This lens is very good! Mounted on my Nikon D3200 for a first, the blurry pictures back planes is top! A very good manufacturing (metal), but a bit heavy weight does not bother me. For a beginner, I find that I can adjust well, not too much trouble, take the hand (the same for nikon with electric engine is more than 1,000 euros so no thank you). Thank you to amazon for its reliability and fast delivery.
