If you use this Adapter with a 50mm f/1.7 or f/1.4 MF lens you have a very good 85mm f/2.8 AF Portrait lens How much do they cost?
The AF with a 50mm is quite fast and with the lens set to INF it covers the full range without needing to manual focus at all.

These two OOC JPG 100% crops were taken by screen grabs of a comparison between the 1.4x HD TC and the 1.7x Adapter.
DA*300mm f/4 WIDE OPEN lens on K-5 100ISO Flash at f/5.6 and f/6.3. No PP applied.
The 1.7x Adapter transmits the aperture correctly to the camera. The image is about 20% bigger. The 300mm needs manually focusing to approx. the correct position before the shot.
With setups of 420mm and 510mm it's difficult to get shots that are in focus and without shake. From these results, especially taking into account the extra focal length (510mm) provided by the 1.7x I would say that it's slightly sharper than the 1.4x HD. Perhaps I should keep it
EDIT: Sorry the forum software has reduced these from 1024 pixels wide. They aren't as good as the originals.

The Super-A Manual shows the bottom on one shot and that hasn't got a cover.
EDIT:
None shown on the parts diagram or in the catalogue..

The DSTE charger is also worth buying. Shows red when charging and green when charged.

I've also used it with the DA*300mm f/4 on a K-5 without any problems. I've now got the HD DA 1.4X that I use instead. The 300mm needs stopping down to f/5.6 with that to get the best results. The 1.7x was good at f/4. There's very little difference in performance with all the top TC's they are very close to the maximum possible resolution. See .....

You sometimes have to set the focus manually in the vicinity of the subject for best results.
Edit: I forgot to mention Payment by Paypal gift or Bank Transfer preferred.

I no longer use this rare and unusual adapter, so due to it's rarity I'm offering it for sale to someone who is looking to give one a good home.
Virtually unused in Excellent condition, almost Mint apart from some very tiny marks (almost invisible) on the bayonet where it has been attached to camera and lens. The bayonet is in excellent condition. Even the pass sticker is intact and mint.
The internally focusing elements work perfectly.
Acts as a TC and also converts Pentax KA and K manual lenses to autofocus. Retains all exposure modes supported by the attached lens.
Can be used with Autofocus lenses, in which case the Adapter takes over the focus duties.
Complete with case and both original end caps. No box.
Focal length is not transmitted and has to be entered manually after multiplying by 1.7x.
Manual:

UK ONLY PRICE INCLUDING NEXT DAY RMSD £210



Edit: Seems to be a blue cast on the case. It should be black. Sorry.

It will also detect scene changes.

From the Manual (translated)
"Save Image Sequence":
With the help of this function, all images of an
AVI file can be saved as BMP images (since only
BMP images can be exported at this time, a lot of
hard disk space is required for larger AVI files).
When the corresponding button "Start" is clicked,
a file selection dialog opens, in which one or
more AVI files can be selected. Then a second
dialog opens, where the target directory can be
selected. The generated BMP files are stored under
"Original file name + name add."
