Hmm,
Mechanical vs Electronic shutters ..
Are there any noticable differences in reliability between the RB67 vs RZ67?
Thanks,
Stephen

I have not used the RB or RZ systems, but I have used the Mamiya 645 system for more than 20 years and the electronic shutter in the 645 cameras always functioned flawlessly.
I actually prefer electronic shutters. They're more accurate, they rarely need adjustment, they're simpler with fewer moving parts and many of them are designed to never need lubrication. I have never, in 30 years of using electronic shutter cameras, ever had to have one CLAd.
Mechanical shutters need their lubricants periodically cleaned out and reapplied. They also need the speeds adjusted over time to keep them accurate. Most only offer timed speeds down to one second, while many electric shutters offer speeds out to 30 seconds.
The only advantage mechanical shutters have is that they do not need batteries, and that is really not an issue. Batteries are cheap, and in many cameras they last a long time. I changed the 6-volt SR44 battery in my Mamiya 645 about twice a year. Hardly a serious burden. I should note also that I used the 645 in Indiana's cold winters, sometimes standing in knee-deep snow in air so cold I could barely move my hands. The 645 NEVER had a battery die due to cold, nor did it have any other issues from the cold.
