Tamron AF 28-200 F3.8-5.6?
I have lens of: Tamron AF 28-200 F3.8-5.6, can i use this lens on DSLR camera NIKON D3100,
if not on which camera mount will will suit this either CANON, SONY
can you guide in this regard
If it's in Nikon mount, it will fit a D3100, but it may not autofocus.
Tamron only make lenses (they have done for decades), but they make them to fit just about everybody's cameras - so there's no way to tell which camera it will fit unless you know the lens mount.
Look for an inscription around the base of the lens or consult a dealer.
Maybe.
It will mount your D3100 only if it comes with a Nikon mount.
Have you tried mounting it? If it does not go in perfectly (and end with a click) then it's not compatible. Tamron makes lenses for different cameras including Canon, Nikon, Pentax and Sony.
Don't expect answers to be different than the ones you got last week when you asked this same question.
