Rob.
That's a shame (though makes sense, why would you keep both ). Whilst you can't do any direct comaprisions, it would be very interesting to hear your subjective views on the two of them.I no longer have the tamron so can't do any direct comparisons I'm afraid.
A quick play with the lens as the light starts to improve here.
This is with 1.4x kenko 300 dgx, 560mm, iso800, F8, 1/500 on 5D3
I already prefer it to the tamron 150-600mm in terms of size/weight.
50% crop and slight sharpen for web.
I don't have the canon extender because it wasn't compatible with the 70-300L that I owned previously.
I doubt that anyone outside Canon will know exactly when any offers will be coming, and personally I'd doubt if such a new lens will be in such an offer, Robin, but equally once stock is plentiful, I'd expect prices to drop fairly rapidly, but again, by how much?
All very much up in the air at the moment.
If you're heading for a Gimbal then I'd suggest the longer option. The balance point changes considerably if you add a converter, body with or without grip, 1srs body...a longer plate allows a more flexible setup IMHO...... I need to decide whether to get a 75mm or 100mm long plate.

I have the arca swiss P0 ballhead with universal quick release plate 48.
http://www.robertwhite.co.uk/arca-swiss-monoballfix-quick-release-camera-plate-48-universal.html
It works fine with the lens.
I think the actual foot length (before it begins to curve) is about 55mm
In regard to ARCA plates, for my mkI 100-400 I got the Whimberly plate specifically designed by them for it and a key factor in the choice was that it is shaped with a slight curve that matches the curve on the foot thus only needs a single screw to attach it as the shape is designed to stop twisting.
Robin, that's the wrong kind of A-S plate - it's for the smaller A-S dovetail. The standard dovetail that everybody copies is 38mm wide.
I would take Bob's advice and go for a longer 100mm plate. One of the advantages of the A-S system is you can slide the lens back and forth for optimum balance, but that position changes when you zoom, or attach a heavier camera with battery grip, or just when pointing the lens up or down. I doubt that a longer plate will get in the way at all.
[snip >]... They are very strong and when done up tight the rubber grips bite into the grooved underside of the lens foot securely, so very unlikely they're going to rotate, especially considering that kind of twisting force doesn't apply to lenses mounted via a collar. But that's just me and you might think differently, just sayin'
Edit: this might come in handy - with a longer A-S plate that overhangs the lens foot, you can drill a 10mm hole in one corner and the Black Rapid spring-clip will fit directly to it.
I simply swing the tripod mount up to the top when hand holding (300/2.8 and 200/2) so it doesn't really matter what's attached to it.Thanks, 'Box B'
Here's a solution using an even longer plate than 100mm but I think that the plate would then be too uncomfortable when handholding....
....According to Robert White, who are officially appointed UK dealers for Arca-Swiss and stock their whole range, that #802284 plate which I linked to is the right plate for the Arca-Swiss P0 version I am thinking of getting. I am told that "Arca-Swiss are fed up with having their plates copied" and have revised their head designs accordingly.
<snip>
That plate is for the P0 head fitted with the MonoballFix quick-release, this one http://www.robertwhite.co.uk/camera...ll-and-socket-p0-with-monoballfix-device.html But the one I thought you were getting is this, with Acratech clamp? http://www.robertwhite.co.uk/camera...and-socket-p0-with-1-4-3-8-threaded-disk.html Acratech uses the standard A-S dovetail, 38mm/1.5in wide, as does everyone else.
As for Arca-Swiss being fed up with everybody copying their system, well, that horse bolted long ago
I take your other comments too, though I'd say that a 100mm A-S plate properly attached is nothing like a little M'frotto RC2 jobbie. But each to their own, I'm just throwing a few suggestions out for you or anyone else, whatever works for you is cool
....I was at one time considering the A-S P0 with threaded disk but didn't fancy the idea of having to use Loctite to secure a third-party plate-platform, so changed to consider the A-S P0 MonoballFix Device head which only appears to take 32mm plates.
In deciding the Acratech Swift Clamp (which is currently in stock at Bob Rigby) and which takes Wimberley and other 38mm plates but not the A-S 32mm plate (now confirmed by Acratech), I am now giving serious thought to the very compact Acratech GP-SS ballhead! Then I know for certain that everything will fit and open and close superfast and with the same lever mechanisms.

I am very much appreciating your suggestions, Richard, and everyone else's - It's how I have arrived at this range of choices now. Plus, as you say, all this info is potentially helpful to others who read this thread.
Acratech heads are very good. I love the design and engineering, they're very smooth and strong, light and really nice to use, good choice. Technical performance isn't quite so good as some others, particularly considering the price, but we're really comparing levels of excellence
Hi Robin
If you opt for the Acratech GP-SS ballhead, why are you thinking of the lever-clamp version rather than the screw clamp (which is slightly lighter and slightly lees money)? Reading some of your various posts on ballhead choice, I rather thought you favoured the security of a screw clamp.

The cost keeps mounting Robin - have you sold that 70-200L f/4 yet?....Actually I have now decided to go for the screw clamp on the Acratech GP-SS ballhead and the lever release on their Swift Clamp which will hang off my BlackRapid strap. It makes sense to also buy the Acratech 100mm plate to live on the lens collar foot of the 100-400mm.

I am toying with the idea of buying the Kirk MPA-2 monopod head for use on my Gitso GM2541 monopod - it only gives me a tilt function rather than a full ballhead of course, but I have lived with a basic Monfrotto 234 tilt head for some time, and think a monopod tilt head function is all I personally need for my style of bird photography. And anything is better than the 234 mechanism!

For a minute there I thought we were going to have a post about the MKII 100-400mm.
....Sorry for going slightly off topic there, Mike.P - It is the nature of discussions and it meandered to what is best to handle a 'pod supported 100-400mm Mk2. I'm sure this is not the first time nor the last time that such meandering will happen
It just gets a bit annoying when you subscribe to a thread for info and it flags up when you log in saying there is new content and it turns out to be nothing at all to do with the original topic.
Whilst I agree that there is always a certain amount of off topic conversation Robin I would hardly call 22 posts "meandering".
Didn't you start a gimbal thread or suchlike anyway?
