I bought this lens a few days ago. It seems good built, pictures are good quality and sharpness. I don`t like zoom ring, it`s little stiff (at least for me). When you turn on VC, you can really hear it. I have made abot 200 fotos; AF is working good.

good picture quality; good sharpness

zoom ring a bit stiff; you can hear VC

I bought this lens used from someone on here. He mentioned the dial was stiff and it is. It's not so bad but I have to get used to gripping it instead of just zooming with one finger. I don't know if that is normal for a new one or not.

I have a canon eod-1000 and this is the second tamron lens i'm buying to this camera. I'm happy with the buying the tamron lenses are good. If you can afford to yourself to buy an original lens of canon it's better. But as a tamron product it's A very good lens.

The Tamron AF 17-50mm f 2.8 XR Di II is a lens designed specifically for digital SLRs and their smal

Moderate pricing for a fast lens.

Loose manual focus ring

I have to say this is a very impressive lens for the price. It has allowed me to get some great shots of my toddler who never sits still. I can hand hold this at about 1/40th a second if I'm careful to stay still. Sharpness is great threw out the whole range.

VC Focus Speed Aperture

none

Yes, I would recommend this to a friend

Consistent Output; Strong Construction

Heavy; Loud

I wanted to provide some detail about my experiences with this new lens, and it's performance in my day to day photography work. If you had asked me 15 years ago, I would have been very hard pressed to recommend a Tamron Lens, but with some work and time, they have managed to sell me on this...

Solid Construction: OK, we hear a lot about "plastic" feel and less than rugged construction; I think we will have to get used to this construction method as it will be the norm going forward.

Auto Focus Lock: OK here is where I will complain about Tamron's way of doing things; On other AF lenses that I have from Nikon, you can turn the Auto-Focus Ring, while the lens is set to Auto and it freely turns without causing any potential damage to the lens.

Finally, a fast, stable lens at an affordable price.

Consistent Output; Durable; Easily Interchangeable; Quick Focus; Sharp Focus; Strong Construction

My first lens upgrade from the kit one I got for my Nikon. I really like it, its strong, works well and big improvement in the pictures. No complaints from me at all.

Durable; Rugged

After a couple of months I started having issues with this lense. It would not focuss. Sometimes i have to press the shooting button several times before i can take the picture. I am very unhappy with this lense. I recomend you not to buy it. Moreover. Dust comes into the lense.
