Canon SX40 versus Canon SX50

Hi Stephen,

You seem very knowledgeable about both the SX40 and the SX50. I just bought the former, but I'm considering returning it and getting the latter, instead. The only really serious concern I have is the higher minimum aperature of the SX50.

One person left a pretty cut and dry review on Amazon, saying that the camera really isn't a good all-around camera because of the deficiencies with low light level situations. He recommends it only for people who are birders or wildlife photographers.

Can you confirm or deny this? Is the SX50 really noticeably worse than the SX40 when snapping pics in low light, indoor situations?
