Tamron 17-50 lens hood alignment

Hello all, hoping maybe someone can help me with this. I purchased this lens on the forum without a hood. I purchased an OEM hood for it and it does not align correctly. When you twist lock it on, it is rotated about 45 degrees beyond proper alignment. This is a petal hood and this cause slight vignetting at the wide angle view.

I purchased a second OEM hood and it has the same problem, so obviously it is the ring on the front of the lens. I don't see any apparant way to twist that ring and correct it.

Any ideas or advice is appreciated.

do you have pics??

The tamron has two versions, one with image stabilization and one without. Maybe, the lens hoods for the VC and non VC lenses aren't compatible?

I am unsure about this. Were you able to see if their was an OEM hood for the specific version of your lens?

Hoods are the same part # so no difference.

Looks like the filter ring can be adjusted (slightly loose), but I am not sure how...any thoughts?

You may want to call tamron on this one?

Found some information on how the front filter ring can become lose and how to tighten it. I decided to explore and found that someone must have serviced the lens in the past and the filter ring was not put back on correctly. I realigned it and all is good in my world.

Thanks for the input everyone.
