I have a few lenses from "ye good olde" analog days , amongst them a Tokina ATX 35-200mm lens, a cutting edge zoom-lens, when I bought it in 1982.

Browsing this forum has made me afraidof putting it on my K20D, or should I rather say "fixing" it, as it seems that some lenses got stuck, thus terminating the interchangebillity.

Is it safe use the Tokina ATX 35-200 with the K20D ??? (I shall refrain from the obvious ways to find out !!!)

I'm aware that the subject allready has been discussed, -and explained and enlightenedby Kjell, see tread below:

http://forums.steves-digicams.com/fo...mp;forum_id=94

But I'm never the lessstill in the dark, as how to recognize alien andhostile occupator-lenses.

With the LBA and Lens-Archaeology rampant in this forum, I guess that a general guidance would be usefull to others as well.

Kind regards

Ole

Hi Ole,

The modification that that Kjell was referring to is listed on this page ...

http://www.robertstech.com/flange.htm

If you have a lens with this elongated protection flange, you have no worries at all as the presence of that flange will stop you mounting it on a digital body anyway.

I have a Chinon zoom lens modified in this way it mounts no problem. Hope this helps ... Jack

Get a cheap teleconverter such as a 2x Focal brand bought for peanuts and use it to try out the lenses you buy before putting them on your camera. If they fit the tele then they should fit your camera. I keep one around just for that purpose.

Good idea Mr Dawg but the teleconverter wont protect against the Ricoh pin that jams the auto focus drive.

To jachol, Esquire

Thank You for response, I've found the links most usefull in my present predicament, but also a very good read in general.

I have the joy andpleasure of announcing, that at 17,15 DST the Tokina atx 35-200mm was joined with the K20D, and that the ATX din not take possession of my body, as they in full accordance with all parties involved, did separate at 17,16 DST !



@ Misters Dawg & Hill

Thank You also for Your input !

Allow me to say, that the way in which You Gentlemen exchange points of veiw, with suchdelicate grace and goodmanners is MOST inspirational.

Thank Ya'll

Ole

P.S.: My Tokina RMC's are just as agreeable sepatationwise.

Ole, you'll find almost none of the raving and name calling that goes on on most other forums. We all try to get along and freely pass information to each other. Even when we disagree we try to do it in a friendly manner and occasionally we agree to disagree. Glad they were a fit and looking forward to some photos with them.
