"Aperture is incredibly easy: if you use a smaller F number, you get a smaller depth of field; if you use a larger F number, you get a larger depth of field."
"Aperture determines the depth of field in your photo."
"Master your aperture... start composing perfect photos at F/2 or less."
"To manually switch the aperture, go to the pro mode of your camera."
"You just open that aperture to F1.2 and you are just going to completely obliterate that background."
"Almost all of them start off in aperture priority mode. This is where you should begin to learn."
"If you increase your aperture, you will generate depth of field."
"The 50 f/1 is great because that f/1 is crazy, even the arm right here is out of focus."
"Just because your prime goes down to f 1.4 doesn't mean that every photo you take should be at the aperture."
"Utilize all the other aperture values because they are there for a reason."
"I don't usually use zooms because they can't go as low as F2...it was a real pleasure to have something that can retain such a good aperture for my kind of work."
"We are an aperture through which the universe is exploring itself."
"Aperture is how wide the lens is opening."
"The heart of the matter with aperture priority mode is that we change the aperture and the camera changes the shutter speed for us."
"In terms of where they are, somewhere between f5.6 and f11 normally gives you a pretty sharp image."
"...for many photographers f6.3 feels like it crosses some sort of a go/ nogo Threshold..."
"Now, the bigger the hole, the more light that is sent to your camera. And the smaller the hole, the less light that travels to your camera."
"So, f/2.8 is a larger hole compared to f/16. How is that possible? Well, there's some math involved."
"An image shot at f-22 will never be as sharp as an image shot at f11."
"Wider apertures make for smoother blurrier backgrounds."
"Large aperture lenses like this 50 millimeter F 1.4 lens are often prized by photographers."
"If you prefer using your camera in Auto most of the time, then I don't actually think the variable aperture is going to be that much use to you."
"Aperture priority mode allows you to change the aperture."
"I am using wider f-stops now in my bird photography."
"I rather have the ability to shoot at F22 or 2.5 then be locked into 2.8 all the time."
"Look at the difference between wide open, this is 1.4, versus F2."
"Since we want more light on our sensor, you're probably thinking great, let's use the largest opening possible like an f 2.8, but you'd be wrong."
"The aperture or the iris is the hole in the lens. The lens hole is called the aperture or the iris."
"It opens up the aperture all the way so you get this nice blurry background."
"The aperture being able to have F 2.8 all the way through at this focal length as I've already talked about is amazing."
"The aperture is how big the opening is in the back of the lens that allows the light into your camera."
"Wow, the middle is really sharp at f11."
"The lower the f-stop number is, the bigger your aperture is and the more blurred out your background's going to be."
"Obviously a lot of people might say that a prime lens is going to be better because it offers you an F 1.8 aperture."
"Both lenses are equally as sharp at F 5.6, they are identical."
"For wildlife, for the sharpest possible images, I would recommend using an aperture between 7.1 and 9."
"It's flawless at F2, like just pure, pure, pure perfection."
"The aperture is literally how large the hole in the lens is going to be or how much light a lens is going to let through to touch the strip of film or the digital sensor."
"F2 really is a sweet spot for vintage lenses."
"Use a really narrow aperture, and that basically solves the depth of field problem."
"You get the beautiful soft background that you get from the wide apertures but still have enough depth of field."
"Aperture priority mode is the mode that I want you to learn your camera on as soon as you're willing to take the jump."
"It's almost like it does behave like a 58 2.0 except it's a 1.2, so you have narrow depth of field."
"The ability to shoot in almost no light just stopped down to 1.7."
"Now you are ready for aperture mode. This is going to be your new favorite mode."
"F11 is the fine balance between extended depth of field and really sharp image quality and texture."
"I've come down to f 3.5, ridiculous."
"Power's not important, aperture's important."
"Aperture is a mechanical device which changes the size of the hole behind the lens."
"Choosing a lower f-stop number decreases the background sharpness, a higher f-stop number increases the background sharpness."
"This lens is super sharp wide open and it has a maximum aperture of 1.8 which is great for giving your portraits that background separation."
"When you are using a very wide aperture like f/2 in a blurry background, this is definitely the way to go."
"Sony decided to put a ring on it, an aperture ring, ah, while maintaining that sweet, sweet G-money quality."
"The smaller the f-number, the larger the opening, the more light that will get in and the brighter your image will be."
"Most photographers will be more than happy with the corner sharpness and overall sharpness at F16 on a full-frame camera."
"Try F16 and just see whether that is sharp enough for you as a photographer."
"My aperture set for the shallowest depth of field to make sure that all the stuff back here is all beautiful bokeh licious."
"They're very sharp because they don't open up to any more than F 3.5, so they've got that inherent sharpness."
"The most common use of wide apertures is to clearly draw attention to the thing that you as the photographer want the viewer to pay attention to."
"This is the D Jupiter 8, it's an F2 lens, so it's quite fast."
"The widest aperture that your lens has will be the one that gives you the most separation."
"This is pretty incredible, f 1.8 guys."
"The field stop is the aperture in the system that limits the field of view."
"You want it to be wide but also want it to be really sharp and fast aperture."
"It's really nice because it means that we can shoot wider open lenses."
"The lowest aperture available is also 1.7, and that's a true 1.7 without the crop."
