What Are Extension Tubes?
Extension tubes usually comes with a range from 10mm to 16mm. The point is to give a gap between your stock lens and the body sensor. It is hollow inside, and hopefully has sensors that allow autofocus information to pass through.
As physics has it, this allows you to shoot closer, thus making the lens “macro”. The more you can extend, the closer you can get to the subject. But at a cost. There’s a maximum length (10mm + 16mm = 26mm) for usability. Image quality drops. And the inability to focus to infinity, this means you no longer can shoot portraits or landscape till you detach the extension tubes.
Third party adapters are way cheaper than originals, this Meike brand was bought for only RM90 when Fujifilm’s originals will cost about RM500.
Extension tubes seems to be limiting on a macro photography level. Lost of image quality & inability to focus to infinity.
Is there still any use for extension tubes? Yes there is. It can still convert your non-macro lens (ie Fujifilm 90mm f/2) into a one.
