>>3471085Lower f stop: less stuff in focus, longer hyperfocal distance, more aberrations
Higher f stop: more in focus, achieve infinity focus sooner, less aberrations, more diffraction
Aberrations are blurriness along the edges of the frame, color fringing, distortion, etc. Diffraction is when the image is evenly blurred across the frame. This isn't a huge issue since your final resolution will be lower than your camera's max resolution, but at f/29 it's definitely limiting your sharpness in a noticeable way. On an APS-C camera like yours I wouldn't go above f/11, and you never really need to either.
For landscape f/8-f/11 should be good, that's where your lens will have the lowest level of aberrations without running into diffraction, and it will keep everything farther than ~15 feet in focus when focused at infinity.
>>3471086 this is a pretty good example>>3471087>the highest F would mean everything would be in focusThat's correct but you don't really need everything in focus, and usually it's not worth it because you'll get diffraction. If you're taking a picture of mountains for example you won't need things that are 1-2 feet away from you to be in focus. Those super high f stops are mostly useful if you're shooting macro or extreme closeups and you want everything to be in focus and you don't have a tripod. If you have a tripod you can just focus stack, which is super easy to do.
Read a few articles about depth of field, infinity focus, macro focus, the exposure triangle and perspective distortion, there's no way we can sum up all of this stuff in a few posts.
