Overcompensation Much?

I haven't posted in a while, so I decided to show you all what I bought for christmas with the money that I received and saved up myself (thanks student loans!) As you can see, it's big. In fact, big is putting it lightly, its massive!

The photo of the bird I took with the lens, and is slightly blurry, but I'm still getting used to the difference between this lens, and my previous one.

And for those who are interested: I had a Canon 18-55mm lens to start off with, and now have the Tamron 70-300mm lens. The 50mm lens in the picture is broken unfortunately.

The lens at its smallest it is next to a regular sized mug.

Comparison between my new lens fully zoomed inc. lens hood against a regular 50mm lens.
