I think things will only go up from here! After I Googled the problem, I came to the conclusion that you can not go too small or it doesn't work (I never tried it again with the 14mm).
Will these work with a Sigma 105mm 2.8 Macro lens? I see no reason why not. They work with my Sigma 24-105. Will these work with 67mm? these tubes are placed between the camera and the lens and not in front of the lens.they should work with any Nikon mount compatible lens.keep in mind that if you use short lenses - up to 35mm the focus distance will be really small - you will have to be really close to the subject even when attaching only one ring.if you have an 85mm or longer lenses the focus distance is allot better. all the lenses up to 200 or so will lose the focus to infinity. Has anyone tried to use these tubes with a Canon 5D M3? Hello. I do not see the tubes you're referring to but if they are the Kenko macro tubes, yes and they are wonderful. If the tubes are most any other brands that cost $40 or more, they will usually work fine Do these still work with autofocus? (I have a Nikon D7100) I need autofocus! Yes. But I've only used mine on g series lenses , I think they have linkage to work with d series body driven AF lenses, I just haven't tried them with an older lens.
