I just bought a Canon EF for cheap as the electronics are iffy. The only fd lens I have is the 50mm 1.8 but it has a little fungus in so I went on eBay and I couldn’t believe the prices. Hard pressed to find a 50mm 1.8 for under £40 and they generally look like someone pulled it out of their cupboard. I bought my 50mm 1.8 for £12 a few years ago. I also got the 50mm 1.4, which I stupidly sold, for under £100. Can’t believe how much they’ve gone up by
