Well... I went off to my local camera store and bought another one, for actually a good price, about $105 (also bought more film too!). But when I got home, I was fiddling with the two pieces and after studying them for a few minutes managed to piece the lens back together again.
Everything works as before now, except the Autofocus gears are a little noisier. The optics are the same and the quality, (as judged on a 2 inch screen), appears the same as the shots from the last shoot.
I will test it out the next day or so and see if it is worth returning the new one I just bought.
