•The wide-angle lens is a focal length shorter than the standard lens,a perspective greater than the standard lens,a distance longer than the fisheye lens,perspective smaller than the fisheye lens photography lens. The wide-angle lens is divided into the ordinary wide-angle lens and the super wide-angle lens two. 135 camera focal length of an ordinary wide-angle lens is generally 38-24mm,with a perspective of 60-84 degrees; the super wide-angle lens focal length of 20-13mm,with a perspective of 94-118degrees. Due to the short focal length of the wide-angle lens,the perspective is large,in a shorter range of shooting distance,and can capture a larger area of the scene •Wide-angle additional lens principle and features: The front wide-angle lens is actually an inverted telescope system. It will come from far away parallel light "expansion beam" and then into the original lens imaging. It is equivalent to the main surface back,the focal length is shortened. According to the same reasoning,plus the front wide-angle lens after the value of the aperture F number is unchanged •The effect of using a wide-angle additional lens has the following characteristics: •Can increase the spatial depth of the photographic image •Longer depth of field to ensure that the front and rear of the subject can be clear on the screen •The lens covers a large area,shooting a wide range of scenery •The same shooting distance outside the scene as the standard lens shot in the image of the scene is small •The picture is prone to perspective distortion and image distortion defects,the shorter the focal length of the lens,the closer the shooting distance,the more significant such defects •The effect of wide-angle lens: •Can increase the spatial depth of the photographic image •Longer depth of field,to ensure that the subject of the front and back of the scene can be clearly reproduced on the screen •The lens covers a large area,shooting a wide range of scenery •The same shooting distance at the scene shot as the standard lens shot in the image of the scene in the picture is small •The picture is prone to perspective distortion and image distortion defects,the shorter the focal length of the lens,the closer the shooting distance,the more significant such defects •Small size and lightweight,easy to load and unload,and easy to carry •Increasing the coverage of the field of view when photographing,will not be able to take the scene more complete •The mirror surface adopts a high transmittance multi-layer coating lens,enhances the image contrast,and reduces the halo to reduce dispersion,the best image •Applicable to: All cameras and camcorders with 58 mm size lens filter thread (vignetting may occur in digital SLR lenses) Note for use: •Wide-angle lens to shoot the scene near the large,small,exaggerated perspective effect. The closer the subject is to the lens exaggeration more obvious. So when shooting portraits of people can not be too close to the camera,otherwise it is easy to take a 'fat nose and ears' deformation photos •Wide angle lens using a hood or color filter,it is easy to block the lens perspective around,so that the image field is dark,and this situation,in framing,is not easy to notice,but in the photo is very obvious. Therefore,when using accessories,be sure to understand their scope of use from the manual •Electronic flash covers an angle of view generally comparable to that of a 35mm lens on a 135 camera. Therefore,use a less than 35mm wide angle lens for flash photography,to add diffusion cover in front of the flash window,if not,you can wrap a layer of white paper or a white handkerchief to increase the flash area •The part of the lens marked with Macro text can be separately screwed open and need to be used together with the lens to produce when shooting macro Package included: •1 x 52mm 0.45X Camera Wide Angle and Macro Lens •1 x Front Lens Cover •1 x Rear Lens Cover •1 x Lens Storage Bag •Other items not included
