Okay so I've decided to delve into the world of adapting older, manual lenses onto a Canon EOS body. My question is; which of these lenses is better? On eBay they're both about the same price. The only differences in specifications is that the Chinon is a 50mm f/1.7 and the Takumar is a 55mm f/1.8. Which has better image quality? I'm leaning more towards the Takumar but I'm not sure.
