Looks interesting. I'll show it to my Digital Photography I class tomorrow (coincidentally, "Black & White" was the assignment for this week). It'll be interesting to see what they make of it and if there's any interest (I won't mention the price because that alone will kill any interest from students). My thoughts tend in two directions: The disadvantage is being unable to really control spectral response. Since they've actually done away with the RGB filters over the pixels you're stuck with the spectral response you're given (other than by using traditional colored B&W filters): There'll be no adjusting the response curve in post the way you can with RGB images. The advantages are, well first of all you *will* be able to use traditional colored B&W filters (the results when they're put over RGB sensors are weird). You'll also get higher sensitivity (no filters over the pixels) and lower noise (and no chroma noise at all!) Theoretically, you should also get finer detail, though with over 25 megapixels crammed into an APS-C area I'm not sure how evident that will be. I'll wait for real-life tests but I imagine you'll need the highest resolution lenses to see much difference. -- Mark Roberts - Photography & Multimedia www.robertstech.com -- %(real_name)s Pentax-Discuss Mail List To unsubscribe send an email to pdml-le...@pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
