So, I found this lens:

Then I found this adapter:

Would this be a good answer to my portrait length lens needs?? Its a little long, I think, but its fast. Suits my needs pretty well, so it seems.... I saw the name Zeiss and got excited, any good, this set up??

Then I found this:

Anyone know what sort of film, print size this uses/produces??
