Hey guys!

I sold my good old tammy 17-35 6 months ago and I do have enough money now to get a better replacement. As a general walk around lense, which one would you recommend the most? I haven't had a prime in ages and I do miss it a lot.

I personally don't think the Tamron 17-50 is a very good lens, especially for the money. Otoh, the Sigma (and the Canon 28mm f/1.8) are both very good lenses. I prefer the 28, but either will serve you well.

As a walk around I prefer the Tamron 17-50 2.8 - it's very good for the money

But I suppose it depends on where you walk !

17-50. Very sharp, even wide open. Very highly regarded. Better range when "walking around".

Why do u think the tamron 17-50mm f2.8 not worth $420 brand new ?
IMO it's a cheap lens, very good optic and constant f2.8.

sold my kit lens, got a tamron 17-50 about a month ago, love it.

just ordered the sigma 30mm

:D

you'll probably end up getting both. i'd start with tamron though, more versatile with zoom.

plus if you start with a prime, you aren't going to be impressed with results from zoom. They will inherently be not as cool.

So it seems like versatile and not as crazy DOF, then moving up to one focal length and crazy DOF seems like a good one.

IMO it's a cheap lens, very good optic and constant f2.8.

For me it's all about the AF. Yes it is a decent optic and a constant f/2.8, but the AF is so loud and relatively slow compared even to the Sigma 18-50 dc Macro (which is no speed demon itself). I gave up on mine after 9 months of using it as my main lens. For candids on the street, it was too noisy and slow; so much so, that it was tipping people off before I could get the shot. For model shoots it was no good. For one shoot in particular, the AF was hunting in a well lit room (!) and the model was tensing up every time I'd go to take a shot. She commented that she could "feel the shot coming". The breaking point for me was when it started hunting in a moderately well lit news conference (sigh) and the AF motor made so much noise that the Mayor stopped his speech and looked at me. At that point the lens was sold in my mind, which was quickly reinforced when the mayor, after his speech, commented that I might want to look into a quieter lens.

Imo, the Tamron 17-50 is no better than the 50mm f/1.8 II, but it's 4x the cost.

So the only complaint is the noisy focus as many are. But still it's a cheap lens comparing to the Sigma 17-50mm ($670), canon 17-55mm is ridiculously expensive ($1,100). you pay for what you get. For general walk around, it's good enough.
the 17-50 and the 50mm r in different category IMO.

The term "good enough" is subjective. :) For me it wasn't good enough to be anything but a $400 paper weight.

And by the way, I'm not complaining - you (and the OP) asked for my opinion. :)

BTW, are you aware that for only an extra $250 you get HSM and 4-stop OS with the Sigma 17-50? Now THAT'S a deal.

right, the Tamron is crazy sharp and the AF is good for me!

I agree. Most lenses out there even the 18-50 kit zoom has really good optics. In the end, it is AF speed and accuracy that determine whether you get 90% good shots, or just 50%.

I have both, I got the 17-50 f2.8 first and loved it. I picked up the sigma 30 and I'm not sure I have used the Tamron since. I could never imagine how the old film cameras could by with just a 50mm but the sigma 30 is like a 50 on a crop camera. It is so usable as a walk around lens so fast so sharp and a great bokeh. If you don't need the wide end I would say sigma is the way to go. You can hand hold in just about any light at iso 800.

just bought my Tamron 17-50 a month ago, and getting the Sigma 30 in a few days.

I hope I still find uses for the Tamron, it's a great lens! If not, to the market place it goes.

I think I will though. There will be times zoom will be more important than crazy DOF.

To me the Tamron 17-50 and it's cousin the 28-75 are two of the best lens you can buy for the money, I've had both and still have the 17-50 as my walk-around-do-it-all lens and my main lens for portrait work, sharp as it can be.

I had the sigma 30 for two years. Just sold it a couple of days ago since I've had the 5D for half year and the 30 didn't get much use. Guess what? I already miss it. The sigma 50 does work great on 5D, BUT there is one thing I don't like. For head shot, in order to get enough depth , I have to shoot at f/2.2 or smaller, f/1.4 often turns out too shallow for my taste. Under low light, the f/2.2 often feels not fast enough and now I'm missing the 30! :-(

I guess I'll wait until 5D III come out then upgrade to it. Then f/2.2 won't be an issue with better high ISO on 5D III compared to 5D. I'm expecting at least two stop better performance since 5D II is already more than one stop better than 5D.
