I have always found the kit eyepiece on the EOS 300D to be uncomfortable to use; I have to angle my face just so I can press my eye as close to the viewfinder as I can. The EP-EX15 Eyepiece Extender remedies this problem by adding an ergonomical 15mm of space between the viewfinder and the eye.
The EP-EX15 is available at most stores around the Peninsular Plaza area for between S$30 – $38, and is compatible with the EOS-1D/1v/3, 5D, D30, D60, 20D, 30D, 300D, 350D, IX Lite, and Rebel 2000/G/GII/K2/T2/Ti/XS bodies.
Update: Since I’ve switched to an EOS 30D—which has a bigger viewfinder—I have concluded that the EP-EX15 is not worth the 30% image reduction it causes. More about that in a separate article here.

I love this addition to my camera bag! Works get with my 70 – 200 zoom. I only wish it would work with more lenses.
