Macro Holy Grail (tubes)
Posted By: shooz, 03-03-2015, 03:53 PM

180833 Vivitar Extension Tubes for Pentax PK A Used | eBay

I have a set of these in Kenko version, that I bought here on the forum a couple of years ago, give or take.

This is the only other set with A contacts that I've seen since.

I hope someone here on the forum takes these magical beauties home..........

Well I was watching them... but I suspect now the price will be a bit rich for me.

i have tried to bid on a few sets of these and they always go for around $200, which is more than I am willing to pay for a set of tubes.

I have the Kenko branded version as well. They are a pleasure to use and meter perfectly with my K5.

I would like to add that the tubes in the listing appear to have the extra contact that not only allows for PKA metering, but also transmits lens information to the camera. So useful to know which lens you were using at a later date.

$70 with an hour to go.

With those contacts they will work with modern lenses that have no aperture ring.

I have the kenko set, but, I tend to use a gutted autofocus teleconverter more, has all the contacts and, macro autofocus, and heaps cheaper, you can pick up cheap 2x and 1.4x converters, doesn't matter what the optics are like, just remove them, and, presto, auto focus, with all the contacts extension tubes.
