Lensplay.com is currently offline due to hacking attacks and insertion of malware. The site has been taken offline for your protection while measure are taken to ensure the safety of the site.
In the meantime you might want to visit my site BobAtkins.com. It contains lots of useful information about photography, lenses, cameras etc. and can probably answer your questions and provide more information than this site would have been able to!.
Sorry for the disruption of service here, but I'd hate for anyone to stumble on malware that someone has managed to get onto the site.
