Will Tamron 80-210mm f/4.5-5.6 Lens autofocus with my Nikon D3100

You didn't specify the make of the lens. Assuming the lens has a Nikon mount then yes, it will mount on a D3100. The big question is whether it will autofocus on the D3100. The D3100 does not have an autofocus motor, relying on the lens to have one. Not all lenses do. Nikon designates lenses with an autofocus motor as AF-S. Other manufacturers use different designations.
If you need further assistance, feel free to reply to this post and give the make of the lens.

Tamron makes their lenses with a variety of mounts. A lens with a Canon mount, for example, will not fit a Nikon. Assuming the lens has a Nikon mount then yes, it is compatible with the D60. However, the D60 lacks an autofocus motor, relying on the lens to have one. Some Tamron lenses have such a motor, some do not. Such lenses will not autofocus with the D60, but everything else still works, including manual focus.

That lens will work with the D3100, except for the autofocusing. In order to autofocus with the D3100, you need AF-S lenses, such as the AF-S VR Zoom-NIKKOR 70-300mm f/4.5-5.6G IF-ED or the
AF-S DX NIKKOR 55-300mm f/4.5-5.6G ED VR.

hi there,

i used d3100 a few months ago,
for your information this camera only support autofocus with built-in motor lenses
if you have interest on wildlife, you should use tele-lens whose focal length above 200mm
if Nikon lenses cost you too much, you can choose other lenses from Tamron, Tokina, or Sigma

for family photograph, the kit lens is able to do this (18 - 55mm),
for natural beauty, i myself use nikkor 50mm/f 1,8 which has great power in low light condition

hope this will help

The D3100 can't autofocus with this lens. The D3100 does not have a focus motor, depending on the lens to have one. The AF-Nikkor 50mm doesn't have a focus motor, depending on the camera to have one.

To autofocus, you need lenses designated AF-S.

The Nikon D3000 does not have a focusing motor built-in, relying on the lens to have a motor. The Tamron AF 55-200mm does not have the necessary motor; it only auto-focuses with Nikon cameras that have the motor in the camera body.

For Nikon lenses, you need lenses designated AF-S. For Tamron, you need lenses designated USD and/or BIM.

That probably wasn't the answer you wanted to see, but there it is.

Tamron makes their lenses available with a variety of mounts. A lens with a Canon mount will fit Canon cameras but not Nikon cameras. A lens with a Nikon mount will fit Nikon cameras but not Canon cameras. As long as you buy a lens with a Canon mount, you shouldn't have any problems.

All Sigma:
50-500mm f/4-6.3 DG
50-150mm f/2.8 EX DC HSM
70-200mm f/2.8 DG MACRO
80-400mm f/4.5-5.6
100-300mm f/4 DG
120-300mm f/2.8 DG

This is a lens for Sony/Minolta cameras. It is not compatible with the Nikon D90. Hence a Teleconverter for Nikon will not work on this lens to mount it to a Nikon D90.

Autofocus function on the D40 only supports lenses with the
AF-S feature, which have an autofocus motor built into the lens,
instead of using an autofocus motor drive built into the camera.

The Tamron lens you have, does not have a built in motor and
the autofocus function relies on the motor drive in the camera.

It will not work with the D40 or D60, but it will work with other
Nikon digital SLRs, such as the D80. Need to get an AF-S
type lens or upgrade to different Nikon digital SLR. Unless
you do this, you will have to manually focus the Tamron lens.

All of the Nikon DX (for digital) series lenses are also AF-S
type, so they will work with the D40, which is designed as
an entry level digital SLR, therefore it is intended primarily
for use with DX lenses, which are typically sold in a kit with
the D40. Most common one is Nikkor 18-55mm DX AF-S.

Other Nikon AF-S lenses made for film cameras (FX type)
will also work with the D40, but these tend to be expensive
professional models. DX series lenses tend to be more
affordable. You might consider the 18-200mm DX AF-S
as an alternative to the Tamron, but these are not cheap.
