Should I get an extension tube?

[padrepaul77]

I was looking at a 75-300mm lens for an Olympus E620, and saw one can get an extension tube. I take a lot of outdoor shots - would this be worth getting or am I fine with just the lens? And are they hard to use?

Thanks,
Paul

No. Get your lens first and then you'll know if you need one.
