Why Nikon D800 has this huge sensor with 36MPixel resolution and D4 with 16Mpixel resolution, besides the body and a couple of small differences, there is 3G differences between the two?

Why? it just doesn't make any sense at all. I mean what would you buy, 3G D800 with HUGE 36Mpix resolution or 6G D4 with 16Mpix?

My friend just told me, he was going to buy a D4, but now D800 out, there is no reason to spend extra 3G and get good lenses for that amount instead.

These are just some points:

The 36mp camera will only be shooting at 4-5 frames per second. The D4 will shoot at 10fps. The sports photographer will want that 10 fps. (And because it's 36mp per image you're going to need more cards and more storage space on your PC)
The D4 is introducing a new type of memory card. How good this card will be, I'm not sure. The D800 is doing the CF/SD card dual slot...unfortunately...wish they would've added the new memory or made it dual CF.
The D4 battery is suppose to last much longer (Which can be important).
The D4 will allow you to use the new WT-5 wireless transmitter that would allow you to remotely view and adjust settings via your Ipad or Iphone (And many other devices I'm sure). Where as with the D800, you can't. You will be able to tether via the USB cable I think.

For video: The way the sensor captures video is by 'line-skipping'. This creates issues with larger sensors (Although I've read comments that reps for Nikon say it won't be an issue). With line-skipping the resolution you get with your video isn't perfect. A larger sensor means more line skipping...but we'll have to wait and see some real world tests done by average Joes.

I think the D4 is targeting cinematographers and sports photographers. The D800 or the D800E is for studio photographers. I wouldn't get the E version because then you're in moire and aliasing hell.

My 2 cents..

I still don't know why Nikon would do that, I mean keep the price of D800 around 5, so there wouldn't be huge differences or keep D4 little lower. I know an average person wouldn't buy those machines, but when you look at the specs and see 16MP vs 36MP around 20MP differences, and 3G for that going backwards can't help scratching my head and go "What the?"

Battery life, burst speed, sport vs studio... I am not sure that makes whole a lots of difference. again, for a pro maybe, but how many super pros out there vs machines will sell.

I honestly love the full body, so D4 the machine I would want to buy... however, 36MP sensor? dang! If I get me a battery grip, a couple of nice Nikor lenses, I probably still wouldn't be able to make 6G.

Specs are no that impressive shutter speed vs MP... most people will ask more for MP, and that's the cheaper one... and who cares about the new memory, or two different memory slots!

There must be a catch or Nikon just didn't know ho to market those two in one month length... maybe they didn't even want to release D4 after realizing they can do D800, but it was too late?

No, believe me, Nikon knows exactly what they are doing. Horses for courses, as they say. The D4 and the D800 are completely different animals.

ETA: Wait for the Canon announcements. We've already seen the 1D X announced with a surprisingly low 18Mpx, and we *will* see higher pixel count camera(s) announced at lower prices. Not all that different from Nikon's approach. They are seeing different market segments and trying to address the needs of each.

Lets not forget the ISO performance. That 16MP sensor is going to suck up every little ray of light. The 36MP sensor will have a lot more noise problems. Not an issue for a studio photog, but it is for a sports photog.

That's the biggest difference to me, that D4 should be able to pick up tones that even the human eye can't see. I would rather have that ISO performance then all those megapixs. I just hope the D400 will concentrate on ISO.
