Hi Cotty
whatever a "Schluck" is, I liked your report.
You where to polite to tell us which solution you find better overall, yours
or Rolfo's.
Have fun with your new adapter.
greetings
Markus

>>When I came across Mr. Rolfo's adapter, I was very curious as to how he'd
>>solved the problem, and the only way to see for myself was to get hold of
>>one. 65 Euros later, one arrived in a small jiffy-bag.
>>
>>The adapter is quite nifty, and is based on an M42/EF adapter that can be
>>had from most photo shops, and eBay:

>>
>>As you can see, the M42/EF is a simple adapter that allows a screwmount
>>lens to be inserted into the middle of the adapter, and then the whole
>>thing mates with a Canon bayonet camera.
>>
>>Mr Rolfo's EOS-K mount adapter has been machined directly from one of
>>these screwmount adapters, and the machinist has done a reasonable job.
>>Because the K mount flanges and the EF mount flanges are only 'out if
>>sync' by a few millimetres, there is some interesting metalwork, and in
>>places it looks quite thin. But once mounted, it does the job and holds
>>the lens in place well, complete with a grub screw to prevent the adapter
>>un-mounting itself. So the idea is that once on the lens, you leave it
>>there, and it become part of the lens. If you had 2 or 3 lenses, you'd
>>need 2 or 3 adapters. It is possible to change the adapter from one lens
>>to another, but becomes moot with a further mod to the lens that is
>>required - more on this in a moment.
>>
>>In fact, when I first mounted the adapter onto the lens (a test-bed K50mm
>>f/1.2) and attached to a camera, it was out of whack by half a turn - so
>>that the aperture and focus registration marks on the lens barrel were
>>underneath somewhere and not on top as expected. I thought Mr Rolfo had
>>sent me a dud, and to be fair he replied to my enquiring email very
>>quickly, offering a full refund if the unit was bad. He sent some
>>mounting guide pics and a PDF. His english is not the best, but I used
>>Babel Fish to translate his German and that worked very well.
>>
>>In fact, it was me who was the dud. I had placed a K mount on the K50 1.2
>>but could only lay my fingers on 3 screws (too butt-lazy to go get some
>>more screws in the next room!) and lo and behold, even though I thought I
>>had lined up the K mount onto the lens correctly, it was out of kilter by
>>quite an amount. Once the K mount was re-attached at the correct
>>orientation, of course Mr. Rolfo's superb German engineering fitted like
>>a glove. They don't say Vorsprung Dirch Technik (or whatever it is) for
>>nothing.
>>
>>Naturally I apologised to Mr Rolfo forthwith and took back all the nasty
>>things I said about his lathe.
>>
>>To anyone who hasn't got a clue about using an adapter like this, it
>>means savaging the Pentax lens - this is Peter Alling's favourite part.
>>The aperture lever (the short metal post that sticks out of the back of
>>any K mount lens) has to be completely removed, or shortened so it
>>doesn't protrude from the back of the lens, as there's nowhere for it to
>>reside inside an EOS body, and nothing for it to do even if there was
>>room. So once a lens has been modified like this, it will either work on
>>a Canon camera with Mr. Rolfo's adapter, or on a Pentax camera without.
>>Both cameras will only be able to use stop-down metering with the lens,
>>in manual or aperture-priority. Open-aperture metering is lost.
>>
>>I haven't posted the detailed pics of the mount that Mr Rolfo sent me, as
>>they are his copyright, but if anyone wants to see them, I have 3 jpegs
>>of about 85kb each that I can send you. Email me off list.
>>
>>That concludes this presentation and if you've read this far then you're
>>a worse schluck than I thought you were! I now return you to your
>>regularly scheduled programming.....
