As expected and widely rumoured, Nikon announced the new D7500 today. This looks like a great enthusiast camera. It is basically a smaller, lighter D500. My only issue is the crop factor for 4K recording. It's a pity they can't seem to manage to get this using the full sensor, especially when Sony seem to have no problem with that, but given the relatively low price of the camera, this seems like a great option for many photographers. If uses the same sensor as the D500, wich has won a lot of praise, so I expect this will do well.
There is lots of coverage of the launch this morning, so here are a few recommendations:
