I might even go 10 second for good measure. I've seen 2 second timers still have movement with longer lenses.

I'll go even further; I set timer to 10 seconds and walk away, at least 15 feet. I've noticed that 600mm on a crop tends to sometimes pick up even my slightest move if I stay around the tripod (breathing, heartbeat etc.) :)

Yeah, it's very very sensitive. I think I might pickup that better beamer flash attachment and try that out. I saw some really good examples using it, setting the flash to daylight fill flash or something, to balance out the image. That would also probably reach the Eagle I was shooting, like 80-100ft away.

1/1000th still isn't consistently hand holdable? The longest lens i've shot is 250 on crop/300 on ff; so this would be uncharted waters for me.

oh yeah it is, we were just talking about test photos from tripods. I don't have a studio with pro lights, so I need slow shutter speed to test at low ISOs, that's why I need to do everything not to mess up a 1/10s shot.

I just noticed something less than positive; the Tamron seems to override TC reporting.

Just tried the AF at f/9 on the 6D, and again, like in the darkness of the indoors yesterday, pointing it outside, AF is reliable in sunlight only up to 450mm, and is sketchy at 500, and near-impossible at 600.

Do you mean that it completely overrides TC reporting such that the EXIF data doesn't reflect the use of the TC? Or that it'll try to AF when it shouldn't?

Given that the 6D is officially claimed to AF only to f/5.6 I couldn't be surprised that AF at f/9 doesn't work - even in sunlight... or have I misunderstood the point you were making?

I've never used a flash extender, but I can really see how it would be useful for these focal length limited + need a TC + light levels probably going to need high ISO situations (and for the purposes of fill in flash in backlight situations, of course).

There's a nice DIY one here: http://www.digitalbird​photography.com/window​s/4.3.html (external link)

The bottom line is that the camera does not see the TC at all, and I suspect that with this lens, it might not see any brand of TC. Not seeing the TC means that it will attempt to AF.

Thanks for the link! yeah, this is a good example I guess, or similar situation I had. Although this is a little too bright, but still better than very under exposed.

Interesting. I'd have thought the TC's internal electronics would dictate whether the camera could "see" it, so perhaps it's part of some trick the Tamron's doing to (presumably) report f/5.6 at the long end (rather than f/6.3, which I assume would disable AF on most bodies).

It will interesting to see how fast Tamron can deliver the next large shipment to the stores to fulfill the backorders and maybe put a few on the shelves. I wonder if that will happen in less than a month.

On the way... will post my thoughts (and of course some images in the other thread) when I receive it. It's expected here the middle of next week.

I was told from Adorama about a week ago it would be another two weeks. SO I am guessing we will see them around the first of Feb.
