D800 - ISO 50!!! That's actually really welcome! and moire example

Go to last post
Always amazed how people can generalize.

just because you prefer 25600 or 25 does not mean most shooters or everybody?...??

Now, talking about ISO 50, here's why that is neat:

Worthless for most photographers, but I'm sure there are those who can get use out of such a setting on the small sensor dslr.

I concur. You'd be correct in many cases, but as another poster mentions- I prefer to reach for a ND filter.

  1. 2 Lower ISO meets longer shutter times which I can use with my flash! Also a plus.

I'd definitely rather use the ND filter unless I just didn't have one on me or not enough time to don one.

I'd rather have the 25,600 although I think most color photography past 6400 iso rapidly turns to crum even with the D3s (and D4 from samples that I've seen). 6400 seems to still be the realistic limit that I'd take a high iso performance camera and know that under certain conditions I can still get a decent color shot that won't be converted to BW later. 3200 iso is my limit with the 5d2 unless I'm converting the file to black/white (greyscale) later.

Truth be told, I'd much rather have 25,600 iso available to me if I saw Mitch Rumney coming out of a scary $60 hotel room with Lindsee Low-hand at 3am... wouldn't you? ;)

As been already mentioned. You can't use flash everywhere. You can't take a tripod everywhere (try that shooting an event). Bottom line is that High ISO is a far bigger concern amongst most photographers when compared to getting use out of 25 iso.

Low iso is very useful the D800 already has a lower base iso than the D3s and D700, at 100iso instead of 200, there is nothing wrong with wanting lower iso settings, they can be as useful as high iso settings to different photographers depending on experience. this allows you to use your lenses wide open with slow shutter speeds to allow minimum depth of field whilst blurring motion, or blur water whilst using reasonable aperture's.

Someone will come along and say you only need to use ND filters at the base iso of 100 but if you had iso 25 you can still use ND filters. To tell someone to use ND filters when they want lower iso is equivalent to saying to them use flash instead of high iso. they are just the two extremes of the same tool, I want both high iso and low iso, and cannot understand the animosity to those whose experience requires low iso settings.

And therefore we know that:

ND filters will:
  • reduce viewfinder brightness
  • reduce the amount of light reaching the AF sensors
It's okay with like 1 stop filtering. More and the above quickly becomes a problem, depending of course on the situation and the amount of extra filtering. Landscape photography? Usually not a problem at all. Weddings? I don't think so.

A true ISO 50 can definitely be a very valuable feature which is not satisfactorily replaced by an ND filter.

Exactly, if I wanted to shoot at 1.4 in bright day light i'd take my chance, expose at 100 and pull back in post. The histogram will give a rough guide how over you are.

I'll take the lower ISO.

The fee for that will be one stop of dynamic range, payable immediately.

Or just overexpose by one stop at ISO100 yourself.

Definitely true. Unfortunately, the D800 doesn't have a true ISO 50.

I think the harsh comments come from the fact that the OP doesn't seem to fully appreciate that the ISO 50 setting is not a true ISO. No one is faulting him for wanting to be able to shoot at low ISO.

When it was suggested that ND filters would be a better solution he responded that he didn't want to lower the IQ of his images by placing a filter in front. But somehow clipping highlights and lower DR by using the fake ISO 50 is ok?

From what i've read it's not fake as in the D700. (so no deliberate overexposure)

Nikon only states that ISO 100 is the best in IQ, that is why they chose ISO 100 as base ISO.

So I guess ISO 200 will be just as good as ISO 50.

Next you'll be asking me where i've read that.. and I don't know.

But I did read it for sure, it made me happy because I shoot long exposures a lot.
(therefore I registered in my brainternal harddrive)

cheers,
Mark

Shoot in UniWB and the histogram will be closer to the NEF. The histogram is generated from a JPEG and you can blow a channel without realizing it.

The amount of talk about ND filters here would seem to indicate you are underestimating the number of people who would use 25 ISO.

Thanks for the information. If it is as you think you read somewhere it would be an improvement over the previous models.

I don't routinely shoot outdoors with flash (where I would want a good low ISO) any more than I shoot at high ISO (which I don't do much either). But always good to know what is reasonable to expect in terms of quality.

There was a reason Velvia was so popular,.. yes and its color too :-)

I don't think it is worthless at all. If it was included, you and a lot of others would use it... a lot.

Instead of using a less sensitive, cleaner, better color preserving ISO setting... you would rather take the time to screw on a filter, putting yet another piece of glass in front of your lens... not only reducing colors, but possibly degrading the image in other ways.

Brilliant.
