So is this a fault Tamron have addressed with newer batches?
Regardless of the warranty and customer care after purchase. A product should work as described out of the box, not need to be sent back as soon as you purchase for an updated chip to be installed to stop it draining the battery. A lens that is not a perfect match for your camera is fairly normal which is why there is AFMA. Apples and oranges.
I have got the lens 2 days back and am initially happy. Basically I don't expect an IQ equivalent to my 500 f4 . It is a very good lens for the budget. I opted for this because I am struggling with my old 100-400 over reach. Iq wise the new Tammy is almost as good as the 100-400 and the extra reach is welcome for a day to day use . The only thing I can complain is a little slower auto focus when it is focused on the other end. Ev en with flying birds I feel OK with the lens. This is an example of the flying rock pigeon with the exif data....

I'm still very much interested in this. But have yet to find the time to my local camera store to chat to an assistant about it and the price.
When some of you mention about needing time to learn how to use a 600mm lens. Are you mainly referring to the desire/need for a tripod or monopod? The difficulty of handholding? Up to now the longest lens I have used has been 300mm. Just curious as to what I would be in for if I pull the trigger and buy it.
I never considered the Sony software options, the timelapse ap sounds pretty cool.
Here is one I made today morning ... actually I didn't, the camera did ... all I did was put the camera on my office windowsill, lens tilted upwards with the help of a lid (of a Jam bottle), went into the menu selected "Sunrise Timelapse" from the application list and let the camera do its thing ... this is unedited footage, straight from the camera (other then whatever youtube does to it while uploading) ... did not use any PP or editing software (I pulled out the SDXC memory card from the Sony a7, inserted it in the laptop and uploaded it to youtube).
By the way, this is a dry and dusty desert country, so we don't get any magnificent sunrises that one gets to see in most countries ... in fact what you see in this video is one of the very few good days that we have in a year.

With all due respect Don testing a 600 lens at 20 feet is a bit ridiculous - IMO!
I intended to test it at about 100 feet, but it was -26C and windy outside... I am going to retry the test the next nice day that I am home.... I was thinking of a bird-sized target at 100 feet and then another target at around 300 feet, plus trying some additional F-stops....
I am looking forward to trying out this lens.I'll give a comparison with the 300/2.8 II +TCs when my Tammie arrives after next weekend. I'll even show my favourite medieval brick chimney for Mac.
If you get a good copy I think it might be as good as 300/2.8 IS (and maybe IS2 on a good day) with converters AT 420 and 600 without the darned inconvenience/extra cost. To get a half decent 600 with the 300/2.8 IS you have to stop down to f8 anyway.
Here's a wide open Helios 44-4 shot. I find it has a bit less micro contrast than the 44-2, but also functions perfectly on a full frame body (no mirror hang).

I also have a 6D and am interested in the 44-4 version. What adapter to you use?
