I'm looking into getting automatic extension tubes but I went on ebay and one seller says they can't be used with ef-s lens. Does this apply to all extension tubes or just this sellers?

Jessops own brand extension tubes do work with EF-S lenses. Don't know about any others. http://www.flickr.com/photos/lordv/

Yes you could with the lens set around 40-50mm you'd be shooting at over 1:1 magnification but the focus distance from the front of the lens would only be 2 to 3". http://www.flickr.com/photos/lordv/

Brian V. Thanks Brian. I have no problems getting that close, which I can and often do with this lens, but the results, even when focused properly are usually disappointing. The images just lack that extra bit of oomph David: Canon EOS 400D - Canon EF70-300mm f/4-55.6 IS USM -Sigma 17-70 F2.8-4.5 DC Macro - Sigma 50-500 'Bigma' - Speedlite 580EX 11 - Better Beamer

Been shooting with tubes for a while now, had the same issues as you last year, this year armed with a flash the difference is huge...!

Does EF-S only refer to Canon lenses, or is it refering to the mount?? ***I was told there were no stupid questions, so please be gentle on me*** Parm Hi Parm http://www.flickr.com/photos/lordv/

Mar 19, 2007 16:23 | #12 LordV wrote in post #2896571 Hi Parm No the sigma 105 is an EF mount lens. EF-S refers to lenses that only fit on APS-C 1.6 crop digital cameras- they cannot be used on FF cameras (or 1.3 crop cameras). EF-S is canons nomenclature for 1.6 crop only lenses. Sigma use DC as denoting the same (not to be confused with DG) Brian V. Thanks a ton Brian... Canon 60D, Canon 70D
