Kodak Signet 40

I don’t need any more Kodaks. It’s not that I don’t like Kodaks, but I already have plenty in my collection. So not long ago I made a pact with myself – no more Kodaks! And then almost immediately I came upon this lonely Kodak Signet 40 for ten bucks. Clearly, my self-pacts aren’t very effective.

It was dirty, so I cleaned it up – but unfortunately with a little too much enthusiasm. See the outer ring surrounding the lens barrel? It contained a depth-of-field scale. Notice how I used the past tense there? My cleaning scrubbed it right off. Argh!

At any rate, on the Kodak scale the Signet 40 is a decent camera. It doesn’t rise to the level of the Retina line in build quality, but it is well assembled of plastic and aluminum.

The Signet 40’s 46mm f/3.5 Ektanon lens also doesn’t compare to the Schneider-Kreuznach lenses typical of Retinas. As best as I can piece together the Signet 40’s lens is a three-element design. The circled L on the lens surround announces that the lens is “Lumenized,” which I gather is Kodak-speak for a magnesium fluoride coating. This lens is also radioactive, as its glass contains thorium oxide. Curiously, this is a unit-focusing lens – the entire lens moves in and out as you focus, rather than just the lens’s front element.

The Signet 40’s Kodak Synchro 400 shutter allows shutter speeds from 1/5 to 1/400 second – pretty speedy for a camera of this caliber. You have to manually cock the shutter, though.

Up top is a frame counter, a film-type reminder wheel, and a very large rewind knob that gives tips for shooting with Kodak films available at the time. The wind lever is on the back in the upper right. The shutter button is on the front, right of the lens barrel as you hold the camera.

The Signet 40 was produced from 1956 to 1959. At $65 when new, which is equivalent to well above $500 today, the Signet 40 was a major purchase. But its features and reasonable build quality suggest that it would be a capable performer in the hands of a motivated amateur.

My Signet 40’s shutter was sticky, but I just kept cocking and firing it and pretty soon it loosened up. So I dropped in a roll of Kodak Gold 200 and started shooting. This camera was reasonably pleasant to use. The controls all worked smoothly. I especially liked the focusing ring, which operated with a single finger as I lined up the viewfinder and rangefinder images. My son was climbing the tree in the front yard with some neighborhood boys.

I have two complaints about my Signet 40. First, the rangefinder’s image was on the dim side, which sometimes made it hard to use. Second, the cocking lever was right next to the aperture lever at about f/16. I shot this roll Sunny 16 and more than once moved the aperture selector to f/22 when I meant to cock the shutter.

I met a friend for breakfast one morning so I brought the Signet 40 along. This ’64 or ’65 Plymouth Barracuda was in the restaurant’s parking lot. Modern tires always look strange on a vintage car.

Ooooooo Barracuda

Nearby stands the Astronaut David Wolf bridge, the last steel-truss bridge in Indianapolis. See a video of me driving over it here. The Signet 40 was an easy companion this day, light to carry and easy enough to use.

The Signet 40’s lens is reasonably sharp, with no softness in the corners. I wasn’t thrilled with the contrast I got, and so I boosted it in Photoshop. But that could be a processor fault rather than a characteristic of the lens.


I got delightful color on this roll.


The Signet 40’s viewfinder doesn’t capture everything the lens sees, making it challenging to precisely frame subjects. I found that the lens captured a little more on the right side of the frame than appears in the viewfinder. It showed up bigtime on this photo of this old Jeep’s grille, but I cropped the image to fix it.

The Signet 40 may look like just another cheap Kodak, but it’s a capable performer. If after reading this anything about the Signet 40 appeals to you, consider picking one up — you can buy them for a song on eBay.

  1. Was this one of Kodak’s higher end cameras? Did all of Kodak’s cameras use thorium oxide? Would that account for the great picture quality?

    What a cute find. At least it works despite your enthusiastic cleaning. It’s still a great little camera.

    Of course, I can’t end without commenting on the Barracuda. SWEEEET! True, you don’t see many Renagades either.

    • It was a pretty expensive Kodak for its day. Kodak’s mission was photography for the masses, so they sold a lot of inexpensive fixed-focus cameras. The thorium oxide was present in only a few of Kodak’s lens types, and was not used at all in their inexpensive cameras.

      The Barracuda was a remarkable find, especially out here in rust country. Those modern tires look kind of funny on the car, as if it were wearing shoes two sizes too big!

      • I have A-LOT of those fixed-focus Kodaks! Now I have something ELSE to check into at garage sales! Thanks! No, really, thank you!!

        Were those Craigers on that car? It does look a bit funny with those wheels.

        • They do look kind of like Cragers, but I don’t know for sure. I like my old cars restored to original, so when I see mods I kind of gloss over them.

    I like that shot with INDIANA poking through the grass. :) Any idea how they keep that clear? That’s the kind of thing I’d expect to be overgrown and lost in the soil in just a few years…

    • LP, it’s in a landscaped area — kind of a flower bed that gets mulched annually. So it appears to get enough maintenance to keep it from disappearing. There are two other pieces of this, I think they say “National” and “Bank,” as they were on the former Indiana National Bank building.

