I see there are some photographers out there who want to enter the Medium Format world. Maybe my experience will help.
I have medium format cameras my Zeiss Ikon Super Ikonta (an oldie), a Yashica and my Mamiya. The Mamiya has three interchangeable lenses...I've also used a Pentax 6 X 7...but just with one lens the 90 mm leaf shutter.
They are all great, all use 120/220 film and are all relatively big, awkward and heavy (except the Yashica TLR) compared to a typical DSLR or a 35mm SLR camera.
Most of the time I used/use a tripod...a heavy duty one at that...a Leitz Tiltall...after I broke a lighter duty tripod when I was using the Pentax 6 X 7 .
I find the medium formats are more the studio or portrait/ landscape type of cameras. I spend a lot of time with composition when using them...for example I don't use a Medium format while taking a picture of a fast moving bird...I use my K10D and 55-300 mm zoom for that...I can move that combo faster than say my Mamiya with it's 180 lens...quite a heavy combo.
Medium format is an interesting area of photography, but if you haven't used one before I suggest you rent one or borrow one..try it out...see if you like it..it is quite different than a DSLR.
Also it's an expensive area of photography...if you think digital SLR's are pricey..medium formats, especially the digital variety can be very expensive.
You may like medium Format..or maybe not...but as I suggested before, save yourself a bundle and rent one for awhile and click, click, click...see if you want to really have a medium format. You may have a different opinion after the 'new' wears off, if you get my drift.
Personally I find my K10D to be a great camera...does what I want and with the right natural lighting for wildlife...find it hard to beat.
Just one old guy's opinion, based on long experience.
