Canon EF 70-300mm f4-5.6L IS USM prism it's enoughYes, the Canon EF 70 300mm f4 5. 6L IS USM is specced exactly like the non L version: same aperture range, same focal lengths. But it's a substantially better lens inside, with a different optical design, quick autofocus performance, true L series build quality, and a great stabilizer. This lens is in excellent condition overall, with very minor paint wear, clean glass, and solid performance throughout. Includes original hood.
