Absolutely. Like the man said, "Ya pays yer money, and ya takes yer choice."
For long reach, I'm willing to sacrifice some IQ for convenience.
But to get even close to the amount of reach offered by the HX400V, I would need the OMD EM5 II, plus the Panasonic 100-400, which would give me 200-800, times two, if I am will to use digital zoom, which would result in 400-1600 mm e. I have been tempted by this combo, but I don't know if I could successfully handhold it. (The OMD combo would be nearly three times the weight of the HX400V).
