ISO 8000 rocks!

After seeing so many complaints about technical problems with the K5, I had to post this.

I shot an outdoor theatrical event this week that had very dim stage lighting. Since the rehearsal was in progress, I couldn't use flash so I bumped the ISO up to 6400. Still not enough so it stayed at 8000 most of the night and up to 10,000 for a few shots. After a little work in Camera Raw and some touch-ups with Topaz Denoise 5, I got dozens of very good, publishable images. Very happy client and very, very happy K5 shooter.

Yes, performance of k-5 sensor is top notch.

But, the problems that have been posted here are not connected to the Sony sensor. Sony sensor + Pentax Image processing has been fantastic. Problems have only been with the rest of the components that Pentax is responsible for- electronic circuits, physical buttons, AF algorithms, Flash algorithms, sensor assembly, etc..

General IQ is fantastic but it has little to no co-relation to the problem components.


cheers,

Abhi

I agree. I've done the same. I love my K-5s. Flash is not only frowned uppon in many places, but kills the mood. I can't wait for even more imporovement to sensor ISO performance so we can use even faster shutter speeds in low light conditions.

Despite the risk of being flamed by the "Squirrel Haters" lurking at a chance to knock my Squirrels.....I will post this one I shot yesterday evening, at ISO 12,800...no NR applied.
Yes, it is nice to get some speed (1/250) by bumping the ISO, these critters are often jerky and move fast.....well, not the fat ones, but some of them are pretty agile.
Regards!

For those allergic to Squirrels, here is a little Birdie I shot at the same time.......also 12,800 1/200 also no NR.

I've seen some from others much better, but these are plenty good enough for an old Squirrel shooter......

BTW- I love my K5 and am not ashamed to say it right out in public! And ditto for my Squirrels!

Nothing to write home about. Just an ISO 40 000 JPEG, resized. Most of the time I am too lazy to shoot RAW and PP the hell out of them.
And AFC.... has better eyesight and reflexes than I do. This thing is pretty good.
Shot with DA* 60-250. in very poor light. 1/400. f 5.6 and 250mm.

The noise doesn't detract from the mood of that pic though.

Oh the jealousy is burning deep!
K-7 ISO 6400 (No PP except Raw-Jpeg conversion) not that this would be retaining much detail if i used noise reduction


Same shot w/ Noise reduction and other PP actually came out ok, still lacks detail and looks pretty soft but could be printed small
