Tamron 17-50mm VC vs non-VC please take a look

Hello everybody!

I am relatively new to photography but it is something I am becoming more and more passionate about. I will be travelling to Vietnam for 3 months soon and I decided to buy the Pentax K-5 as my first DSLR camera.

I am looking for a practical lens that I will not have to change around, a step up from kit lens but also something that is affordable and has good "bang for its buck".

I find myself drawn to the Sigma 17-50mm or the Tamron 17-50mm but I am more attracted to the Tamron and this seems to be the choice for me. In terms of value its significantly cheaper and seems to deliver what I need.

What I need help with, if you could help me - is understanding the comparison between the non-VC and the VC version of the Tamron 17-50mm.

My understanding is that the VC can be useful but you will have to sacrifice some sharpness compared to the non VC version. Anybody got experience comparing these two? What are your thoughts on making this decision? If I have decided on this Tamron lens which is the one to go for and what are your reasons?

I would really appreciate your help on this one.

I would prefer to have WR for travel. Imagine things could be humid in Vietnam.

What patajac says is worth considering if you can stretch that extra bit.
In which case... you wouldnt be dissapointed with the pentax 17-70 F4.
Also as JinDeso points out I think you will find the tamron VC is not available in pentax since the K5 has Shake Reduction built into the body.
Other than that I would opt for the Tamron 17-50 or tamron 24-70.
There are two bennafits here though... firstly the none VC version is cheaper,
and secondly, the none VC version slightly outperforms the VC version.

According to Tamron, it is not available for Pentax.

Get the non-VC version. It is not only reported to outperform the VC one at f2.8, you don't need the VC at this focal length as the internal SR is very effective in the Pentax. I have the non-VC one for my K20D, and I love it.

Good advice since, as was pointed out, the VC version is not available in Pentax mount.

Seems to me that the da 18-135mm would be a better choice. very nice lens and WR.

I doubt the 18-135 compares in IQ with the 17-50s, considering the 17-50s has been stated to be "as good as primes in the range".

The 18-135 is a nice lens in a separate context though.

The build quality of the Tamron is a bit poor.
The zoom ring on mine even failed.
