Thanks alot for this vid! I was debating whether or not to the the 70-200 for my D40 as it I cannot afford the Nikkor lens right now. Good to see that it isn't too slow when auto focusing.

yea the focus speed is fine...i really dont know what everyone is on about when they say it is slow.....sure its 'slower' than nikkon AF-S but hey look at the price difference. This is a great lense!

Thease tests are irrelevant because this lens is hunting, not focusing on a target and will behave differently doing so.

Thats why they dont test like this in reviews.

@chazeman2 Yes I have this lens but on the sony alpha mount (a700). On the sony mount the af is driven by the in body motor and is reasonably fast and Ive found it very accurate. Some other mounts have an in lens af motor though and I'm not sure what their af speed perfomance is like.

@Drinapropriatetouch interesting. i finally found a video on here showing the lens focusing on something in good light and it really did seem to go faster. thanks. do you own the lens??

[Drinapropriatetouch]

@chazeman2 No problem, when there is good light & there is an object to find focus on the camera's af sensor will have something to lock onto and the camera will move through the focus range quickly and find it, if it is low light or there is no object to focus on the camera will slow it's focus speed down so that it does not accidentally miss what it is trying to focus on. In other words the camera is slowing the af speed down to give itself a better chance to find focus on something

@Drinapropriatetouch you have said this on multiple videos. What is going to make the lens focus at a different speed if it is focusing on a subject or if it is hunting?explain.

Tamrons auto focus motors suck balls....

I think the Tamron 70-200mm will do fine in most situations, it may be just a tad slow but it'll produce. Besides it's fairly sharp wide open and it beats manual.

@JC040696 I don't remember if anyone said 'useless test' . The hunting speed is not the overall speed of the AF. As far as not watching videos like this the title is "Tamron 70-200mm f2.8 Nikon D40x" could be a review, could be anything about this lens as the description isn't seen in the thumbnail. I was researching this lens hence my interest

I don't like these videos is because they may misguide people as to how this lens would perform as hunting is not focusing.

[JC040696]

@Drinapropriatetouch first off, these 'useless tests' aren't really useless. the hunting speed, lets us consumers know the overall speed of the lens. if you think videos like this are irrelevant, why watch them in the first place?

@MadmanDKDK This is a great lens for portraits. For those that are interested in sport fotography this might be a really bad choise (sigma has better focus speed). However when it comes to focusing i rarely find the situation when i have to focus from 0- infinity. A L lens is 3 times more expensive than this lens, so i don't know it is justify to spend that amount of money if you are not making serios money out of photos.

@gecho82ss

Compared to my lenses which are Canon L series - that is insanely slow. So there is a point to the masses that say this lens AF is SLOW! Get something with a USM or HSM instead.
