Possible to make 50mm look like 30mm?

Im sure this question breaks all types of terminology laws but in the case that I cant buy a 30mm lens this week is there any way possible to get an identical picture with a 50mm lens? Would stepping back away from the subject work or is that a bad idea? I need a wider view, what can I do in this emergency?

Huh?

If you want a 30mm to have the field of view of a 50mm, you would step closer, not back. If its too close, there might be some distortion.

i want my 50mm to have the field of view of a 30mm, so its the other way around.

Essentially im asking if its possible to get the look of a 30mm with a 50mm lens.

No because if you move, you're changing the perspective...

Turn the camera 90 degrees from how you would want to frame the shot, then shoot a 3 shot panorama image larger than just the 50mm, then stitch together in post and crop back to 30mm as needed

this... You'd typically best be shooting in manual (manual focus, manual speed, manual apeture, manual white balance) as letting the camera do anything itself often results in some pretty scruffy results. Oh and you need to work out the best "rotation" point also so that you don't get big distortion that can't properly stich.

you can try and step back to get a wider view...the perspective will change, and you'll run into an instance where you can't step back anymore....

Well im trying to take video...that kind of changes the game here.

Get one of those screw in "wide angle" adapters

Quality wont be very good but you might be able to pick one up at a local photo shop or even a best buy...But for video the fact the quality is not as good as with a bare lens might not be as noticable (Because video moves for one, and for two video is only about 2mp or so)

why? the stiching is going to take a bit more effort, but you should still be able to achieve that 30mm wideness....

how do you stitch videos?

why not just pick up a cheap lens that goes to 30mm...

frame-by-frame!

Not sure if Joeseph is trolling or not but I dont have time to stitch 100+GB worth of video clips lol, I bought a decent 30mm and will just sell the 50.

He is trolling. Technically you probably could stitch video if you record all I frames, but you still can't actually do it unless the subject is completely static. Or are you planning on having everyone/thing in the video perfectly recreate their actions two or more times?

Stepping back is your only hope, but that just lets you capture the same basic scene. The resulting video will still feel very different when you view it... more "narrow" and unnaturally compressed. It might get the job done, but a 30mm would likely do it much better.
