The Astronaut David Wolf Bridge

The Astronaut David Wolf Bridge
Kodak Signet 40
Kodak Gold 200

This is the last truss bridge still standing in Indianapolis. It was built in 1941 to carry State Road 100 across the White River. Its two Parker through trusses are bookended by Warren pony trusses.

In 1941, this was way out in the country. The Indianapolis city limits were several miles to the south. But as the city expanded outward, as cities do, eventually this region became suburban, and this road became a major shopping destination. This road, and therefore this bridge, were no longer sufficient for the traffic volume.

Fortunately, sane heads prevailed. When the road was widened to four lanes in the late 1980s, a new two-lane bridge was built alongside this one to carry westbound traffic. This bridge was left in place to carry eastbound traffic. In 2008 it received a thorough restoration. Somewhere along the way, the city of Indianapolis named it after astronaut David Wolf, who was born and raised here.

This is a challenging bridge to photograph given its length and how many strip malls crowd the area. Once I made a through-the-windshield video when I crossed this bridge; you can see it here.

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.

Wall and window

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.
