I've found that the 2/3 stop between f/1.4 and f/1.7 can make a big difference, and that shooting indoors with my 8/3.5 I tend to get a lot of that "artsy subject motion blur". I'll be very interested in seeing how this lens works. If Samyang ever starts putting their optics in lenses with autofocus, Tamron and Sigma will be in serious trouble. Then again, if they start doing that, their lenses won't be nearly so inexpensive. -- Larry Colen l...@red4est.com http://red4est.com/lrc -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
