Well today after long wait i got it. Ordered from Adorama.com total cost to me was 57,000 Pakistani Rupees or 712$ it is a cheap lens but due to non availability at dreaded Pakistan's official Canon dealer MBM i had to order from USA and all such imports are subject to import duty and taxes .
Intitial expression about lens is good i love sharpness of this lens. I hope focus speed was little fast but it is not too slow either. If you are L edict you will notice difference in operations of the lens they are not bad but L is tooo goood.
Here are two Portraits shot with This lens Shot wide open and converted to JPG from CR2 in DPP default settings. Canon EOS 400D hand held
