I needed a tele lens for my DSLR APS-C content in a price given the low use as I have. The objective is well finished and inspires confidence. In photoshoot I am very satisfied of the first test and in video mode or little you hear the engine of the MAP. The stabilization is effective. Of course it does not constitute a cannon f / 4, but for my traveling is easier to carry !!!! used on a Canon EOS 70d.
