If you want to use an all-in-one lens and want to maximize sharpness, I recommend staying away from the wide-angle and telephoto extremes of the focal length (dial it back a bit) and shoot at mid-range apertures around f/8.
#WHY DOES ZOOM NOT NEED SPEED CANNON PRO#
Many all-in-one lenses are relatively sharp-and today’s zooms are much sharper than zooms of yesteryear, but no all-in-one zoom is going to compete against a nice prime lens, or a wide-aperture pro zoom, for ultimate sharpness. As a counter to this drawback, might I humbly suggest being a two-lens photographer and carrying a small, inexpensive, and lightweight “nifty fifty” 50mm lens in your bag for low-light situations? Sharpness Some all-in-one lenses for smaller format sensors have wider apertures-a welcome thing-and many combat the potential of slower shutter speeds with image stabilization. In the world of light, larger apertures are better, but here we are sacrificing light-gathering power in the name of convenience. Most all-in-one lenses have relatively small maximum apertures of f/3.5 or smaller. Even with larger all-in-one lenses, when you consider all the lenses that this one lens might virtually replace in your camera bag, the size/weight argument is handily won by the all-in-one lens. Most all-in-one lenses are lightweight and fairly compact, especially when compared to telephoto lenses. This flexibility is, often, a boon to creativity and creative compositions. There is nothing like an all-in-one zoom lens when it comes to recomposing a scene without moving your feet (or swapping lenses). Not switching lenses means you will be less prone to missing fluid compositional moments or dynamic action due to fumbling around in your camera bag looking for a different focal length lens. Have you ever dropped a lens while changing lenses or gotten a bunch of dust on your exposed sensor while swapping glass? I have done both. No need to carry or switch four separate lenses to go from wide to normal to portrait to extreme telephoto.
While it’s smart to protect your gear with a camera bag, a bag designed to carry one camera and a single lens, versus one camera and several lenses, is going to be smaller and lighter-and, if you still carry a bag, leave room for other things like water bottles and walkabout necessities.
One versatile lens weighs less than several less versatile lenses. But, there are pros and cons, so let’s take a quick look at both sides of the all-in-one lens. These days, for interchangeable-lens cameras, we get to enjoy high-ratio zooms that range from 7x to a head-turning 33x zoom range. The superzoom name has been transferred from the SLR all-in-one zoom lens to bridge cameras, like the Nikon P1000.
