The _real_ difficulty with this lens is that it fits nicely in the palm of your hand. So the temptation to use it that way, despite numerous examples of it not working, is very high.

It's sad, how we delude ourselves. 8-) m ----------------------------------------- Email sent from www.ntlworld.com Virus-checked using McAfee(R) Software Visit www.ntlworld.com/security for more information
