k-7 looks beautiful at ISO 4000

Sure, there's some noise. Blah blah blah. Looks good to me. This is JPEG out of the camera, no modification (except the resize down, of course).

that would be the work of a night-vision camera or IR.
I was trying to make a joke
I was going for the abstract thing of "darkness".

But you would be correct.

very nice shots here taken with Pentax cameras, it doesn't matter if it's a K-7, k-x, K20D, K10, K200D.

Nice shot, Lance B--as impressive for being hand-held at that FL & shutter speed as for the iso.

no problem. just keeping those K-7 owners and potential would-be owners happy and don't feel agitated by all these complaints and scary stories about ISO numbers and where the the K-7 ranks.

just let you and the camera do the talking and forget about the numbers.


RAW is definitely better. right now, I'm just out of HardDisk space and memory card space. and my RAW converters are going nuts as of the moment. dunno why.

regarding the k-x, it is better at High ISO but I would rather wait for a full-frame with a much higher ISO range. a 12800 output with an equivalent of a 400 ISO would be just great.
I am very satisfied with the K-7 iso performance. If you check through the previous pages (a rhetorical statement) you would see me post many high iso shots, even iso 3200 pushed two stops for a 12800 shot which all came out to my satisfaction. The only catch is that they were all take in RAW and had NR done to it.

Yours being jpeg's straight out of the camera, and that too with NR off in camera intrigued me, as I was never, and still unable to do that.

The K-x is better by about one stop (may be more) and don't have to use RAW for family snaps, and faces look better at iso 3200 with the K-x than the K-7 in all samples I've seen. This is the only reason to consider that.

So, I am very happy with the K-7 iso performance, always have been. But, it is the jpeg performance, and the ability to use iso3200 indoors and get the required shutter woith my f2 and faster lenses (I have four of them) that got me to look into it deeper now.

Yes, I was wondering how many would pick up on that. This is the reason this photo impresses me on a number of levels, the slow shutter speed at an effective 630mm - 300mm x 1.4TC x 1.5crop @ 1/60sec and also the way the noise cleaned up perfectly with Noiseware Professional and the amount of detail even with the 1.4x TC on the DA*300.

Thanks for the nice comment.

K20D with the Tamron 18-250, ISO 4000

These are about 50% CROPS and I used noise ninja.

K20D with the Tamron 18-250, ISO 64000

The K2OD impressed me. These are older images that I am just getting to. These I took at the Orange County fair and was bummed I was not better equipped lens wise, Still the tammy did ok. I did not know the Fab4 was to be playing, but was lucky to get nose bleed seeds....The conditions where bad and focus was all manual..I used noise ninja to clean them up.
All exif intact and I pretty much maxed out what I had...

I posted basically these in my thread:

Kx in Use

Since it is relevant - I'll pasted it here -

Over the past couple of weeks I had been taking my K-x to a pretty dark jazz venue to a super gig where lots of musicians come to sit-in jam - it's both great music (otherwise I wouldn't go) and a real challenge for any photography.......

This past Thursday Christmas Eve they had a short session and it was pretty dark - but seemed more so than usual - I think they had some of the lights on dimmer settings.......

Anyway excuses aside - I knew enough to set my auto ISO to ISO5000 max - and of course all of my shots were at ISO5000 -
here's an overall scene setting shot -
(all should have EXIF re-attached)


ISO5000 1/50 f/3.5

As one can see the lighting is very challenging - bright spot for the center and hardly anything for the back of the stage.

Probably can't be seen on the overall shot - but there is a bass player behind and perhaps just barely visible past/below the right elbow of the trumpeter (stage front center). This guy -


ISO5000 1/13 f/4.5 - this is starting to get pretty seriously difficult -
in fact this shot shows some blurring (subject movement) so I had to over-sharpen it a bit.....
the amp/speaker bottom left should have been blurred a bit PP - but I'm too lazy - and this actually shows how well the K-x and its SR are working........

You think this is low light - the musicians have a a tendency to play supporting parts off-stage (told you this was a good gig) - as kind of shown in this shot -


there's a trumpeter and a flugelhorn player to the extreme right
ISO5000 1/13 f3.5

So this one is pretty darned seriously low light (for me) -

this would be past the right of the previous shot off-stage in the audience area where there was only candle light and reflected light (as the front tables which were relatively "well lit" show) .......
ISO5000, 1/4, f/3.5 -
yes I was lucky - that the K-x SR worked so well, and the subjects didn't move so much....... (yes, I had plenty of blurred shots - this is a stupidly slow shutter speed - but hey, that's what I have to put up with....)

But I can still get shots like this one -

ISO5000, 1/40, f/4
If one looks with PhotoMe the original thumbnail shows the face very much in shadow due to the cap the player was wearing and the light high and above the peak. So I selected the face area and upp'ed the brightness and contrast.

High ISO images are my thing.

Since I don't like to use a flash when I shoot people (due more to my own technical limitations), and I am usually indoors, most of my people shots, I seldom shoot below ISO 800. The link below to a page in my gallery is almost completely filled with high ISO shots.

People - Sky of Texas Photography--Michael Lunceford

Here are a couple of examples:
K20D, FA 50mm f/1.4 lens, f/2.0, 1/125, ISO 1600
http://www.skyoftexas.com/First-Impressions/People/IGP1787-copy/554225696_BYqha-L.jpg

An accidental use of ISO 3200 (which I seldom use) that came out okay

ISO 800 with K20D and the DFA 100mm lens at f/3.5
