Used Nikon D800 Vs New Nikon D750

I am not a nikon user but personally I would always go with the ability for bigger prints.

I disagree and would do the 750 over the 800 all day everyday and twice on Sundays.

Here is my reasoning.

1. Star shooting and the 750's better ISO performance.

2. I would have to have a MUCH faster computer to handle 36MP RAW file sizes.

3. New camera smell...... :O)

I use the Nikon d610 which is also full frame and costs less than d750.

All other things being equal, the one with the lower megapixel count should give better noise performance on a full frame 24mm x 36mm sensor. This has to do with the physical size of each pixel. Fewer pixels on the same size sensor translates into larger pixel size. Larger pixels capture more light and generate less noise. So I believe the d610 and d750 use the same 24MP image sensor and should be better than d800 36MP camera at high ISO settings. I believe I read somewhere (may have been dpreview.com) that both d610 and d750 have better high ISO performance than the d800 for the reasons stated above.

I'd go with the D750; camera is lighter, technology of the 750 is newer, and you won't bog down your computer w/ the huge files. Bigger pixel size is better than more pixels in my opinion.

Thanks guys! That's what I figured... Actually astro photography really interests me so I definitely want the superior ISO performance (it's been a struggle to get anything decent on my D5100). I also do like that it is smaller and lighter since I carry my camera around on hikes and treks through the city.

The 800E was intended for star photography, but I don't know how well it does.
I shoot a Sony a7r, which uses "almost" the same sensor as the 800, there are minor differences, anyway I love the images I get from it, but I have not really done much with star photography.

As for pixel count and noise, my first digital camera was a Canon D60, 6.5 megapixels on an aps c size sensor, I loved the image quality I got from that camera, I used it for all of my weddings before I wore it out, the only reason I stopped using it for portraits is I have several customers who buy 30x40 portraits, and it just wasn't quite big enough for that.

Anyway that's all I got!

Thanks for the info guys! I have decided on the D750. The smaller. lighter form factor with basically about the same level of image quality sealed it for me. I checked all of my lenses and the only thing I'm really missing in FX is a wide angle. Any good recommendations? I'm looking at the Tokina AT-X 16-28mm f/2.8 Pro FX Lens.

One last hurrah today with my D5100 then time to upgrade!

D750, As JC said, better low light performance. Also D800 files are so large you would have to lower the quality to meet the 25 mb limit here. Heck, I sometimes have trouble not going over 25mb with my 24mp D610.

If you are interested in astrophotography, the Rokinon 14mm 2.8 is a great choice, and its cheap.

Thanks Mark! I am going to order that lens later tonight- it looks great. The trigger has been pulled... I am a D750 owner!

I have no problems with buying 30-40 years old lenses, but in the digital age 3-4 years are aeons. So, altough you can get a new d800 rather cheap (here an offer at Amazon Germany for a new one for 980 Euros http://amzn.to/1gDIxtg), I would go for the D750.

Edit: Good decission!
