A900 at 6400 ISO

Go to last post
You are exactly correct :). And since my income is derived in high ISO and not so much in landscapes, then OK for landscapes is fine by me :). It's all about using the right tool for the job and for high resolution, mind blowing detail, the A900 is that tool!

taking the time to make the post instead of whining about it.

Better yet, go get your own and do all the "real life" testing you want.

Ah yes - the final solution!

Every so often I swear to myself that I'll never post samples/tests
again . . . but this one has had a good response, so I don't regret
it, and this poster was really only responsible for a little light
(and possibly deserved) sarcasm.

I think this post was of great value. It shows me that the A900 has noise characteristics similar to V4 of the A700 which quite good in my book.

Thanks for the efforts and the post.

Thank you! Pleased to be of service :-)

seriously, it's nice to have it appreciated - even if the aesthetic thumbs up is a bit of an impossibility!

I think pictures #2 and #3 have an interesting composition. Seems
reasonable if you're going to post a test picture, to at least not
make it a bad one. I've seen much worse then these. I would think a
good photographer couldn't help but have an eye for content, even if
taking a test shot.

Thank you! I must say, I was only photographing what was available, but i certainly did make an attempt!

great examples, so i guess if i buy a $3k camera & $1700 lens i
should be able to shoot iso 6400 of my bookshelves?

how bout some real life samples, i know alot of people here shoot
pics of their dogs and walls at high iso's, but i dont.

I don't either, but it should be easy for you to extrapolate what to
expect from normal shooting scenes with the supplied pics, and I
appreciate all of the effort that the OP has made posting these and
tons of other pics in other threads.

But in order to extrapolate we need of switching on the brain.
 
It has been some time since I last heard(or seen) of you. And it looks as if you're still keeping yourself up-to-date with technology. I have to confess I'm feeling a bit envious. Where is your M8? Hope not collecting dust in a corner. It would be a capital sin. I see you have a large printer in the corner of the pic #1. Would you mind telling me which one is it and how does the prints look?
Nice to se you
Keep posting every now and then.
 
From what I have seen so far in various places it seems that if you resize an A900 high ISO image to 12mp you can get fairly close to a Nikon D3/D700. I have yet to see a D3/D700 low ISO image resized to 24mp that looks as detailed and with as much resolution as an A900 image. Is that right?

Desaturated color with noise, I think ISO 6400 and 24 mp FF sensor are simply incompatible. We should decrease ISO or decrease pixel density. Since you cannot decrease the latter you have to decrease ISO. ISO 6400 is unusable and I guess it will be same in 5DII.

HI There
Someone in another place asked me to test this . . . so I have!

Here are some examples.
no noise reduction done (either in camera or not). I was careful not
to under-expose, and I've corrected the White balance on the CD
covers shot.









here's a crop of the last one:



All the above were taken in 'reasonable' light conditions - the last
one was in a nasty dark corner:





Well, it isn't as good as the D700!
However, it's worth remembering with the crops, that these are 100%,
and if you were looking at shots from the D3/D700 you would need to
be looking at 150% (or something like it).

I wouldn't be afraid to use it in lots of situations

I've printed them out to A4 size, and the noise isn't visible at all
(at least, not without a loupe, or 19 year old eyes!).

All shots taken with the Sony 50mm f1.4, as RAW files, converted to
DNG and then imported to aperture.

at ISO 200 converted in Aperture, if you have such images. I'm interested in the camera's RAW capability, because none of the JPEGs I've seen have been remotely impressive.

Thanks either way.

. . . dumped the Nikon gear?!

But, back to the thread. I am really glad that you started this one, because once the interaction got started, you've answered many of the questions which I had when I buzzed you with my earlier question.

As of now, and despite this camera's amazing production, it's still horses for courses. This is not a bad thing to recognize. And, for a great deal of what I enjoy photographing it makes the decision in favor acquiring the A900 easier.

Thanks much for your photographs and for your efforts in explanation.

Shalom!

Well, actually you sorta can. You can resize the A900 image to 12mp like some have done. They report the results are much better.

Hi Andre

The M8 is fine (it is resting a little at the moment, but just for a while :-).

The printer is an old Epson 4000 - still produces good output, but every so often it says it's dead . . . and I panic!
thanks for posting

Yes - probably (I haven't done the testing, but others have) . . . . but I still think that you can do much more Post Processing with the nikon 6400 ISO files

Hi John

Actually, although I don't deny the noise, the colour is pretty accurate (I have a desaturated environment :-).

These shots are not unusable - I've printed the 3rd shot to A3+ size, and it only requires a little noise reduction to make an excellent print.

Mind you - why you would get a 24mp camera to shoot high ISO is another matter (it's certainly not why I got it).

all the best

The results look very good to me.

If Nikon ever get the D3x out of the door it will hopefully have similar noise characteristics.

Then again, the 12 MP D700 is plenty for me, but for those who want more it is good to know it can be had without too big compromises in noise performance.
