AF-S (Autofocus Single) mode is used for still subjects, where the camera focuses once and then locks the focus until the shutter button is released. AF-F (Autofocus Flexible) mode is used for moving subjects, where the camera continuously adjusts focus as the subject moves. Pre-AF is a feature that allows the camera to continuously focus on a subject even when the shutter button is not pressed halfway, which can help reduce the time it takes to focus when the shutter button is pressed. **

The Nikon D3400 would be better suited for use with the Nikon AF-S 50mm f/1.8G lens as it is a Nikon camera and the lens is designed to work seamlessly with Nikon cameras. The Panasonic Lumix G with the 25mm f/1.7 ASPH lens is a Micro Four Thirds camera, so it may not be fully compatible with the Nikon lens. Additionally, the D3400 has a larger APS-C sensor which would complement the 50mm focal length better than the smaller sensor in the Panasonic Lumix G. **

The difference between "you cute af" and "you hot af" lies in the connotations of the words "cute" and "hot." "Cute" typically implies a more innocent or endearing attractiveness, while "hot" suggests a more intense and sexually appealing attractiveness.

"High af" is a slang term that stands for "high as f***," which means being extremely intoxicated or under the influence of drugs, typically marijuana.

The major difference between a Nikon lens AF-P and AF-S is the type of autofocus motor they use. AF-P lenses use a pulse motor for quieter and smoother autofocus performance, making them ideal for video recording. On the other hand, AF-S lenses use a silent wave motor (SWM) for fast and accurate autofocus, making them better suited for still photography. Additionally, AF-P lenses tend to be more compact and lightweight compared to AF-S lenses. **
