Hi all,maybe some one could answer a few questions for me,firstly i have a olympus e410 with which i use a zuiko digital 70-300mm f4.0-5.6 lens,would i be able to get a tele converter for this lens and if i can,what exactly would it do,would it enable me to take pictures at greater distances ?,any advice would be appreciated by a total novice.Thankyou.
