On Saturday, I am off the Hong Kong, Kuala Lumpur and Singapore on behalf of my College and with luck will get a day off for bird photography and some tourist stuff. So, I dutifully packed into my camera carrier the 5DIII, 24-105 and 100-400mm. Then, recalling I had just advised a tourist to Europe to take the minimum, I went to the local camera shop this lunch time and bought a Powershot SX50 HS, based on the review in http://www.luminous-landscape.com/reviews/cameras/canon_sx_50_review.shtml.
To my astonishment, the first two test shots I took of my usual test targets with the SX50 set to 1200mm (equivalent), auto and jpeg (before I had read the manual) outperformed the best images I have taken of them with the 5DIII and 100-400mm set at 400mm. Of course, when the SX50 was set to 400mm (equivalent), the 5DIII + L lens won. But, the extra reach of the SX50 at 1200mm makes it better for much of the bird stuff I do. Further, the focus is spot on every time and the IS is simply unbelievable. Here are the second and third photos ever taken with this SX50, compared with the 5D at 400mm.
