I'm going to South Africa next year and would like to get some Binoculars to see birds and wildlife. (I don't mean the human kind )
I have no idea which sort to get as there are so many to choose from.
I have been looking at these:
Pentax 12X50 XCF Binoculars With Case: Amazon.co.uk: Electronics & Photo
They seem quite reasonable and get good reviews...
Although after reading this: Binoculars - Wikipedia, the free encyclopedia i'm not so sure about the 50 for the diameter of the objective lens.
Its all very confusing.
Can anyone recommend some?
I really don't want to spend much more that £100 or is that a bit unrealistic?

In daytime use the human pupil is typically dilated about 3 mm, which is about the exit pupil of a 7x21 binocular. A much larger 7x50 binocular will produce a cone of light bigger than the pupil it is entering, and this light will, in the day, be wasted. It is therefore seemingly pointless to carry around a larger instrument.
Its all very confusing.
