Tamron 17-50 f2.8 VC

Using this lens on a 550D. Fantastic lens. Not as sharp as the non-VC version, but for video it exceeds resolution capabilities of the video anyway. It's also heavier and bigger than the non-VC.

BUT who cares! VC (vibration compensation) works an absolute charm. It takes away all of the shake. An easy test would be to use the extender/digital zoom button and switch VC on and off. Huge difference. With this lens there's no need for any brace or stabilising system. I also use the camera strap around my neck for added stability.

NEGATIVE: the focus ring is not smooth. On the wide end it is okay, but zoom in and it's behaviour becomes finicky. It doesn't stop and start smoothly and the images looks as if the focus is clicking and jumping around. Solution? Follow focus? I'm hoping that the added gears and friction will smooth out the motion.

Can anyone recommend a follow focus system that is priced right and works excellently? I'm hoping that the follow focusing system doesn't get in the way of the focus ring however!! Can it be more forward or underneath a little?

Cheers,
Frank

Can you describe "finicky"? Does it just get tighter when zoomed in?

Good to hear another good review on the Tamron. I've been thinking about getting this for a while.

I love the Tamron 17-50mm f/2.8 VC. Been shooting a bunch on it with my T2i. Here's a little snippet from a short I was helping my friend film the other night - needed the 60fps of my T2i and a wide fast lens:


(Shot wide open at 17mm f/2.8 and 800 ISO with shutter speed at 60 on a glidecam.)

Anyone recommend a follow focus that gives you space to access the zoom ring?

I am ambivalent about this lens. For the outdoor scenes its about the same as the kit lens 18-55 IS. For low light, its just hair brighter than the kit at f3.5, and at the long end (50mm) its much dimmer than a 50mm f1.8. Obviously, if you have to have 35mm f2.8 for indoor situations this may be it. But that's an expensive solution to a rare situation.

interesting solution to saving money. seems inconvenient to me. it seems your solution is to lose a stop or so on the wide end...lose more on the mid end and then swap lenses on the long end.

oh well. each to their own. for mine, i like the fact that with one lens i can go from 17-50 at 2.8 all the way with one lens. one that has an awesome steady function. i also have a 1.4 Nikon (with adapter) that can get me that low light stuff - no VC but!!

I agree that for indoor 17-50 f2.8 definately has advantages.
Just IMHO, I would rather get Canon 50mm f1.8 and Sigma 20mm f1.8 for the same amount of money as Tamron 17-50 f2.8. I am partial to prime lens though. I think these fast primes make indoor work much easier and the results look better too.

Im new in photography / videography and I was searching very long for canon 18-55mm kit lenses replacment. I wanted universal zoom lenses with f/2.8, but canon 17-55 f/2.8 was to expencive for me at that moment, thats why after long reviews reading I decided to try tamron. It was way much better when my canon kit lenses in photography and videography. Only one thing I dont like in them - AF.

I read somewhere, that If you turn off VC the fotos will sharp as in older version, but I have no idea how much that is true, cose I never had before old version of this lenses without VC.

By the way, there is already thread about this lenses in second page: "Thoughts on Tamron 17-50mm f/2.8 Lens?"
