<p>I am not sure if this will help or not, but will try to share my experience on decision of 70-300mm lens. I was debating the same for couple of weeks, which one to buy? I read most of the reviews/comments available on Sigma and Tamron 70-300mm and found ppl who bought Sigma they were happy with it and ppl who bought Tamron they were happy with that.</p>

<p>Advantage of Tamron is sharpness, contrast color etc... and autofocus is slow (I have used Tamron 18-200mm earlier and I liked the color, sharpness) whereas Sigma's autofocus is fast and colors are little soft (this is my understanding and my opinion) ... after much debate with myself I spent more money and bought Nikon 70-300mm VR and it's been few days and happy with it.</p>

<p>To add on it... at 300mm focal length on crop body shutter speed should be faster then 1/500, so in low light it will be difficult without tripod/monopod. I was able to take pictures at 1/8s @ 70mm and 1/13s @ 300mm non-moving objects using 70-300mm VR and came out really nice.</p>

<p>I hope this helps.</p>

<p>You may want to check to see if the Tamron has the built-in motor for Nikon AF-S required D60. I don' think the Tamron has that feature. On the Sigma, only the latest has AF-S feature so you still have to make sure in case the store has old stock. Without the in lens motor (AF-S), there is no auto focus.</p>

<p>Tamron and Sigma does have 70-300mm lens with a built-in-motor.</p>

<p>Was wondering if anyone knows anything about the Tamron AF 18-200mm 3.5-6.3 XR Di II? I have a Nikon D50 & am looking at different lenses for wildlife photography. Any help would be greatly appreciated.</p>
