Summary: As usual I have a number of real-world examples of my results when using a super-telephoto lens. Next week I'll be following on from this episode, talking about Extenders as Canon terms them, or Teleconverters and extension tubes. These allow you to increase the focal length of your lenses relatively cheaply, but, at a cost. Tune in next week to find out more. Details of the BetterBeamer mentioned in this episode can be viewed and you can buy one too from the following page: http://www.naturephotographers.net/gs/betterbeamer.html You can also check out the other great gadgets at the naturephotographers.net gift shop here: http://www.naturephotographers.net/gs.html Check out the Wimberley Head that I use primarily for long lenses when using a tripod here: http://www.tripodhead.com/ Here is a link to an online Depth-of-Field calculator to have a play with and see the relationship between the focal length, aperture, distance to subject and size of the film or sensor: http://www.dofmaster.com/dofjs.html If you are interested to see all six images posted from the Kotokunuma (Pond) from last Sunday (February 5th, 2006) shot with the Canon EF 600mm F4L IS USM lens, follow this link: http://www.martinbaileyphotography.com/thumbnails.php?album=search&search=Kotokunuma_Feb2006
