With the additional note that the 1Ds (mark I and II) can't be converted, because these have the filter (combined IR-block & anti- alias) sandwiched onto the sensor....seems to coincide with CCD versus CMOS. Perhaps someone familiar with both these chips, in design- and manufacture-context, can shed a light on this? (with the most important question being whether one could order a new 1Ds without the filter, straight from the factory (like can/could be done with some aftermarket digibacks for medium format; no IR-block, no anti-aliasing) -- Bye, Willem-Jan Markerink The desire to understand is sometimes far less intelligent than the inability to understand <[EMAIL PROTECTED]> [note: 'a-one' & 'en-el'!] * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
