Is Nikon d7 100 plus 50 1.8g enough for portrait photography?

Enough, the equivalent focal length is 75mm, which is in the best portrait focal length (60-80mm). This focal length is the most realistic, the distortion is the least, and the background is blurred enough. The only drawback is that you can't show the full-length portrait in narrow indoor shooting, but indoor bust, close-up, outdoor portrait and so on. Are competent enough and the imaging resolution is convenient. Don't worry, there is no dog head in the fixed focus. Remember that it is best not to open the aperture, but to close it a little.
