I have always had a thing for folding cameras. They sure look impressive to me! But many of them are low-end cameras with limited capabilities. I wanted a usable, versatile shooter, so I went looking for a folder with a fast and well-regarded lens. I found it in the Kodak Monitor Six-20.
The Monitor is near the pinnacle of Kodak folding cameras, second only to the rare and expensive (even now) Kodak Super Six-20. Produced from 1939 to 1948, versions of the Monitor were made for 616 and 620 film. Regular 620 Monitors came with an f/4.5 Kodak Anastigmat lens at 103 or 105 mm and a Kodamatic or Flash Kodamatic shutter that operated from 1/10 to 1/200 sec.
For more money, however, you could get a 101 mm f/4.5 Anastigmat Special lens, which is a four-element Tessar design. It was coupled to a Supermatic or Flash Supermatic shutter that operated from 1 to 1/400 sec. My Monitor is one of these. The CAMEROSITY code in the lens’s serial number tells me mine’s from 1946. I gather that Kodak started coating, or Lumenizing in their lingo, this camera’s lens that year, which made them perform better. My Monitor’s lens is marked with a circled L, meaning it’s Lumenized.
Monitors also came with double-exposure prevention and automatic film spacing so you couldn’t wind beyond the next frame, both mighty nice features in those days.
All of these goodies cost, of course. The Kodak Monitor Six-20 with the Anastigmat Special lens was $66, which is equivalent to about $1,000 today.

The Monitor comes with two viewfinders. The first is a brilliant type, attached to the lens assembly. It’s small and reverses the image left to right, making it challenging to use. The other finder flips up on the top plate. It is big and bright, and includes manual parallax compensation.

To use the Monitor, first cock the shutter with the little lever next to the brilliant viewfinder. Guess the distance to the subject and turn the lens barrel to that number of feet. Then frame the shot and press the shutter button on the top plate.
If you like folding cameras, I’ve reviewed several others, including the Voigtländer Bessa (here), the Kodak Tourist (here), the Certo Super Sport Dolly (here), the Ansco B2 Speedex (here), the Kodak Junior Six-16 Series II (here), and the giant No. 3A Autographic Kodak (here).

For my first outing with the Monitor I loaded Kodak Ektachrome E100G slide film. I paid through the nose for this film as I bought it pre-respooled onto 620 spools. In retrospect, I should have started with inexpensive black-and-white film, as I had trouble learning this camera’s ways and buggered most of the first roll. “Why won’t this thing fire? …oh.”

So I shrugged, loaded more expensive E100G, and kept going. When I worked the Monitor properly, it delivered excellent sharpness and color.

The Monitor has a clever winding system that stops when you reach the next frame. A lever on the top plate has two settings: WIND and 1-8. After you load the film, slide the lever to WIND and, using the red window on the camera back, wind to the first frame. Then move the lever to 1-8. For the rest of the roll, the winder knob stops when you’ve wound to the next frame.

On my first roll, this system didn’t work quite right and I ended up with overlapping frames. If the same happens to you, just leave WIND/1-8 lever on WIND. Then you can wind freely just like on any other folding or box camera. You just use the red window on the back to see when you’ve wound to the next frame. You do need one extra step here, though: to override the Monitor’s double-exposure protection. Just move the lever underneath the pop-up viewfinder to unlock the shutter.

My Monitor has another common Monitor problem: pressing the shutter button doesn’t actually fire the shutter. The real shutter release is on the lens housing. A complex linkage between button and release is prone to misalignment. The best solution is to screw a cable release into the socket on the lens housing. What I did was just stick my finger behind the lens and trip the shutter manually. Then I pressed the shutter button to release the winding mechanism so I could wind to the next frame.

On this second roll of E100G, I shot the Monitor on a tripod. I was quite a sight toting my kit through the Broad Ripple neighborhood for these photographs! The Monitor had to come off the tripod for this photo, which because of its lovely color is my favorite of all the E100G shots I made.

I came upon some expired Kodak Gold 200, probably among the last Kodak made in 620 before discontinuing the format. It came along on a trip to Bridgeton to see the covered bridge. Unfortunately, the processor goofed and developed this film in black-and-white chemistry. I like this shot best, which I cropped square because its native 2:3 ratio was less interesting.

I made one other successful photo here, but buggered up the whole rest of the roll thanks to shake caused by the way I was firing the shutter.

After I returned home, I finished the roll on familiar subjects. This photo tells a lot about the Anastigmat Special lens’s capabilities. The sharpness and definition are wonderful, but despite the Lumenized coating, the lens is still prone to a little ghosting.

I mounted the Monitor on a vintage tripod and displayed it in my home for several years. I think this camera is gorgeous and I loved looking at it. But it’s a shame to own cameras I don’t use. So I spooled some Ilford FP4 Plus onto a 620 spool and took the Monitor out to play.

Ilford film in a Kodak camera? Scandalous! But the combination worked well. By this time I was developing my own black-and-white film. I used LegacyPro L110, a Kodak HC-110 clone, in Dilution B (1+31). Ilford packaging said 8 minutes at 20° C, so that’s what I did. I scanned the negatives on my Canon CanoScan 9000F Mark II scanner.

All was not perfect with the Monitor after so many years. The shutter had gummed up a little bit, which I fixed temporarily with a drop of lighter fluid through the cocking-lever slot. Some shots, as above and below, showed signs of further shutter issues or maybe light leaks.

But when the Monitor hit, it hit big. Its lens is still a peach after all these years.

See all the photos that turned out at my Monitor Six-20 gallery.
I forget what I paid for my Monitor but it wasn’t more than $50. Today, you are hard pressed to find one with the Anastigmat Special lens for less than $100. You might save money buying the similar Kodak Vigilant Six-20, which could be had with this lens and shutter. It lacks the Monitor’s potentially troublesome winding system, but retains the Monitor’s definitely troublesome shutter linkage.
But the Kodak Monitor Six-20 is a beautiful folding camera, and is a peach to use when it works properly. You won’t be disappointed if you buy one. Mine is in the queue to be sent off for repair so it can shoot well for years to come.
