Review of Nikon Digital Camera Lens

!±8± Review of Nikon Digital Camera Lens

A huge number of professional photographers use the Nikon DSLR cameras to take the best shots of their career; this is because of the fact that Nikon is one of the best providers of high quality cameras and lenses. Good photography is never possible without good lenses. Nikon provides a variety of lenses for a wide range of purposes, and picking the right one can be a tough call for an amateur. Nikon has its very own terminology when it comes to lenses.

Suppose the lens name is "Nikon AF 28mm f/2.8D", this is a simple lens and does not possess zoom capabilities, it is commonly known as the Prime Lens. The name can be divided into different segments, the first one is 28mm this is the focal length of the lens. If this lens had, a zoom function then the name would have been more like 70-200mm, which would suggest the wide-angle (70mm) and the telephoto settings (200mm) focal lengths of the lens.

The next part of the name, f/2.8 is the maximum aperture sizes of the lens, the smaller the f-number the higher the speed of the lens. A high-speed lens is good for low light photography as it allows more light to be directed to the sensor. The last part of the name suggests the feature provided with the lens, in this case it is D, which means that the distance between the lens and the object is sent back to the DSLR, thereby adjusting the exposure to create a better picture.

Some other terminologies are discussed below;
o G-lens: These lenses come with an aperture control ring on the lens itself.
o VR-lens: this stands for Vibration Reduction; this helps the photographer take stable and clear photographs at extremely low shutter speeds.
o AF-S: ideal for the wildlife photographers, who want to take good pictures of their subjects without disturbing them. The Silent Wave Motor uses hi-tech capabilities to zoom in automatically without causing any noise.
o IF: this stands for Internal Focusing, these lenses are very affordable and the shape of the lens does not change when you try to focus as all the focusing action takes place inside the lens.
o ED: stands for Extra-Low Dispersion, a lens without this feature will have chromatic aberrations in the photo.

There is no single lens that packs all the features, so you need to mix and match according to your requirements.
o If you want to take sports photographs then you can go for the Telephoto lens with AF-S capabilities.
o For portraits and scenery capture, you should go for the wide angled lenses with VR and ED.
o For taking pictures of the landscapes, you should opt for lenses with internal focusing (IF) as the wide angled IF lenses give good view of the field.
o If you like to capture small objects like flowers, butterflies, Bees then you should go for the Macro lenses with optical zoom capabilities.
o For traveling purposes, you can choose the Mega zoom lenses that offer great zooming capabilities, both optical and digital.

To summarize, we can say that there is a lens for every single purpose so you should pick your lens carefully while composing a shot.

Digital Photography Help - Buying Tips

It is always a tough decision when you set out to purchase your first digital SLR. Should you go with Nikon, Canon or another brand? Should you spend a lot of money on a body and go with the kit lens? What lenses should I buy, mega zoom or fixed focal length? These are all questions I try to answer on this recent Skype Call with a reader. He is trying to decide should he spend money on the D3100 or the D3000. If he spends the money on the D3100 he will not leave himself with any room to purchase good glass and will be stuck with the kit lens. If he goes with the D300 he will have enough money to pick up a nice starter lens and save a few hundred dollars towards his next purchase. I feel that a lot of photography when you are starting out is learning the theory and methods behind capturing great images. The equipment will play a roll as you grow but just starting out you want to get a basic knowledge of composition, exposure and editing and grow from there. Once you have the basics down than you can decide which direction to go next and when to upgrade. Just remember glass glass glass before spending money on a body and being left with no good glass.
