It might cost a bit more to get both lenses, but you might be able to find someone who just wants to get rid of them for cheap. Millions of people have bought these, then realized they don't actually like photography, so there are tons for cheap on the used market. Worst case is if you don't like using the camera, you can sell it for around the same price you got it for.
You should also consider how you are viewing the photos, and whether or not you want to have to process the photos to make them look nicer. If they just stay on your phone I don't think you'll notice much of a difference. Also, if you don't want to run raw files through software, it's probably best to stick with a phone, which does all of the editing for you when you take the photo. So, I wouldn't bother with picking up a camera unless you want to make a hobby of it.
>>2792423Zooming changes the volume inside the camera, so air needs to go in and out. Over time dust will get sucked in and accumulate on the sensor, leaving dark circles in all of your photos. This isn't a problem if you can take off the lens to get easy access to the sensor for cleaning.
