Burning Question! Just what is the difference between the above brands for the ''same'' Lens?
Looking at the 70mm - 200mm F2.8 AF-S on the internet, Sigma and Tamron are half the price of Nikkor, Is this because the quality is lower / significantly lower? Or just they aim for a different segment in the Market? Has anyone used and can provide feedback on the Sigma and Tamron versions of this lens? How do they compare to a Nikkor one?
