It stated the lens has internal focusing system, but one of the reviewer's photo showed that the lens extends when zoomed. Does the lens extends zoom

The lens does move in and out when zoomed in and out. It using the camera's battery to do this. Different for other brands that has it's own motor, so you need to know the Tamron will work with your brand camera. I have a Nikon D-90 and the Tamron works very well with it. I actually brought the 1.5 x lens separate from it to work in conjunction, and am well satisfied as an amateur photographer

Yes the lens extends zoom. As stated there is a newer version that extends the range and comes with Tamron's version of Image Stablization

The zoom is totally manual...you control it manually. I think your question is: does the lens keep the subject in focus as yous change the zoom focal length? Yes it does.

The lens focuses internally, but the barrel extends for zoom. There is a newer much better version.. 150-600

No. This is not a zoom lens. This is a prime lens with only one focal lenght. No zoom!

The zooming mechanism is internal, responding to a zoom ring located just inboard of the manual focusing ring. The lens remains the same length no matter the value of the zoom.

No because this lens does not have an internal focusing motor this lens needs a camera body with a built in focusing system You could use it as a manual focusing lens though

It does not zoom but does say Nikon (with the same font as the real lens) I was very impressed... bought this for my dad who is a photographer

The focus ring is the small one close to the mount. The large ring controls the Zoom and yes it does extend out.

Are you sure it says that? I've looked over the ad description & I don't see anywhere that it's a zoom lens. The only place I see the word "zoom" was in a customer's question comparing it to their zoom lens. It's definitely not a zoom. It's a single 30mm focal length prime lens that I've enjoyed.

No. It is a fixed lens. However, the zoom level makes it a good everyday lens

No, this lens is like a basic zoom lens, where each value of the focal length corresponds to a certain value of aperture opening.

The lense has auto as well as manual Focus. It has only manual zoom with very limited range as the specification says.

I could not find a way to use it.It did work very well with the non-zoom lens setting.I did have to remove the camera strap when I used this & use a strap on the housing.I hope that this answers your questions, I'm glad that I bought it.

No it does not have IS, but with such a wide lens it is not a problem. The longer the lens the more you need IS.

This lens does not have internal motor for focusing, do your option is manual focus only

I don't remember it saying zoom in the description, but in any case, it is not a zoom lens. There may have been a typo. I would disregard any mention of zoom for this lens. It does not zoom to a different focal length; it stays at 30mm.

The two zooms have image stabilization. The 500mm fixed lens does not. It is also not auto focus. This is a great camera in a great package!

Yes. Zoom and Focus are manual with the inner ring for the later.It s a little bit to freaky not so gradual control.Its endless so no physical connection with lens I guess.
