K-5 low light/High ISO samples

I'm hoping to document a medical mission next year and think that the K-5 will be the right tool for the operating room and other parts of the hospital. I'm looking for low-light samples from people that have gotten their cameras. BTW, I'm jealous!

FWIW, I'm looking for high ISO samples on Flickr and posting them to the Pentax K-5 dSLR Fan Club. Check it out - Flickr: Discussing Low-light/high ISO Samples in Pentax K-5 dSLR Fan Club

Thanks in advance!

While not totally low light- just crappy light- in an arena - here's one with no PP, and no in camera noise reduction at 10000 ISO. Definitely workable IMO I am loving my K5!

A bit of an overkill setting,

ISO12800 1/800 f2.8 (FA135/2.8)


In retrospect, I could have stopped down to f5.6 for much better DOF and still have an adequate 1/200 shutter speed.

Just posted this is the "post a photo" section, but I suppose it's more appropriate here.

Here's a very low light shot (ISO51200, 1/8s, f/2.8). It was still a bit under-exposed at those settings (to give you an idea of the lighting), but I was already maxed out on the ISO and aperture, and I didn't think I could hand-hold much less than 1/8s... plus my son probably wouldn't have held still much longer than 1/8 of a second

Just saw a few samples on a french forum, at 3200 iso in this post: Pentax K-5 : le même, en mieux - Appareils Photo et Caméscopes - FORUM Le Grand Forum
And higher iso further down, with links to the full size images on Flickr.
Not *very* low light but still impressive.

hmmm...I dunno but it appears that the K-7 has more detail or this might be caused by different focus or f-stops used. it could be that the K-5's NR is much aggressive perhaps? although I must say that the images look clean as compared to the K7.

Yes the focus is definitely different. On the front of the figurine for the K-5, and on the wings behind for the K-7. The poster explained the point was to show the noise handling, so he didn't care to reshoot the pictures.

thanks, I'm just worried about the detail rendering though.

I think he was so excited he didn't focus carefully Most of the shots are front focused, except the 12800 iso shot which seems a bit better in that regard. And he didn't write about the settings, the noise reduction may be strong.

If I had to guess, I'd say he just looked up at a street light or post light (you can see some kind of light source in his pupil). If he had been looking away or had his eyes closed right before the shot, his pupils would have likely contracted as soon as he looked at something brighter. Even if "brighter" wasn't really that bright on an absolute scale, relative to the moment before he looked it was, and therefore his pupils contracted.
