Given that you get a higher frame rate when you attach the battery grip to the D300 due to higher level of power available, I would suspect it might have SOME impact...

I don't see how they can compare the D3 to the K-7. They are entirely different categories.

I agree and i woudn't either but the guy is just comparing the fps. Price tag can't be compared either

Wouldnt frames per second depend on shutter speed in burst mode?

Agreed K-7=$1300 / D3=$4400, I would think for another $3000 it would be better & faste. Thats just me.

Agree with you too, Pat - and if that test was scientifically accurate, I couldn't justify spending $3k more just for .7 fps faster shutter speed. (according to Alcazar's post on the first page)

Either way, 2.5 fps is already fast enough for me - but the extra speed I know is important to a lot of people - so that's good news for those people.

Only if the shutter speed is low. For any reasonably fast shutter speed the fps would be the same.

I measured the rate of the cameras in this video (not with a stopwatch but by opening the video in a sound editing app)

the Nikon has a rate of 4.97 fps, while the Pentax has a rate of 4.22 fps in the first run and 4.00 fps in the last run.

I know the Pentax is supposed to make more than 5 fps, but isn't the Nikon supposed to make 9 fps??

The question is if the lower rate of the Pentax is due to the unfinished firmware, or maybe the memory card isn't fast enough...?
The D3 has a high and a low burst rate that can be configured individually, thus it may or may not run at 9 fps.
Provided that you have your AF settings and release setting right, then it will do AF-C bursts at 9 FPS and MF burst a little faster (11 fps IIRC)
But you need to have the camera set up right to make it perform and it does take a while to get that right.

Yup, but I plan to run the K-7 alongside my D3s anyway

I would think so too, faster at least.
Better most of the time too, but I regularly have assignments where the size of the K-7 would make it a better or at least a more convenient choice.

Thanks for that.. I went checking around to see if there is a minimum shutter speed to base such a test on but couldn't.

Would you have any idea?

Also when checking I found this reply by JCPentax in another forum

Depends on the shutter speed. If it is fast enough it is firing them at 5.2 fps.

Cheers

I went a little nuts with my K20D on Saturday. I've manage to reduce 2k candid pictures and 300 portraits to 883 candid and 187 portraits. Will the faster burst speed of the K-7 include any tools to help me improve my frames per second while processing the results of wanton abuse of shutter?

Indeed!
It may just mean that people reach the 'end-of-life' 100,000 actuation milestone quicker and need to replace their bodies sooner.

Good for Pentax.

Yes good point.. and there will be the push to take 3 hdr shots to produce 1 x image where possible...

Here's Russian K-7 presentation video:
http://www.youtube.com/watch?v=C-PDwlMYMqY

I took audio track from this video and loaded into audio editor, so it was very easy to calculate frame rate of the in video.

Guy has made total of 16 shots in continuous mode there.

First shot started at ~1:18.9, sixteenth shot started at ~1:22.7

So, 15 shots where fired in ~3.8 seconds. That makes 4fps...
