Where is a lens sharpest?
Generally speaking, for almost every lens, you'll get a sharper image―with all other factors being equal―at the middle apertures and not at its widest or smallest aperture.
The sharpest aperture is when the overall image is at its sharpest. The sharpest aperture of your lens, known as the sweet spot, is located two to three f/stops from the widest aperture. Therefore, the sharpest aperture on my 16-35mm f/4 is between f/8 and f/11.
We'll look at exactly how to test your own specific lenses below, but as a general rule of thumb, your lens' sweet spot will be between two to three full 'stops' down from the lens' maximum aperture. So, for example, my own Canon 50mm f1. 4 lens' sweet spot will be around f2 – f4.
You should set your lens' aperture to be between two and three full stops smaller than its widest possible aperture. Getting here is like hitting the "sweet spot." For my Canon 50mm f/1.4 lens, the sweet spot is between f/2 and f/4. Lenses with a maximum aperture of f2. 8 will have an aperture range of f4 to f5.
The thumb rule of calculating the sweet spot of a particular lens is to find out the middle range aperture values. E.g. the aperture values of Canon 50mm f/1.8 ranges between f/1.8 and f/22, therefore, that sweet spot of the Canon 50mm f/1.8 lens is somewhere between f/5.6 to f/8.
MTF (resolution) Classic 50mm primes tend to be rather soft at max. aperture setting but they get extremely sharp when stopped down to around f/4 or at least f/5.6. This is mostly true for EF 50mm f/1.8 STM as well.
If you're shooting flat subjects, the sharpest aperture is usually f/8. My lens reviews give the best apertures for each lens, but it is almost always f/8 if you need no depth of field.
Most lens makers' sharpest lenses are their 300mm f/2.8, 400mm f/2.8, 500mm f/4 and 600mm f/4 ED and L series lenses. Look at their MTF graphs, and they really do have virtually perfect performance. Unfortunately, long lenses have even more stacked between them and a sharp picture.
Lenses with a aperture are often extremely sharp when they are stopped down a few stops, or at whichever aperture is optimal for the lens, such as f/4, f/5.6, or f/8.
Generally speaking, the best focal length for portraits is 85mm. It's a flattering focal length because it doesn't distort the subject's facial features. You can use a 50mm lens on a crop-factor lens to get a similar effect.
Which lens gives sharp images?
I am a huge advocate for using manual focus lenses to capture sharp images. With a manual lens, you can fine tune your focus directly onto what you want to be the sharpest point of your image.
As such, the question of which focal length is most cinematic is essentially subjective. That said, 28mm lenses are often cited as the most used in cinema history. Offering a view a little wider than the average person's field of vision, the 28mm lens emulates a sense of reality in the viewer.
The 500 Rule
The equation divides 500 by the focal length of your lens. For example, with a 50mm focal length, you'll have 10 seconds before the stars move (500 divided by 50 equals 10). With a 24mm focal length, you'll have 40 seconds before the stars move.
It's one of the most popular lenses on the market, and it can be used for anything from portraits and car photography to landscapes and nighttime shots. The only time you can't use a 50mm lens is when you're so far away from your subject that capturing it requires a telephoto lens.
A 50mm lens has 46 degrees angle of view. The center of our field of vision, around 40-60 degrees, is where we get most of the information. This means that our perception depends on this part. It is close to the 50mm angle of view.
And aperture doesn't just affect light — it also affects depth of field. The lower the f-stop, the less depth of field and the blurrier the background. Increase the f-stop, and you'll get a greater depth of field and sharper background as a result.
One of the factors that affect sharpness is the aperture value used to take an image. Wider apertures have less area in focus. As the aperture is narrowed down, the sharpness gradually increases, and after a certain point, the image again starts getting softer.
Sharpness at maximum aperture is excellent across the board (just a slight decrease in sharpness around 30 mm), and the "sweet spot" for sharpness is unusually broad, with truly excellent results from f/5.6 to f/8 at all focal lengths.
To get everything in focus, you will need to narrow your aperture and use a technique called "deep focus". Most professional photographers will recommend using f/11 as a rule-of-thumb. This should effectively ensure that the elements from the middle ground to the background of your image remain in focus.
It's commonly used for landscape photography. Less light also means a slower shutter speed. Because of this effect, it's best to use f22 for certain types of subjects: Scenes with adequate lighting.
Why are my wildlife photos not sharp?
Keep the shutter speed as fast. Accurate focus and fast shutter speeds are the keys for producing sharp images. An old guideline for shooting handheld is to use a shutter speed equivalent to 1/focal length for sharp images.
Indeed, they have a “sweet spot” – an aperture setting where the best sharpness is achieved. As a rule-of-thumb, this is 2 f-stops (or steps) above the maximum available aperture value. So, if the lens you're using offers a maximum of f/5.6, then jumping two f-stops to f/11 (skipping f/8), will give sharp photos.
One lens in particular—the 50-mm lens—is often seen as the most objective of objectifs, and it is said to be the lens that best approximates human visual perspective.
Final answer: The region where the image is sharpest is known as the fovea.

A fast lens has a particularly wide maximum aperture which can let more light onto the sensor or film than a lens with a physically narrower maximum aperture. With a fast lens you can produce exceptionally shallow depth of field and sharp photos, under low light conditions, without a tripod.
But you might need to carry several prime lenses to cover your needs. Canon fixed focal length lenses are usually sharper than their zoom counterparts - especially in the corners, and much sharper in the non-L lenses.
In photography, we strive to take “sharp” photos. Generally, this means that you want the subject to be in focus with clear lines, crisp details, and no (unintended) blurring. It's a combination of accurate focus, a static camera, and the properties of the lens you're using.
