had the cash to pick it up.

Don't wish too hard. You really think you'd haul that monster around when you could get nearly the same focal length in 35mm format lens that can do the same job, yield the same results, doesn't require stop-down metering and one you might be more receptive to carrying around?

Fl_Gulfer, you haven't told me what the weight is of that behomoth? For a moment, I thought I was looking at a 70s-era satellite...
It surely wouldn't be a bantam-weight thing. I suspect I would need to hitch a trialer to my car if it were attached to the already bloated and beastly 67 or 6x7.

I've only seen three or four 1000 mm mirror lenses for sale over the years and never in this nice of condition. The real monster of the lens line is the 800 Takumar at 39 Lbs.

mirror lenses make strange out of focus "donuts" and the mirrors are far less stable than glass optics in the long term..........

This is what one of our Forum members wrote about the lens :

"This post is a review for informational purposes, as I don't own this lens. The 1000mm Reflex-Takumar is probably the rarest lens for the Pentax 67 system. There is also very little information about it. This mirror lens has a 7 inch diameter and weighs just slightly more than the 600mm f/4 Takumar; not bad for a 1 meter focal length lens. As one would expect, it is for use on the outer bay of the P67 lens mount. There is no diaphragm, which is typical for mirror lenses. It is set at f/8 which is determined by its optical design. I have a background in optics and I must say that I have never seen a design like this lens. It is obviously a Maksutov Cassegrain from the telescope world, however it does not resemble any known type in that category. Instead of having a meniscus up front as the first element, it has a weak positive element, followed by a meniscus. The slightly converging light beam reflects off of a concave mirror (probably spherical) and then to the secondary mirror that is attached to the meniscus. From there, light is passed through a hole in the primary mirror and through the rear lens group. There are two mirrors and seven refracting elements. Focusing is done via large knobs, just like the 600 Takumar. This lens comes with built-in ND, Skylight, Y2 and R2 filters that can be rotated into place. Exposure can only be changed by the ND filter and shutter speed, since this lens has no diaphragm. Because of this, DOF changes are impossible. This lens is best suited for narrow focus subjects like birds or mammals at distance, although certain near infinity shots could be had as well. Since Pentax has stopped producing these lenses, I have only seen one for sale on the used market. The price of this lens when new was $5900. US."

$5900!? And...what!? 6.5kg!?
Lemme see: Pentax 67 with...hmm, TTL prism and a roll of 120 loaded, yes...hmm... that would be nudging close to a 10 or 11kg kit with this mirror lens on it? Seriously, what is needed to carry such a get-up around without offloading cash in the chiropractor's rooms? That f8 would result in a mightily dark viewfinder in the 67s; it's often bad enough at f5.6.

I had a 500mm mirror lens I think way back in 1985, and used it for just 7 frames on an Olympus OM4 before I got jack of the bulk, weight and strange looks, to say nothing of the patently lousy image quality. I think it was a Tamron CAT lens with Adaptall mount, but cannot be sure from memory now and that experience unfortunately put me off those "innovative" lenses for good.

The reason these mirror lenses were produced was because years ago, refracting elements caused too much CA in long focal lengths. Mirrors do not cause it. So, Pentax opted for mirrors instead of glass in this long focal length lens. But, with the advent of low dispersion glass, colors could be controlled without the need for mirrors. One of the results was the 800 EDIF and its 1.4X converter. ...and yes, I wrote the review above on the 1000mm Reflex.

Thanks Desertscape...
But is the lens worth EUR 600 euros = 777.4200 US dollars With the adapter for "K" mount?

Or is the M42 Asahi Pentax Tele-Takumar 8/1000mm worth 800 euros = 1036.5600 US dollars?

That is the opening bid for both lenses

800 Euros is a good price for the T1000/8 lens, it's close to mint and has the trunk. WestLicht had the K-mount version last auction and it sold for 1080 Euros. (same starting price of 800EUR)
I have the K1000/8 and paid around the same price. (1080.00EUR = $1400.00CDN)

The 1000mm Reflex lens at $777 is a steal, especially since it appears to be mint. If I didn't already have long lenses for my 6x7, I would be interested in it.
