Nons instax back works pretty well. Shot this double exposure. Used black tape over the lens to prevent exposure on opposite sides. Used a flashmate to meter incident in the shadows then went down 1 stop of light with the shutter so I didn’t blow it out. Finding that the instax film cannot handle over exposure. Pretty easy to double expose with the rb67. And easier with the instax back.

Continuing my testing. This one from the last product series comes with the Yashinon lens instead of the more common Yashikor. Just got my Yashica Mat 124g. The viewfinder is way brighter. Even brighter than any Rollie I have seen.

I’m genuinely curious why these cameras don’t get talked about more.

They aren’t as lightweight as a Mamiya 7, but they’re considerably lighter than a Pentax 67. Compared to the fixed-lens GW670/690, they offer interchangeable lenses and proper long-exposure capability.

On paper, they seem like a pretty compelling middle ground. What’s the catch? Are there significant drawbacks I’m overlooking?

Very impressed by this lens and super impressed this $400 beat up Pentax 6x7 works as well as it does.

First couple of test frames from a Yashica 635 for light leaks which I now own. I'll send it for CLA for some minor issues. Comes with a full set of 35mm adapter.

In this week's camera collecting blog, I discuss the 1955 Rocca Super Reflex, a rare Montanus twin-lens reflex, a poor man's Rolleiflex at $100 in 1956.

What drew me into this wonderful twin-lens reflex camera was the look. It's got a Steinheil Cassar 80mm f/2.8, a Prontor SVS shutter, and a FANTASTIC thumb-slide focus. Loading it nearly cost me a whole roll of film.

Please take a few minutes to familiarize yourself with this interesting camera.
