About the only disappointing thing about my experience with the Pentax 645 I purchased this year has been my lack of any means of doing any macro photography. Before buying extension tubes or a macro lens I thought I'd try an achromatic close-up "filter". So last week I scored a 58mm Sigma 2-element achromatic close-up lens on eBay. $26.00 including shipping (from England!) seemed like a cheap way to experiment, even though I'm loathe to put anything between the front element of my lens and my subject. In my brief trials this afternoon (sans film) I've determined that I can get pretty close with my 75mm lens and probably very near 1:1 with my 200 (and the Sigma is supposedly optimized for longer lenses). Now it's time to shoot some film and see what it can do :-) Mark - This message is from the Pentax-Discuss Mail List. To unsubscribe, go to http://www.pdml.net and follow the directions.
