@Mtt Ken Rockwell has perhaps the best, straight forward tips . Ritchie Roesch’s Fuji X Weekly is great for all kinds of film simulations if you want to try straight out of the camera photography. There’s even an app for quick reference. I’m a big fan of the versatile Kodak Ultramax 400 sim. When manual focusing, I love the Focus Check and MF Assist Peak (red for me). Keep in mind subject detection turned on will disable certain features - can be frustrating if you forget that. Use the Q menu! (If the F has a Q menu). More than anything, enjoy!
