I know that Tamron is a cheaper version of Nikon and Cannon when it comes down to it but I bought a new Tamron 70-300 mm Di Lens for really cheap off of Ebay that they had said would do fine with a Nikon D40 and was in good working condition. Could anybody tell me if they have this lens and how it is or if you've heard anything about it? I bought it because I needed a lense that could zoom further in on wedding shots such as 'the kiss' and the 'ring exchange' without people knowing my prescence so I'm not ruining the moment. If anybody could help that would be wonderful. I have been working with an DSLR for about 6 months and taking a photography class so I am a newb but I figured it would be a good idea to ask this question where people who know about it would see it.
