I was out walking using my camera, then i notice something.....the front part of my lens, its woobly and loose...ahhh i though its suppose to be tight?? anyone having the same problem as me?? now my uv filter is woobly too since its screw on to that front end...

the pics is here circled in red


Attached thumbnail(s)

mine is still tight as new.. did u knocked it accidentally?

oh my... didn't think it was that fragile...

mine still ok oso, quite new though

No problems on mine since I got it.

You'd better return it to the shop for a check and just in case, a swap.

just return already, he say this is rare problem but fixable..........

stupid la when go the shop, my front lens pop out already........now don't know if got fungus masuk already or not........crap...anyway take care of your lens that part, i think its cause by my lens hood i left it on the camera all the while...

lens hood on the camera all the while?
huh?

Fungus can masuk just my air suction when you zoom out your lens...

But seriously, your front lens element popped out?? Sounds like poor quality lens that the QC checks missed at the factory... or maybe a bad design - the designers should have know, for example, that lens hoods can potentially act as a lever to pry that section loose from the others, and which user doesn't put on the lens hood on a lens almost all the time?

my lens hood is always inverted.........but dont know la its that part and its stupid

There is no difference in terms of magnitude of applied moment/torque when your lens hoods is mounted either inverted or in operating position:

very nice diagram, but i think it's just poor qc from tamron.

yea i think sigma better ot just go for L lens la

Tammy made in china la
what do u expect
