So, you're thinking of getting a new lens, but you're not quite sure whether to get a prime lens or a zoom lens. Both types of lenses have their benefits and drawbacks, and you want to make sure you make the right decision and get the lens which best fits your photographic needs.

So you may be wondering what the point is of using a prime lens. Surely if you have the choice between a lens with flexibility and one with no flexibility, then surely the[..]

I was shocked. Was she cheating right in front of me, not even caring? I went up to the high school that day to pick my girlfriend up from school and wound up going home by myself while she rode home with another guy. That was the beginning of the end of that relationship and I hadn't seen it coming. I hadn't been paying attention, I'd been taking her affection for me for granted. And, it goes without saying, I had probably not been paying much attention either, to how I had been treating her. But, I had learned a lesson from that sweet girl. I needed to pay a lot of attention to how I treated other people and how they were treating me, instead of being satisfied with hearing words that[..]

Leica 35mm - This lens is very fast, offers top-class image quality in low light, but is large and heavy. - Fields of view - as focal lengths become longer, fields of view become narrower and narrower. Sigma 14mm - A wide-angle for the 35mm format, designed to provide a super wide-angle for digital cameras. Equivalent to 21mm on many slr digitals, such as the nikon d1 series. Canon 20mm - A very useful ultra wide-angle for 35mm and giving a 35efl of about 30mm on digital cameras. These single focal length, or prime, lenses generally give excellent, distortion-free results. Canon 28mm - Compact, fast (having a wide maximum aperture), and easy to use, a 28mm lens is one of the most[..]

The sensors found on digital SLR cameras are much bigger than their point-and-shoot camera counterparts. This allows them to have a larger area for capturing light and, potentially, much greater sensitivity with less lighting. A dSLR's extra sensitivity is particularly useful for # Taking pictures in dimly lit areas. # Freezing action by shortening exposure times. # Using smaller lens openings to increase the amount of subject matter that's in sharp focus. Just in the Canon digital camera line, you can find digital SLRs with 22.2 x 14.8mm to 24 x 36mm sensors (the size of a 35mm film frame). On the other hand, many of their digital point-and-shoot cameras use a sensor that measures only[..]

Many contact wearers consider contacts as regular merchandise, and not medical devices. Because of the health risks associated with improper care of contact lenses, it is imperative that consumers are educated about the importance of using them properly. One such error many people make is wearing contacts too long and the contacts eventually become over worn. Many contact lens wearers have experienced wearing over worn contacts. Studies conducted on the side effects from long-term wearing of contact lenses, such as by Zuguo Liu et al., 2000, concluded that "Long-term contact lens wear appears to decrease the entire corneal thickness and increase the corneal curvature and surface[..]

Copyright (c) 2009 Kentaro Konika The Nikon brand is famous across the world. Synonymous with quality and durability Nikon has carved out a large market for themselves, competing with the likes of Canon for the top-spot in the camera world. The Nikon company started out small but has grown into one of the most successful commercial camera manufacturers in the world. The company started from humble beginnings shortly after the end of World War II, launching the Nikon I in 1948. With this as their starting point Nikon continued to build on their success, quickly introducing a second camera to the market, the Nikon M, one year later in 1949. During the 1950s the brand continued to grow with[..]

Among all the lenses that are available the fisheye lens is low on most people's list of priorities. The uses of this lens are limited and it is rather expensive. Nevertheless, it can be highly effective in the right situation. It is sensible to hire a fisheye lens from a professional photographic dealer and try it out before deciding to buy one. If there seem to be many genuinely worthwhile uses for it, then and only then consider a purchase. Most people looking through an SLR camera with a fisheye lens for the first time find it highly amusing to see the world through a 180-degree angle of vision. Objects appear severely distorted, and it is easy to get carried away by gimmicky shots[..]

Digital cameras come in diverse shapes and sizes, from the smallest point-and-click models that just about anyone can put in their pockets to large pro cameras that weigh several pounds and need special carrying bags. The price range also varies significantly. At the low end of the spectrum cameras can be had for $50, and at the high-end, the professional cameras go for $6000 or more. Two of the biggest decisions you need to make when choosing a camera are: what is the type of camera you want, and how much you are prepared to pay. That will narrow the field considerably. Here are the main types of cameras you can choose from: Compact Cameras If you only want to take pictures of family,[..]

Thin eyeglasses bring attractive appearance and light ones bring comfort. Thinner and lighter high-index lenses are the perfect choice for wearers who pursue these features. A common sense is that lenses for myopia correction are thicker at the edge and thinner at the center. Stronger prescriptions require thicker lens edges. With the prevalence of rimless and semi-rimless eyeglass frame styles, those conventional plastic or glass lenses’ thick edges are even more obvious, which can detract from the eyeglass appearance. The prescription of a lens is determined by the amount of light refraction that your myopic eye need. A higher prescription requires the lens to bend more light to[..]

A new competitor has been added to the variety of lenses used in cataract surgery today. The Food and Drug Administration (FDA) approved Pfizer’ Tecnis® Multifocal Foldable Acrylic Intraocular Lens (IOL) in January 2009, adding it to the list of successful multifocal lenses such as ReSTOR®, that have brought clear vision to millions of cataract patients. Like its predecessors, the diffractive lens design that Tecnis® uses directs light differently in different zones of the lens. Each zone is designed to address either distance, intermediate or near vision. The Tecnis® lens not only replaces the natural crystalline lens to eliminate cataracts, but it also corrects presbyopia, a[..]

Digital cameras are the "in thing" now. Almost everyone owns one and knows how to use it. Imagine you are out on a vacation and want to take some snaps of family and friends. You take the camera out of the bag only to discover that the memory is full. If it was a case of film cameras, all one needs to do is get a new roll of film and replace the old one with it. But with its digitized version, you will either have to delete some old photographs or transfer it to the computer and free memory space. Or you can get additional memory storage media and insert it into the gizmo. This is one mandatory digital camera accessory. The next essential accessory is the battery. Always remember to have[..]

The concept of lenses made from silicone hydrogel was first proposed over 20 years ago. The potential benefits were clear but the technological challenge was as difficult as needing to combine oil and water to produce an optically clear product. Researcher organizations have to date invested considerable academic and financial resources to achieve the high performance soft lenses of today. They have done this quite simply because they see this material as the way forward and the ultimate standard of the future. At the time of writing, silicone hydrogel lenses are available in the USA from four manufacturers: "Night & Day" and "O2OPTIX" from CIBA Vision, "Pure Vision" from Bausch[..]
