My camera had its lens zoomed out a little when its tripod fell and now it is bent to one side and cannot zoom in or out. I have a Nikon D5300 with an AF-P DX Nikkor 18-55mm 1:3.5-5.6G VR lens. Is there any way that I can fix it myself? I've tried moving it back into place--but to no avail. With the fear of breaking it, I didn't push too hard.
It's already broken, there's very little you can do to make it better or worse.
Time for a new lens. The cost of repair would be significantly higher than a replacement lens.
You can get those for $£€ 40 on eBay [even less if you're willing to wait out an auction], because so many people get them as part of the kit, then immediately want something better.
