http://www.pbase.com/cameras/sigma/600_8_mirror Anyone uses Sigma 600mm mirror lense? SR should help with shake. Judging from other birding photos I saw bokeh isnt so nice, but somehow reminds me DA 16-45mm bokeh, yeah this DA lense too has this weird donut type out-of focus highlights...
Your experiences with 600mm sigma are greatly appreciated. Roman. -- 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.
