I hope it goes well, it will certainly be a learning experience and a completely new type of photography.
I started off by using 3 x Rolliflexes, a standard, wide-angle and tele model, with a Rollicord as a backup, this was in the early 60's - I wasn't rich but I was an employed trainee photographer at the time, so they were owned by the firm.
Later on, I bought a Mamiya C330 (from memory) with various lenses, that was a superb TLR, I then moved to a SLR, a Hassleblad, but it jammed up from time to time so I replaced it with a RZ67, which did everything that the Hassie did, but better and more reliability. I used it mainly for fashion photography, I had 2 spare backs and an assistant whose job it was to re-load them as I shot.
The Yashicamat was a capable camera, but very much a poor relation, don't expect too much from it. It was however streets ahead of the Chinese Seagull, I once knew the man who ran the Seagull factory, and we had a very good conversation, through a translator, an interesting man - but I couldn't share his enthusiasm for the cameras he made
