same here Sigma 10-20 Tamron28-80 and Tamron 70-300 and 50mm f1.4 if im out and about but if im off to a motorsports event ill take my 400 f5.6L and 580exII, in the studio i use 2x Elinchrom 1250w strobes and a Bowens 500w strobe with a beauty lamp as back light and 2 x 800w continious redhead halogen lamps (not all at the same time) depends on what im shooting [h=3][/h]
I've just found that if I want a lower aperture (higher number) or just to set the apertureI need to set it at what I want and hold down the depth of field preview button while I take the lens off then fit the macro tubes.Hand little bit of info to know
