A fisheye lens gives a 180° field of view.
A telephoto lens gives an 800mm field of view.
Before buying a lens, find out what you want to be shooting and what your budget is.
Wide angle lenses should be used when prominent foreground objects are present.
When using wide angle lenses, get close, have interest in the foreground, but do not try and include too much in the scene.
Having a wide angled lens also comes in handy when shooting tight areas like small rooms, cars, caves, etc. Because they can give volume to the small area.
Standard lenses tend to range from about 35mm up to around 85mm.
Standard lenses are great general or basic lenses.
A standard lens can be used for wide angles and for zoom-ins.
When taking telephoto photos, you have to zoom in a lot and get close if you really want a good photo.
Telephoto zooms come in handy when taking portraits.
When using a telephoto zoom, don’t get lazy and let your lens do all the work, physically get closer to the object that you’re photographing as much as possible, and shoot away.
A “fast” lens is usually one that has an aperture of f/4, f/2.8 or larger.
If sports is one of your primary subjects, a telephoto zoom such as a 70-200 f/2.8 is an excellent choice.
If you want to look like the pros you’ll want a 300mm f/4, or 300mm f/2.8 or 400mm f/2.8.
Don’t forget to make your shutter speed fast enough!
1/500 to 1/1000 shutter speed is the minimum.
If you’re using a longer lens to try and capture movement, try and shoot in a direction in which the object is coming at you instead of shooting parallel movement.
If you want to shoot smaller objects, try using a macro lens.
If you want to shoot architecture, tilt-shift or perspective correction lens should be your choice.
There is a zone where a camera can only focus its lens at a single point, but there will be an area that stretches in front of and behind this focus point that still appears sharp. This zone is called the depth of field. The depth of field is not a fixed distance because it can change in size. It described as either shallow when only a narrow zone appears sharp. It can also be described as deep when more of the picture appears sharp.
To be able to control the depth of field you need to know how to control your aperture first. You need to know how much depth you want in your picture. If you’re taking a portrait. it’s better to have a shallow depth of field so that the focus is on the person’s face. Having a shallow depth is also good when you need to separate a subject from a busy background, street shooting, event shooting, and many other things! On the other hand, when taking landscape photos, you want to make sure you have a deep depth of field so that everything in the frame is in focus.
- A photographer should be able to tell if their exposure is correct and be able to make the necessary adjustments by reading the histogram.
- RAW format will give you access to the full capabilities of your camera.
- Your camera has the option of selecting the auto focus points for you.
- Learn all AF modes. The one-shot mode will stop refocusing once it’s locked onto the subject. AI- Servo AF mode won’t lock the focus and it will constantly refocus, and it is a great focusing mode for sports and other fast-moving subjects. AI focus will automatically from one -shot to Servo if it detects movement in the frame.
- In aperture priority mode, your camera will vary the exposure settings depending on the aperture value you set. This is a great setting for shooting portraits with blurred backgrounds.
- The shutter priority mode gives you complete control over shutter speed while making all the other settings automatically, according to the selected value.
- Learn what the lowest speed is for you and stick to it for motion free images.
- Learn to set white balance manually, according to each lighting situation.
- Master metering modes by reading the manual.
- Learn how to pick the correct ISO value depending on the lighting.
- Auto ISO can help you when shooting hand held.
- Exposure compensation is a +/- scale that will tell your camera to increase or decrease exposure.
- Manual exposure is the last stage in learning how to use your camera settings.
