Look at the first left bud
Are these crops or down-sampled? They all look fine on my end.

Might as well call me a troll too because my K5 and K5-IIs both kill my K1 regarding noise.
I can almost agree with you on that....I think my K5IIs was at least equal to the K, maybe not better but at least as good. The difference for me is low light focusing...the K1 shines in that area..the K5IIs, well, not so good. I have some great high ISO shots with both cameras....noise is not as important to me as it may be for some, but fast and sure focus even in low light is very important. The K1 pleases me superbly!

two accusations trolling and then a postulation the OP could be on drugs.. some of you are too much with the personal attacks.. and that is what you start with... first response to the OP. incredible.
Agree...we are better than that and should act accordingly. The OP does not fit the mold of a troller, and we should do some "troller research" before we start with the labels.

K1- Shot in very low light ISO 12800 1/80 handheld (Great SR!) f 7.1 @ 240mm...Bigma 50-500


My own experience tells me the noise depends on many factors, not just a few. Some are fine, others not. It was the same with my K5IIs.

If the OP needs help,some of you with better knowledge concentrate on helping him, not cutting him down...please!

Regards!

I always start at f/5.6. It's an old high school habit, but it works for me. I start at ISO 200 or 400.

I can hand hold down to 1/30 without creating motion blur. If the camera wants a shutter speed below 1/30, on K-1 I can raise ISO using the third wheel until I'm comfortable. With K-01 (same sensor as K-5) I have to shoot in TAv or take my eye out of shooting position to raise ISO.

Frequently in these shots, if I refuse to open the aperture, I will have underexposed, which I'd rather do than clip highlights. I sometimes go ahead, knowing I can adjust curves in post. I use PDCU to process RAWs sometimes, or PSE, and processing RAW's I rarely have noise when I raise shadows - but if I try to do a quick and dirty cleanup of a camera jpeg it is an entirely different story - they just aren't as malleable as DNG's.

My K-1 files are significantly more flexible than my K-01 files though. I suggest it much more likely the OP has some sort of settings or workflow issue than a faulty sensor, but whatever the case unless 1/200 f/8 is a full manual setting there shouldn't be appreciable noise.

Nice shot!
It's hard to make any detailed critique on a web size shot, but it looks sharp enough and noise is not intrusive.
A uniform background like that will tend to accentuate any noise anyway.
Do you have the option of adding some extraneous light and shooting at bas ISO?

Must have left the zero off the model number - K10d? Still, even that gets good shots at iso 800.
I shot with my K-10D for years and loved it. Photos from this camera are in stock galleries. Came out really well. My K3 is better still, although with Tamron 70-200 f/2.8 hunts a bit. My K-1 is wonderful.

A couple of high ISO images for you....

Both shot at 3200 ISO



IN this one I even have rescued shadow detail on the otters chest, still no noise.

You can say whatever you want about a K-5 being able to do this. My wife has a K-5 which she still uses every day. My advice, if you believe that, go out with the two cameras and shoot some side by side images using the same settings. Post those, and then we can decide if your K-1 needs servicing.

Just because you are shooting high ISO doesn't mean you can under-expose your image. What I see in your images is large parts of the image that are grossly under-exposed. IN High ISO work, that will lead to emphasized noise because of the amplification required to try and make it look normal. Shooting high ISO means you need more precise control of exposure. and because of the reduced dynamic range, you need to keep the left hand side of your histogram a little bit to the right of the chart border to create some shadow rescue room. It's exactly the same as if you tried to push 800 ISO film. You can do it, but the size of th grain will be enormous.

Gerard, your samples look fine to me. On my screen the noise is fine and not harsh.

To be fair to the K1 you should also downsize images to the resolution of the K5. Once you do that the K1 should be a very clear winner when doing high iso shots. People keep comparing at native resolution which is biased in favour of the K5.

Anyway, if people truly believe the K5 is better than the K1 at high iso, good on them. They can save a stack of cash.

I have been using my K-1 at work hand held for quick documentation of quick museum installation shots involving some action, so a low shutter speed is not an option, and most everything needs to be in focus, so smaller stops as well. Due to the lighting and the nature of some of the scenes/work, it's also low-light-ish. Mostly shooting iso 1600-6400, and underexposed there to boot but multiple stops. Basically a torture test. The K-1 has performed well, but there are no miracles. The shots are acceptable for the purpose, and spank any phone shots. My Z is far better recovery wise. And it does seem like some shots work better than others.

Occasionally I'll add a little light and that helps a bit ( and I need to continue to work on a quick and portable non-flash battery powered lighting option/s).
