"Pese a su bajo precio, tiene muy buena calidad de imagen y es muy liviano, para alguien que quiere un objetivo económico, con buen alcance o quiere iniciarse en el mundo del macro, esta es la mejor opción. Ademas es compatible con la D40 y similares, que no traen motor de enfoque en el cuerpo. "

    "This lens is great for the price. Are you getting a Nikon 70-300 VR for this kind of money? No. What you are getting is a lens that is sharp, contrasty, has a good macro mode on it, and costs $130 bux at the time I am posting this... one that will work with your D40/D40x/D60\'s focusing system. Is it optically perfect? No. It has some CA, it is not very fast... but good heavens it is sharp, light and well made. Buy it. "

    "Granted, you get what you pay for - I think this lens does it\'s job. For folks on a budget who want to shoot like the pros, this lens is great. I shoot macro shots in my own yard. Good for wildlife too. You might still need a tripod for some of those tricky shots though. And as always - read the instructions! "

    "This is a high quality lens at an affordable price. Shipping was fast and priced fairely "

    "From 70-200mm, my sample of the Tamron 70-300mm Di zoom lens is markedly sharper than a Nikon 55-200mm VR lens that I owned and then sold, based on comparisons done with a 10 MP Nikon D60 DSLR camera. Indeed, from 70-200mm, the Tamron lens is quite sharp, period. It\'s clearly softer at 300mm, based on images viewed at 100% magnification on a 24\" computer monitor, but when viewed at 50% magnification (closer to relative default print size), 300mm images look fantastic. More importantly, at 300mm it produces images that print with excellent resolution at 11x16\". CAs are the one clear weak point for the Tamron lens but they are easily corrected via basic post-processing of RAW images (maybe JPEGs too?). AF speed is similar to the Nikon 55-200 VR AF-S lens and VERY accurate in good lighting. At around $140, this lens is a remarkable value and worthy of a 5-star Amazon rating, though I\'d give it 4.5 stars if that option were available. "
