Can anyone tell me the difference between these lenses?

I have no idea if they are the same lens or not, just one is £70 more, I've tried google but haven't come up with anything really, please help

Oh, the top two in the link btw

Same lens- amazon cheaper than other seller

Yeah, that's what I was thinking, but I just thought it seemed a massive price difference.
