Finding a hidden camera before it starts transmitting is the ultimate counter surveillance move. Lens finders are able to find a hidden cameras lens whether the camera is working or not, whether it is powered on or off. When high powered IR sensors light up they reflect off the cameras lens. A slow sweep of the space will reveal the hidden camera lens as a bright red dot when looking through the lens finder's focal point.

Photography is about creating an image that you visualize when you approach a scene. What you include within your frame and exclude determines how you compose your image and therefore, the story you are creating.

This comes before you have a lens and a camera. Your eye, your personality, your style is the most influential aspect to how you will then capture your image through your tools. Knowing your camera and lens’ capabilities and restrictions then enables you to capture what you envision.

Basically, in order to zoom in at different focal lengths, your lens with have a certain amount of glass elements within it in order to achieve the variety your zoom lens allows. A higher number of lens elements inside will increase light diffraction and record a softer image due to the waves of light entering the lens being spread out as it passes from one element to the next.

Seeing something worth capturing, thinking about the image you want to create and why prior to capturing it, and then refining it with a strong and effective composition is what will make your image take on the quality of being great. When we just raise our camera and start shooting without a thought, this will most likely result in you looking back at it at a later stage and wonder ‘why on Earth did I take this? What was I thinking?’

This isn’t to say that I feel that prime lenses far out-weigh zoom lenses. Not at all. This is not a prime versus zoom post. I do find the set field of vision of a prime can inhibit me from capturing certain images from specific scenes that I would have loved to have captured. Zoom lenses enables you to look at a variety of interpretations of a single scene. Just remember – powerful images are created because you have found something worth shooting, not from the feeling that there are pictures to be taken.

But before you ditch your zoom lens and get ready to welcome a new member into your lens family, below is a list of pros and cons that will help you understand prime lenses more:

Shooting with a prime lens, also known as a fixed lens, is a completely different experience to shooting with a zoom lens. First off, a prime lens is a lens that has a one fixed focal length. What you see is what you are going to get.

The SpyFinder Pro is a lightweight battery powered device that allows you to quickly identify and locate a camera by using an array of ultra-bright LED's. When the camera is found it is highlighted to the user, where it appears as a flickering bright spot of light. The SpyFinder will find any hidden camera transmitting or not. It’s so small you can carry it in your purse, suitcase or briefcase to have it with you at all time.

I personally prefer using a prime lens when I am out photographing wildlife, but I will always ensure that I have a trusty zoom lens, generally a 70-200mm or wider, so that I can capture the bigger picture should I envision the shot I want.

The removal of a hidden camera threat is made easier with this durable, professional grade camera lens finder. The DD1200 is the highest grade camera lens finder available and was designed specifically to remove hidden camera that other detectors cannot find. The high powered adjustable LED's enable long and short range camera lens detection beyond what any other lens finder is capable.

As we know, a wide aperture allows more light to enter the lens. A by-product of this is that more light is seen through the viewfinder, allowing focusing to become a much easier task as it is easier to confirm focus.

The beauty of a prime lens is that you already know your set field of vision. You know you cannot zoom in further or pull back because you are either too close to your subject, or you wish to get in closer than what your lens allows. You know what field of vision you are working with from the beginning and with practice, you will start ‘seeing’ compositions relating to this fixed perspective when you approach sighting after sighting.

I shoot with a Canon 300mm f/2.8 for my wildlife photography. This lens forces me to pay attention to composition and how I am going to effectively tell my story through my image. I may be limited with what is within my frame, but I am not limited to what I can create. I am forced to be more creative due to this ‘limitation’ as I cannot play around with different focal lengths and then later scroll through images that I took and choose which one I prefer. That in itself already defeats the point of visualising what you want to capture, and then defining it through composition.
