Thanks for all the help here, i so appreciate it, and i hope it didn't hijack this thread too much or we went off-topic.

In all cases, any gear without rechargeable battery option will have my bad feedback or cons always even if it delivers high quality results.

So going back to the topic, which 6x6 body or system you prefer or like? I have Hasselblad 501CM, only that focusing screen was the issue, i bought new one from ebay that is 45-deg split imag focusing screen, it is slightly better than my two Matte Acute-D F_screens, but still not that perfect, got a recommendation of a brand from a member i can't remember now but it is so expensive alternative, so i am not sure if that will be the key, or looking at another 6x6 format body?
