Very few people have read what the OP has stated. He wants more range on the long end than 105 and less weight than the 24-105L. Pretty slim pickings. The only two that I can think of are the Tamron 28-300 and Tamron 28-300 VC.
I agree somewhat, but very tough to get more range than the 24-105 while retaining decent quality. Those older tamrons are very weak in IQ and TS might be better off downgrading to crop and picking up their ultrazooms.
You can make a point that the 24-105 has comparable IQ, and somewhat good range, but as a true 28-300, I think crops would beat any other FF alternative. TS can go nikon, which makes a decent 28-300.
