What digital camera has the lowest ISO setting?

Question

What digital camera has the lowest ISO setting? I know there are digital cameras that go up to 1600 ISO or more, but what about the other extreme? Do any digital cameras go well below 100 ISO. I'd like to be able to take a time exposure (15 seconds?) in broad daylight with mechanically attaching a neutral density filter.

Answer 1

The old Nikon Coolpix 8700 & 8800 point & shoot models had 50 ISO. Neither one had a lens thread but they did have an optional adapter tube for a filter thread. (both models provide 8 megapixels and good image quality.)
If you're looking for a dSLR, the Canon 5D and 1D models have 50 ISO.
Compared to any ordinary 100 ISO camera, that provides one extra stop. The right ND grad filter can provide 8 or 9 stops by itself... And you can stack filters.... Alternatively, you could do a time lapse and merge those pictures. (say, 3 to 10 shots over a 15 second period.)

Answer 2

I don't know right off, so I just chose a few likely suspects.

Pentax Optio A30 - ISO 64
Nikon Coolpix P5000 - ISO 64

Nikon Coolpix S10 - ISO 50
Nikon Coolpix L12 - ISO 50 - but it looks like it uses "auto" only to determine setting

There must be others. If I was choosing quality, I'd look at the Nikon P5000 first. That actually looks like a pretty decent camera.

I don't see ANY dSLR's going below ISO 100 and I think I caught them all. (dpreview.com)

Answer 3

I don't know about any other cameras but my camera goes to ISO 80. It's the Sony Cybershot DSC-H2; and I try to keep it at 80 as much as possible.
