Who knows, I might sell my 100-400mmL
I have a 5diii, and I got the SX50 for birding and for my daughter. The superzoom is not DSLR class, BUT, it can reach with decent quality, objects I cannot otherwise without plonking serious cash in lenses for the 5diii.
While I remain impressed with it's reach, what got me was the DR..
Let me explain, I don't mean it has more DR than the 5diii, but that it almost seems to compress DR to fit the camera's abilities... meaning, on a sunny Day with harsh light (high contrast scene); the 5d3 will blow the highlights if I meter for the shadows, but the SX50 does nto seem to blow highlights especially in people shots.. I find this strangely amusing...
(granted in PP I could get the 5d3 image close to what the SX50 does without PP) but that is a separate issue. Right off the Camera, image of the SX50 have more viewable DR than the 5D3 or so it seems.
I am sure there is some Digic mishmashing going on... but I wonder if this sensor has more DR or not.
