Extension Tubes

After searching high and low, I couldn’t find a digital manual for my new-to-me Hasseblad extension tubes. I was fortunate enough to get a printed version with the tubes, so I’m pleased to offer one to the Hasselblad community, along with some insights about the tubes that were not really clear in the beginning.

Let’s say that 45 days ago you asked me the question, “What’s an extension tube, and what’s it used for?” I would have been forced to reply, “I have absolutely no idea.” Truth; but no longer. Let’s just say I know the answers to those questions — and I’m now an enthusiastic convert to something I wish I’d known about years ago.
