    Advice re. extension tube for Canon 35-350mm lens.

    Thanks for all advice. I checked and Jessops no longer do their tubes, so I'll probably go with the Kenko set.

    Advice re. extension tube for Canon 35-350mm lens.

    I'd like to get an extension tube to put between my 30D and my old 35-350 EF 3.3- 5.6, for photos of insects. Canon do a 12 and a 25mm; Kenko do a set: 12, 20 and 36mm. Any thoughts as to which size would be of greatest use to me? TIA
