I am owning this Lens...as also 4 others. The Lens is really nice, but I have only used 2 times...not more. It is an entry Level, but the image quality is really nice. The 300mm zoom creates a really dramatic DOF. The Limitation of course is the Aperture. This is 5,6. Significally less than the 2,8 (2 Stops difference). If you would like to use it for indoors Portrait this would not be so easy with available light. For Wild Life is really good. As a final tip, I can say that it is value for money.

I own this lens. The lens is really nice, but I have only used it twice. It is an entry level, but the image quality is really nice. The 300 mm zoom creates a really dramatic DOF. The limitation of course is the ƒ/5.6 aperture – significantly less than the ƒ/2.8 (2 stops less light). If you would like to use it for indoors portrait this would not be so easy with available light; however, for wildlife is really good.
