Re: Cheapest Pentax Extension Tubes
When you buy extension tubes, you get a set of three, so your figures add up nicely...:-) My set of Chinon tubes cost me $25 a few years ago. Include Ricoh and all the 3rd party makes, and you add up with pretty decent odds for finding something second hand, in good shape, and cheap. Why do you want AF? On extension tubes, it sounds pretty wasted, imo... Jostein - Original Message - From: "Gregory L.

Re: Cheapest Pentax Extension Tubes
My theory is that they do all of than then simply discard the lenses. That would account for the cost. ;) At 09:36 AM 2/11/2003 -0500, you wrote: Inspired by the best and cheapest lens thread, I was browsing lenses on B&H, and saw extension tubes listed.

Cheapest Pentax Extension Tubes
Inspired by the best and cheapest lens thread, I was browsing lenses on B&H, and saw extension tubes listed. And it looks to me like the cheapest Pentax AF extension tube is the Tamron 1.4x teleconverter with lens removed, for $50. The tubes without lenses cost around $150. What in the world is up with that? Does it really cost that much more to *not* grind, polish, coat, and install glass? -- "A nice adaptation of conditions will make almost any hypothesis agree with the phenomena.
