The Nikon B500 is designed for simplicity. It joins the ranks of the decreasing number of cameras that use AA batteries. There aren't any manual modes, but a solid handful of automated scene modes. But, the simple camera features a 40x optical zoom and 1 cm macro mode that merges simplicity with a bit of versatility.
The B500 uses a 16 megapixel 1/2.3" sensor--right what we'd expect for the price and category, though some budget cameras use a cheaper CCD style sensor. While most budget cameras cut back on speed, the B500 uses a 7 fps burst mode, though that's limited to only one second of shooting.
The B500 is comfortable and easy to use. While using AA batteries might be pricier in the long run, some consumers prefer them because you can find them at any store, a handy feature for traveling. Despite the lower price point, the B500 includes lens-based stabilization and wi-fi.
So what does the B500 sacrifice for the lower price? The camera will have more trouble in tricky lighting, with a limited aperture, low maximum ISO and slower maximum shutter speed. Expect to get good photos on a cloudy day, but less than stellar results in low light or even overly bright scenes. Compared with Canon's budget priced zoom though, the SX420 has a slow .5 fps burst and the cheaper CCD sensor.
While the B500 excels in simplicity, there are certainly a few features that the B500 lacks, to keep the price low. If the price is what entices you the most, consider some older models that have better features but a lower price because of their age. The Pentax XG-1 offers a 10 fps, rechargeable batteries and a 52x zoom. Nikon's 60x zoom, the P610, is only about $50 - $75 more and also offers 60 fps video and a rechargeable battery.
