Excerpt: I use this product to film weddings but only when I'm in a pinch. It's slow and not very good for low light situations. It is useful when you can't get close enough to the subject (large Catholic Church etc.)
Summary: generates an annoying noise both when the shutter button is half pressed and as well as when it is released( in auto focus mode). At both these instances there is a visible flicker/shake in the frame as well. I do not know if it is a specific defect or a more general design flaw.
Excerpt: The focus is slow, so if it's something you need to absolutely grab the shot, go with another lens. For everyday shooting, in good light, when timing isn't as crucial, it's a nice walk-around lens. That's primarily why I bought it, for when I don't want to drag around all my 2.8 lenses.
Pros: Easily Interchangeable, Good range, Lightweight
Summary: I am using this for my D600. I will give it 3.25 out of 5. It is a good lens for: -Day time shots -A concert stage that has a good lighting system or subject is the focus from the spot light. -Zooming under a good bright light Cons: -It is a bad lens for a serious photography.
Summary: I am a photographer and purchased this lens too use on the Canon EOS 7D. I have had this lens for about 3 years. On the 7D, the further you zoom, the softer the image gets. I had an opportunity too use this lens on the full frame Canon 6D and it was the opposite problem, the more you intensified the...
Summary: I am using it on a Canon 5D full frame camera professionally (weddings). For the price, it isn't a terrible lens and produces acceptable photos when working in low light situations. Pros: cost less than a Canon 28-300 at $2,600.00. Picture quality is not all that bad for indoor wedding photography.
Summary: I bought a used copy of this Tamron lens and the auto focus does A LOT of hunting in good indoor lighting, and only grabbed one good focus shot out of about four. In outdoor day light, the performance was much better. Maybe I should have bought the new thing. I returned this one.
Summary: The long range is not 300mm. It is closer to 190mm. Comparing this lens to a Nikon 55-200 VR lens, I focused closer with the Nikon lens using a Nikon D80 body. Before buying, check to make sure it zooms close enough for you. The focus is slower and more noisy than the Nikon VR 55-200 lens.
Summary: This could have made it to the excellent mark with a little more effort. Seems the ideal all day lens to keep. While I was aware of the slight drop in image quality what was not acceptable was the lens AF function freezing on me. Starts to work again after some time.
