Grated, that's why I said at least, yields may be able to be improved (as they have been significantly of late though new wafer cleaning and handling techniques). > Anyway, the cost should be dropping due to advances in chip > production, but again I do not understand why stop at 24x36mm while 48x36mm is > not really that much more expensive (as we already entered multi-thousand $ > price region).

Garbage, I see MF digital as a non-starter for me and a very high percentage of the users here. Apart from the likely price differential over a FF 35mm body the lenses are larger, slower, lower resolution (generally as I have owned and tested quite a few Pentax 645 lenses). I do however have a large collection of FF capable lenses which may or may not vignette significantly. > Someone who does not use wide lenses might not care, but given that Pentax > offer > is especially strong at the wide end, it should matter for Pentax customers. > In > other words, would you buy 24x36mm DLSR from Pentax, if pictures it takes with > your lovely 31/1.8 or 24/2 or 35/2 or 20-35 would look good only in the centre > of frame?

I'm afraid that your argument is purely speculative, there is no proof as yet that any Pentax 35mm lenses perform poorly on FF sensors. -- Rob Studdert HURSTVILLE AUSTRALIA Tel +61-2-9554-4110 UTC(GMT) +10 Hours [EMAIL PROTECTED] http://home.swiftdsl.com.au/~distudio//publications/ Pentax user since 1986, PDMLer since 1998 -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
