K-5 vs K-7 First ISO performance testing (ISO-6400)

Indeed. It looks to me that the K-5 is at or above the level of the D700 or 5DmkII.

hm

spoilsport.....But I admit, this won't make many CanoNikonians switch to Pentax. However, this will prevent many pentaxians from hopping to the other side for noise (as many said they'd do if....)
Maybe a few previous shipjumpers may return....

Also, if this is a true to life sample (which I assume it to be), then this means that 12,800 is more than likely completely usable. It looks like it has about a 2 stop advantage over K-7. That is about what I would expect to get out of iso1600 on K-7. Booyah, grandma.

If this is 6400 you should be able to use 12800 indeed and I am thinking that for use on the web 256000 may also be good enough for an illustration of sort (max width 800 ).

Do we have any RAW images for comparison?

Straight out of the K5 camera RAW files vs. JPEG's// vs. the K7?

No way. Different exposure and lightning conditions.

And I can note how bad auto WB of D7000 works...

Pentax's auto WB works in artificial light MUCH better.

100% crop from D7000 at ISO3200

Looks like the K-7 at 3200 iso.

The performance of the new sensor really looks amazing. Very low (and pleasant) noise, with superb detail retention. The K-5 output looks like it came from a current-generation full-frame sensor. I agree with those who say that the D7000 photos look worse due to rather horrid detail retention, but in the end I am sure that the RAW output from both cameras will be very similar. If so, Nikon owners should be quite pleased to see these K-5 results, since the new Nikon should be able to do just as well.

It would seem that the pre-announcement buzz about a big jump in APS-C high-ISO performance was not just hype. This is quite exciting.

ISO800- D7000

ogl · 09-24-2010, 08:18 AM

it's not the end

ISO1600 crop

ogl · 09-24-2010, 08:19 AM

It's JPEG from UFRAW default without any NR.

StepOne · 09-24-2010, 08:21 AM

Is there any k-5 sample that show EXIF info?

vizjerei · 09-24-2010, 01:26 PM

Very nice, Pentax, Very nice!

Why this particuar crop???

Wow, looking at that I'd have to say my lowly K-x is licking the D7000 when it comes to higher ISO!

Well these are no doubt jpg processed image.
I suspect RAW's will look a little better with respect to grain.
Though I have to say... based on these samples, I'm really starting to think that Nikon and Pentax may not be sharing the same sensor after all...
