The Nikon D7500 is 20.9 MP DX-format CMOS image sensor WITHOUT an optical low-pass filter. If offers up to ISO 25,600 and you can also now expand the ISO range up to 51,200 and has 4K video like it's big brother the D500. Looking to capture birds in flight, well then you will love the 8 frames per second and a 51 point auto focus system. Need to see better well the Large 3.2” 922K dot, tilting LCD screen with touch functionality is a nice added bonus.
