Hi all,

I've got the 70-200 F2.8 non IS lens and I'm pretty impressed with the clarity, but not so much the reach. I was looking at getting one of the extenders but can't work out which one. I've been told to get the 1.4 but it might not have the reach I may need, but apparently it's fast to focus and has great image quality. The 2.0 would give me the reach I need but I've been told that the image quality drops considerably and focusing is far slower.

Can I please get your input/advice? They're the same price but quality to me is important even though I'm not even close to being a pro, but I don't want to noticeably "downgrade" my lens quality.
