Could be seeing the VR snap the image into steady ?

Sounds like it. Is it annoying or distracting?
I found it comforting and reassuring :t:

Haha - yes! Reassuring to know it's still there, as it's pretty much undetectable otherwise.
Apodidae, At the risk of repeating myself ...... it only does it sometimes ..... it's probably something to do with limits of the system's correction capability, and the particular frequency and amplitude of the movement at the time - just part of normal operations (I'd be surprised if all Image Stabilization systems didn't show something similar - effectively resetting).
I don't know whether the system computes any variation depending on the shutter speed settings, or if it just operates in response to the particular shake input - I doubt Tamron would disclose the proprietary operating system - just be thankful it works. For me I find a particular sweet spot at 1/400th sec which is pretty insane for 1200mm
(you'll see for yourself when you hook it up to the D7200 to test out).

Went back to Jessops with D7200 body to test out the two lenses and, Sod’s Law being what it is, the Tamron was a Canon mount and they didn’t have a Nikon mount.
Anyhoo, onto the camera went the Nikon 200-500 and very nice, and well-balanced, it felt too.
Didn’t mess much with the camera settings for a test, just left it on the settings I’d used last. Aperture Priority (wide open) ISO 400, CH shutter release, AF-C Single Point and switched the lens VR on.
To my untutored eye the results look okay and the VR slips into operation very smoothly.
Took a few (50+) photos mostly at 200mm & 500mm and I’m pleased with the results and very impressed with the ergonomics, build and ease of use of the lens. As it’s a native lens, I may not bother trying out the Tammy (assuming I could get hold of one to try)

All VR systems can jump the image around in the viewfinder frame-to-frame. Some lenses have VR modes that smooth it out to make it less jumpy. I am not really bothered by VR jump when I see it (which is rare). I do not think it is particularly an issue on the Tammy. Some lenses have a VR mode that is on while 1/2 depressed on the shutter to smooth out the VF, and I'm not sure if the jumping issue you mentioned is related to trying to use that mode.
If you like the 200-500 f/5.6, it's a nice lens and has very good center sharpness, which on a DX sensor means pretty good edge-to-edge sharpness. And the f/5.6 lets in 1/3 stop more light. But you lose that last 100mm, which is a bit noticeable. That last 100mm will actually be 150mm (DX mode) or 200mm (DX at 1.3 crop).
I use the 500mm f/5.6 prime and while I do miss that last 100mm, I have enough pixels on the d850 to crop my way into it and the prime has excellent image quality that holds up to major cropping.
If they have a canon 7dmii loaner, you could try the lens there, though it would be a little difficult to compare.
I think functionally, the two things to look at is the number of turns it takes to zoom and the f/5.6 vs f/6.3. If I remember correctly, the 200-500 takes a lot of turns to zoom and the Tammy is quicker. But I rarely zoom, so that is not much of an issue for me.

I was reading a review the other day which compared Tammy A011, and G2, the Niki, and Sigma C, and Sports (150-600). The G2 actually came out on top for centre and near centre sharpness at 600mm, and also at 500mm. At 600mm the Sigma Sports only edged ahead for full frame edge sharpness (which is irrelevant on a crop body), and the Niki only managed to pull slightly ahead of the G2 over the range 200-400mm.

Very interesting that the Tammy G2 knocked the Niki off at 500mm as the Niki is widely regarded as a sharp lens and great value for money (if a little heavier ~300grams than the rest - except the Sigma Sports, which at 2.7~2.86kg is not on too many lists for handholding).

Thanks Marc and Chosun, I’m still interested in the Tammy if I can get one to try out on my D7200. As far as zooming goes, I think the Nikon zoomed fully in less than 180degrees but I wasn’t really concentrating on that. I’ll have a look at that link you posted and put it into the melting pot with all the other reviews and YouTube videos.
It was actually just nice to finally, physically handle a lens and get it on the camera body.

Went in to Wilkinson Cameras, in Liverpool, today as they had kindly got a Nikon fit Tammy 150-600 in for me to try on my D7200 body alongside the Nikon 200-500. Shot a few pictures of the same views with both lenses and was quite impressed with the handling of the Tamron and its zoom range. The staff were inclining toward the Nikon for the constant f5.6 and its native status but, to my untutored eye, there was little difference apart from the longer reach of the Tammy.

The 5.6 aperture is where the nikon wins out and can get you that extra shot that you may not get with a smaller aperture lens when the light is less than perfect.Advantages and disadvantages to both lenses but as i said earlierthe 200- 500 on the d7200 is a winner.....you cant go wrong.
Half a stop will not make that much difference, go for the one that feels right.

I have the Tammy G1 150-600 and find it a great lens although it does not focus that quick, but I believe the G2 is much better). The longer reach will help in the long run but you may find a native lens focuses a lot quicker so you miss less shots. Not tried the Nikon lens being a Canon boy but it would be interesting to see if you crop the image from the 200-500 to 600mm if you loose any detail. With the Canon 400mm f5.6 fixed lens its often said you can crop to 600mm and get just as good an image as if taken on a 150-600 lens (be it Sigma or Tammy).

Isn’t it a full stop at maximum zoom - 5.6 as opposed to 6.3 or is that half a stop?

You can crop quite a bit with the 200-500 and not loose detail......it's a very sharp lens.

The Tamron G2 150-600 is meant to have marginally better central sharpness at 600mm than the Nikon 200-500 does at 500mm according to the test report I posted earlier somewhere. As such it would have the better cropability. Agree with what you've said about holding onto low light longer too, though there's not much in it.
I have no doubt that unit to unit variation with these lenses could tip the balance one way or the other. Your results when using the 200-500 are excellent Neil - I don't recall having seen sharper samples casually browsing other's 200-500's :t:

f/5.6 - f/6.3 - f/7.1 - f/8
So it is 1/3 of a stop. Assuming you have the same SS and f/stop between the lenses, one might be ISO 800 and the other ISO 1000 (1/3 of a stop higher). f/5.6 vs f/6.3 is not such a big deal as far as overall lighting is concerned, but it can be a big deal for autofocus. On the Nikon platform, there is a significant change in what AF sensors get used above f/5.6. Though for the d7200 in specific, it looks like you get all 51 AF points out to f/7.3, then at f/8 or above it is down to 1 AF point.

More lens reviewing in-store and this time also had a look at the Sigma 150-600 but decided I didn’t like it as much as the Tammy or the Nikon as the zoom was stiff and turned the “wrong way”
December is getting nearer and with it a decision about the lens and I’m now veering toward the Tammy. Extra reach and less weight are outweighing the constant f5.6 and the Nikon name.
