It's kind of funny: This description of Sigma 70-200/2.8 (for Pentax!) says that the lens is "Optimized for Pentax Full-Frame DSLRs": http://www.bhphotovideo.com/c/product/833526-REG/Sigma__70_200mm_f_2_8_EX_DG.html/
Also, I wonder, if there is indeed and optical stabilizer in the Pentax version. I suspect B&H just copypasted the description from that for other cameras (CaNikon). Well, and the description tells that "Note: This lens is optimized for full-frame Nikon DSLRs and may also be used with smaller APS-c size sensors but it will increase focal length to about 100-300mm with most cameras." If it is optimized for Nikons, it won't perform well on Pentax. Right? ;-) Igor -- 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.
