The focus ring has extremely high resistance. Many times higher than the kit lens. Almost Feels as if the motor is fighting against me. Defective?

I felt the same way when I got mine. It definitely has more resistance than the 18-55, but I think it's by design. With a more shallow depth of field at f1.2 you want a tighter focus ring for better control. Whether yours is abnormally resistant I don't know.

I don't have the kit lens, however, mine is very smooth SO I would say most probably yes.

I'm guessing it's the lens, since the motor is built-in and not in the camera. Easiest way to find out is for her to stop by a camera store and try a different lens on it.

Yes it is, the focus ring looks like it doesn't move. It does. Remember it's LED, hard to see in bright sunlight. WB

I assume you've tried auto focus at different legnths. If unsuccessful you definitely need to return the lens. Sorry to hear about your troubles.

Mine arrived with a black spot right in the middle of the lens at the higher power. Makes spotting even a large car tricky at distance. LOL I will attempt to return it for a working one. Lot of trouble. You get what you pay for .....and sometimes even less.

I'm almost sure youre lens is good. As it is a prime lens, you cant control the f-stop with the camera body, so the the camera can't detect that there is a lens attached as it would with your kit lens. Go into your camera's menu, go to the section designated by the picture of the gear. Scroll down until you see the option that says "Release w/o lens" and enable it. You should be able to use the lens now.Hope this helps!-Andrew

It's an autofocus lens. There is an outer ring that pushed in one direction will be manual focus only. Either pull the ring closer or push farther away and you should get autofocus.

Twist the lens. It may be that it is indeed too low to get a good focus. If you twist the lens on mine, it comes into focus.

No your item is not defective. This particular extension tube doesn't allow any data to transfer between the lens and the camera thus, not letting the camera know to focus or to change the iso.

That's strange I don't find mine to be extremely noisy at all. The loudest lens I've ever had was a 50mm 1.8 which was crazy loud!! The Tokina makes a little sound when focusing, nothing to go crazy over....

This seems odd. I've not thought that before of this lens. I shot part of a wedding ceremony with this lens. You are referring to the vr or the focus motor? Do you have any other lenses with VR? How does it compare?

Theres a ring that comes off. Its been a while since ive used mine but you may need to screw on ring to lens first then add the lens adapter. Or try with out the ring? Also it only fitd on my kit lens. Check thread size

I have to return my lens. Used twice on a shoot and serious focusing issues both times. I will not pass judgment, as I plan to return to Tamron under their warranty and I bought this upon recommendation from fellow fans of this particular lens. I shoot Canon and this was the first time I purchased outside of their line...

I have the same camera. It's perfectly normal. It's just the camera focusing.

No thats not normal. But make sure the focus ring is in the right position. Push it forward for autofocus, pull it back (toward the camera) for manual focus.

Is the camera constantly trying to focus? The only motor I can think of is the one that moves the lens. Try it standing in a stationary position filming or photographing something that is not moving - like a tree trunk. If you don't hear any sound because the lens doesn't have to move to refocus, then I would guess it is the lens motor. I didn't like this camera personally and ended up returning it.

On my camera, I have to set the focal length and enable the exposure ring function when using this lens. Once complete, everything is automated but the focus.
