At similar focal lengths and exposure settings could a digital camera be used as proofing/preview? Also, I'm pretty satisfied with the k1000's meter, is the 645's more basic or equal to it?
Think of the 645 as a Super Program - it is from the same era and pretty much has similar functionality, only translated to 120 film. While I don't have a Super Pgm, I do have a Pgm Plus, and have found its metering to be more predictable than anything Pentax have done since, certainly more predictable than the K100D's for example.
Perhaps the basic-ness has to do with the manual exposure indicator, i.e. can you meter down to 1/3 stop as indicated in the view finder. False accuracy I say, except perhaps in the studio using slide film
With the caveat about actual Pentax DSLR metering accuracy - and how well this translates to 'objective' light measurement, I don't see a reason why not to use one that way. Based on initial experience, adjust mentally to compensate for any difference.
