EW-83 H or EW-83 D II. The EW-83 H is a replacement hood for 24-105/4 IS. LNIB. Bought it from E-bay for 15$ last week. Mounted it on my 10-22 only once and immediately saw that it has the exact same vignetting characteristics as my current EW-83 D II. The EW-83 H is yours for 5$ with purchase of any of the above products. The EW-83 D II is Canon's original hood (thicker and with inner flocking) and has marks on it. The EW-83 D II is yours for 10$ with purchase of any of the above products.
