What is the best camera specification for taking soccer photos?

November 20th, 2012 4 comments

I want to get a decent camera for sports photography so I need to zoom in and get a decent not blurred shot. What sort of gear do I need?

There’s gear and then there’s features. So, what I’ve done is list the gear, and under each item, I’ve listed the features to look for, as well as an example.

1) A single lens reflex camera (either digital or film):
–for digital SLR, it should have low noise at high ISO settings (i.e., in low light the camera can be set to have low-noise images)
–for film SLR, use high ISO film
–make sure the SLR has the ability to control the aperture and shutter speed; some older film SLRs do not offer manual controls at all.
–ideally, a quick response time, so when you push the release, it takes the photo.
–a fast frame rate (fps or frames per second) of 5 fps or faster.
EXAMPLE: Nikon D2H, Nikon D300, Nikon D3, Canon 1D mark II.

2) A telephoto lens with a wide aperture (such as f/2.8).
–ideally, should have a built-in focusing motor for speed (such as Nikon’s AF-S motor)
–ideally, with image stabilization
–at a minimum 200mm up to 600mm
–zooms can offer some versatility
–lens should have tripod mount or tripod foot on it.
Examples: fixed focal length lens 400mm f/2.8; zoom lens 200-400mm f/4

3) A strong monopod

What you would do: set the camera to the highest ISO you can tolerate for noise or set it to auto ISO. This allows the camera to expose with the fastest shutter speeds to stop action. Typically, you’d have the camera in manual exposure mode, selecting a fast shutter speed like 1/500 or 1/1000 to freeze action, and a wide aperture to let in light and blur distracting backgrounds. The lens should have a foot on it to support its weight, mounted on a monopod. Do not attach the monopod to the camera, because the weight is all in the lens and this will stress or warp your mount.

Best value, digitally: a used Nikon D2H. This is a pro-level camera that sells for about $400 used, without lens. It’s 4.1 megapixels, which is enough to make 8 x 10 images with no problem. A lens will cost you a lot more, actually. A decent enough lens on a budget is still expensive. At the least expensive end, you’d be looking at a 70-300mm AF-S VR lens ($459) and that’s only if you’d be shooting in decent light.

For film, a used film SLR (like a Nikon N80, about $100) loaded with ISO 800 or 1600 film would be a very inexpensive choice, but you’d still have to buy a good long telephoto lens.

If all this is out of your price range, then look for a SLR-like point and shoot with as big an optical zoom as you can afford (you may see this as 12, 15x, or even 18x). Set the ISO high, at least 400 and higher if you can stand the additional image noise. Use a monopod or tripod (if they’ll allow you to have a tripod). Because the camera is slow in responding compared to an SLR, you’ll have to anticipate the action.

Hope this explains things to you clearly and in an easy way.

How Fast Should My Lens Be?

May 17th, 2012 7 comments

If you are still using a point and shoot film or digital camera, your choice of lens speed is limited to the camera. However for those of you who decided that it is time to move on and upgrade to an interchangeable lens camera, whether it happens to be film, or digital, you are no doubt have been looking at the many lens options available. Large majority of people switch from a point and shoot to a Single Lens Reflex camera. While overwhelming percentage of people move to a Digital SLR, Film SLRs are still popular, and function essentially the same. So, for the purpose of this article, the two types will be treated as one. Lenses are available in so many different combinations, and varieties, that discussing them all is far beyond the scope of this article. However, they all have one thing in common. They are all broken down into two groups: slow, and fast. If you are still struggling with choosing your first lens, or just trying to make the right decision, while faced with many choices, this article should help.

First of all, the speed of the lens is determined by the size of the opening, known as the aperture. The larger the opening the faster the lens is considered to be. Typically, lenses marked with F4, F3.5, F2.8, and smaller are considered fast, while lenses marked with a bigger number are slower. I know this may sound odd, but the smaller the number the faster the lens. If you are new to shooting with an SLR camera, you are most likely looking at “zoom” lenses. Most zooms today have a variable aperture. This simply means that at the shortest end, the lens is faster than at the long end. For example, a typical lens a 28-80mm. This lens zooms from 28mm to 80mm, and it is a very good starter lens. This type of a lens will typically have a F3.5 aperture at 28mm (short end), while at 80mm (long end) it will be F4.5, or F5.6, which is considerably slower than the short end. Typically, the faster the lens, the more it will cost, and the heavier it will be. Most casual shooters look for very versatile lenses, and faster lenses certainly offer more flexibility in certain situations.

Now that we briefly discussed the concept of speed, lets figure out whether you really need a fast lens. The first thing that you have to think about is your shooting habits. Everyone is different, and very much unique. Some shoot landscapes, some only people, others night scenes, some shoot under water, and so forth. Typical casual shooter will likely shoot during daytime, and will likely be shooting portraits, landscapes, city scenes (during a vacation perhaps), and other fairly undemanding environments. If you shoot a lot of photos in dim light, like night clubs, restaurants, museums, outdoors after dark, and other dim light situations, a faster lens is definitely a boon. However, you should always keep in mind that most zoom lenses, while faster at the short end, will be slower at the long end. This is very important, because if are going to be shooting at the longer end of the lens, when shopping for a lens, keep this in mind, and you will save yourself some money. Let me explain. Take two lenses, one is a 28-80mm f2.8(short end) / f5.6(long end), and another lens, 28-80mm f3.5 / f 5.6. These two have an identical range, however the first is faster at the short end. This larger aperture does not come free. You may end up paying 2 times as much as the second lens. If you are going to be mostly zooming to the long end of the range, compare and price your lens at that end.

If you are going to be shooting mostly portraits and other static scenery and plan to use flash, or a tripod most of the time, you will not need a very fast lens, because the added speed will likely be of little benefit to you. As such, you will do just fine with a F4.0 or slower. Action shooters often benefit from faster lenses, and if you are planning to capture sports, animals, and other moving subjects, a faster lens may help at times. The single biggest benefit of a faster lens is the freedom it gives you, when the light is limited. If you are an action shooter, and capture a lot of action in dim light, the extra speed will be very helpful, and allow you more hand-held shooting. Always evaluate how much you are going to be shooting in different environments. Action and low light shooters will most benefit from lenses with apertures of F4.0, and larger. If you think low light, and action will be very infrequent, and you are comparing two similar lenses, choose the budget one, which will likely be just a bit slower. Often, a price of a zoom lens with just a slightly smaller aperture at the long end will be hundreds or dollars less than a similarly sized zoom with a slightly larger aperture.

Most modern Digital SLRs can really offset the need for a fast lens through higher ISO settings, something that Film cameras do by using a faster film. With Film cameras, you would need to switch a roll of film to change the ISO speed. If you use a Digital SLR, switching an ISO is easy, and could be done at any time. This is a huge benefit, and reduces a need for the faster lenses. Unless you are planning to make money with your camera gear, fastest lenses will not be cost effective.

Consider borrowing, or renting a fast lens, in the range which will meet your shooting needs, and test it in the different environments in which you will be shooting. If you are not pushing the limits of the lens, chances are, you will be OK with a slower, more budget friendly alternative. Make sure that you know your budget, and how actively you will be involved in photography. If you plan to trade-up your equipment in a few years, keep in mind that technology only gets better, and making a big investment will make more sense if you are going to get a lot of use out of it.
