My heart is a little sad to think of selling what I felt was the holy grail of lenses for me. I shot the last couple years my kids HS sports with it. The pictures, especially in daylight, were stunningly sharp and I was very proud of them. Now it is in it's second year without coming out of the case. I am looking for some advice/consoling on what to do with a lens that I want to justify keeping. But, the frugal part of me says not to keep the money tied up in tech that will become obsolete eventually. Am I just struggling with the sentimental value because of the pics taken with it? Probably just need a professional to tell me I am a dumbass.
