Digital and Optical Camera Zoom: What’s the Difference?

The Best Summary about Digital Camera Optical Zoom by Alex Don

If you are new to photography, figuring out what zoom power you need and differentiating between the different types of zoom can be quite overwhelming. A number of new terms referring to zooming have been introduced lately in the marketing language of camera manufacturers, which only increases confusion. Most mid-priced digital cameras have an incorporated 3x/4x lens. These numbers refer to optical and digital zoom. Most cameras have both optical and digital zoom, with the exception of a few low-priced ones, which tend to make dull and fuzzy photos. A digital camera’s zoom function is quite similar to the one of a film camera and does the same thing, namely bringing the subject closer. Anyway, in digital cameras here are two types of zoom, an optical and a digital one. Optical zoom is the one similar to the zoom of a traditional camera. Digital zoom, on the other hand, simulates zooming by blowing up a selected part of the picture. It shouldn’t be mistaken with photo editing, which refers to applications used to modify the image after it’s been produced. Another common misconception about this type of zoom is that it is particularly useful for long distance photos. Optical zoom is much more important in a digital camera and it should be the one used as a criterion when comparing different models instead of digital or total zoom.

The quality of a digital camera is more dependent on optical zoom. To create even more confusion, manufacturers have begun to use the term of ‘total zoom’. At most it can refer to the fact that a camera has both types of zoom functions, digital and optical. Traditional cameras like 35 mm or APS only had optical zoom. Optical zoom uses an incorporated lens to bring the image closer to the photographer. Professionals associate digital zoom with digital video cameras. They don’t think of it as a real zoom for digital cameras because it just enlarges a part of the picture. In other words, it crops part of the image and enlarges the rest, resulting in a loss of quality. It works in the same way as the cropping and resizing options of photo editing applications. Another new term in digital photography is that of ‘smart zoom’. This type of zoom avoids interpolation and thus maintains the quality of the image.

People sometimes compare optical zoom to resolution when they purchase a digital camera. The power of digital zoom and the resolution are two different things with no connection to one another. The resolution expresses the number of pixels in the picture, while optical zoom refers to the power of the lens. Many photographers don’t trust this feature and would rather crop and resize the photo themselves on the computer.

Digital Zoom vs. Optical Zoom

The Summary about Optical Zoom Digital Camera by JR. Lang

The zoom lens of digital cameras and camcorders is the ability to vary focal length and, thus the angle of view. Both digital cameras and camcorders have zoom capability. For the consumer this can be confusing because there are two different types, known as Digital Zoom and Optical Zoom. When in doubt always go for optical zoom when shopping for cameras and camcorders.

Digital Zoom vs. Optical Zoom

The digital zoom enlarges images by magnifying the actual pixels. The finished image is thus affected and lacks clear definition. Simply put, digital zoom merely captures pixels and magnifies those and produces inferior photos, always go with optical zoom, which is a much better quality zoom capability.

Optical zoom, unlike digital zoom, actually utilizes the movement of the lens. The focal length is changed and the image that passes through the lens is captured with optical zoom. Higher optical zoom ratings give better image quality. Simply put, optical zoom magnifies the size of an image by adjusting the lens. Unlike digital zoom, optical zoom enlarges the subject without sacrificing resolution.

Optical zoom ratings vary from 3PX to 20PX and the higher ratings give the best image quality. Optical zoom gives you all the benefits of the camera’s and camcorder’s maximum resolution, combined with the camera’s ability to focus in tight on faraway action.

Often times an optical zoom is more important than resolution because it means you won’t have to magnify your subject and then use software to crop the image and discard some of the resolution as a result. Optical zoom works much like the zoom lens on a 35 mm film camera. It changes the length of your camera lens and draws the subject closer to you.

Digital zoom has its place. Photos online can be a much lower quality in the camera and still appear acceptable when sent through e-mail or posted on a web gallery. But, if your goal is to print any of your photos you need a camera that has a high optical zoom rating and if your camcorder or camera also has a digital zoom function you should turn it off when taking those pictures. Some vendors tout a high total zoom that includes digital zoom, and it is not the true Optical Zoom rating. Always look for the true optical zoom rating.

Types and Models of Polaroid Digital Cameras

The Executive Summary about Polaroid Digital Camera by Russ Snapper

The type of camera with self-developing film is known as instant camera. Polaroid Corporation makes the famous Polaroid cameras.

Based on the type of film used, Polaroid cameras can be classified. The older Polaroids used instant film roll. Roll films were of two types: Positive or developing agent and negative. Pack film was later used in cameras, in which the photographer has to pull the film from the camera for developing and subsequently the positive and the negative have to be peeled separately while developing. This Pack film was available initially in a rectangular format and later in square format. Subsequent Polaroids such as the once famous SX-70 model utilized a square format integral film, which had the developer, negative, fixer etc in the same film. Polaroid digital cameras are now available in various types. The m635P model from Polaroid Corporation was designed solely for promotion of breast cancer research. Polaroid Corporation along with actress Elizabeth Hurley initiated to offer a combined donation of $60,000 for the above Research foundation in the year 2006. Pink, light pink and magenta models of Polaroid digital cameras were launched especially for the above good cause and awareness.

One more noted achievement from Polaroid is the launch of the ION digital camera which combines high-end features and is easy to use.

