Re: ISO 51200 of K-3 small sample image - not too promising regarding high ISO IMO

I think I'm ok with images not being amazing at 512k ISO.  Obviously it'd be awesome if they were clean, but honestly that looks a bit like my K20D at 6400, so I'm not going to complain.

It's called coarse grain film look

And if one thinks outside the box, with just one click those ISO 51K images can become amazing B&W captures in the best spirit of fast film photography.

In my opinion the key is shadow noise at 6400 & 12800.  If that is fairly clean I can do a lot of low light (or fast action) stuff with the cam.  Maybe it can be cleaned up enough for cropping with something like Topaz as well.

Cheers.

Why anyone expects anything other than a result like that at ISO 51,200 escapes me.  It's amazing that it's on offer at all, but it was never going to be really "promising".  We've come a long way from ISO 25 speed film, or indeed slow speed digital, but the improvement cameras can offer in high ISO performance seems to be hitting diminishing returns.  Until someone makes a new breakthrough in sensor technology.......

Well, who really shoots regularly at such a high ISO ????Those ISO are just there for nothing, i'm more interested at results in RAW up to 1600 ISO.

Night photos?

Or super high speed photos?

Or super long teles that are hand held in dim lighting?

But ... as you say .. it i snot for high quality photography.

One interesting way to shoot with high ISO is to do so to get high enough shutter speeds for hand holding, taking multiple images of the same static scene, and then stacking the images in PP after alignment to create a final low noise photo. I just wish this was able to be done in camera in a Pentax DSLR as it is possible with the Sony Nex 5n we also have. Of coarse, you give up raw output when the camera does the stacking, but sometimes I just don't care, and just want the shot.

Thank you

The good news is, there's no obvious banding.  Maybe a slight hint of a periodic horizontal feature in the wood areas, but I'm not at all sure of that.

You don´t need to think about these pictures with highest iso.

NO firmware is over 0.8!!!

I know that there are using today 0.35 and 0.50!!!

The last step was so ugly,looked like a overheating K10

We have to wait,that´s the reason we will not see big pictures till today in high iso.

best regards

Yep, and to reiterate, DPreview's J Keller should be loath to have written the asinine* comment about AF speed using such early FW. Pretty ridic.

If extra time was allowed to add sense and scientific observation into such sentences, the reviews would never come out. So they take shortcuts through wast fields of lack of common sense.

They did the similar gaffe with the E-M1 "review", by drawing on an impression from the back of their mind (and not checking in real life) what was the speed in focusing of the 4/3 lenses on older Olympus E bodies.

Yep,  No use even looking until firmware is near 1.0.  Regardless of the maker of the sensor, Pentax has always done a lot with on-chip & after chip processing.

I feel what's really  not too promising is that you're trying to pass opinion based on an image that size...

Is there an advantage to that over simply using a longer shutter with lower ISO?

At over 8 frames per second you can easily take a sequence yourself.

Those kind of ISOs are simply amazing. It's a wonder we can get them at all.

Re: Who really shoots at 51200 ISO ???

K3 has multi exposure mode ( as did K5 and K10d )

http://www.ricoh-imaging.co.jp/english/products/k-3/feature/03.html

The K-3 allows you to capture the desired number of images (two to 2,000) and synthesize them into a single, eye-catching composite image with great ease. You have a choice of three synthesis modes to obtain the desired visual effect.

Average

  • Since the K-3 calculates the average exposure level of captured images, you can create a normal-exposure composite image without resetting the exposure for each image. This is the simplest mode for enjoying the complicated multi-exposure technique.

Accumulation

  • The exposure level of all captured images is totaled to synthesize a composite image. When you under- or overexpose certain images, the brightness difference in these images is reflected in the resulting image.

Comparative Brightness

  • The brighter areas of captured images are averaged in a composite image, while the darker areas are expressed as they are. This mode comes in handy when synthesizing subjects such as the moon, fireworks and illuminated buildings into a single image.
