Damn it, the Internet ate my post!
I already looked at your EXIF Snook, don't worry about that bit. (It didn't tell us anything we don't already know.)
Brilliant idea with the mirror!
What you have is a perfectly good little wide-normal prime lens, suitable for general purpose photography. A very old model, but none the worse for that.
I suspect that you have a clear(ish) filter attached to it, which should be removed. Find someone to post a picture of the lens (with a phone or whatever) so we can confirm. If so, it just unscrews. If it seems to be stuck, get a friend who is familiar with cameras to look at it for you - sometimes it needs a bit of (careful!) force. But make sure it really is a filter first.

OK, the Internet gave my post back! Here is the original. Maybe since I had to type it twice, someone will read it twice. Or maybe not.
Don't bother with Hawthy's sensible suggestion Snooks. You have already done that. Unfortunately the EXIF info attached to the image you unloaded does not contain the exact lens model. (You typically only get that with newer camera bodies. Older ones only provide more basic information.)
But that doesn't matter. We already know the important things.
This is a 24mm prime lens. On your camera, this acts as a wide-normal lens, good for many general purpose photography tasks, and as good as any other to get started with. Over time, you will add others to it to do different jobs.
The lens is pretty much as described. It is not a true macro lens (i.e., designed for very small close-ups of, for example, insects and flowers) but that's not a problem at this stage. (Some lens manufacturers label everything "macro", regardless of whether it is or isn't. It's just a bit of routine sleazy marketing. I dare say Ford market huge V8 F-150s as "economical", with about the same regard for truth.)
What it is is a perfectly sensible little wide-normal prime. It is a very old lens, long out of manufacture, but none the worse for that.
It's hard to be sure from the piicture, but I suspect that the lens has a clear(ish) filter screwed onto it. If so, you will want to remove that. It should unscrew just using your finger-strength. If in doubt, ask a friend who is familiar with cameras to look at it for you. Or get someone to take a picture of it with a smartphone and upload it here.
