I have a 55-250 and had been giving some thought to upgrading to a 70-200 F4 IS. What has held me back is how little I use the long zoom, the cost, and giving up 50mm. I absolutely want IS and don't want anything heavier than the 70-200 range.
Recently I've read some very good reviews here and elsewhere regarding the Tamron SP 70-300 VC USD. Also, a friend who has one, has shown me some excellent shots taken with his lens, including some BIF shots printed quite large.
The decision/comparison I'm asking about is between the 55-250 and the Tamron 70-300 VC. Anyone own both or moved from the 55-250 to the 70-300 VC?
