SMC Pentax-F 1.7X AF Adapter with case : Excellent Condition

SMC Pentax-F 1.7X AF Adapter

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.

Algernon, does the TC work with the K1 and A lenses?

I've only got a K-5, but it's a FF Adapter and I used to use it with a Pentax-A*300mm f/4 on different bodies without any problems. The ebay price of these has shot up in Japan etc. (£300 - £380) so I would assume that's because of people wanting them for a K-1.

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.

Sorry, I'm not he, but yes it does. You still need to enter the updated focal length (1.7X)

I can confirm that mine works fine with the K1. Hope this helps.

Not a lot of people know this.........

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.

Originally this was a UK only sale...... but, because the item is small and I can also insure it I'll would be happy to post it also to Europe for the same price £210. Signed for delivery. Paypal payment as a gift

Would it be possible to see the comparison with the 300 with and without the adapter?

The loss is so little that you can't see it. That's true of most Top TC's. It's measurable in a lab, but probably less than 5%

I could use the case off this so if anyone wants it without the case I'll knock £10 off.

--

Reduced to £179 inc. postage as above to UK or Europe.

Take £10 off if you don't want the case.
