Kit lens is a lens that is sold in conjunction with a camera body. When the package is sold, the total price of the two (body + kit lens cameras) would be cheaper than when purchased separately. Though the kit lens has a lot of restrictions (such as image quality and the quality of the lens material itself), for those of you who have a limited budget, the combination of camera body + lens kit is a very attractive option because it is more efficient.
Before going any further, if you are fairly unfamiliar with the terms used in Nikon lenses. Here are some options for Nikon DSLR kit lens (which has certainly protest Canon, Nikon why?

1. AF-S DX NIKKOR 18-105mm f/3.5-5.6G ED VR

This lens is a kind of super-zoom lens focal length judging from the range on offer. Introduced in 2008 and sold bundled with the camera body Nikon D90, Nikon D7000 and Nikon D5100 and Nikon D3200, but can also be purchased separately.
These lenses are already using vibration reduction to reduce shake. To reduce the chromatic aberration (what’s that?), He has been using the technology of ED (extra low dispersion). Autofocus is also relatively quite fast thanks to the use of silent wave motor (SWM). This lens is a lens with a DX format, so it is only compatible with a crop camera (when used on a full frame camera, the resulting image will arise vignetting).

If for Nikon lens options we are relatively few, Canon provides a variation kit lens quite a lot. Here are some of his kit lens options:
1. Canon EF-S 18-55mm f/3.5-5.6 IS II
This popular kit lenses are usually sold with the camera body EOS 600D, 650D and 60D and has experienced three changes. When the purchased package, this lens is priced very cheap.
These lenses are cheap and although the picture quality is limited and the quality of ordinary material, but has a decent feature. Equipped with an image stabilizer which saves 4 stop exposure and has mfd quite short, about 25cm.
DPReview lens called this version much better than the previous generation and features of its IS function very well, so overall function as a basic kit lens is very satisfied.

2. Canon EF-S 18-135mm f/3.5-5.6 IS
Super-zoom lens is usually offered a package with the camera body EOS 600D, 60D and 7D. This lens had upgraded to the latest version with the STM (stepping motor). Canon claimed STM can improve the capacity and speed of autofocus and more silent.
Photozone claims that this lens is much better than the kit lens 18-200mm f/3.5-5.6 IS, has autofocus is quite good but you should use a wide aperture avoided because the results are quite soft.
Example photos:

3. Canon EF-S 17-85mm f/4-5.6 IS USM
These lenses are used typically sold bundled with a Canon EOS 60D camera body. In quality, this lens is better than the 18-55mm kit lens,

Example photos:

4. Canon EF-S 15-85mm f/3.5-5.6 IS USM
The kit lens is usually sold bundled with the Canon EOS 7D.
The kit lens is acknowledged to have optical and mechanical performance is excellent as a kit lens. CameraLabs call this lens as a multi-purpose lens for owners of high-quality crop camera. Ken Rockwell mentioned that the lens is sharp, did not disappoint and perhaps bokeh.

5. Canon EF 24-105mm f/4L IS USM
Maybe this is the only lens series L (luxury) is used as the kit lens). The lens is sold with a full frame camera body Canon EOS 5D mark II.

As the L series lenses, this lens has good optical quality and the quality of the material is very strong. Luminous Landscape calling this lens a lens that is very practical and capable. Photozone wrote that this lens is very impressive and the resolution is also very good.

Reproduction ratio or also known as the magnification ratio (magnification) is one of the most important features of a macro lens.
Before going any further, there is one fundamental question we should answer. What distinguishes a regular lens with a special macro lens? Macro lenses can be used from a distance shooting super close. Macro lens is designed to be the front end of the lens as if it approached the subject of the photo attached. That way, the minimum focusing distance macro lens can be very minimal and in the end, the photo appears to be very large (magnification) by utilizing the properties of optical magnification.
Magnification Ratio 1:1
The majority of the macro lens is designed to give us a 1:1 magnification ratio. Usually a 1:1 ratio is also referred to as life size. While the lens with a ratio of 1:2 is referred to as half-life size. Reach 1:1 ratio when the front end of the lens to the subject of the photo is a minimum specification minimum focusing distance. Magnification ratio and minimum focusing distance can be found at the lens specifications, so make sure you look at the specs before buying a macro lens (and any other things). Continue reading →

Often after buying a good digital camera slr or point & shoot, we are fixated on auto mode for longer periods of time. Auto mode is the most convenient and fast, but does not give satisfaction creativity.
For those who want to “pass and a grade” of the auto mode and want distribute creative spirit into the resulting photographs, it helps us understand the concept of exposure. Famous photographer, Bryan Peterson, has written a book titled Understanding Exposure which described therein eskposur concepts easily.
Peterson member illustration of three elements that must be known to understand the exposure, he named the three as a triangle relationship Photography. Each element in the triangle of photography is dealing with light, how light enters and interacts with the camera.

By the definition of ISO is a measure of the level of the camera sensor sensitivity to light. The higher the ISO setting, the more sensitive we to the sensor light.
To get a clear picture on our camera ISO setting (ASA in the case of photographic film), think about a bee community.
An ISO is a worker bee. If I set the camera at ISO 100, which means I have 100 worker bees.
And if my camera set at ISO 200 means I have 200 worker bees.
Is the duty of every worker bees collect the light coming through the lens of a camera and make a picture. If we use the identical lens and aperture together we set at f/3.5, but I set the ISO at 200 while your 100 (think again of worker bees), the picture had who would finish faster? Continue reading →
