Yes Kris, that's what I thought originally as well...the reply from thegame81 made me question this though...unless he shoots a Canon or didn't check but went by the reviews as well. Can you imagine what the reason behind this might be?

Apologies for the misinformation. Just checked with my d7100 and it goes to f6 at around 350mm and f6.3 around 450mm.
? for users of this - at what speed are you turning the VC off? I understand its not really necessary when shooting 1/2000 but it still helps me with composition if Im lifting the monopod off the ground. Any pluses or drawbacks to leaving it on? I generally only use this on a monopod

I never turn off stabilization if the lens has it. I haven't noticed any issues with the VC on at faster shutter speeds.
Very nice series thegame! Love the GBH, you were really close!
I generally turn VC off at 1/1000th or higher.. I only shoot handheld also. I've noticed pixel level blurring if I track a bird with VC on at 1/1000th or higher..
I can't believe those bird shots! I’ve been looking for something lighter then the D3S/70-200f2.8 I carry in the woods, and was reading about the D750 and D810 (I have the D800E). But the bodies are another story - one site, “photography life, I believe, has compared the two bodies and posted a bunch of photos taken with this Tamron - I couldn’t believe them either. I signed on here to see what I could find about the two bodies (AFC and frame rate are really important to me), but now I have to go look at the specs on this lens. I have to use the Nikon 600 f4 on a Wimberly II head, and once I had to climb over a bunch of high rocks and ended up hand holding that beast because there was literally no space to set up a tripod. Now back to look through the rest or your images!!!
Wow. The D4s dog shots are spectacular too. Dog action is my most often photographed subject, and those posted here are absolutely top quality. Very, very impressive (both the lens results, the camera being able to AFC with what appears to be a fairly slow lens, and the processing quality). Birds are my D800E subject, so finding this Tamron thread is a dealt treat (and eye opener too).
Sorry for the off topic...just to close the issue regarding f stop at 400mm being different on Canon and Nikon...here's the official response from Tamron:
Thank you for your inquiry and the interest in our products.
The aperture displayed stays the same in most cameras, but some SLR cameras ( Nikon) are equipped with a feature that shows the effective f-values, and smaller open aperture values are displayed when the lens / zoom barrel is extended for close-up photography.
This phenomenon is not a lens defect or flaw, but is a camera characteristic.

Thanks for reporting your finding. My sigma 150 macro does this. Didn't realize the Tamron does it too.
Is there a Japanese and US version of this Tamron lens? If so is there a difference such as warranty, etc like Nikon US vs black market version? I just received one through amazon and it looks like a Japanese version. No biggie unless there is a negative about the Japanese version?

@Tubby, better check with Tamron. I've seen some posts about sellers on Amazon not being authorized and therefore no US warranty...
Yep found out there is a US and Japanese version. US version has a 6yr warranty and Japanese has 1yr but all warranty work on the Japanese version has to be shipped to Japan. Unless the seller on Amazon says, "US Warranty" which I've only seen one, I would not trust them.
I have a new one coming from Amazon Friday I've had back-ordered for months. I hope it's the US Version.
I was trying to decide between this one and the Siggy 150-600 and I just cannot see the justification for the extra 900.00 Thanks for posting these awesome shots everyone!
I felt the same fmphoto...I checked the samples from Sigma on the internet and then got a chance to try out the Tamron in person....after seeing the shots from 600mm and wide open, I couldn't see why would I need to spend extra money and carry extra weight around.
