Where I have both the Tamron 70-300 Di USD and the Sony 70-300G, personally I find it hard to tell the difference in quality between the 2. Both are very impressive pieces of kit which give great quality pictures.
Not 100% sure but I have been told tamron lenses are made by Sony in their own factory. Hence the similarities. (I was told this by a camera shop who I do trust but feel free to correct me if I'm not quite right)
I only doubt it because if this is so why the price difference?

There are a few lenses where Sony and Tamron share a design, but I don't know if they are made in the same factories. The 70-300 USD and 70-300G certainly are NOT the same lens - but they are close in overall quality. The Sony has the edge, but also has a price premium to go with it.

Must admit I went to Wex photography in Norwich today. While I was there I asked. They said they hadn't heard either. Maybe it is just a rumour then due to the similarities.

Amanda, Mrs C and I shoot mostly birds and the odd animal.
You will not be disappointed with the 70-300G I am confident of that.
For settings-
I always use aperture priority because I want to choose the DOF myself.
The focus is set to spot because I want to focus on the eye and this lets me do it.
Metering is also set to spot metering as I want the bird to be correctly exposed.  If the background is too dark or too light - so be it- I will fix it later.
ISO is at 200 for a bright sunny day.  400 if it is overcast and upwards from there if I have to.
We each have a monopod to aid the arms otherwise you are holding the weight for extended times waiting for the right shot.

Since getting the A99 I do a lot more manual focus using the focus peaking that the A99 and A77 have.  ( I do not know about the A57)

Now you can show us the fruits of the purchase.....john

I also use Aperture priority fro the majority of my shots.

I tend to have focus set to Local rather than spot - I like having the option to quickly change to an alternate focus point if that suits the composition better.
ISO starts at 200, but I will raise it to as high as 1600 if I need to to get a reasonable shutter speed - I can correct a bit of noise in PP, I can't fix a blurred shot!
(That's on an A900, where you feel the noise limit is will depend on your camera, and personal preferences).

Amanda, if you shoot in Program mode, you can adjust the aperture and shutter speed as needed, and the camera will automatically set all the other exposure parameters.

That way if you want to control depth of field you can, or if you want to freeze/blur action you can... and do both without having to worry about setting the other exposure settings manually.
There are people who actually think LENS stabilization is better than sensor shifting!

I mainly use aperture priority to control depth, but if I want a faster shutter speed, then I just select  a wider aperture by using the thumbwheels on the A550 and A700, no real, need to change shooting mode

That works too.

I like Program mode because I can adjust BOTH at the same time if necessary. ;)

It's fun just playing around with exposure parameters... we could NEVER do that back in the film days without spending a fortune and waiting a week. :(

A hidden gem of a lens is the old APO Minolta 100-300 mm zoom. You can find them on eBay and I purchased one from a Japanese vendor who had an eBay store. The lens is remarkably light and it autofocuses on the a77 and is tack sharp. For a thirty year old lens it does very well. Here are a couple of zoo shots to illustrate its capabilities.

Nice!

Shot through a wire fence I assume... but on which camera?

Thank you,

Shot with the a77. I had to position the lens so it would should through the clear area of the cyclone fencing.
