A second test shot in the crappy lens category :-) The Sigma AF 75-300mm 4.5-5.6 gets reported as Pentax F70-210mm. Handheld, SR on at 115mm (175mm) at ISO 200 125/F4.5 slightly cropped here. I used auto settings in the converter and sharpened the photo after resizing it in Photoshop.
The Sigma get quite sharper at that focal range, I find it even usuable here for small prospect prints. I don't expect the same nice background rendering as with a Pentax prime here. http://www.mypage.bluewin.ch/solicom/sigma75300_flowers.jpg greetings Markus -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
