I'm looking to add better close-focusing ability to the Sigma 70-200 F2.8 APO I just bought, and would prefer to keep autofocus and the same max aperture (i.e., I don't want to use the 1.4x extender or a macro tube). This seems to be the only two-element close-up lens in 77 mm. size, but it sure costs.
Has anyone tried it? Experiences? Thanks, Joe - This message is from the Pentax-Discuss Mail List. To unsubscribe, go to http://www.pdml.net and follow the directions. Don't forget to visit the Pentax Users' Gallery at http://pug.komkon.org .
