>>2579760As I know the A6000 has three bundled kit lens choices: The 16-50mm with Power Zoom, 18-55mm, and 55-220mm, with the mm measurements roughly corresponding to how much stuff you can fit into one image (the lower the number, the more ie. 18mm you can capture a wide shot of a long boat, but with 50mm maybe only a middle section standing in the same spot)
If the lens is the 16-50mm with the Power Zoom (your image),
If you shoot in RAW, there will be noticeable distortions caused by the lens, such as darkened corners (vignetting) and stretched out middle (barrel distortion). This is totally normal for entry-level lens, as the expectation is that the budget-oriented consumer will instead shoot in JPEG, which then takes care of most of the above distortions. The A6000 does well in removing these distortions when you shoot in JPEG.
The decision then is whether or not you want to shoot in JPEG and let the camera edit out these distortions automatically, or shoot in RAW and manually edit these things out on a computer IN ADDITION TO much better experience editing photos in general with RAW files.
I'd say, if you're a beginner, shoot in JPEG first, let the camera handle all that jazz, as you'll be more concerned with image composition.
