If you had only 1 (one) ISO setting available?

The base ISO - 200 in the case of the EP3.

 

Well, the measured dynamic range and color capabilities of our cameras only give the full performance at base ISO, so it's hard to choose something else. I was tempted to choose 400, as it's a decent compromise (increased sensitivity without too much additional noise, and it still retains a decent dynamic range and color space) but I think I'm going to have to say 100. Actually, why not 200, gives me a tiny bit of leeway for less static photography.

 

If I only had one ISO, I would be shooting a film camera. The film speed would be 400.

 

50.

ISO 800, better noisy photographs than blurry.

 

ISO 1600 here. Gotta have those shutter speeds up there. 3200 if the sensor could bear it, but on m4/3 they really can't. On APS-C or especially FF i would say 3200 though.

 

It depends on what kind of camera u have , I would choose 400 anyway

I would stay off the coffee and choose 400...

 

If I could have just one ISO setting...
...it would be Auto.  

 

i like to chooe 400 but i think i can live with 800 (in e-m5, hehehe).
like they said... it's better noisy than blurry.

 

When I shot 35mm film my most commonly used ISO rating was 400 because it was the best compromise so that's what I'd go with now.

 

400. Similiar to what Geoff said - I usually have ISO 400 film loaded in my SLR, maybe sometimes ISO 200 film in my rangefinder.

 

200

ISO 1600, due to all the low light stuff I shoot, with a ton of ND filters.

 

Base ISO for the sensor. I don't shoot rapidly moving objects and there is always IS, door frame, fencepost, monopod, tripod, or a string & washer to help stabilize the camera if needed.

 

Take the ND filters off and the low-light stuff becomes easier. :whyzas:
