# Question: Is 1.4 Or 1.8 Lens Better?

## What does 1.8 mean on a lens?

So if we say a lens is f/1.8, that means that the biggest opening we can get is equal to the focal length of the lens divided by 1.8.

You may well have noted that the maximum opening of the lens, the specifying f/number, is often not one of the numbers on the regular sequence of 1, 1.4, 2, 2.8, 4..

## What does the F 1.4 mean?

Simply put, the f-stop number is tied to aperture. The higher the f-stop number, the smaller the aperture, which means the less light enters the camera. … So, f/1.4 means the aperture is pretty much all the way open, and lots of light is entering the camera.

## What makes a good lens?

2) Speed. The camera lens is responsible for capturing and focusing light onto the camera sensor. Better quality lenses tend to have a larger aperture, allowing more light to pass through to the sensor. The aperture size is measured as an f-stop.

## What does f/2.0 aperture mean?

An f-number of 2, expressed typically as f/2, means the focal length is twice the size of the aperture; f/4 would be a focal length 4 times the aperture, and so forth. … f/2.4 is a half stop less than f/2.0, therefore an f/2.0 lens transmits 50% more light to the sensor.

## What should my f stop be set at?

These are the main aperture “stops,” but most cameras and lenses today let you set some values in between, such as f/1.8 or f/3.5. Usually, the sharpest f-stop on a lens will occur somewhere in the middle of this range — f/4, f/5.6, or f/8.

## Which aperture is best?

A faster lens, such as the 14-24mm f/2.8, has a sweet spot between f/5.6 and f/8. Since the majority of professional lenses have a widest aperture of either f/2.8 or f/4, you’ll often hear that the best aperture is either f/8 or f/11.

## Which aperture is better for a mobile camera?

Smaller f/2.4 apertures do perform good on bigger sensor cameras(ex: Nokia 808, has a f/2.4 lens on a huge 1/1.2″ sensor, and it performs the best even on night shots). Answering your question, at least for a capable sensor, f/1.8 is best. Wider the aperture, better the expectancy of a good shot.

## When would you use a 1.4 aperture?

If you’re sufficiently far away from your subject, then using f/1.4 would result the majority of your subject being in focus. If you have a high performance AF system (something like the 7D perhaps), then you’re more likely to keep the point of focus exactly where you expect.

## Is the 50mm 1.8 worth it?

The 50mm f/1.8 lens is a decent lens from an optical perspective. It has good sharpness, and honestly can’t be beat for its price. It should be noted, however, that it has a very cheap, fully plastic body. … Might be worth the extra cost to have a more durable lens.

## Why are low aperture lenses so expensive?

The aperture is the light opening. … However the larger aperture comes at a high cost. The glass has to be a much larger diameter, 1.4 times larger in diameter to get twice the light passing opening. That means the glass is larger, and thicker, the barrel of the lens larger and heavier.

## Which aperture is best for low light?

In low light, you’ll want to aim for smaller f-stop numbers like f/4. If you plan to do a lot of low light photography, consider purchasing a lens known for having a wide maximum aperture. Some of these numbers go as low as f/1.4 and f/2.0.

## What does the F stop on a lens mean?

(Focal-STOP) The f-stop is the “aperture” opening of a camera lens, which allows light to come in. It also determines how much is in focus in front of and behind the subject (see depth of field).

## Is Canon 50mm 1.8 good for landscape?

It will have the same field of view as an 80mm lens. … So, most landscape photographers use wide-angle lenses (ones that have a focal length less than 50mm). You can still get good compositions from the 50mm lens however, you’ll just need to be a bit further away to fit everything in.

## What is a 50mm 1.8 lens good for?

Why You Need a 50mm Lens: They’re Great for Low-Light Shooting. If you really want to expand your photographic capabilities, a 50mm lens will allow you to do so because they’re great for taking photos when lighting is low. With maximum apertures of f/2 and larger, 50mm lenses can collect a lot of light.

## What is the difference between F stop and aperture?

Aperture (f/stop) is the size of the opening inside your lens through which light passes. … The “aperture” is the diameter of the entrance pupil of the lens, and is measures in mm. The “f-stop” is the ratio of the focal length and the aperture diameter: f-stop = focal length / aperture diameter.

## Is 1.8 or 2.2 aperture better?

1.8 lets in more light compared to 2.2, but that doesn’t necessarily mean it’s better. Also, aperture is not a factor of a camera, it’s a characteristics of the lens. The lower number actually means a bigger aperture and vice versa.

## Is the Nikon 50mm 1.4 worth the extra money?

The 1.4 is quite a bit sharper than the 1.8 as well. If you shoot them side by side, you would easily be able to tell the difference in sharpness at the same aperture. … There is an even more expensive model of the 50mm with an aperture of 1.2, but if you are not a full-time pro, I don’t think its worth the price.

## Why are 50mm lenses so cheap?

The 50mm lies in the sweet spot. … (Note that there is a reason why even the 50mm gets much more expensive as you get faster than f/1.8.) That makes it intrinsically cheap, and it helps, of course, that the lens body is usually of a somewhat lower quality than the more expensive lenses (particularly in Canon’s case).
