Yet another (rumored) Canon product that folks here at CR (myself included) don't think anyone needs!
In an odd sort of way this reminds me of the situation with the 24-70 f/4 lens - my initial reactions were ... WTF! what's the point here?
5D3, 6D, 600D, RX100
16-35L, 24-70L II, 70-200L II, 100-400L, 50L, 85L II, 135L, 24TSE, 40, 100 macro, 18-55 II, 55-250 II, 600RT x 4
I come here to learn something new, not to learn how bad my gear is - I know that already ;-)!
