The other day someone made a remark similar to "if you're going to invest in lenses, note that all electronic lenses will die". From this I began to think about which of my cameras I would keep if I wanted to have cameras that were the least reliant on electronics. I'm not saying that philosophy is reasonable - it's just a fun exercise. The only cameras I have that fit this requirement exactly are the Leica M3, Nikon F, the RB67, Hasselblad, and Fuji GW690III. However, since I often don't use a meter at all, I could include the Nikon F2 and the Speed Graphic (the only thing the battery is used for is the beam-focus).
It also made me wonder what the most recently manufactured totally mechanical camera is (other than large format)? I believe RB67 Pro SD's were available new until about ten years ago.
Then, this made me consider what the various Electronic Independence Levels (EIL) of cameras are. I thought of the following:
EIL 0 [no independence]
These cameras cannot function in any way without a battery. All digital cameras fall into this category. The more modern film cameras, such as the Canon EOS and Minolta Maxxum, fall into this category because film-wind, shutter speeds, and other operations are electronically controlled even though focus can be switched to manual. Nikons from the F4 onwards are here.
EIL 1 [little independence]
Although it is possible to use a camera in this category to make a photo without battery power, such use is severely restricted. With no battery power, the camera may have only one or a few fixed shutter speeds that can be used. Film could be advanced and rewound and apertures could be changed manually. One example of this is the Nikon F3.
EIL 2 [fair independence]
In this category, film-wind and shutter operation are manually done. Electronics are mostly for metering, but might with some cameras be used for aperture priority operation - however, manually set apertures are always possible. Lack of battery power is mostly just an inconvenience because the meter would not be used. Examples of this would be the Leica M6 or the Nikon FM3a and the F2 with metering heads. Note that even the F2 with the DE-1 non-metering prism still has a battery compartment in the body which gives testament to its electronic nature.
EIL 3 [good independence]
Cameras in this category have no battery at all but use something like selenium cells to control a meter needle. Typically, adjusting the shutter speed and aperture manually causes the needle to be centered or causes a second needle to match the first. Many cameras of the 1950's and 1960's fall into this category, such as the Voigtlander Bessamatic. In a camera of this type, are there any cameras where the needle is trapped and the trap position is used to set the aperture or shutter speed?
EIL 4 [total independence]
Cameras in this category where never designed to use any battery or electronics; they are fully functional without electricity. Many cameras from the 1950's and earlier fall into this category, as do most large format cameras and many medium format cameras. Examples here would be an Exakta VX, Leica M3, Hasselblad 500C, or the Nikon F. Yes, you can add electronic metering heads to the Nikon F, but the battery is in the head - the Nikon F of 1959 was designed as being totally mechanical.
Yes, I've ignored flash sync, but I never use flash - so it doesn't exist. Mostly I've done this exercise just for fun, seeing which cameras I have fit into which category.
