Summary: Optical Quality = excellent. for the price, having a fixed aperture zoom is great. BUT, the trade off is a slightly plastic feel, a cheap feeling focus ring, and a clunky zoom ring. It is not "a joy to use", but rather, a great replacement for your 3.5 - 5.6 aperture kit lens that came with your camera. You use this because you have to: because you are traveling light, and can't bring your collection of nice, fixed prime lenses.
Summary: When my standard 18-50mm lens broke, I lasted about a year without it, trying to only shoot with my 35mm prime lens. However, when I decided to purchase this, I honestly am so glad I did. This is a great standard lens to upgrade to, even if you have the kit lens provided with Nikon. the f stop is low, which provides quality pictures, and the image stabilization is wonderful.
Summary: Amazing fast lens for the price. this retails for $650 in the US. buying from Japan for $370? worth it. the lens is SO crisp and sharp. holds up against $10k lenses on a RED (on a BMCC 2.4k as a B cam) shooting films.
Summary: I tried to love this lens. I really did. I took many photos in all sorts of different places and settings but they all came out a little blurry. I know it's really comparing apples to a different kind of apple, but the Nikon 50mm f/1.8G blew this tamron lens out of the water in terms of the clarity, sharpness, and every other aspect.
Summary: I love this lense. I'm using it as my primary walk-around on my d5100. The 2.8 factor is amazing, and it has a good range. The autofocus in video is loud, so make sure you switch it to manual when shooting vids.
Summary: Tamron usually makes good, inexpensive lenses, but the build quality on mine was quite poor. The zoom function was stiff from the beginning and never loosened up enough to make it fluid during use. A jerky zoom is not very effective. Consequently I returned it and received a full refund. I was a bit reluctant to try another of the same model so I opted for the 18-35mm F1.8 Sigma, a much better (and more expensive) lens.
Summary: Lens stopped working after 1 year. I contacted Tamron Japan and they refused to provide me warranty service. I contacted Tamron USA and they refused to service as well. Repair would cost about $250. I would not recommend buying from this source. I would highly consider an OEM source. I also emailed the seller and never received a response. I have a nice paper weight now. The error I get is "communication error" likely related to the aperture ring mechanism.
I love it. None of my other Nikkor lenses produce ...

Summary: I am not an expert photographer and there are plenty of other reviews from people more experienced than me, but I just have to give this lens my own personal thumbs up. I bought it because I wanted a zoom with with a larger aperture than my kit lens and I was 'walking too much' to use my 1.8 prime lens for anything but portraits. My camera is a Nikon D5200. This is the only non-Nikkor lens that I own.
Summary: I was hesitant to buy a used lens on line, since I could not see it in advance of the purchase. I am happy to say that 'Condition: Used - Like New' was accurate. I have used the lens for about a month and I ran some tests I found. The lens has performed well. The Amazon site has little box: Will This Work with Your Camera?
