The most fun with bird photography is the challenge to get a photo of a very active bird. Small birds in particular have a hard time of staying in the same place for more than just few seconds. These pictures are taken with Canon 70D and Tamron 150-600mm. I like this lens a lot. Tamron 150-600 mm lens is cheap compare to the professional and expensive 600 mm lenses but still delivers some great shots. I will share some pictures I have taken with Tamron 150-600mm lens.
