Hi Rick,
My apologies for not answering your request - I have only just found it. Both the Stereo Adapter D Set and 9005 are barely usable with PP. I use Stereo Photo Maker and have found that a fair bit of cropping is often necessary to get a usable image. Since Christmas I am using a Fuji W3 and the Pentax has stayed in in its case. I really should get it out and do some comparitive work!
I like the Pentax as I can simply wind it onto the lens - taking care to get it level and adjust the fl and I don't have to worry about putting a lens away carefully if I am in hurry to set up. The Loreo is bulky and has some serious colour fringing at the edges. I think the Pentax wins on sharpness. It is also easier to clean.
I do apologise again for the tardy and hastily written note. Please feel free to contact my off list petenkaye@skymesh.com.au as there seems to be few 3D-ers in the Pentax forum.
Cheers,
Pete

Greetings and please forgive me if the private message is a faux pas. You seem to be the one to talk to about 3d. I have the Loreo regular lens in a cap, and was thinking of upgrading to either the the newer 9005 version, or getting the Pentax version. I would appreciate any input.
I read of your issues the the 9005 with the 200D, but you never followed up with how it did upside down? Loreo now says the lens is incompatable with the 200D and it is a "tight fit" on my K20D. I found a place that sells the Pentax digital Stereo Adapter D Set in Japan, I would probably get the 35mm F2.4 to use with it. (with the 49/52 adapter)
I, like you inherited a love of Sterographs from my Grandparents, I have several hundred cards from the 1890's to the turn of the century.
Thank you,
Rick
