Thank you Popo for clearing that up. I'm going for the one you linked before, the one with 'Vibration Compensation'

. Now just to find a nice general purpose lens. For now, i contacted 2 stores that have the 'older' Canon EF-S 17-85mm f/4.0-5.6 IS USM. The 15-85mm is 2,5 times more expensive, and then the budget gets stretched a lot. If they can not get that lens, i'm affraid I will have to stick with the 18-55mm kit-lens, unless anyone has a good alternative for max 300 euro's.
For now the prices are:
650D Body, 850 euro
Tamron 70-300mm f4-5.6 SP Di VC USD, 350 euro.
So, either the Canon EF-S 17-85mm f/4.0-5.6 IS USM for 280 euro,
or t
he EF-S 18-55mm IS II starterkit lens for 99 euro.
So 300 euro would be the max to stay within budget limits.
