Wofie,the problem with the 70-200 lens it is very heavy unless you have a strong arm !i have just orded a canon 70-200mm F4 IS L-usm zoom lens from this site and they said they have them in -
http://www.t4cameras.co.uk and the total price including postage is £808 !and at warehouseexpress you would be paying £990 this lens is a lot lighter lens and you can alway add a extender and it will still be lighter,just a thought,cheers.Tony.