Polaroid Digital Camera Problems You Should Know About Before You Buy

The Executive Summary about Polaroid Digital Camera by Chris Campbell

Polaroid digital camera problems have overwhelmed consumers and the manufacturer. The Polaroid a520M was a camera that Polaroid probably wishes they never released to the public. This camera had underexposed images when you were not using the flash. The list goes on with this particular camera. There were a few positive things about the camera, but not enough for Polaroid to keep the camera on the shelf.

Then came the Polaroid digital camera problems with the x530. A Hong Kong company under the Polaroid name produced the camera and the image quality was deplorable. Consumers were quick to judge this particular camera. Digital cameras are not easy to make, but if you do not use the technology available, you will have problems and dissatisfied customers. This camera was also recalled and pulled from the store shelf. Anyone that had this camera was issued a refund. Next, Polaroid produced the awkward looking PDC-3000. This camera was not only awkward looking it delivered poor picture quality.

When looking for today’s digital cameras, one has to practice scanning and comparing reviews and specifications on all digital cameras. Even companies with a unique reputation in photography can produce a camera that will not make it the world of photography. Polaroid digital camera problems are long and drawn out. The digital cameras mentioned have since been taken off the shelves, but you still need to read any reviews of other cameras to see if it is what you need. Always compare digital cameras with a checklist to see what camera will be the best for your needs.

Canon Digital Video Camera

Canon Introduces First Hybrid Digital Video Camcorder with 35mm SLR Camera Design and Performance Features

Canon Digital Video Camera

New OPTURA Breaks Boundaries between Digital Motion and Still Imaging – Captures High Speed Subjects Undetectable to the Human Eye -

Canon U.S.A., Inc., the leader in optical imaging technology, today introduced the OPTURA, the world’s first hybrid digital video (DV) camcorder with design and performance features previously limited to 35mm SLR cameras. The Optura harnesses the power, connectivity and superior resolution of the mini digital video format while integrating Canon’s design and technology expertise in the video and 35mm SLR camera product categories.

In addition to recording full motion video and audio digitally, the Optura captures still images undetectable to the human eye. Using an exclusive Progressive Scan Movie mode which acts as a digital motor drive, the Optura records high resolution still images of fast moving subjects at a rate of 30 frames per second (fps) – three times faster than the motor drive of a professional 35mm camera.

“The Optura marks Canon’s first entry into the DV camcorder market on a worldwide basis,” said Mr. Yukiaki Hashimoto, director and general manager, Canon Video Division. “We have integrated Canon’s many years of expertise as both a video camcorder and 35mm SLR camera manufacturer to develop a new and powerful digital imaging hybrid with extraordinary image capture and output potential. This product will offer unmatched versatility to meet a wide variety of still, motion and multimedia image capture needs of both business professionals and consumers.”

Optura’s Progressive Scan CCD Image Sensor & RGB Color Filter Rival Image Quality of Professional 3-CCD DV Camcorders

The Optura is the world’s first digital video camcorder to incorporate a Progressive Scan CCD image sensor which delivers high quality, full motion video and sharp still frame digital photographs. The Progressive Scan CCD reads each of its 360,000 effective pixels in a single scan to capture a full frame image every 1/60 of a second. This process achieves superior resolution and enables users to capture vivid, high quality still images of high speed action for TV display, computer input or digital photo prints. In contrast, other DV and analog camcorders use an Interlace Scan CCD which processes field images or half the scan lines every 1/60 of a second. This results in diminished still image quality since the CCD is only creating half a frame of information at a time.

Canon’s proprietary integrated circuits work in conjunction with the Progressive Scan CCD to process and selectively combine scan lines from the frames according to the recording mode: Progressive Scan Movie mode, Photo mode or Normal Movie mode.

The Progressive Scan CCD is complemented by a RGB primary color filter, rather than a complementary color filter found in other camcorders. The combination of this primary color filter with a Progressive Scan CCD achieves color resolution comparable to that of 3-CCD systems. The RGB primary color filter improves the reproduction of subtle intermediate gradations, making colors in still images more uniform.

Optura’s Versatile Recording Modes and Uses Define New Digital Imaging Hybrid

The Canon Optura distinguishes itself from all other digital video and still imaging products through its unique image processing and recording options. The Optura’s unique recording modes and IEEE 1394 digital connector are designed to suit a multitude of sophisticated imaging and computer application needs including, digital motion video, still image and multimedia capture? All in one unit.

– Progressive Scan Movie mode: This exclusive Canon feature acts as a digital motor drive recording images three times faster than the motor drive of a professional 35mm camera. Users will capture the most intriguing, high resolution still images occurring within action – and previously undetectable to the human eye — by employing a Progressive Scan CCD and two new proprietary integrated circuits.

The Progressive Scan Movie mode allows users to record high speed action for the purpose of extracting high resolution, full frame images. These images may be displayed on TV, computer or output to a printer.

In contrast, the Interlace Scan system, common to other DV and analog camcorders, creates a frame image by using two opposing fields. This process creates a time lapse, causing image flicker during playback which makes printing high quality stills impractical. — Photo mode: This recording mode further distinguishes the product as a hybrid DV camcorder by transforming the Optura into a virtual digital SLR camera. In Photo mode consumers may record in full auto mode, so the camera will set exposure and shutter speed automatically. Users also have to ability control shutter speed manually by selecting “shutter priority” on the programmed AE dial. Similarly, aperture may also be manually adjusted by selecting “aperture priority” on the same dial.
