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.

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

A-Mount Tamron 17-50 or Sigma 17-70, which 1 is a good deal for my A58?
I need a replacement of kit lens for my A58 and I found Tamron A16 SP AF 17-50 mm F/2.8 Di II LD Aspherical (IF) which is not " XR " at around $375, where as Sigma 17-70 is around $500 and might not available in my country, I may have to pay 20 to 50 bucks extra for shipping, total $550. (1) Which one is a better deal? (2) Also what is the difference between XR and non XR tamrom lenses? I know they use VC for image stabilization.
The Tamron is a very good lens and is a fixed f2.8 at all focal lengths. It is pretty sharp and balanced perfectly on my A65 and should be the same on your A58. I believe "XR" refers to "ED" glass or something similar to that. The focus on the Tamron is slower than the Sigma and a little more noisier. This might be an issue for videos. Also, the Sigma has a slightly longer range and could be more suitable for you. I was able to get good portraits with the Tamron at 70/f2.8.

I just found :- XR - extra refractive index on tamron I am looking for:- (1) Great Image Quality (2) Wide Aperture (only 2.8 is in my budget) (3) Replacement for my kit lens I don't care for A/F noise or speed, but need AF Regards Continue Reading
I could not be happier with my Sigma 17-70 "c" The old version was pretty good. But they have really improved the lens this time. Aand I like the clean look and compact size.. I would compare the bench tests.. on both http://slrgear.com/reviews/showproduct.php/product/1297/cat/23 http://slrgear.com/reviews/showproduct.php/product/1560/cat/31 The Sigma seems to be consistent and sharp across the range even wide open. No Crazy corners where at one range the corners go to pot... DPR hits if for soft edges that don't sharpen up with Fstop increases at 17mm But its soft edges are better than a lot of lenses improved edges.. I wrote my review of the lens after a couple of days here is my thoughts related to Sony use and a link to the DPR USER review I did for the lens in general. http://www.dpreview.com/forums/post/52277816 Continue Reading
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 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
photo tint problem with tamron lens
Hi, I own a 60D and use a tamron 17-50mm f2.8. For some reason, when I take pictures of people indoors, they have a yellow tint to them. This does not happen with my 50mm f1.8, so I was wondering if anyone else had this problem and if they know how to fix it Thanks
Does your problem happen with the same scene but different lenses, or did you notice the problem at different locations? You can correct for this by doing a manual white balance. Not only this will correct for the color of the light, it also will correct for any color imparted by the lens. Continue Reading
it happens only with this lens and at a lot of indoor scenes. I tried changing the color temperature manually to correct for white balance, but its difficult to remove the tint. I do not know how to accurately adjust the magenta green on the camera, so I left that alone. Continue Reading
