Highlight problems were most common 10 years ago with the first affordable DLSR cameras. It has become much less of a problem with cameras produced over the past 5 years, at least with the ones I have used from Canon and Nikon. One can use a custom curve with a camera that will affect how it records highlights but with the Nikon this is done dynamically with the Active D-lighting function. It creates a profile that is then applied in post processing.
This all assumes that you are generating RAW files and not JPEG ones. I did a test a few years ago when I first got a Nikon D3. I did dozens of shots with each one bracketed by 1 EV so I had 100 or so files with a third at -1.0 EV, a third at 0.0 EV, and a third at +1.0 EV. These were pictures of a bride and a groom and had whites, blacks, and reds (the most difficult color to deal with in post processing), as well as skin tones.
The -1.0 EV were the worst in terms of color fidelity when adjusted with ACR and imported into Photoshop. What I found and had not expected was that in more than a few situations the +1.0 EV or "overexposed" shots were the best in terms of color rendition after adjustment in ACR for the exposure.
One reads how much data is lost with underexposure but this experiment made it abundantly clear that even slight underexposure at the "correct" 0.0 EV settings resulted in lost information and this was visible on the screen when reviewing the images. I then realized that unlike with the older cameras where one needed to slightly underexpose to avoid blown highlights and loss of detail that the greater concern should be to not underexpose and lose valuable color data.
I would expect any photographer to be looking beyond the camera and considering also the available lenses for the camera from the manufacturer and third parties as well as the flash options available (greatest with Nikon, seconded by Canon, and nada for others). I like having Canon eTTL or Nikon iTTL compatibility with my Quantum Qflash location lighting and doing flash EV output adjustments wirelessly in 1/3 EV increments at distances of up to 600 feet with 100% reliability. I would be comparing the Nikon 610 with the Canon 5D Mark III.
