Here is the crop of the subject from the shot above with a little more exposure added to it:

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?
Not much of a shot but here's the twist. It was shot using the 6D wifi from my computer in warmth while it's -20 C on the deck!
However, I'm not too thrilled as I've been having problems keeping the connection and can't get it back. Anyone have experience with this 6D wifi and know the typical pitfalls? The EOS utility and live view shooting seems very clunky and I was getting pretty frustrated with the slowness of focus and the time transfering files to the computer etc. Seems a mixed bag.
For all of you birders, here is a pretty amazing review of the lens by a guy comparing it to the 600mm f/4L IS (original version):
The comparison images of the Red-Tailed Hawk have the bird occupying half the height of the frame. At that size, the image should be extremely sharp with fine details of the plumage visible. You can see that the head of the hawk from the Tamron is soft. All of the images I have seen at 600mm f/6.3 are soft to varying degrees, as you would expect from the measured MTF charts published by different reviewers. However, the lens gets significantly sharper at f/8-f/11 and the lens should be very sharp. So would someone please post some shots at f/8-f/11 so we can see what the lens is really capable of doing. How about it Don?
