Settings equivalent to a Brownie Hawkeye

I’m just curious. What settings could you use on a DSLR that would be equivalent to those on a Brownie Hawkeye? I’ve read that the shutter speed is between 1/30 and 1/60 second but I’m not sure what the aperture, ISO, and focal length should be. Do 120 and 660 films denote what their ASA is? I’d like to experiment with some compositions given those parameters. Thanks for you help.

So...in conclusion...to duplicate the "look" your challenge will not be settings. Instead it will be in locating a suitably bad lens.

Those numbers need to be scaled according to format size.
An 80mm set to f16 will not be a Brownie mimic on a typical digital camera format.
As usual, achieving a desired aesthetic cannot be achieved merely by knowing a scattering of numerical facts.

My first camera was a Brownie Hawkeye and I still have it. There are no user adjustments on the camera. The 620 film that I learned may have been around ASA 100. The shutter speed is probably less than 1/60th. The fixed lens had great depth of field so I'm guessing that it was greater than f11. I don't remember ASA markings on the film I used but I was not interested in that at the time. I have seen more modern 620 film with ASA ratings on the package.

I had a Brownie Hawkeye as a child. As I recall it used 620 film which is no longer produced. 120 film is still available, and is the same size as 620 with a different spool. I've heard of people re-spooling 120 film onto 620 spools, but I suspect that locating the spools would be a hassle. I don't think I would do all that except for a more serious camera than the Hawkeye.
Well, as someone said above, Google is your friend. I just found that someone on Etsy is selling 3D printed spools and KEH has black and white film on 620 spools for $13.99.

Yes he needs to rescale from medium format to 35mm numbers. That is easily found in tables, and frankly he needs to do a bit of his own work on this so easily researched project.

There are lots of junk lenses on eBay. Another issue is finding an "affordable" medium format camera to hang the junk lens on. I've got a black Bronica S2a and assorted lenses, if anyone is interested. The Nikkor lenses Bronica used back in the day are hardly junk though.

The focal length is between "probably 75mm" according to http://kurtmunger.com/kodak_brownie_hawkeyeid149.html That's normal for a 2¼ inch square format. That's close to 45-50mm on a full frame camera.
The aperture is close to f/16 and it's focused at the hyperfocal distance which would be about 18½ meters.
A 50mm at f/16 would focus close to the same hyperfocal distance.
PS: I forgot to mention that the shutter speed is close to 1/30s according to that link. That means that the aperture and shutter would work in broad daylight for a film rated at about ISO 32. But with negative film you have more latitude and you could use higher speed film when there was less light.

That would be too easy. What he is trying to do is replicate the look of a medium format instamatic using his current dlsr.

Instamatic is a smaller square format, about half the size of square medium format and a quarter of the film area.

120 and 660 (620 is what the Hawkeye used) is the size of the film. 120 and 620 will give you a 2 1/4 inch x something negative. Kodacolor film was ASA 32 so your ISO should mimic that. The Hawkeye would have produced an in focus image from 6 ft to infinity. I have no idea what the 35mm equivalent of the Hawkeye would have been but i imagine somewhere in the 35-50 range.
I don't know what size sensor your DLSR has so can't calculate the hyperfocal distance but you will find a calculator at https://www.omnicalculator.com/other/hyperfocal-distance
As an example, the Kodak Pony 135 from the same era has a 44mm f3.5 lens and set at f11 and focused at about 14 ft would give you a in focus range of a little over 6 ft to infinity.

Exactly. But if you look at the hawkeye it is essentially an instamatic using medium format film. Only later did they reduce the size to fit what was regarded as miniature film.
