Rather than playing on the difference
in focal length like the iPhone 7 Plus, here the point is that there's one color sensor and one monochrome sensor, which combine to create more detailed images.
The much larger field of view makes this perfect for capturing landscape and group shots, but the lack of difference
in focal length means you don't get the depth of field bokeh effects that other dual - camera devices offer.
Confusingly, however, there's no difference
in focal length between the two lenses - i.e. they both have the same view onto the world and are present for depth detection for portrait shots.
The P20 Pro comes with two claims to zoom fame — the difference
in focal length means it offers 3x Optical Zoom, but the 5x Hybrid Zoom works almost as well as the optical zoom.

in focal length, and some people with glasses may find it difficult to adjust vision to it.
Not exact matches

in doubt, choose a telescope with both a large aperture and
focal length.
To solve this problem, the Columbia Engineering team developed an adaptive lens array made of elastic material that enables the
focal length of each lens
in the sheet camera to vary with the local curvature of the sheet
in a way that mitigates aliasing
in the captured images.

in orbit to construct a single telescope with a
focal length as large as the distance between them.
There's but one fact on the Hubble Telescope's optics which must be kept
in mind: The Hubble telescope has a very long
focal length of 190 feet (58 m), and thus a one degree field measures one full meter
in the space telescope's
focal plane, and one arc minute about 1.7 cm.
Following [20], two main regions were defined for each perspective, by dividing the control volume into: i) the region of fish - robot interaction (referred to as the «
focal region»), which extended eight fish body
lengths and was centered on the robotic fish center of mass, and ii) the non-interaction zone, which consisted of the remaining portion and was delimited by the two plastic honeycombs, that is, the front-most and back-most regions, respectively, shown
in Figure 4.
In the Top view, the focal region was further divided in two equal sub-regions: i) frontal compartment (referred to as «front») comprising the half of the focal region in front of the robotic fish and ii) four equal compartments of one body length each (referred to as «B1», «B2», «B3», and «B4», respectively) behind the robot, see Figure

This approach avoids the need to grind and polish many individual segments to the same shape and
focal length, thus potentially leading to significant savings
in schedule and cost.
The second pair of cameras, fixed -
focal length Mast Cameras (Mastcams) with a 34 mm and 100 mm
focal length, were delivered
in March 2010.
In rare cases, a non — length dependent neuropathy results in symptoms involving the trunk, face, proximal limbs, or other focal areas [2 •, 3 •

length skirt be the
focal point with minimal accessories (just a matching lip, nude pumps and gold clutch) at a dinner hosted by Harper's Bazaar
in N.Y.C.
The camera's
focal length isn't as wide as some of the systems we've used
in the past, so you'll have to use the sideview mirrors to see things at the extreme corners of the car.
Primary one is of 13MP and comes with F / 2.0 Aperture, 26 mm
focal length, 80 - degree wide angle lens, PDAF (
in 0.03 seconds) etc..
It has a very shallow
focal length (which makes for some cool unintentional bokeh effects) and a tendency toward both noise and blurriness
in anything but the best possible lighting.
In addition,
focal syrinx cavities can form anywhere along the
length of the spinal cord if there is something near the syrinx causing turbulent CSF flow.
You can use every
focal length of lens you have to make Haystack a smaller element
in a grand landscape or zoom
in to frame it tightly.
By investing
in a range of lenses you can produce images
in a range of scenarios — architecture, interiors, even wildlife — that would be more difficult with the limited range of
focal lengths available with the standard kit lens.
The images were shot from a light aircraft flying at between 4,000 & 5,000 ft.. The height was crucial
in order to flatten perspective by using long
focal lengths.
In our camera comparison, we found that the main difference between the two is the wider overall focal length in both of the cameras, more noticeable in the front facing camera

That means you are just cropping
in and getting a lower resolution final image, instead of using the lens with double the
focal length.
There are some caveats
in this test, of course: With different
focal lengths and apertures (2.87 and ƒ / 2.2 for the front - facing camera, vs. 6 and ƒ / 2.4 for the rear - facing) framing the exact picture was often tricky;
in addition, the ISP was much more reticent to create a depth map for non-human subjects on the front - facing camera — I often had to shoot significantly wider on the front - facing camera to get it to enable Portrait mode.
In the camera module, a 16 Mp image sensor is coupled with a f / 2.2 aperture lens that provides an equivalent
focal length of 31 mm.

For other enthusiasts, there's Pro Mode, which not only allows manually changing ISO, exposure compensation,
focal length, white balance, contrast, saturation, temperature, tint, highlights, and shadows, but also shows all these effects
in real - time, so that you could know how the final image would turn out to be.
Aside from the main cameras compared here, let's also remember that the OnePlus 5 packs a complete secondary camera that offers a longer
focal length for interesting shots and a Portrait Mode that gives you unique background blurring
in certain photos.
The idea here is to create pictures that look more like they're from a DSLR professional camera with a shallow depth of field, making the foreground subject «pop»
in a way that it can't with the normal
focal lengths of a smartphone camera.
For those who don't know their way around these terms,
in short explanation, f - number is a ratio between the

A lens with a shorter
focal length will require you to put more distance between your subject and background
in order to throw that background out of focus and get some bokeh happening.
In terms of field of view, a wide angle lens with a
focal length of 14 mm on a full frame or 10 - 12 mm on a crop frame should be sufficient.
