Hello Fred & Mishka. Well, as I do not have an OM body here I cannot say if it requires a tube for 1:1 - the barrel markings don't suggest anything of the sort. Focusses in the opposite direction to Pentax.
This one is well used although all the mechanics & optics are good. We are selling it at GBP75. From memory the last independent macro we had of this type was the Kiron 105, which was just perfect & went for GBP120. Kind regards Peter - This message is from the Pentax-Discuss Mail List.
