Generally speaking, it’s not enough to be problematic for average printing or web sizes, being really only particularly visible when examining an image at 100%. The Sigma 18-200mm f/3.5-6.3 DC Macro OS HSM lens shows a good resistance to chromatic aberrations, but it’s possible to see it occurring in some high contrast areas of images. A false confirmation of focus is very rare, while in very dark conditions it may struggle to lock on at all. The Sigma 18-200mm f/3.5-6.3 DC Macro OS HSM lens is good at focusing in a variety of different conditions, but in less than bright light, it can take a little while to acquire focus - especially at the telephoto end of the lens.

Side of the Sigma 18-200mm f/3.5-6.3 DC Macro OS HSM lens Focal RangeĪt 18mm you get an angle of view of 76.5 degrees.Īt the full zoom of 200mm, the angle of view is 8.1 degrees. You can switch it around to face the wrong way when storing the lens or camera with lens attached. The lens barrel features macro magnification markings, so you’ll be able to see what magnification you’re getting at different focal lengths.Ī lens hood is supplied in the box which you can attach by lining up the markings on the lens. As you zoom the lens, you’ll see the front part of the lens extend, but it does not twist making it suitable for use with filters.
