Seriously, I have a
 few 5*4" sheet film cameras. Perhaps that's why I don't think digital
 cameras have even marginally useable resolution. 
Tony, I have a 5*4" enlarger here that's, um, surplus to
requirements.  I used it a few years ago for 6*7cm enlargements,
but I don't have that camera any more.  Do you want the enlarger?
