Don’t close the memory bay door when you take a card out. So you know you need to put one back in when you pick it up to head out.

Jump around tutorials for specific effects and those will in turn teach you the capabilities of the numerous tools available

Especially where more modern cameras can handle cranking up the ISO higher without completely cooking the picture in low light. f/2.8 to f/4 is a loss of a single stop of light, it is now a relative non issue to bump up to compensate. Which even then, also worth considering how your images will be viewed. Even if there’s some noise, if how you share your images means someone is only going to see it as a 3x2" post on their phone screen, isn’t gonna matter a lick. You can even miss focus a little bit if that’s the case lol. Only other photographers are going to look that close.

24-105 for a long time was my “only take one” lens. If I was shooting at like conventions or something and I didn’t feel like carrying a bunch, didn’t need super shallow depth of field, and could use that extra bit of telephoto when I needed.

It is the walk-around lens. It’s also great for video.
