I started out searching for a set of extension tubes to add some macro capability to my newly purchased Pentax K-x. After the requisite Googling I found not many of the tubes would pass through the aperture information which is a feature I'd like, and the only ones I could find were not no longer made and not available. In my search I came across some forum posts talking about this Vivitar TC and it seemed like it does just about everything I want. It magnafies your image 2x, so the SMC A 50mm I use with it becomes a 100mm. It also goes down to 1:1 which is considered "true" macro (meaning the image cast on the sensor is actual size). There were a couple on eBay and I scored one for about $75. For a macro hobbyist it's great.

Here's a flower:

These adapters are also no longer made, so eBay is your friend (or maybe KEH). Also be sure to get the one that says "P/K-A R-P/K" to be able to pass aperture info between the lens and camera. 

I have the honor of being the March featured artist at the Gunnison Gallery. I've had requests from friends and family away from here to post the show online. So here's my show. If you are in the area come see it! Anne at the gallery has done a wonderful job of mounting my work and assembling it all.

All of these photos are available for purchase in any size from 5x7 to 20x30. You can get them framed, dry mounted, or matted. Contact me for a quote if you are interested.
