Commonly, People use telephoto lens to zoom a subject from afar, but actually there are so many other functions of it.
This article will discuss all about this lens.
First of all, lets we find out the definitions of this telephoto. According to me myself, a lens can be considered as telephoto if it has a focal length of 60 mm or more which includes the lens standard or lens width.
There are two kinds of telephoto: one is a telephoto lens that cannot zoom (fix) such as Canon EF 200mm f/2. The other one is a zoom lens like Canon 70-200mm f/4 L. lens with zoom is more multi-functional but one without zoom normally has maximal opening which is wider and small in size. There is all around lens that has got wider focal length than telephoto for example 18-200mm lens.
Let’s uncover the characters of telephoto lens. Read the rest of this entry »
Many beginner photographers think that a good photo can only be obtained by using a sharp lens that produces sharpness right to the edge of the frame. There’s truth in that, but it’s not always so. A sharp image without a sharp message doesn’t amount to much of a photograph. What would make a better image would be one that conveys a clear message and sparks an interest.
In photography, sharpness isn’t everything. The meaning and depth of story-telling is more valuable in a photograph. The following are a few examples of how mis-focused photographs can work. The mis-focus doesn’t hinder the photo from its story; in fact, it creates a bolder statement.

In the previous post, we talk about auto focus, how it is used and what its strengths and its weaknesses. In this article, we would like to cover details on some of shooting conditions where the auto focus is not the good option and the manual focus is the one that should be chosen to get expected results.
1. Macro/Close Up
When you do macro/close up photography, the distance between the lens and the object can be very close and the depth of field can be very shallow for about few millimeters only. With such close object, the focus can be very difficult when you use auto focus. For instance, when you shoot insects and want to get the focus of their eyes and the auto focus is one in charge. You will find the focus that falls on the eyes is possibly not sharp. For such case, you will need the use of manual focus instead and move the ring by yourself to get the intended part.
2. Low light
This condition is pretty common where the auto focus will not work properly because the lack of light can make it very difficult for it to find the object unless you use AF-Assist which usually disturbs the object. For some kinds of lighting, your eyes can be better to find the object rather than the camera. When the LCD blinks a message “Subject is too dark”, actually, our eyes are still able to find the focus through viewfinder. So you may co-operate your eyes with the manual focus and you will get sharp image on the objects you want even in low light condition as well. Read the rest of this entry » .