    • Thanks Cindy! It was fun shooting with this camera. I had more fun with my Zeiss-Ikon Contessa LK recently, and as soon as I get the film developed I’ll share about that camera, too!

    I just found my grandpa’s old Kodak signet 40. I am excited to use it. The range finder is way to dirty to even see through it. Any suggestions for a beginner to try and clean it?

    • Hi Kali — unfortunately, I haven’t tried taking my Signet 40 apart. I hear that Kodak published a service manual for this camera and that they sometimes pop up on eBay; perhaps you could look for one.

  4. Andre says:

    Thanks for your review! I have the same camera. I usually don’t buy Kodaks, but could not resist with this Signet 40. It looks very cool.

  5. I got a used Signet 40 from my grandfather in 1980…in those days flash units and other accessories were easy to come by at flea markets, and you could still get 5B flash bulbs at Kmart. I took a lot of great shots with that camera.

  6. Jaideep Sidhu says:


    Thanks for the review.

    I too recently purchased this camera and it is not very clean. I was wondering how did you clean the metallic exterior? Also, the viewfinder is dusty and dim, any recommendations?

  7. Ashley says:

    Hi! Great blog- I just bought the signet 40 at a garage sale. Picked up some 35mm film and was ready to shoot. However, I can’t see thru the viewfinder… It’s just black. I have the lens open. Any advice!? Thank you!!

    • Ashley, the viewfinder isn’t coupled to the lens. If you can’t see through the viewfinder, the viewfinder is simply broken, I’m afraid. I’m struggling to imagine just what could be wrong. Maybe something inside wiggled loose and is blocking the view.

    I bought my Kodak Signet 40 in 1956 for a wholesale price of about $40 (my father worked for a distributor of Kodak cameras). I used the camera exclusively for over 20 years and got many of my best pictures from it. The camera has been sitting in my closet since then, together with it’s flash attachment and the large and small flash bowls. I even have some of the bulbs left over. I think my light meter has long since disappeared. I am thinking of getting the camera back out of the closet and using it with some rolls of film, just for fun. I think the camera is still in virtually mint condition–no fading of the depth of field scale or anything else. But when I get it out again, maybe I will see deterioration from storage. I’ve since used everything from compact cameras to lots of SLR’s and DSLR’s, with lots of lenses. Somewhere along the way, I got lazy and mostly started using automatic exposure settings and taking lots of shots hoping to get a few good ones. I think my photographer skills were better with the Signet 40 and its predecessors that I used going back into the 1940’s. To this day, I am most comfortable with its 46mm focal length–a rare length in today’s market, and I really notice the difference when I use either a 35mm or a 50mm. I could get to about 46mm with a zoom, but like many people, I tend to zoom either all the way in or all the way out, and maybe back off just a little. So your blog on the Signet 40 brings back memories . . .

    • I encourage you to dig out your Signet 40 and shoot with it again. I’ll bet you’ll be surprised — both by the nostalgia of using it again, but also by how you view it now after so many years using SLRs and DSLRs.

    Hey there,

    I was jut wondering what you would consider a reasonable price for a Signet 40. The place down the street from me, dealing mainly in estate auctions, wants $40. Does that sound steep?

    • Sounds high. I’d want it for under $20. The best way to find out what an old camera is worth is to go to eBay and search for it, and then check the box for “closed listings.” It will show you recent auctions for that item plus the prices they sold for.

    This was a fairly expensive camera in its day. I wish my family had used such a good camera to take all are family photos on. Most of the family pics are on a cheap “camera for the masses” and are never clear or clean. I have several of the Signet model cameras. I have yet to find a Signet 80 I can afford. I have several dozen cameras in my collection, including three Retinas, but this model is my favorite. I once took a great photo of my Dad that was just perfect with color and focus. Nothing about the photo said antique. I enjoy your blog. It seems I visit many of the same areas as you. I am a Hoosier too.

    • What I find to be interesting is how many people bought DSLRs before the camera phone took over. It seems disproportionately high compared to the proportion of people who bought similarly expensive cameras 50-60 years ago. It seems like more people settled for the simplest snapshot cameras then.

      The Signet 40 really does do a nice job — if you can figure out exposure. Not everyone can, which might be why the snapshot cameras ruled then. Today’s DSLRs are auto-everything, which delivers great quality with very little thinking needed.

  11. Kimberly says:

    I have a Signet 40 also; but mine came with a flash attachment and I can’t figure out what kind of bulb to replace this one with. You wouldn’t happen to know would you? I am very new in the vintage camera seen and could use the help.

  12. It’s hard telling without seeing the flash unit, but flashes of this era commonly took #5 bulbs. I find such flash units to be more hassle than they’re worth. The Signet 40 is a wonderful outdoors camera!

    I acquired a Signet 40 but the rangefinder is pretty dirty. How can you clean the inside of the rangefinder glass (the one with the triangle)? Thanks.
