Although digital cameras have now almost replaced the traditional focus free cameras
which used to be hulking in the size and powered with the photographic focus free lens, but still you can notice the matured photographers carrying out their old cameras and enjoy clicking photographs; still there are camera assemblers promoting their focus free cameras in comparatively much more affordable price range & compact size.
The focus free cameras carry the aperture that you probably must have seen in the old cameras, it is fitted right next to the object lens covering it in round shape which adjusts the clarity (Depth of the field) by regulating the extensive light rays coming in between the focus, a snapper just needs to adjust the roller accordingly to get the top clarity figure.
There are certain positive & negative factors of focus free cameras, talking about the positives; you dont need to adjust the focal point every time you are clicking an image that gives you a real time shooting experience, and its pre installed aperture automatically decides the finest probable image clarity to be captured and above all, costs & photography expenses of these cameras go actually lesser than the trendy digital cameras, but it has got various negative issues too like if we talk of sharpness of the image than obviously it produces less sharper image while at the same time digital cameras allow you to set the focal point up to any extent for a scene, and you dont have to worry about the number of images that you can click; you can click unlimited number of images and even can shoot long videos too that
you can direct load to computer or print them out directly via the supported memory card.
