The Pentax 67 is "the preferred walking around camera"??
Really?
The Pentax 67 is no 'walk in the park' if you think so. It's 3.4kg with the firecracker (and street-smart!) 75 2.8AL and TTL prism. Then add the lenses. What is the RB67's/Mammy's weigh-in? Have you walked 6km with one, and a pack of 5 lenses? It's not all about the camera's own weight, but the whole kit and caboodle.
Old MF cameras are invariably heavy or bulky. And given the quality of imaging (in skilled hands) and application, it is
the tool for the job for many people hellbent on quality (rather than just getting a snapshot).The RB67 looks significantly bulkier but not owning one (nor any wish to), that's for others to confirm or deny. There are a few RBs around in dealer windows that look quite boxy and awkward. Somebody on the Australian Film Photographer's Facebook page has picked up a Mammy ex-Japan.
Now, about this business of the 67 needing a tripod.
Personal technique -- what you are photographing and your preferred ballpark exposures (e.g. 1/8 vs 1/500 to 1/1000) play a role in whether you can get by without a tripod. Many people
do use the 67 exclusively tripod-mounted. It's not a case of "who to believe and who not to believe", but clarifying what your technique demands. Obviously a tripod is not going to be a good idea on a crowded street where it poses a hazard to others.
Some observations. I have critically examined others' images from the 67 printed to 6x4 (!) and they've whistled Dixie until the cows came home how
"really bloody sharp this pics are!". Oh? But are they? Unfortunately no. Evidence of vibration and movement is extensive when scrutinised, even if the negatives/transparencies look sharp on first glance. Images at 1/125 under loupé are emphatically not sharp handheld, certainly not thost at 1/8! I've compared these to my own where the 67 is tripod mounted. No problem at any speed. Yet amateurs persist in banging on about the 67 never needing a tripod,
"...sharp at 1/125...", "even 1/4 sec 'cause I'm steady...". If you want the very best imaging quality this camera can provide (and desire to print to fill a wall, rather than a Wallmart postcard), mount it and use the camera methodically to achieve the best it can deliver. OTOH, if you don't care for (or your reputation does not ride on) the finished image, use it handheld, however you please.
