K7 vs d3. Comparison!!!

YouTube - PENTAX K-7(5.2 fps) vs Nikon D3(at?5.0 fps) shooting with LENZ

**Ash** · 05-26-2009, 04:25 AM

Yep, we've seen this one.
Discussion's centred around how the K-7's rate is slower than 5.2fps and the D3 is clearly faster (by this video).
Although the K-7's shutter sound is much better dampened and slick.

oh sorry! i didn't, but it sounds really quiet indeed.

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...?

... or the shutter speed is too low.

leadbelly · 05-26-2009, 08:42 AM

when they say "5ps or 9fps" what is the "minimum" shutter speed to get these figures? 1/125?

WerTicus · 05-26-2009, 10:28 AM

speed is not important to me at all

and the k20d already has better image quality.

Excellent point. It was indoors. That also might explain why the D3 was much slower than its maximum as well, if both cameras were limited by the slow shutter speed.

offertonhatter · 05-26-2009, 02:28 PM

don't care, the K-7 is better than my K20D, so if I had the money, I would have the K-7 for most work as it is excellent, and maybe a D3 for fast fps when I need it.
But I don't have the money so I will stick with my K20D and save up for the K-7........

(does the jealousy come through? hmmmmm, Okay I would love both....... ;-) )

looks like the K7's battery charged is low, you can see it slowing down.

cheers,

Rene

They really should have used a full battery with each, and set them in manual to shoot small jpegs at 1/1000 with the lens wide open. That would effectively eliminate all the variables besides the speed of each camera's shutter mechanism and show what each can really do (in which case the D3 will trounce the K-7 at 9fps but who expected it to out-burst Nikon's $5000 fastest?).

Theoretically at X-sync (1/180s for the K-7; 1/250s for the D3...)

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

I'm not sure battery charge levels have anything to do with frame speed, or any other function. If there's not enough power to perform the function, it just won't function.

Anyone who has tried different types of AA batteries in a K1xxD/*istDx knows this is very far from true.
