I picked up the Pickwik Reflex at a garage sale for $4. As I recall, the woman assumed a camera that old (circa 1940) would only be good for decoration; she was surprised when I told her it looked like it would actually work.
It’s a pseudo-TLR box camera that takes half-frame photos on 127 film (aka Brownie film). No settings other than Instant / Time (Bulb) for long exposures. Online reviewers of this camera generally mention that the half-frames tend to overlap, and that the focus is iffy. Given the heads-up, I was able to wind the film so that the “A” exposure was at the very leading edge and the “B” was at the very trailing edge, so I only got two instances of overlap: the very first four exposures, which were my test of winding the film “correctly” versus intentionally overcorrecting.
As far as the iffy focus, I’m convinced it’s a film plane issue. Each of my exposures were out of focus in one place or another, and they weren’t consistent — not like other toy cameras that have specific sweet spots.
I picked up the Brownie Bullseye at a garage sale at the Old West End Festival a couple of years back for $3 or $4, boxed, with the flash attachment. After letting it sit in its box on top of my camera display shelf for a year or two, I finally got around to running a test roll through it this past May.
I tried to start simple, by removing the lens on my Argus C3. Unfortunately, I was stymied by the very first step of unscrewing the idler gear cap, since the cap probably hadn’t been loosened in the past 50 years. Even a couple squirts of WD-40 didn’t help; after a half hour of futzing with it, I developed friction blisters on my finger and thumb and called it a night. I’d like to someday get the wide-angle lens for my C3, but until I can free up that idler gear cap, it’s a no-go.
I also like the quirkiness and unpredictability of box cameras and toy cameras, especially those with a zone focus. My
