How to differentiate Tamron 17-50mm with and without motor ?

[dimashp]

Dear all,

Does anyone know how to differentiate those two just from physical built only ?

I heard that with motor is Di II, and without is Di. Then some says with motor has AF switch. Then about the code. Then later about the connection pin, 8 for with motor, 4 without.

Confused Hehehehehehehe...Anyway, does this apply to Canon mount as well ?

Cheers !

there is no screw drive at the mount

only nikon DSLR got screw drive system, canon their all build in motor.

nikon mount tamron the easilest way to know if its a build in motor or not is to look at the mount, if there is a screw drive coupling slot, its a no motor version. the newer model with build in motor will not have the coupling slot

[dimashp]

thanks for your reply. ok, i am as confused as before. is there a picture to show this coupling slot ? i wanted to purchase a second hand for myself but even the seller not sure about this. so both of us are...dot dot dot...thanks !!!

perhaps you might want to make known your camera model, and which lens you intend to purchase first.

[dimashp]

hmm...i'm buying D60 for my brother...i heard that i can't use the non-motor one there...not really familiar with Nikon...that's why, anyway thanks for your help !

ok..
anyway this is what the AF coupling looks like for nikon mounts. if the lens is AF and doesnt have the coupling, chances are the motors are internal.

hi clown and all !
yep, roger that ! thank you for all your help !!! really really appreciate it

can read more on tamron's website

could this be what you need to find?

means built in motor

I've the non-motor Tamron A16N Nikon mount, there's no AF/MF switch.

Quote: AF MF Switch Besides made in Japan, you can also see a AF MF switch on the new A16N II version. You can have the camera body in AF all the time, and changing the AF MF on the lens will allow you to focus manually or automatically.

The Tamron 17-50 is designated Di-II meaning it is only designed for cameras with 1.5x/1.6x crop. Di-II does not stand for whether the lens has an internal motor or not.

You bought the one w/o motor right?

And it's noisy? I thought motor ones are supposed to be quiet...I'm probably wrong then...i find my non motor one not that noisy...

Compared against Nikon's SWM, both versions are noisy! Haha... It's relative.

[dimashp]

yeah...Blur Shadow is right, it is noisier compared to Nikon or even Canon USM. But, great lens ! =D
