I think both of those lenses are fine, but if the price isn’t very different, I’d probably pick the one with IS so I have the option.

If you are really worried about needing IS, I suggest reading this article from B&H. B&H is also a good online retailer. 99% of the time I shoot in low light, I use a tripod, so image stabilization isn’t necessary and can be detrimental. Have I tried shooting at low shutter speeds with longer lenses in the dark? Yes, but I always bring a tripod in the evening or for indoor portraits now. It’s not likely you’ll be able to hold the camera anywhere near steady enough in those situations, so you’ll either want to mount it or set it down and set a timer.

Like I said, it’s easy to get caught up in feeling the need to buy bigger and better equipment, but if you haven’t touched it, you don’t really know what you need. You need to get your hands on a camera and go shoot first. If you know someone you can borrow one from or if you can rent one for very cheap, it could be worth trying that first.

End of the day, we are considering an entry-level camera for a budget of $600. There are always exceptions that will allow you to go outside that budget and get more/better features, but if you buy big and don’t use it, that’s just more money spent for no gain.

My first camera was a Canon 70D at $1300. That’s a high entry point, but I feel like it was a great purchase at the time. I made that decision after handling a DSLRs for 10 years because my dad always had them. One of those was a Canon 10D handed down to me that I shot on until buying the 70D, the other was a Canon 5D mark III. I was lucky to have access to those, but they were too much camera for me at first.

Before you go spending a whole bunch, commit to a budget that you will not abandon no matter what shiny thing you see (there are infinite shiny things, I know) and get your hands on something you can shoot with. You’re overthinking things at this stage.

Canon R50 is good at $600. Canon R10 is better at $1000. Sony A6100 is good at $800. Sony A6400 is better at $1000. Fujifilm X-T30 II is good for $1000.

You can find even better (though older) cameras (particularly DSLRs) for sale second-hand from people looking to upgrade. Don’t expect lenses this route because people tend to keep them, but a friend of mine just sold a Canon 5D mark III body for only $300. That’s a lot of camera for the price.

Don’t worry about lenses just yet, get your hands on a camera and shoot with the stock kit to see what you actually need. You may even be happy with the stock kit for now. Experts will push and push and push better equipment, but that’s because they are working at a higher level and marginal gains or quality of life improvements are worth it when your work is photography. When you are starting as a hobbyist, as a beginner, those things are mostly distractions.
