Like many of us I have learned the "hard way" in many areas of life my examples:
Cheap limited view camera... only to pine immediately for a better one... lost money and time and very frustrated with that.
Married a great practical women that cooks and balances the checkbook... dumped the "hot fun" women... I won on that one.
Bought rusty MGB thinking I could fix the body cheap.... looser!
Bought rust Free Mazda RX7.... that turned out to need an engine.... lost again!
Built a sailboat on the "cheap"... took 10 years... should have put $450 a year in a jar and just bought a finished boat after 10 years.
Bought a Hasselblad and grew the system... haven't bought a new lens in 14 years... and plan to keep it along with my wife..... great winning decision. Glad I didn't buy the heavy RZ system that was 35% cheaper at the time... the Hasselblad travels everywhere and goes where a 35mm can go... and gives negatives that can rival 4x5.
My Hasselblad is the reason I gave up on 4x5 too. Time honored lessons learned are the best ones. I too don't mind traveling with my Hasselblad. Out of all my cameras, if I could keep just one, that would be the one.
What I personally like about it is that it doesn't require batteries.
The lenses are in a word amazing.
With the 80mm lens it's very portable as it is sleek, compact, and fairly light for its size.
I can shoot it hand held at 1/30s by using a strap around my neck and resting it against my chest as I use the waist level finder.
The ergonomics are superb, and hand held the camera just fits so nicely in my hands. Focus with the left hand as I hold the camera with the right hand, and operate the winding crank and shutter release with the right hand.
It makes my tripod more compact, because I never have to rotate the camera, which also puts the center of gravity lower, which makes the tripod more stable and firmly planted.
I'm not saying that other cameras can't be just as good for various reasons. I'm just telling you why I love the Hasselblad so much. I have never tried a Bronica setup, or a Mamiya 67, so these are just observations. I hope they help you along in your decision making process.
