Showing 1-10 of 21

Conclusion: I am disappointed with this lens and would NOT recommend it to anyone. I'm a semi-pro shooter using this lens on a Pentax K20D. I get great results from all my lenses but this one. I have calibrated front/back focus as well as possible and am still disappointed in the sharpness.
Pros: price, versatility
Cons: soft, slow AF, chromatic abberation at long FLs
Conclusion: I bought this after owning a Tamron 28-200 LD years ago...partly on the basis of a couple of reviews.I was disappointed in it.The AF was not very good(main problem).In decent light it was adequate.In anything approaching low light,it hunted a LOT.
Summary: I am happy to get a versatile lens by a good company at a decent price. For some reason, some shots come back overexposed and I can see no reason why. I can use the same settings and take the picture again and it will correctly expose the shot.
18-250 seems like a 18-190mm compared to nikor 55-200mm??? (Need to focus on Infinity)

Summary: I got this lense and it zooms wide and out pretty far, but when I compared it to my nikor 55-200mm lens it seemed like it was only zooming into 190mm not 250mm. I was told that I had to zoom in on infinity an object the farthest away. I am not a professional but this seemed weird to me.
Summary: I just purchased a Nikon D5100 camera to use with the Tamron 18-250mm lens. To my surprise, the lens doesn't focus when you switch the camera to Live View. I tried the Nikon lens that comes with the camera and another Nikon lens and both autofocus in Live View.
Summary: I own several Canon lenses but they all lack the range of the Tamron 18mm - 250mm. I like the picture quality as well as the versatile range but I find the lens flimsy when compared to my Canon lenses.
Conclusion: In sunny climates you may be able to use this lens on full zoom with only an ISO fo 500. However, in the UK in our dismal gray cloudy summers, you need approx 640 to 1000 ISO just to stop the shaking. I posted a review on our disapointement with the noise levels on the Canon 40D.
Pros: crisp for non L lens, good colours
Cons: zoom range to long, at 250 you need a large ISO that only then creates noise
Summary: I have just purchased and returned this as it is not fully compatible with the Nikon D40 which I own. It will only focus using the manual focus and therefore is very limited in it's use. If you own a D40 you need to purchase a lens with a built in motor to enable the autofocus to work properly.
