Sigma 50-500mm at 500mm is actually shorter than 420mm
Bought a brand new Sigma\'s new 50-500mm OS on 1/20/2012 from Amazon. The lens is well made and sharp. I decided to do a shoot out of this Sigma and my Nikon 300mm f4 AFS, NIKON 1.4 TC and 1.7 TC.
What a surprise when I found that the Sigma at 500mm is still much wider than Nikon 300mm f4 plus 1.4 TC ( which is only 420mm.) My subject distance s only about 7 feet, I need to move my 300f4 plus 1.4TC setup a foot or so away from the subject to match the Sigma\'s view.
My estimate for the Sigma 50-500 OS lens is it is probably a 50mm to high three hundred something lens. I don\'t think it can actually make 400mm. And they want $1700 for such a thing with Nikon 70-300 sell for only $600?
Needless to say, my impression of Sigma is worse than low. It\'s a company with dishonest practice.
