I have a Mamiya m645 1000s with the following lens:

80 2.8
80 f4 Macro
45 2.8
150 3.5
210 f4
300 5.6

These are all "C" Sekor lens

I also have a Metz 45 CT-1 Flash

If I wanted to update to a more modern Mamiya MF Model, which models would still accept my lens.

I am guessing all the 645 designated models will accept my lens, which I think encompasses the J, Super, Pro, Pro-TL, E....

Do I have it pretty right or are there others......and if so, are there any recommendations?

Thanks in advance for your time
