The lowest ISO setting on your camera?

[Huss]

So I just found out (!) about Kodak 2254 with its ISO rating of 1.6.
1.6 means in blazing daylight you can shoot wide open AND have a low enough shutter speed for motion blur.
I was looking to see what gear I have that can meter at that level (w/o using a separate hand held meter) and found that my Leica M7 can be set to ISO 6, then 2 stops of exp compensation can be dialed in so it actually can be set to ISO 1.5!
My Nikon F6 can also be set to ISO 6, but its not with me at the moment so I'm not sure if I can set that too at 1.5. The thought of using Sigma Art lenses with that film is quite delicious!

I'm assuming there are other kameras out there that can be set to 1.5 (using exp compensation dial). What are they?

My N90S can meter at ASA 6 and it has plus or minus 5 stops of compensation.... I'm not even sure what that would be on the low end. Or even if it would be accurate. I recently shot some Adox CMS 20 film and the recommendations I read for metering and processing were ALL over the map!

But can you set it at +5 (or +2) at ISO 6? With some cameras when you hit either end of the ISO setting range you cannot dial in exp compensation to go beyond it.

Good question; I'll have to give it a try!

My Bronica SQ with SQ-i back goes down to ISO 25, with -2 stops exposure compensation on the back, plus an additional -2 stops on the SQ-i prism. However, for whatever reason, the exposure starts climbing back up when I set it to that. More experimentation necessary...

The Leica M5 meter goes down to ASA 6. No (dedicated) exposure compensation, but I guess you could achieve ASA 1.5 by underexposing two stops?

I would think so. That's probably true of a lot of cameras; best accuracy would be obtained if the needle readout in the viewfinder has a scale marked with stops (not all do).

Leica M6 lowest is ISO 6.

On my SL35E, 25 ISO. It has +/-2 Exposure compensation, so aroung ISO 6 as well.

Nikon F3P

Lowest setting is ISO 12
Compensation at ISO 12 is -2 to +1⅓
in "A" mode the shutter speed reflects the compensation setting

Highest setting is ISO 6400⅓
Compensation at ISO 6400⅓ is -1 to +2

Normal compensation is ±2

Funny thing I used to wonder why it went so low
with some cameras.

Hmmm so w comp u can set it to ISO 6

umm probably a bit lower, since 12 ISO - 2 Stops = 3 ISO? I'm I wrong?

Example exposure at f5.6

ISO 12 = 1/8 second
with +1 = 1/4 second (ISO 6 equivalent)
with -2 = 1/30 second (ISO 50 equivalent)

Correct me if I am wrong

Ok just checked my F6. Lowest ISO setting is 6, but I can then dial in +3EV! So it will automatically meter down to ISO 0.75.
