Some amazing pics in this thread!

I hadn't really looked at a replacement for my 18-55 IS, was instead going to add a prime around 30mm to my kit. But this lens is now on my radar.

So is this lens tack sharp wide open? Are there any issues with QC with this lens?

This may sound like a silly question - but when you add extension tubes, does the lens remain the same 17-55 range? Like could you take those macro shots, and then pull back and take a 17mm shot as you normally would do?

In other words, if I added some tubes to a 50mm prime - would it remain 50mm? And only increasing the focal range? And could the lens still be used the same as a portrait lens with the tubes mounted?

Or do you lose some of the focal range?

I'm confusing myself here, but I can't get my head around the science of adding tubes.

Wondering if I should toss my nifty 50 for a macro lens, or just get some extension tubes instead!

I'm not 100% sure, but I think you lose infinity focus by adding tubes.

Oh right, you would have to lose something in the distance, that makes sense.

In the one week I've had them it seems like you actually lose a lot of focal range. I don't have a number, but the range, from MFD to maximum distance, becomes pretty small. That may be because I have been using multiple tubes.

As far as this lens I highly recommend it. The main negative that you will hear is the sound it makes when focusing. The focus motor does make a buzzing noise, but it doesn't bother me. This lens is sharp wide open at all focal lengths. It provides great color and contrast. I have no complaints with it.

So if I think my 17-50 isn't focusing properly - whats the SOP? Take it to local shop (didnt buy from there) or call Tamron direct? I bought it used FYI.....

Any tips on what to do?

I just sent mine into tamron. You should try doing the same. Obviously, they're best qualified to work on their own lenses.
