My experience (and therefore my opinion) are hardly influenced by anyone.
I purchased my first MF camera 25 years ago: a Mamiya C220 with a 65mm lens. That camera and lens are still in use today. And with proper care (in other words, with heavy use and an inexpensive CLA every 20 years), it should be good for 100 years. I don’t see why it would last less than a rolleiflex.
Over time I have added many rolleiflexes abd other uBer expensive gear to my arsenal, but I have also overbuilt my Mamiya TLR Kit, which I use regularly next to the rolleiflexes.
The only reason for having indulged into the rolleiflex was pure romanticism. And as a young adult, the hasselblad ownership was born out of a complex.
In hindsight, I could have lived with only a C220 all this time. And no, it’s not heavy, it’s at least like a Rollei 2.8F. And with the grip, it’s very comfortable. And the screen is very bright.
If I had to, I could travel the world with a Mamiya TLR without needing anything else, ever. I’d definitely not do that with a hasselblad, bronica, folders, RB or RZ.
This is only my opinion based on 25 years experience with a mamiya TLR while many other cameras couldn’t go beyond a few months.