"A smaller F number is a big opening that lets in more light, and a larger F number is a small opening that lets in less light."
"Aperture priority... you set the aperture for your camera, and it selects the shutter speed based on the available light conditions."
"Another great thing about a prime lens is that it has a really low aperture in most cases, this gives you a more shallow depth of field, giving you that nice soft dreamy background, beautiful bokeh."
"Now although the lens has only a three-time zoom, it makes up for it by providing an aperture availability of 1.7 to 2.8."
"The lower the f-stop, the more light is going to be allowed in through that lens and collected by the image sensor."
"Smaller numbers like f 1.4 and F 2.8 are considered to be faster lenses because they allow a lot of light into the camera."
"This lens can open up all the way to F2, which can definitely create some of that background blur that the bokeh-hungry filmmakers among us are really going to appreciate."
"Every time we double our aperture size, we quadruple the light that we gather."
"Shoot above a 2.0 but below a 4.0 because that's going to give you the ideal level of sharpness for the artist."
"From F 2.0 on a full wide open aperture all the way down to F22, I've been so impressed by the image quality."
"The standout benefit of the 85 1.2 is of course its much brighter aperture and opportunities for shallower depth of field effects."
"Don't let that 5.6 aperture fool you because this thing puts out some serious blurred background or some bokeh."
"Usually two stops closed is the sharpest part of your lenses."
"A low f-stop means that the aperture is more open, and more light will reach the sensor."
"Depth of field has many contributing factors such as the aperture, your distance from the subject, and also the focal length of the lens you're using."
"What good means is very, very, very sharp at all apertures, with a nice soft background blur."
"It's an f2 80 millimeter lens for medium format, so f2, you're going to get insanely shallow depth of field."
"The aperture of a camera is the equivalent of the pupil in a human eye."
"The large aperture lets in more light and allows you to shoot at faster shutter speeds."
"The aperture will be set wide open in portrait mode, meaning the lens will let all the light into the shutter that it can."
"In landscape mode, the aperture will have a very narrow opening, creating a very long depth of field."
"When you open up your aperture you get more light, but also a shallower depth of field."
"It's got a quite a wide maximum aperture which means that it's going to do well in certain situations where the light isn't so good."
"Aperture is one piece of the exposure triangle, so it has an effect on how bright or how dark our images are."
"With that max aperture of F1.7, you're able to get some really nice looking depth of field."
"It's nice, it's fast, and we can open that aperture up to blur out the background."
"Having a lower aperture prime lens for this sort of photo shoot is really handy."
"It has great contrast, well corrected even at f 1.4 but also manages to have really creamy soft bokeh."
"Aperture controls the depth of field."
"If you've ever seen photos with dreamy, blurry, out-of-focus backgrounds, aperture is probably the reason why."
"This is an absolutely great lens if you're looking for an affordable 50mm with a really fast aperture of 1.4."
"Lenses that are good in low light will have a wide maximum aperture which also provides us with that shallow depth of field and nicely separates the subject from the background."
"The larger apertures give you the same depth of field, so if you're used to shooting at f11 with your full-frame cameras, the equivalent aperture is about F 5.6 for Micro Four Thirds."
"All seven of the make a lenses are usably sharp at t 2.2 and are tack sharp by t4."
"The aperture will govern the amount of sharpness in the picture from the foreground to the background and we call that depth of field."
"The killer feature of this lens is the maximum aperture of f/1.2."
"With an F1.4 aperture, we can also isolate foreground detail from the background."
"I shoot in aperture priority so I can control the lens aperture and the depth of field."
"It's just so fantastic wide open that there's not a lot of room for improvement even when stopped down."
"You have the ability to shoot all the way down to 1.7 and blur the background out."
"Aperture is the diameter of the lens opening. This affects the exposure by controlling how much light is allowed through the lens."
"That f 1.2 aperture allows you to shoot at f 1.2 as a portrait photographer and get fabulous results."
"This is a lens which is packed with character, it gives awesome flare, and I really enjoyed shooting at such wide apertures."
"It has a 1.4 aperture, which is going to give you that excellent performance in bright light, that blurry background if you want it, and just that overall professional and more cinematic look."
"The beauty of this lens is its F 1.8, so although I've shot this at f/4 so that I have enough depth of field, I'm able to do my focusing at F 1.8 extremely precisely when it is very dim after sunset light."
"A superb Fujinon lens with a widest aperture of F2 at the 28mm wide-angle end of the zoom."
"Stop it down to f2.8 and it really comes alive."
"Shooting at F 1.4 offers a very shallow depth of field and very pleasant natural bokeh."
"The bigger the aperture, the smaller the angle that you can resolve two distinct points."
"It's not your typical lens; it's super fast, it's a super bright f2.0 at wide angle and 2.8 on the Telly end."
"So now you've opened up your lens, and you have this aperture ring here."
"The Sigma lens has an f-stop of 1.4 which is great for creating shallow depth of field but also creating good low light capabilities."
"The arguments about using a wide aperture such as F 2.8 to give you a shallow depth of field only really applies when you're using a telephoto lens."
"The lens aperture diaphragm has nine blades which results in a super buttery out-of-focus area."
"A lower f-number means a wider aperture. This lets in more light and improves clarity."
"What you want for a blurry background is you want a low f-stop."
