Cheers, Paul. I am bathing in shame and remorse. It does not get any sillier than this!
Well, that means I will need the 645 Pro TL body. Yesterday, I bought a new 4.0 / 200 mm for $ 208. It was sold as "new" on eBay by a Columbus OH dealer on eBay. But I also so a "new" APO 2.8/200 mm for $ 749 overseas and a good one for $ 400. Phew, it's a relief that manual focus Mamiya glass is affordable. MF would complement even a Canon 1 Ds Mark III nicely. At least, I feel the urge to use different cameras for different jobs. In MF, one works more conscious, thinks twice before taking a photo while many DSLR users just fire away.
Thank you all for taking the time to help!