Instead consider the image viewed at the print or display size you intend to use it at. If it's sharp enough like that, then it's sharp. Nothing else matters. To judge sharpness it is necessary to view it "at the print or display size", and with a 100% crop.
Warm colours like hazel, brown or two-toned violet give a naturally sexy and mysterious look. However, if you want to turn heads and get all the right attention go for shades like grey, moss green or earthy browns.
Which is the most comfortable lens?
Lenses made from newer silicone hydrogel materials tend to be more comfortable. They allow more oxygen to pass through to the cornea and take less time to adapt to, as well as being comfortable for longer. Switching to daily disposable or silicone hydrogel lenses could significantly reduce any discomfort.
50mm lenses are good for full-length and waist-length portrait photos, both on location and in the studio. They have a wide field of view, which allows you to stand close to your subject while capturing more of their body and background.
Here is a basic definition of sharpness in photography: sharpness is how clearly detail is rendered in a photograph. That's it! Sharpness is impacted by camera resolution, lens acutance, and more. But the sharpness of an image is simply a matter of detail in the final photograph.
Dan Laustsen, ASC, DFF says that his goal with "John Wick: Chapter 4" was to boost the energy level in every way, seeking a look that was "bigger, crazier, and more beautiful." That philosophy led him to the ARRI ALEXA Mini LF and ALFA anamorphic lenses.
The 80mm equivalent represents Ansel Adams using the 150mm lens on his Hasselblad. That camera/lens combination was Ansel's go-to setup for portraits, but rarely employed for landscape work. The remainder of his work, his landscape photography was shot almost exclusively with the 35mm focal length.
The four main things that you need to consider (starting with highest important factor) before you buy a lens are aperture, focal length, lens mount type and finally, vibration reduction and auto focus.
As you build your confidence as a photographer at least one prime lens should be in your camera bag. I think the 50mm prime lens is the obvious choice. As you can see the background is still distinguishable and is quite distracting. This is the best-case scenario at about 1.5 ft distance from the subject.
If you mean: as a subject, then the answer is lens-independent. Stay at least 1.5 m away from the camera, if you want your face and proportions look good, and assuming that the body parts are not at very different distances (e.g.: avoid stretching an arm or leg towards, or away from, the camera).
All lenses can see up to infinity. If you want to see how large are it covers then that is the relation between the focal length and the sensor size. On a full frame sensor 600 mm lens covers 3.6 meters horizontally at 60 meters. On an APS-C sensor it covers only about 2.3 meters.
Compare images taken with both lenses from the same position and with the same settings. You would see that the 50mm gives you a shallower depth of field and better bokeh. The 35mm, on the other hand, will fit more into the frame. So it's more suitable for landscapes and indoor photography.
Which lens is better than 50mm?
Arguably a shade more versatile than the 50mm, the 35mm prime is a classic walkaround lens that can adapt to a wide range of shooting situations. (See also: What are the benefits of a prime lens?)
50mm lenses don't zoom
Like mentioned above, a 50mm lens is a single focal length prime lens. This means one thing about the focal length: it cannot zoom in and out to change the lens length.
RESOLUTION & DETAIL. Most current digital cameras have 5-20 megapixels, which is often cited as falling far short of our own visual system. This is based on the fact that at 20/20 vision, the human eye is able to resolve the equivalent of a 52 megapixel camera (assuming a 60° angle of view).
The simplest answer is that the 50mm focal length is equivalent to 'what our eyes see'. It can easily be used to capture a range of angles including overhead, straight on and 45-degree without experiencing too much perspective distortion. It's also a lens that is suitable for a range of different niches.
50mm lenses are ideal for full-length and waist-level portraiture and can be utilised on location or in a studio. The lens' larger field of view compared to that of an 85mm or 135mm focal length means that you don't have to position yourself as far from the subject to get these crops.
One of the factors that affect sharpness is the aperture value used to take an image. Wider apertures have less area in focus. As the aperture is narrowed down, the sharpness gradually increases, and after a certain point, the image again starts getting softer. This is due to a phenomenon of light called diffraction.
Aperture and image sharpness are closely related. Wide apertures and sharpness: When we use wide apertures, the depth of field drastically decreases. This means that just a very small area of our image will be acceptably sharp.

Two fundamental factors contribute to the perceived sharpness of an image: resolution and acutance. Acutance describes how quickly image information transitions at an edge, and so high acutance results in sharp transitions and detail with clearly defined borders.
Depending on what TV you have, you should set your sharpness to 0% or anything under 50%. If you notice a halo appearing around objects or if the image is too grainy, your sharpness setting might be too high. You will also notice that motion looks more natural when your sharpness settings are correct.
What is the sweet spot in photography?
So, What Is The Sweet Spot? The sweet spot, by the way, is the aperture at which your lens will give you maximum sharpness. It's actually fairly simple to calculate your lens' sweet spot. As a general rule of thumb, your lens' sweet spot will be between two to three full stops down from the lens' maximum aperture.
The general rule of aperture is that the larger the opening (that's the size of the opening of the diaphragm in the lens), the more light you take in. In relation, the smaller the opening, the less light you take in.
The pupil can be as large as 6–7 mm wide open, which translates into the maximum physical aperture. The f-number of the human eye varies from about f/8.3 in a very brightly lit place to about f/2.1 in the dark.
Whereas Strand's images were flat (by design), Adams's were all about ultra-sharp depth of field (the appellation f/64 was an optical reference to the aperture setting (f/64) that produced the finest picture detail).
A large aperture results in a large amount of foreground and background blur. This yields a shallow depth of field, AKA a shallow focus effect. On the other hand, a small aperture results in a wide depth of field that can give you a sharp foreground and background for landscape photography.
