The Tamron SP AF 17-50mm F/2.8 XR Di II LD Aspherical (IF) is a good value fast standard zoom lens for APS-C cameras, offering a constant aperture of F2.8 and covering an effective focal length range of 26-75mm. Optical construction comprises 16 elements in 13 groups, and at its minimum focus distance the 17-50mm gives a maximum reproduction ratio of 1:4.5 - not 'true' macro, but usefully close nonetheless. Tamron also makes a newer image-stabilised version of this lens for Canon and Nikon cameras.

Excellent Bang for Buck
When I bought this lense, I was still considering buying other lenses to compliment it, but soon realised that short of buying exotic primes or ultra-wide angle lenses, this lense covered almost all my photography needs.It is a very good alternative to the 17-55 lenses in Nikon and Canon's repertoire at about a third of the price, and it produces stunning results for the price. It's very sharp across the frame when stopped down to about f/5.6 but even at f2.8 it produces very sharp images in ...
I say this is the sharpest zoom, and probably the sharpest LENS I have ever tested, at least when at f4 or lower. Contrast and bokeh are nice too, even at 2.8, it fits perfect with K-5, autofocus works fine and quite fast and, yes, it's noisy, but no one died so far because of this. One more thing...it costs about 40% of Sigma 17-50mm, f/2.8 Problems: Plastic body looks cheap...
Tamron SP AF 17-50mm F/2.8 XR Di II LD Aspherical (IF)
This is a solid performer with good contrast and color rendition, resolution is impressive wide open and by f4 is outstanding. Focus speed and noise are more than acceptable. The most impressive characteristic I noticed straight away, is the superb control of flare, or almost totally absent at wider apertures when shooting into the sun. This is quite exceptional compared to any lenses I have used and very desirable for landscape work. Problems: I don't know if it is just my copy, but I have ...
Great Optically FF at apertures F5.6 or above at under 3 mtrs
Great Optically Problems: Quirky AF problem under 3 mtrs at F5.6 or above

I have a tamron 17-50 and the Nikon D7100. I know that the D7100 is fully weather resistant, more than the D800, but will that pair hold on extreme weather? I'm not sure how durable is the 17-50, so will heavy rain or snow ruin it?
I'm not familiar w/ Nikon, but even assuming bother body and lens are weather sealed, they aren't for taking pictures in extreme weather/strom or even rain. The fully rugged body like D4 or 1D series pn Canon are ment to take more extreme temperature, still not rain. At a minimum I would get a rain cover, they are expensive usually less than $100. Even plastic bag will protect your gear better than shooting unprotected in the rain. Generally when the manufacturor said weatherproof it just mean it will take some sprinkling. If you felt that you have to take cover yourself that is pretty much mean your gear need extra protection also. Continue Reading
As far as I know, the Tammy is not weather sealed.... so it does not matter a whole lot if the d7100 is. Continue Reading
Sony 16-50 f/2.8 vs Tamron 17-50 f/2.8 for A77
Actually i have the Tamron 17-50, and it works beautifuly, it's almost all the time on my A77. But in my country, the Sony 16-50 is selling for $500 new, and i can sell my tamron in $380; so for only $120 i can "Upgrade" to the Sony. I like the weather sealing and SSM of the Sony, also the 16mm vs 17mm it's welcome, because i use my tamron mostly for astro, landscapes and social photos (Here are my photos with the Tamron https://www.flickr.com/photos/biovipah/sets/72157642161320685/ ) Do you think it's a worth upgrade? The 16mm f/2.8 is critical for me, it's sharper than the Tamron? Thanks!!
. Go for it ! Good opportunity to get the 1650. A77 has built in correction profiles for this lens. 1650 f2.8 is my workhorse. I'm so thankful for this lens ! . Continue Reading
Do it, I did and have not used the tamron since. Continue Reading
I had both when I bought the A77 and 16-50mm kit and tested them. There was really nothing in it between them. At all focal lengths I doubt you'll see much centre sharpness improvement over the 17-50mm, perhaps a little at 50mm, but tiny amount. You might get better corners on the 16-50mm though. In pure sharpness terms the 16-50mm is not worth the difference, the 17-50mm is a VERY good lens. What you'll gain is the SSM for almost silent AF operation and weather sealing and it is those that I swapped to the 16-50mm for. If you are hoping to see an improvement in sharpness, I believe you will be disappointed. Continue Reading
[UK/EU] Interest Check: K-5 + 2x Tamron Lenses
Ahoy! I have a very nice set of items which includes a boxed (like new) K-5 body with low actuations, Tamron SP AF 17-35mm F/2.8-4 Di LD (IF) Aspherical (unboxed with caps hood) and a Tamron SP AF 17-50mm F/2.8 Di-II XR LD (IF) Aspherical (boxed/immaculate). I'm thinking of listing as a bundle, but possibly as separates (I haven't decided yet). Anyone in the UK/EU interested in these items as I'll either list them in the DPR classifieds or other private classifieds/evilBay/Amazon. I'm running both A and K-Mounts, but glass for the A-Mount is substantially cheaper like-for-like compared to K-Mount. Anyway, if nothing else, it's just some heads-up.
