Looking to upgrade my Nikon D5100?

I have been taking photos for 3 years. I recently did my first 3 weddings. I quickly found that I'm ready to upgrade my Nikon D5100. I'm looking for a camera with better low light performance, more options for white balance, full-frame, and overall better quality. Any recommendations? I would prefer to stay with Nikon I believe.

It's natural to want to upgrade but you also need to review why you think you want a "better" camera. If your photos aren't satisfactory, it may be that you aren't using all the potential that your existing camera is capable of.

For example, if you set your D5100 to shoot in RAW format, you have a world of control (during editing) over low light situations, white balance, sharpness, contrast, and a lot more. And, of course, your lens play a big part in low light performance and image quality as well. A new camera, even full frame, will not magically give you better results.

Of course, if you simply *want* a new camera, then that's a good enough reason. We've all been there and done that.

I did state several reasons I want a better camera. I didn't just ask out of the blue. I know what I want in the camera, I just don't know which camera best offers it.

Both Alcapone and thankyoumaskedman cover your question pretty well.

The advice to explore your D5100s RAW capability is spot on, the D5100 has the same sensor as Nikons D7000 and that's capable of top quality images (many Nikon lovers consider the D7000 to be one of their best efforts) If I was in your position id maybe upgrade to the D7000 or D7100 (even pick up a used D300) and see how you go from there, if you are convinced full frame is what you want then the D750 is the way to go.

I use Nikon crop sensor cameras myself and don't have any complaints about the performance. The latest and greatest camera from Nikon isn't going to improve your shots by that much so id have a look elsewhere to get an idea of why I'm not getting the results from a pretty decent camera.

Go to htpp://bhphotovideo.com and look at full-frame Nikon dSLRs there.

Go for the D750. Amazing low light and image quality.

I don't know Nikon can't help on the bodies, Just looking at this from a different angle. You don't say what lenses you use. One way to dramatically improve the low light performance of your system would be to upgrade to faster lenses. A stop or 2 gained from F/1.4 primes and f/2.8 zooms is a stop or 2 lower ISO.

The D750 is a good choice. It shoots 14-bit RAW, has great low-light AF, very good ISO performance; pretty much everything you'll need. Sure, there's the D810 with it's high MP sensor, but consider that the higher the MP count, the larger the files which will cost you more to processes. The larger RAW files from the D810 will be better for printing very large, but the file sizes will slow your workflow way down and will require a much faster computer with a larger storage solution for your working and backup drives. Plus your customers won't tell the difference anyway, so why do it?
