Which is better, Nikon D7 100 or Nikon D750?

Hello, my friend, I'm a photographer. First of all, considering the price, D7 100 is a half camera, which is much cheaper than D750 full camera. Secondly, in terms of image quality and playability, D750 is the first choice, with high image quality and sense, and with its own WiFi function, the photos taken reach professional level and are richer in color. Thirdly, in terms of use, D7 100 half-frame machine can meet the needs of daily and family life. Fourthly, from the perspective of upgrading, if you play D7 100 half-frame machine for a long time, you will feel that you can't meet your own requirements and want to upgrade to D750 full-frame machine. Therefore, in order to reduce the tossing of money in the future, it is suggested to buy a D750 professional machine directly, so that you don't have to toss it in the future, and you can save money to buy more good lenses. Finally, I wish you a happy photography and a beautiful life!
