This is a Tamron SP 90 mm F/2.5 macro lens [the later 52BB model) with Adaptall-2 mount that comes with:
Extension tube 18F, allowing a 1:1 reproduction ratio (1:2 without) - boxed with front & rear caps, and owner's manual.
Tamron Adaptall-2 P/KA mount - this allows the lens to behave just as any other P/KA lens, so all metering modes are available. Works fine on Pentax digital bodies. This one replaced the original rather flaky one, and it has worked without issues.
Original lens hood 98FH (Bayonet fitting, over a 55 mm filter ring).
Original box (tatty!) and semi-rigid case (excellent condition).
The lens is in excellent condition. The optics are clean & clear with minimal internal dust. The aperture works well and the focussing is beautifully smooth. The P/KA adapter works well, allowing selection of apertures from F/2.4 to F/22. cosmetics are excellent, with just one bright rub mark on the bottom front edge of the barrel where the lens presumably has been resting on something.
Image quality is superb - sharp and high-contrast, with negligible distortion and no obvious chromatic aberration on an APS-C sensor. The lens is well-built and light (460 g) too. The only reason I replaced this is that it's a fiddle taking the 1:1 adapter on and off to get either side of 1:2, and much of my insect photography is done in that sort of magnification range.
Price: Looking for £110 to include UK postage. If it doesn't sell here I'll probably split it into lens, tube and mount and put them on Ebay, so I might consider splitting here.

One of Pentax's best 35mm AF film cameras, now sadly redundant due to the relentless march towards digital. Any film users out there looking for a bargain?
The camera has been well looked after and is fully functional, and comes with a strap, manual, body cap and a brand new battery.
Priced to sell at £40 + postage, but I'm happy to consider offers if you think I'm way off the mark.
