This is a GREAT point. If you use achromat (not your el-cheapo close-up filters) you can get some great results. Here's a handheld shot I made with a Pentax-F 70-210mm (non-macro zoom) with a 48mm Canon 450 screw-in achromat. Need a 48mm step-down ring to use it, but it was inexpensive (around $30) http://farm5.static.flickr.com/4065/4585315414_72f7c06a16_b.jpg I was awakened to the high quality of achromatic close-up lenses by John Shaw's amazing book: Closeups In Nature so a got a couple of older ones rather inexpensively. Some people say that the Canon 450 is an others that it is not an achromatic. I have two (both in 48mm filter size) and I think that one is an achromat and one is not! Both of these were handheld at the 70mm setting, but would have benefited from tripod mounting and perhaps use of the focusing stage. I hope to get time to play with them more on various lenses, such as the Takumar 135mm f3.5.
