The Canon Ef Rubber Frame for Dioptric Lens provides cushioning around the camera's eyepiece, and is especially useful to eyeglass wearers. It is compatible with the Canon Digital Rebel XSi, and film Rebel Ti, T2, T4i, and K2 cameras.
★★★★★ Perfect fit for my Rebel T4i and adds a comfortable cushion around the eyepiece. As an eyeglass wearer, it keeps my glasses from scratching and makes shooting much more comfortable.
