Some people just can't swallow the fact that their L has dropped significantly due to some excellent 3rd party lenses and pretend that they don't care
No pretending here as I could honestly care less. I love my 35L and use it to create images. Images give me enjoyment, not the current used market value. I am also not bothered in the slightest that Sigma has produced a lens that is comparable or perhaps even surpasses the 35L in quality. It just means that there is another great lens out there that can used to create beautiful images, which is great. It's a win-win as far as I'm concerned.
I honestly don't care if my 35L is worth $1K or $500, I just enjoy using it to create photographs.
