Sorry to bother, but I looked up this lens an its called a Macro lens. Why is that? Priced quite well, though.

It has a macro switch which extends the focusing range
so that it can be used as a macro lens. BTW, this switch has
an annoying tendency to stick in the macro position. At first
I thought it was a fault with my lens, but it turns out they are
all like that!

It isn't a true 1:1 macro lens, I think it manages about 1:2.
If you stop it down to f/8 or less, it is quite sharp.

So if I'm fully zoomed out and focussed on an animal far away, and switch on the marco, would it magnify the shot??

Sorry about the silly question, just wondering what would happen.

If a lens has a special macro switch then it is used to enable close focussing. So all that happens if you switch it on is that the focus can slow right down for distant subjects if the camera starts hunting.

It doesn't magnify distant objects.

No. It effectively moves the end-stop at the close end of the
focus range. Other than that, it doesn't change the optics in
any way. The macro switch can only be engaged at the long
end of the zoom range. Even in macro mode, the closest focusing
distance is just under 1 metre. This is ok for outdoor shots, but it
is an annoying limitation when working in a confined space.

I currently have the t2i and the canon 70-300 is. I like this package for the $$ invested .I also have access to a buddies 100-400 L series which is a really nice lense .In Canada the wildlife i shoot is basically non predatory so I use my 25+ years experience of archery hunting to get myself relatively close to the subjects I want to shoot and my 70-300 works absolutely fine for that.Where you are if you subjects are dangerous? maybe that would not be suffice? If you are shootting non dangerous wildlife , work on your hunting skills to get in close to your subjects?
with 18 mp you also have the ability to pp crop your subjects some with good results .I am 100 % amature but this what I do.

Thanks for this. I am in Kenya, and the wildlife is wild...literally. Its a little tricky trying to get too close to them, and also I shoot in national parks, and dont like to go too far off road as its not really good for the environment.

I suppose a 300mm to start with should do, and then if I need more, I have no choice but to buy.

For Canon you get Tamron 70-300 (macro 1:2 selectable from 180-300) for less than € 130=$185 incl 20% VAT

That looks like a good lens. I've also seen shots from a Tokina 80-400 here on these forums and it looks good too.

I wonder if it can be shot handheld?

you can actually get the kenko TC 1.4 to work with the ef 70-300, but it is a bit slow to AF at the long end of the zoom.
