Considering what you want to do and your budget constraints, I think you made the best choice.

I understand the eBay distractions. Gems do occasionally pop up, especially for the Sony/Minolta A Mount. But the Tamron 70-300 Di LD is as good or better than anything else you'll find there in the same price range.

Unless you've got something specific in mind, I'd skip the filters. Photographic lenses are very complex optical systems. Adding another optical element can degrade image quality, and if it's a cheap filter it can introduce some flaws of it's own. If you'll be doing a lot of shooting, where a good portion of the image will be the sky, a Circular Polarizer can be a nice addition, and in bright light a Neutral Density filter can be useful. But if you're going to use a filter, make it a good one.

Forget the Sigma. The Tamron is a better lens.

I don't actually think much of the analysis you linked to.
  1. At 200mm and f/5.6, the center crop for the Tamron is sharper and has less CA.
  2. At 200mm and f/8.0, the center crop for the Tamron is sharper and has less CA.
  3. At 200mm and f/8.0, the edge crop for the Sigma is sharper and has less CA.
  4. At 55mm and f/4.0, the center crop for the Tamron is sharper.
  5. At 55mm and f/4.0, the edge crop for the Tamron is sharper and has less CA.
  6. At 55mm and f/8.0, the center crop for the Tamron is sharper.
  7. At 55mm and f/8.0, the edge crop for the Tamron is sharper and has less CA
Optically, I'd call the Tamron the better lens.

Just glancing at the review in question, I see mention of the rotating front element. I have the sony 75-300 and it rotates. I really noticed it when I tried to brace the lens hood against a chain link fence to take a pic thru the hole. I couldn't!

Is there a 300mm zoom that doesn't rotate?

Dyxum's lens reviews specifically mention whether a filter rotates when zooming or focusing.

The Sony 70-300 'G' doesn't.
