d3200 and d5300 are entry level cameras, meaning you will eventually upgrade if you get serious about photography. the d750 and d810 are full frame cameras that give you more control and easier control of your shots when you get more serious about photography. the d4 is a professional camera, usually not needed to get quality photos unless you just have a limitless budget and like to have bragging rights. the most important investment will be your lenses. always invest in fx lenses as opposed to dx lenses. if you purchase a dx camera like the d3200, d5300, or the d7200, the full frame (fx) lenses will work just as well as the dx lenses, but, if you ever upgrade to a full frame camera like the d750 or d810, you will not need to reinvest in full frame lenses and will save a great deal of money in the long run. enjoy shooting.

I am not sure how you came to this conclusion. That high pixel count influence the quality of light quality is not deniable (if you compare same generation cameras) it does not influence the shutter speed at all.

DX is crop, FX is full :thumbup:

There are subtle and not-so-subtle differences. Read comparisons and decide what features are important to you.

If the OP is asking for the differences from this group, the OP is not ready for a high end camera. I don't think if given a side by side review the OP is experienced enough to appreciate let alone understand the differences. There is certainly not enough space here for anyone to even attempt to answer the question.

The solution is hands on experience in understanding the basic functions and features of a camera, lens, filters including a mastery of ISO, aperture and shutter speed Which I doubt the OP has.

What the hoggers will provide are bits and pieces that are based on their own personal experience and preferences. The OP has not provided enough information to answer the question. The budget limit is vague and ambiguous.

My recommendation is to go directly to a camera store and even rent if the OP is serious about making a good selection.

Unless you need to brag with the latest piece of gear hanging around your neck, you can find great full frame high-end refurbished Nikon gear. Check B&H, also Nikon itself.

Start off with a single lens. Use how to see photographically and become a master of the camera. Then invest in more lenses, etc if you have need.

I think the poster meant to say frame rate.

You maybe right.

From what I have seen, the higher end models have two thumbwheels, and the lower end have just one. Having the second thumbwheel is really nice. D70 to D90 and D7000 and above (D100-D300s) have the second thumbwheel.

I can't help but wonder where you are shopping for cameras. My Nikon D800 was roughly $3000.00. That is half of your $6000.00. I love mine but will sadly let it go to you for $2900.00, maybe a bit less.

The D3100 is a great camera, it doesn't have the bells and whistles of the higher end cameras. It was designed for people transitioning into DSLR's . I have a D3200 and use it for a carry around camera because of the light weight. My D300 is double the weight and the D3200 has better low light capabilities. Invest in good lenses and when you upgrade you will be ready.

In my not so humble opinion, full frame is not superior. In fact it is inferior. It depends on what you want. Full frame only has its place because it is the same size as we knew shooting 35mm film. There is nothing inherently sacred about any size. For my uses, the aps-c sensor of the D3100, etc. series is perfect. The sensor is adequate,with good technique to give me images which I can crop fairly heavily and still produce good quality 20x30 inch prints that occasionally win contests.

The cameras are reasonably priced as are the lenses and also they are more comfortable to lug around, better ensuring that I will have my camera and lenses available when the magic happens. I took a Sony a6000 on a Mediterranean cruise last summer. My Sony and I had arguments, (Many,but not all, due to my own ineptitude.) but the images I got are really great. (Can be seen on Smugmug.)

That's not to say that for some people the so-called film format might be perfect. But not for most of us--at least not me.

If I wanted a larger sensor, I would go to the Pentax 645Z with its 52 mpxl sensor. It's almost twice as large as the so-called Full Frame. Or a Phase One back for a 4x5 Technikardan Linhof LOL.

The Pentax 645 Z 100% crop samples are compared here with a Canon 5DS and Nikon D810 FF camera output. The Pentax is clearly superior. Unfortunately it will cost more than twice as much as the FF camera setups.

The digital Linhoff will run about $10,000 for just the body. I can't even find a price or offering for the digital back. I'm guessing it would be more than a Cadillac.
