TIPS ON HOW TO KNOW THE BEST FOCAL LENGTH OF LENS TO BUY

So that you recognize the distinction between zoom and top lenses and how to blur the background, you need to find out the best focal length of lens to shop for your photographing career.

I recommend that you use of a zooming lens in your camera to discover the best focal length to your office, studio, or wherever you are going to shoot and then buy that best focal length of lens.

For instance, let’s assume your digital camera came with an 18mm – 135mm lens. Set your ideally framed shot using the camera you have got plus the zoom lens and then look down at the lens to see what focal length you are using to get it.

The Perfect Mood

Another consideration when selecting the best focal length of lens to buy is the mood every lens can portray. Shooting with a 20mm or 24mm may be too much of a mood, if you are too near the camera. They also can distort the edges of the image.

Essentially you simply want to be careful to avoid using too wide focal length when shooting your videos or they will look like you are watching a black and white TV from the 80s

Crop Sensor or Full Frame?

To make this less confusing for you, the camera you own may at some point change what focal length your lens naturally produces relying on whether or not has a complete frame or crop sensor on it.

For instance, taking the Canon 5D Mark III or 6D as an example. They are cameras having full frame sensors, so whenever you put a 50mm lens on them, the focal length you spot is clearly 50mm.

In case you are making use of a Canon 7D7 or 0D, which are crop sensor cameras, the sensor is usually 1.6 times smaller, so you need to increase the focal length by a product of 1.6. In this case, the 50mm becomes an 80mm lens.

Crop factor in the real sense is an integer and it’s normally in the range of 1.3 to 2.0. This small value range tells you how much smaller the sensor can be when compared to a full frame sensor. The nearer the value is to 1, the less the image cropping will take place.

Now you know what crop factor mean! To find out what your cameras’ crop value is, you should check it up in the manual or online. As a general advice, maximum low end Canon cameras have a crop factor of 1.6. But with Nikon’s DSLRs collections, 1.5 is the crop factor. Take note, this value will vary with different cameras and makers, so make certain to look first,  then you can start calculating. Don’t Assume!

Don’t make the mistake of seeing this crop factor value as irrelevant. The cognizance of the value comes to play when shooting indoors or in close angles, like in a vehicle. If you use lenses without cropping factors, you shooting abilities will be limited except if you are using APS – C sensors.
