SMC Pentax-A* 645 600mm f/5.6 ED (IF) lens - final price drop - $3000

PentaxForums.com Marketplace Listing

Item for Sale
SMC Pentax-A* 645 600mm f/5.6 ED (IF) lens

Asking Price
$3799.00 USD

Item Location
Livingston, Montana (United States)

Item Description
SMC Pentax-A* 645 600mm f/5.6 ED (IF) lens

Utilizing a Pentax 645-A mount this manual focus, automatic aperture lens fits and operates fully on all Pentax 645 medium format camera bodies, including the latest 645D digital body, for which its extreme resolution is a perfect match. On a 645 format body it is comparable to a 360mm lens on a 35mm film body, or, roughly, a 540mm lens on the current Pentax DSLR cameras (K-5, K20, K-r, K-7, etc.). With the Pentax Adapter K for 645 lens mount adapter it can also be used on all past Pentax 35mm K-mount bodies and current Pentax DSLR bodies.

Very rare and no longer made, this top of the line "star" series lens was the longest focal length and most expensive lens made for the Pentax 645 camera. Essentially hand-built to the most exacting tolerances and utilizing the most advanced telephoto optical technology, including extra-low-dispersion (ED) rare earth glass and internal focusing [IF], this was arguably the sharpest, lowest aberration, best performing lens available for the 645 camera. It is also built like a tank.

This particular lens, Serial Number 4053449, while used was never abused. Great care was taken when using it, which is reflected in the fact that there are only a small handful of tiny paint chips missing. Four tiny and barely visible on the handle, a small chip and very minor scuff marks on the tripod foot (see photos). Other than that the lens is in essentially mint condition. Glass is flawless and like new, including the protective 128mm PF filter that protects the rare earth front lens element. This optically clear filter is designed to act as part of the overall optical system, so, although it can be screwed off, it should be kept on at all times. Mechanically the lens is also flawless, and all parts operate exactly as when brand new.

Focus is velvet smooth and razor sharp at all f-stops across the film/sensor plane, with virtually no color fringing or chromatic aberration, and, with the Pentax patented Super Multi-Coating, very little lens flare even shooting directly into the sun. Bokeh is buttery smooth. Contrast is crisp. Color transmission and fidelity is Pentax faithful. In every parameter, on a scale of 1 to 10, this lens is a 10. For a comprehensive member review (not mine), including all specifications, see the forum Pentax Lens Review Database - Pentax 645 Medium Format Lenses - 645 Telephoto Primes.

All the parts that the lens came with - front filter, front soft vinyl lens cap, rear hard plastic lens mount cap, drop in filter holder, lens strap, lockable aluminum hard side lens case with original keys and key holder, and instruction sheet - come with the lens (see photo). The only thing that shows any normal wear is the lens case itself, which, as one would expect for a lens used professionally, shows dings, minor dents, and normal travel scuffs. However, it closes smoothly dust tight, locks easily and holds the lens securely. See photos for all the above.

I loved the pictures this lens made and hate to part with it, but, like all my 645 stuff, I am liquidating it because I am semi-retired and no longer shoot commercial advertising and corporate work, so have no need for it. I am offering it here exclusively before putting it up for auction on eBay so that forum members, fellow Pentax lovers and Pentaxians, have first shot at it.

Here I never knew the hood extended double on mine. Go figure. Was a pretty rare lens for a while but now you are starting to see a few more show up now and again. Anyways just browsing hoping you had the drop in polarizer...

While it has a drop-in filter holder, it didn't come new with any filters to fit in the holder, which takes standard screw on 49mm filters from any supplier. The only filter that came with the lens when bought new was the front 128mm optically clear filter to protect the front lens element, which I believe is delicate coated flourite glass. I used a variety of 49mm Tiffen filters in mine, including a 49mm Tiffen circular polarizer.

As for the the two-stage lens hood, I think many people who bought this lens used have not known that it would double extend. Only original owners like myself, with the original instruction sheet, were well aware of the fact. I used it alot, since much of my shooting was backlit, at some angle into the sun. The double extendable lens shade, something I don't remember seeing on any other lens, is a terrific feature of the lens.

Great lens. Perfect for 645D camera. Can work on all Pentax cameras, with right adapter. Here first, eBay later.

Not only does this lens work well dn a 645 but equally well on a a Pentax DSLR with the adapter. I have both this and the 600"A and prefer this lens over the 35mm version. CA is extremely well controlled on the 645 version. the handle mount is simply luxury in the field and the lens is relatively compact. Really wonderful lens.

Nope. Already own a "one of a kind" Chatham. Don't need more. Besides, Russell abandoned Montana to return to his roots in California.

Interested in your lens.

However, your decisive information for me: "On the former it becomes an approximately 1000mm f/5.6 lens, and a 1500mm f/5.6 lens on the latter APS-C sensor bodies." doesn't appear supported in instructions manual for the 645 to K adapter (I have): "Focal length and Angle of View: The figure below shows that the angle of view of the 645 150mm lens, that is 26 (Degrees), becomes 16.5 (Degrees) when the lens is mounted on the 35mm camera, just the same as the 35mm format 150mm lens."

600mm (645) appears to be 600mm on FF with the adapter as well. Can you please clarify (provide) source of info on becoming 1000mm with 645-K adapter (or 1500mm - 1.5 factor understandable just fine)? Thank you!

P.S. My simple observation with 645 FA200mm & 645-K adapter and K A*200mm (at 6 ft or 2 meters distance) yields 645 FA200mm has actually 5/8 wider coverage (10 3/4 vs 10 1/8") than A*200mm. That would point to 600mm being more like 560mm or so on FF. Thanks again.

O.O looks like someone just dropped it from outer space. Beautiful, and bloody massive by the looks of it. what a lens. Reckon you'd get a few funny looks from airport security with that…

Trapezoid645, I believe you are correct and I am wrong. I humbly stand corrected.. I have never really been very good at this kind of math. I think then, on an APS-C sensor camera, from what you say, the 645 600mm lens would be more something like an 840 to 900mm f/5.6 lens. Of course, it would be creating the image thru the best part of the lens glass - the center.

I have lowered the price by $101.00, to $3799.00

Thank you sir for clarification. And you are absolutely correct, cropped sensor takes nice advantage of center's sharpness. Thanks again!
