On the Rolleiflex front, I found a very clean example of a Rolleillex 3.5C. The camera was pristine but the shutter was frozen. A few months later, it was serviced by Optomeca and now it has became my goto camera. It was a pain to get some filters ! I regret that I didn't buy Heliopan filters when I had the opportunity.
My first "professional" medium format camera was a very early Super Ikonta B with an uncoated Tessar. I bought it at a camera show in Grand Rapids, MI. for $80.00 in the mid-70's. Later,I had to sell it to fund the purchase os a 50mm Distagon and 150mm Sonnar for my Hasselblad wedding outfit. The onein the picture was bought from a pawn shop in non-working order, but like new condition. I knew I could repair it so I bought it. It's coated Tessar is outstanding, but it can't beat the 100mm f3.5 Ektar on the Medalist II. Both cameras are extremely well built and function perfect.
First choice: Mamiya 7 with various lenses when size/weight/space aren’t an issue.
Second choice: Ercona II with Tessar when carrying the Mamiya 7 is inconvenient.
For skiing: Voigtlaender Perkeo II with Color Skopar because it’s tiny and light enough to fit in a small Conterra chest pack under my ski parka; I’ve learned that if the camera is in a backpack, I’ll never use it. A slip-on yellow filter in a minimum-size jewel case goes in a breast pocket.
I have others but these are my top three in terms of usage.
