Digital SLR Review

Do you ever feel undecided in choosing a target for your digital SLR? I know it is very annoying, because of the cost of lenses is one of consideration.So before choosing a goal, ask yourself what you need, what is the object that you want to capture with the lens? Therefore, it is under three main factors that must be considered before buying your goal based on your DSLR or camera.1.Focal Length2.Prime Zoom3.Maximum ApertureFocal LengthDistance object is to determine the impact the focal length .

Nearest object using shorter focal length, and then object using longer focal length. So how to decide the number of focal length? Here are some example.below 35 mm to 70mm Landscape and Interiors35mm: Portraits70mm 300 mm: Portraits and Sports300mm and higher: Wildlife and SportsPrime ZoomPrime or lens is the lens that can zoom, but zoom lens can do. Zoom is actually the control of focal length. Probably people ask, why must still select the first target if I had best choice you can enlarge as I like?

Some comparison.Cost simple: to the same specifications, the primary objective is cheaper zoom lens.Quality: Most people agree that the photograph taken by overriding goal is better zoom lens.Weight: First objective is lighter, zoom lens is heavier.Speed: In the opening period, the primary objective is faster zoom lens.Flexibility: If you want to capture photos throughout the focal length as the landscape, interiors, portrait, sports. You only need a zoom lens to zoom in and out. If you prefer primary objective, you may need three.

Price: Do you think the total cost for the first three lenses will be cheaper than a zoom lens? Portability: Do you think that bringing the first three lenses will be easier than a zoom lens? Summary ApertureNow that is why we must decide the maximum opening for a goal? Since the lenses have the widest aperture are usually very expensive. Enlarged opening allows more light, more narrow opening to allow less light in when taking a picture of the interior, light conditions indoors is not as good as outside, so you need greater openness to more light, if not, the image you will be taken dark.

Another right eye is to satisfy the shutter speed. We need higher shutter speeds for shooting fast objects. When the shutter speed is set very short-term, eg 1 / 2000 second (just 0.005 seconds) and you do not set your opening wider, then the picture you took will underexposure, look dark. Last, the depth is about the field, the background blur is caused by the impact. Opening the larger decrease depth of field, blurred background, narrow opening is to increase the depth of field, background clearly.
