Over the years I have come to like certain features designed into lens'.
One, must have, is a fixed f-stop. I really don't like lens that change there f ratio as you zoom them.
Sometimes you just don't have a choice. But fortunately, most of them are lower quality consumer lens and not “L”.
Second I really like a lens that doesn't change it's shape as you zoom it. A lot more difficult to find.
Even high end lens' do this.
The Canon 70-200mm F2.8 is quickly becoming my favorite lens of all time and I have been at this for 40 years. This lens has no peers. It is fantastic.
The Sigma 50-150mm F2.8 is running at close second. Not an "L", but not bad at all.
Canon are you listening?
