The big picture: Sigma 18-250 HSM vs Tamron 18-270 PZD for Sony
 |
| Side-by-side comparison courtesy of dpreview |
There are 4 feasible "super zoom" lenses.
The most recent are the Sigma 18-250 HSM and the Tamron 18-270 PZD.
There are some reviews, but no real head-to-head testso it's seriously difficult to compare the alternatives; to make things worse, the Tamron PZD model replaced an analogous (but fundamentally different) screw-drive lens with a similar name, so many reviews actually describe the old model.
I will quote below some paragraphs that I found interesting, with some notes in color and some highlights.

A Canon lens for my Sony Camera
 |
| Canon 77 Close-up Lens 500D, for Lenses 70mm to 300mm, Double Element |
The 500D close-up lens incorporates a double-element achromatic design for maximum optical performance. It changes the closest focusing distance from infinity to 500mm.
It has the same mount as a 77mm filter, so it can fit on the Sony 70-400, with some interesting results:
