Where did you find a Kiron 105mm f/2.8 macro???? I understand it is made for Nikon, is that right? So what do you need to get it work on a Pentax? Thanks...

It wasn't made for nikon, but Kino Precision was originally formed by a group of engineers formerly employed at Nikon, who had developed their own designs for 35mm (24x36mm) film format camera lenses. These lenses were offered in a variety of camera mounts to fit a number of different Japanese cameras, including Canon, Contax, Konica, Minolta, Nikon, Olympus, and Pentax. (got this from wikipedia )

Later vivitar bought the designs for the 105mm and marketed it, as the Vivitar 100mm f/2.8 macro and the Vivitar 105mm/2.5 (1:1) macro lenses.

The quality of the lenses made by kiron was as good (or better) than the lenses made by the camera manufacturers but they couldn't produce them for the price of the others. So they disappeared.

I was just lucky to get this lens some years ago from someone who had bought it but never understood that he had to push the button on the lens to switch it to automatic aperture mode. He was just selling all his (old) equipment because he wanted a real (p&s) camera.

Lovely set Ronny - especially the bee on top of the flower and the 5:1 macro (no idea what it is other than some type of flower) !

I have no clue what the super-macro is, but it's fascinating. All of them are wonderful shots - Kiron made very nice glass.

I have one Kiron lens that my father had bought somewhere along the way. It's got oil on the aperture blades and it's not worth getting fixed - you can buy ones on ebay for less than what it would cost to repair mine. But when I can get it to stop down it's very good. Not sure it's really better than the Pentax F70-210 I used to have, but its sharper than the 50-200 I used to have.

Thanks everyone,

the last picture is a spiderwort.
http://en.wikipedia.org/wiki/Tradescantia_virginiana
it's native to the eastern United States. I have had it in my garden since I bought the house but only recently learned its name.
(ps that garden is in Europe)

I was going to ask you how come a native US plant managed to be in a garden in Belgium. In any case, it's an interesting flower picture.
