Yesterday, I managed to drop one of my favourite lenses, a Canon EF 50mm f1.8 II, and it popped apart into two pieces.Â I know this lens is cheap, and plasticky, but its one of the sharpest lenses in my kit bag, and I love using it for portraits, where it becomes the equivalent of an 80mm lens due to the crop factor of my EOS70D and EOS40D.
As you can probably gather, I wasn’t best pleased, and given how cheaply produced they are, I thought it would be consigned to the broken box.
Well, this morning Google was my friend and turned up this excellent link “How to Disassemble The Canon EF 50mm f/1.8 II Lens” by Yosuke Bando.Â This excellent pdf revealed that none of the plastic lugs holding the lens together were broken, and provided a detailed step by step guide on how to dismantle and re-assemble the lens.
About an hour and a half later, the lens is back in one piece, and seems to be functioning correctly, though I haven’t fully assessed whether or not the results are as sharp as they should be.
Hopefully the lens proves to be as sharp as it once was, though I may need to dismantle it again to properly clean the internal elements as I couldn’t find my LensPen this morning.
