nothing wrong with high magnification macro, but its not general purpose macro which includes both high and medium and lower magnification work.

I shoot snow crystals with a 50mm on a bellows, reverse mounted lens preferred. Those crystals are a lot smaller than a camera. Who'd want to take a macro picture of a camera? > On 2/13/2012 1:45 PM, JC OCONNELL wrote: >> 50mm lenses are way too short to use on bellows, they only allow >> super high magnifications, general purpose macro is out of the >> question with them, thats why most dedication bellows lenses are >> 100mm not 50mm. You are right on that, but there is no need to use bellows for any general purpose macro shots. >> -----Original Message----- >> From: [email protected] [mailto:[email protected]] On Behalf Of P. >> J.

I've used an SMC M50 1.7 for snow crystals and it has been good, better than my sample of the A 50 1.4 and better then the M 50 F2. But it was not as good (by far) as the M 50mm f4 macro. The SIgma EX 50mm f2.8 is also better. The M 50 f4 is probably the best macro lens I've used for extreme magnification, but it is dark and hard to focus on a foot or so of extension. - MCC -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions. -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
