2. EFS 55-250mm f/4-5.6 IS II CANON LENS

This telephoto zoom lens is designed with Canon’s Optical Image Stabilizer technology while retaining compactness and lightness, in response to demands of photographers. This high zoom ratio lens is equivalent to a focal length of 88-400mm in the 35mm format (when used on Canon EOS cameras compatible with EF-S lenses), and the image stabilizer effect equivalent to a shutter speed about 4 stops faster than the same size lens without Image Stabilizer. In other words, if the slowest shutter speed you could formerly hold a 250mm lens steadily was 1/250th of a second, with Canon’s 4-stop stabilization correction, you could hand-hold at shutter speeds as slow as 1/15th of a second. It also uses a UD-glass lens element to correct chromatic aberration for excellent image quality throughout the zoom range. This new EF-S telephoto lens with great features delivers excellent performance at an affordable price for all photographers.

Focal Length & Maximum Aperture 55-250mm f/4-5.6
Lens Construction 12 elements in 10 groups, including one UD-glass element
Diagonal Angle of View 27° 50′- 6° 15′ (with APS-C image sensors)
Focus Adjustment DC motor, gear-driven (front focusing design)
Closest Focusing Distance 3.6 ft./1.1m (maximum close-up magnification 0.31x)
Filter Size 58mm
Max. Diameter x Length, Weight 2.8 in. x 4.3 in./70 x 108mm (maximum lens length); 13.8 oz./390g

well then.. kedua barang tersebut punya harga masing2 berkisar di 2,5 jt.. so.. ayo menabung.. wkwkwkwkwkw..

  1. Telenya klo buat dikondangan kurang mantep keknya Ry..
    Bukaannya kurang gede..

    Ngga cari yg fix dulu?
    Biasanya Canoners cari yg 50mm f1.8 buat secon lensnya..
    800rb-an udh bisa pulang yg baru..
