standard lens
By far, the EF 50mm f/1.4 USM standard lens is the easiest to use among the four EF lenses utilized for this field-test with the Extension Tube EF 12. This is because there is no risk of having the front element coming into contact with the subject matter as well as camera shake, as experienced with the EF 100mm f/2.8 Macro lens when the magnification reached 1X and greater. With an extra two stops faster in maximum aperture than the three other EF lenses used here, the EF 50mm lens was able to provide a shutter speed of 1/60 sec. at f/1.4 from its closest focusing distance when the EF 12 was attached.

The extreme magnifications of the cellular phone's number pads here do not allow shake-free shutter speeds to function. This calls for additional light source to be utilized via the Speedlite 540EZ. There is one thing that separates the Macro lens from the other lenses utilized here, at the infinity position with the EF 12 attached, the cellular phone can be captured in full, with ample space of the background as well, rather than close-up magnification experienced with the rest. With the EF 12 attached, you can see that the magnification of the image size is slightly higher than 1X life-size, which is at 1.17X. Does the Extension Tube EF 12 make for a good, alternative investment to using Macro lenses for shooting close-ups with the EF lenses in your possession? This will depend on how often you actually shoot close-up pictures. If close-up photography is really your frequently- shot subjects, then it is worth the investment. Of course, you can also opt for the EF 25 rather than the EF 12 Extension Tube. Text and photos by Philip Chong. Copyright 2000 by Canon Marketing (M) Sdn Bhd << Back to Main . 1 . 2 . 3 . |
