Which 35mm SLRs do not need a battery?

The Nikon EM has a 1/90 backup as well as the Nikon F3 but is at 1/60. The Contax RTS II has a 1/55~1/60 backup too.
 
i have to disagree. e.g the canon at-1 is full manual, but because of its electromagnet-controlled shutter only works with a battery. it has even not any manual emergency speed.

But that places it in a very exotic class of electronic cameras that disabled the (essentially free) automatic mode they inherently were capable of to fill a (felt) gap in the makers catalogue. I remember two more (one tiny, the other a big lump - Fujica and Praktica, perhaps?), but that may have been all there ever were - automatic SLRs without manual mode soon had replaced the mechanic, manual ones as the regular entry level model.

The Yashica FR series of camera are battery dependent, even in manual mode, if I recall correctly. So probably the Contax RTS also?

Now. I have to ask. Batteries for cameras of this nature are small. light, cheap, last almost forever. What is the problem with checking the battery condition frequently carrying 1-2 spares for emergencies? I always load a fresh battery for special occasions/trips. That has been my practice since forever (shortly after electricity was invented) and I have never ever had to replace a battery in the field.

Worry over cameras and batteries is DUMB!

That's my story and I'm sticking to it.

Picked up two cheap examples this spring,

Fujica ST605n
Sears KS-500 (Ricoh KR-5)

Both fully functional shutter speed range and aperture without battery.
 
Wayne,

There is absolutely nothing wrong and no problem with your suggestion. That said, meters themselves can die, and have done that to me. Or there is always the unexpected. It is nice to have the cushion to fall back on instead of the concrete.

Agreed. My current Pentax 6x7 had a spring break in the mirror return system on an outing in Galveston a couple years ago. I had the Hasselblad with me as back up. I rarely go anyplace with just one camera. In addition to spare batteries, I also carry a spare meter. when I am shooting with meterless cameras, I have two meters. One with and one without batteries.
Belt & braces, don't you know.

One of my favorite slr's the Yashica TL Super, the camera that started me down the photography road. I have not found one in years with a working meter.

It was my first SLR. It was 3 or 4 years before I figured out I might like more than a 50mm lens. And the Yashinon lenses are better than the reputation they usually get with a Yashi for part of their name.

And you are right about the light meters. I have never heard an explanation for that. It may just be simply a matter of corrosion on some of the electrical parts.
 
The Canon EF has voltage regulation...

The Canon EF (1 left in the closet) used the 1.35 volt batteries (mercury) BUT>>> it had voltage protection built into the circuit. Whatever battery you put in the camera, the internal circuitry regulates the voltage down to 1.35 volt. Why did not more camera mfrs do that????
 
I know that. I save my mercury cells for Bigfoot.
I am not convinced that the EF can compensate for alkaline cells when they drop below 1.35 volts. I need to find some silver oxide batteries which are closer to mercury cells.
Thanks for sharing.

Canon EF, it has a hybread shutter.....
Machanical from 1/1000 to I think 1/2s,(without batteries), no meter w/o batteries.
and it can electronicly go to 30s with batteries.

It also has an aperture priority mode also with stepless shutter speeds. (Battery needed),
About the same size weight of the Nikon F + prism.

From Wikipedia,

The EF used a unique shutter among Canon's 35mm SLRs: a Copal Square vertical-travel metal blade focal plane shutter. Unusually, long exposures (from 1 second to 30 seconds) were electronically controlled, while shorter ones (1/1000 second to 1/2 second) were mechanically controlled. This was very useful in conserving battery power, and allowed one to use the camera even with dead batteries
 
Hello Folks,
I saw another thread referring to people obsessing over batteries in cameras. I'm hoping this thread didn't begat that one (so to speak) as it wasn't my intention to announce an battery-related OCD on my side!

I started this one as I was just curious about cameras that don't 'need' batteries for setting shutter speed and aperture. I've been reading a book lately, the photographs in which were all taken using a Minolta STR-101. After looking that up (and reading that it only needed batteries for the meter and nothing else) it set me wondering how many other such cameras existed.

In general, I'm just fascinated with mechanical things: watches, cars: you name it. There seems an implicit elegance in solving a problem without a battery. I'm sure that others may disagree, but that's good too!

Best regards (powered or otherwise)
