Getting Started with Camera Lenses for a Digital SLR
You may be totally confused about where to start, when it comes to buying a digital slr camera lens for your digital SLR. Should you just go for the largest lens you can find? What does all of that intense terminology mean? How are you supposed to make a sound selection and find a great value at the same time? If you have some basic knowledge to help get you started, it does not have to be a daunting process.
Concerning Focal Length
The first thing you will have to keep in mind is what is alternatively known as either focal-length multiplier or focal-length magnification. This is the conversion that results from the APS-size sensor used on a digital SLR. Put simply, your digital SLR lens is going to act in a way bigger than it actually is.
A 50 mm lens really gives you an angle of view compatible to a traditional 75 mm lens, because the conversion is about 1.5 to 1.6. 200 mm would be 300 mm and so on. But, this doesn’t actually change the optics principles or distortion of a particular lens sense or style. It only accounts for the angle of view.
Pay Attention to Apochromatic Correction
Aprochromatic correction, image stabilization and digital only lenses are a few other features or options to keep in mind. Starting with the latter, digital only lenses provide great value but won’t be compatible with a traditional camera, or potentially future SLRs with 35 mm lenses. Examples of this include the Nikon DX.
Apochromatic correction helps to improve image sharpness, and image stabilization will help you get better shots by counteracting camera shake or blur from slow shutter speeds. Also note that some camera bodies, such as those from Olympus and Sony, are designed to provide stabilization effects, and other cameras rely on the lens to provide image stabilization.
Top Brands to Look For
You will definitely have a wide range to choose from, when it comes to brands. The most recognizable of the bunch undoubtedly are Canon camera lenses, which have a great reputation as being high quality lenses in keeping with Canon camera bodies, as well. What’s more, you will find some great options from Olympus, Tamron, Panasonic, Nikon and a variety of other manufacturers too.
More customized solutions for a particular setting or style of photography may be found with some of these brands. You also may only be interested in buying the same brand for the camera body and the lens. While this isn’t a necessity in most cases, this often offers greater synergy and performance for your shots. It’s entirely up to you whether or not you’d like to do this.
This has been just a simple starting guide for digital SLR cameras and camera lenses. You will have to cross the bridge of how much cash you need to end up spending as well, and there are surely other things to consider. You will always be able to find a great match for your specific needs and your budgetary constraints, whatever they may be, but it’s always better to purchase one versatile, top quality lens than needing to purchase a variety of more limited and lesser quality lenses.
