Traveling 17-70mm vs 24-70mm vs 24-75mm

Heading over to europe for 6 weeks and looking to travel light, so im only taking 2 lenses. I guess its a good excuse to buy another lense, but time is getting short and the more reviews I read, the more indecisive I get. In short, I need to buy a lense this week and I cant make up my mind

Im taking the sigma 10-20 and want something a little longer to take along with me rather than the primes ive got, so im looking at;

Sigma 17-70 f/2.8-4.5 DC macro
Sigma 24-70 f/2.8 EX DG (is the new IF worth the extra money?)
Tamron 24-75 f/2.8 XR Di

I could probably stretch the budget to $1000 AUD if there is something worth looking at that I havent thought of. I was originally looking at a super zoom for travel, but it would probably spend most of the time at the wider end anyway, hence looking at the above lenses.

Any help would be appreciated.

It's my understanding the Sigma 17-70 has been discontinued, though new copies could still be available as well as used. It's been replaced by the 17-70 f/2.8-4.0 OS HSM. It's a nice lens. Heavy, though.

I think the Tamron you mentioned is the 28-75 XR Di LD IF lens (same one I have). It starts at 28mm, not at 24, so it really is not a wideangle lens. You have the 10-20, but would have nothing in the 20-28 range.

I highly recommend the Sigma 24-70 IF DG EX HSM. But make sure its the HSM version with the 82mm filter size. I have some photos on here that show it does. It's sharp right from F2.8. Many people prefer the Tamron but I think that the 4mm on the wide end is more useful than the 5mm on the telephoto end.

If you are using in the daytime or bright light environment, a 18-200 will do the job.

In terms of exposure, you are correct. However, you will miss the chance of getting a shallower DOF as offered by faster glass. Also, superzoom lenses are always optically worse than their specialized counterparts. In the end it's all a tradeoff; how much quality do you want to sacrifice for convenience?

Ouch! That's a seriously heavy lens! Over 700 grams! I agree 4mm wide is better than 5mm tele, but the shier weight of this thing will not help TS to "travel light".

Anyway, I'd go with the Pentax 17-70 f/4. Just bought one and absolutely love it. Pretty fast at 70mm, sharper than the Sigma 17-70, not too heavy, and a nice range.

Consider the Sigma 24-60mm f/2.8 EX. Can be had for a bargain.

Small for a f/2.8 zoom, but extending barrel and no HSM. Quite fast AF though. 77mm filter.

I also highly recommend the Pentax DA17-70 for "one lens" situations as well. In fact, you would not miss a whole lot if that were the only lens you took.

That being said, I just came back from Europe, and used mostly DA Ltd primes. I very seldom needed more than 70mm, but when I did, I used the compact DA50-200.
