Tak abych take ja obcas aspon trosku prispel do debaty, tak jsem se zeptal primo toho prodejce. Juknete na to a dejte mi vedet jak tomu rozumite Vy. Ja si myslim, ze by to mohlo s K10D, K20D fungovat spravne. Uvazujete pripadne nekdo o tomto konvertoru ?

Subject: Kenko AF 1,5 x Telekonverter Converter Pentax PK AFIII
Hello Jochen,
At ebay (
http://cgi.ebay.com/_W0QQitemZ160320620044QQ,) I have found above mentioned converter and I would like to ask you.
I have Pentax K10 and would like to use the convertor with my new lens Pentax SMC DA* 50-135mm F2.8ED (IF) SDM
You have written that the convertor has been tested with K20 (sholud be same like K10) but with which lens have you tested ?
On pentax forums I have red reaction of users that they have tried convertors from soligor, sigma etc. but autofocus did not work, in automatic regime.
Also what does "works on weak AF lenses as well mean" ? Also you have in your specification silent wave lenses are working - does it mean SDM/HSM works?
I just would like to ensure that autofocus and SDM/HSM works with this Kenko AF 1,5 x Telekonverter Converter Pentax PK AFII
I wanted to buy new announced 1.5 Pentax convertor but it is still not available on market. It seems to be at the end of this year in europe (unfortunately europe is small country for producers....)
I am from Prague / Czech Republic, pay pal account owner so there should not be any problem in case I decide to buy it.
Hello,
Sorry the answer comes a bit late...
I´ve testet the lens on K20D with the Pentax DA* 50-135mm and 35mm 2,8 Macro on K20D and K10D.
On the K10D it will work as well.
A customer of me has tested the Converter with 17-70mm Pentax and the auto Focus is working as well.
He said that this lens don´t have the the Auto Focus mechanism any more ... so the SDM/HSM must work and not
the " old " mechanic Conection..
The Coverter got the Power Focus Conections and because of that the HSM Motor is fully functional.
" Weak lenses " I call lenses with apertures less than 5,6 . With a Converter you lose light.
With a 2x Converter a 5,6 lens will be 16 .
The the Exposure automatic will not working correctly most of the time.
With this Converter you only lose 1 Apperture step.
I testet as well lenses like Pentax 35-70 3,8-5,6 and it is working as well.
If you have more Questions just send me an e-mail...
Best regards...
