Here are more detailed description of the different types of lenses and where they can be used best.


Prime Lens


This type of lens has a single focal length and can’t be adjusted. You can’t zoom in or out with a prime lens.

It allows you to take your time on a certain subject without worrying about the weight of the camera. Also, they can take higher-quality images and they can be used at night or in low light conditions because they have faster apertures.



A superzoom lens has the feature of zooming in or out on the subject. Many people call this a do-it-all lens as it can cover any focal length. Though this lens does not produce the best quality of pictures compared to the prime lens and it has slower apertures, this lens is the perfect one to use in situations where you can’t change lenses because of safety or comfort. You can use it when you travel and do not want to carry a handful of lenses with you.


Ultra Wide


This lens has a focal length of 24mm. It can get a vast subject in a single frame. Close subjects come out even closer and far subjects become more distant. This type of lens is usually used by photographers who take images of landscapes. It can also be used in architecture photography as it gives details to straight lines.




Its focal length can be between 24 and 35 mm and can have varying or fixed aperture. Though it can take images of wide fields, it can also focus well on close proximities. It can enhance distances of the main subject and its background. Just like Ultra Wide angle lens, the wide lens is used for taking photos of landscapes, buildings and a crowd of people. The only difference is that it can also be used for taking interesting portraits.




It usually comes with the camera when you buy it. It takes pictures without distorting much of the images and provides the same peripheral vision as that of the human eye. This is usually used for street photography and for beginners who are not savvy about the different kinds of lenses yet.




This lens has a focal length of 70 mm or even higher and it focuses on specific details or subjects from a distance. It makes far objects appear closer. This lens is popular to wildlife photographers as they do not want to get too close to their subjects. Sports and some portraits also use this lens.




This lens is capable of enhancing tiny subjects and magnifying each detail. They have the excellent sharpness that is perfect for close-up images. You may want to check out a Nikon lens buying guide to know more about the different Nikon products and their specs.

Benefits of Using Water Softeners

Their body and facial skins are also softer and cleaner. That is due to the fact that soft water will not clog the skin pores.

The Role of Plyometrics in Today’s Athletes

Plyometrics is something that should be taken seriously by those athletes who want to improve their speed, agility, stamina, and explosiveness. After all, there is no denying that these days, many athletes have improved their performance because of these plyo exercises. Because the exercises involved in plyo are intense, they make the upper and the lower body really strong by stretching the reflexes and contracting the muscles. Among the many types of this exercise, some of the most common are hops, bounding movements, and vertical jump exercises.


While it is true that jumping is an important skill, it can’t be denied that improving it is no easy task. However, if someone does plyometrics, a person can increase the number of his muscle tissue. Once the number of muscle tissue has increased, a person can move faster in just a matter of weeks. Therefore, people who work on their plyo jumping can perform better in whatever sports they are into, whether it’s basketball, volleyball, mixed martial arts or MMA, or any other sporting activity.

Among the sports mentioned, it’s MMA that’s gaining unprecedented following nowadays. Conor McGregor, Anderson Silva, Jon Jones, Amanda Nunes, Ronda Rousey, and Joanna Jedrzejczyk are just some of the most popular men and women who have made MMA their sport of choice. Also known as “Ultimate Fighting”, MMA is a combat sport that combines elements of boxing, wrestling, and similar sports. A fighter’s main goal is to knock out his opponent by submission until the latter taps out in surrender.


A fighter needs to strike and grapple if he wants to be able to hold or “choke” his opponent to submission. So really, an MMA fighter, especially one who is new to the sport, needs to undergo intense workout to strengthen his core and undergo concentrated MMA training for beginners in order to be good at the sport. Plyometrics, as mentioned earlier, is part of an MMA fighter’s training.

Apart from improving their vertical jump, people who do plyo exercises also improve their flexibility, especially if they use certain equipment. However, it must be remembered that these equipment pieces need not be expensive, especially those that are related to improving the vertical jump.

While there is no questioning that plyometrics deliver the desired results, it must be clear to people who do them to be extra cautious when doing the exercises. It is important for these people to observe the proper way to do these exercises. While it’s true that having a personal trainer or a coach can mean spending some amount of money, hiring the services of one is a good way to avert injuries. 


In the event, though, that one doesn’t have enough financial resources to pay for a trainer or a coach, there are certain ways that he must do in observe so that he will not get injured while doing plyometrics. The first thing that he can do is to condition himself and make sure to strengthen his legs. It would also help him if he does things gradually like starting with small jumps and making them explosive during the progress of the exercises. Wearing shoes with excellent cushion can also do a lot of help. If these things are followed, one can really benefit from these exercises without the injury.
