Will I regret not going the extra mile and buying the D500?
You might, but you need to be clear what the extra cash is getting you – another 2fps continuous shooting speed, an even larger memory buffer and Nikon’s latest high-tech 153-point autofocus system. The D500 is also built like a tank and uses Nikon’s professional control layout, and is slightly more responsive. The D500 has twin memory cards slots (1 SD, 1 XQD) whereas the D7500 only has one, and although its LCD is the same size, it has more than twice the resolution. You’re paying a lot more money and you’re getting a lot more camera, but the D500’s advantages are all geared to the rough and tumble of a serious action photographer’s lifestyle.
The bottom line: The D500 is worth the extra only for sports fans and pros looking for a second, speedy DX-format body.
