Hi All,
When we were talking about the Hasselblad SWC, the Bessa Angle Finder was mentioned (Phil recommends it and based on his recommendation, I ordered one before I even bought the camera!) It finally arrived yesterday and Phil was right (of course), it offers a 
much clearer view.
In any event I recall others mentioning looking to get a Bessa and couldn't find one because they are no longer being made, and I had been searching on eBay and all the usual places myself. As it turned out, I found mine hiding in plain sight, on the B&H website. They still have them for sale - though there is a wait because they don't keep them in stock. They must have a source somewhere until they run out. In case you're looking, here's the link:

And FYI: No pictures from the SWC to show off yet. Between work and my writing (I've been busy blogging about Downton Abbey for PBS) and the 
freezing temps, it's been hard to get out to play with it. If it doesn't warm up this week I have an indoor space I might try to shoot (out of desperation!)
