Makes sense.  Nice that Roger did that testing.

Good luck with your lens!

Thanks. I should have it back next week.

Just because some other person had a bad experience (which they may or may not have exaggerated) doesn't mean that you will.

I am sorry to be the devil's advocate here but this can be reversed:  Just because some other person had a good experience (which they may or may not have exaggerated) doesn't mean that you will.

Sorry I cannot consider it an unbiased argument.

More technically: This may cry QC issues and as neuro said not complete reverse engineering but the end result unfortunately remains the same for the unsatisfied buyer.

 I recognize the price difference and the IS advantage of course but it seems unfortunately that there will be some disadvantages together with the advantages.

Just out of curiosity - did you actually have a dialogue with Tamron about the lens?  I'm curious if they acknowledged your experience as a wider spread problem.  Secondly, do you know your original serial number?  I'm interested to know if they fix your lens (probably with an updated circuit board) or replace it.

I did call and I spoke with someone in their service department. He did not offer that type of information but neither did I specifically request it. He did seem confident that the issue could be resolved with repair or replacement.

The lens serial # is 038xxx. I can provide the exact serial number to you privately if you wish.

Jim, I don't need the serial number, but I'm glad you know it so you can tell if you get your lens back or a replacement.


Follow up:

Today was either day #4 or #5 depending on whether you count the day that the lens arrived to Tamron at 10:20 AM. Either way it was beyond their "three day turnaround" policy on warranty repairs. I had heard nothing despite sending a contact email via http://cgi.tamron.com/repair_status_form.htm two days ago. I called and spoke with someone who seemed to be a secretary in the service department. She looked up the repair order and put me on hold in order to speak with a repair technician. She came back and told me that a new board was required and it was not in stock, that they were waiting for it to be shipped from Japan. She tried to reassure me that the turnaround would be quick once the board arrived, although she had no idea when that might be. I explained that I was not satisfied and asked to speak with a manager. After about ten minutes on hold I spoke with a supervisor. I explained to him that the current state of affairs was unacceptable and that if they could not repair a brand new lens in their guaranteed turnaround time, they should replace it. I also mentioned that it would have been good service to have initiated contact with me since they had my email address and my mobile phone number. He basically agreed and said he would speak with his manager.

He called back an hour later and said they were going to overnight a brand new lens to me that was being pulled from their stock.

On the whole I'm not really happy having had to chase them down on this.

I will post further when the new lens arrives.

I finally had the chance to use the first stabilized 24-70/2,8 in the history of mankind.
Unfortunately, being the focus ring at the bottom of the lens, using it on a rig with a follow focus, as I suspected, is not comfortable at all and that's already a "no go", for me. Anyway, I considered to keep the lens anyway, even if it could not replace the Canon 24-70/2.8, for times when I have to act fast and use the camera on a monopod or even handheld. But... VC doesn't work, at least on my sample, as well as it should.
I noticed it shooting stills, but this makes me suspicious about its video skills too.
What I noticed is that it takes a while for the VC to start working after you half press the shutter button, so it is not very helpful if you have to to take a picture "on the fly", like during an event.
What's more, with faster shutter speeds (let's say over 1/60) if I leave the VC enabled I get less sharp images than if I keep it disabled, so I always have to check the shutter speed I'm using to decide whether to live the VC enabled or not. Way too annoying.
After a couple of days of testing, I brought the lens back to the shop. They told me than in a week they'll give me another copy to verify if this issues are to be considered "normal", but I think I already made up my mind.
As far as the optics is concerned, that's definitely a very good lens, considering its price, but the mechanical side leaves a lot to be desired, as often happens with third-party lenses. And I'm also afraid, from what I read in many posts, that QC is quite an issue at Tamron's. I don't wanna have to test 3-4 lenses before getting a decent one and keep worrying that it could suddenly stop working properly...
Anyway, I will check this second sample before deciding.

I finally have my thoughts to chime in.
I like this lens, though have to say I won't be using it for probably 70% of my work. Why?
I shoot lots of gigs. Often the light is bad at best,  but when I broke out my tamron 24-70 VC I found it could not focus in poor light. It was probably -1EV, but even with the AF assist lamp it was returning drastically OOF images, while acknowledging accurate focus.

The 50 1.4, 85 1.8, sigma 35 1.4 and the Canon 24-70 2.8 I&II all focused like champions in the same conditions even in servo with no assistance

So, in a bizzare turn of events, I find myself unable to use a standard lens designed for low light work in a low light environment. I guess I'll be using it for weddings, portrait shoots etc, but it'll be staying in the gear cupboard for gigs. Which is a shame, really....

All image stabilisation (including that on Canon lenses) works in this fashion. So if you don't like its behaviour then IS/VC lenses are not for you regardless of who makes them.

That's bizarre and I've never heard of anything like that except with tripods where you need to turn off IS with longer shutter speeds as IS/VC keeps moving the lens when it isn't required.

If what you are saying is true, I would return/exchange the lens.  I have no such issue and after AFMA have consistent focus results on all of my bodies with the Tamron.  It shouldn't perform any differently in low light than the other lenses save perhaps the Canon 24-70II.  I get much more accurate and consistent results from the Tamron than I do from my own copy of the 85mm f/1.8 (which is actually my most inaccurate focusing lens even after careful/multiple AFMA).  It's not terrible, but I have very high sharpness/accuracy expectations for all of my kit.

Obviously, all lenses stabilizers need a bit of time to star working, but the VC of the lens I tried took way too long.

What's more, with faster shutter speeds (let's say over 1/60) if I leave the VC enabled I get less sharp images than if I keep it disabled, so I always have to check the shutter speed I'm using to decide whether to live the VC enabled or not. Way too annoying.

That's bizarre and I've never heard of anything like that except with tripods where you need to turn off IS with longer shutter speeds as IS/VC keeps moving the lens when it isn't required.

That's the other reason why I guess VC has something wrong in that sample.

Anyway, they already gave me another sample, I hope I'll be able to run some tests in the next few days. I'll post here my considerations about it. I really want this lens to be up to my expectations, a good 24-70/2.8 with image stabilization would be extremely useful, for me...

I just did a tour to Israel and Rome, and ended up using the Tamron for about 75% of the shots.  I brought home great results despite dealing with often less than ideal lighting conditions:  Here's a few samples:

1/15th second @ 70mm = no hesitation.  Just part of the reason why the Tamron is just a great travel lens.  And that bokeh ain't bad, either :)
