Just wondering if you can help me out please. Do you consider the 150-600mm image quality as good as the 70-300mm vc lens, albeit twice the focal length?
The reason I ask is that I have had the 70-300mm for a long time now and consider it to have excellent image quality ( for me anyway ). I also have the Sigma 150-500mm which is ok but doesnt come close to the 70-300 at ranges where they overlap.
I mainly shoot birds and also have the 400mm 5.6 but need something with more range at times hence the Sigma and the interest in the new Tamron .
My copy of the 70-300mm even gives the 400 a run for its money (IQ wise not AF) so was wondering if the bigger Tamron is comparable?
