While I enjoy shooting with my Sony cameras, the fact that Sony never offered a flip-out screen with their higher-end mirrorless lineup is frustrating. So one either has to live with that, or invest in an on-camera monitor. There are many different external camera monitors available nowadays, in a wide range of features and sizes. Watch my review of the PortKeys LH5 HDR to learn why I love this field monitor so much!
