Tips of the Day: How to change DSLR lens quickly?

In an event it is impossible to take the picture with the only lens. Sometimes we have to change it. For example, the wedding ceremony photo shoot session which some photographer like to take candid pictures of the people. It is imposible to take a candid pictures with short zoom lens or kitlens like 18-55mm, 28-80mm and 16-80mm. Except when you have the wide telephoto lens like: eg. 18-250mm, 28-200mm, and 28-300mm. To change the lens, you will need to follow this 4 simple steps:

1) Hold your camera in your left hand as shown in the upper left part of the top photo. Approach the lens as shown with your right hand open and the right forefinger extended a little.

2) As seen in upper right, when you close your hand around the lens, depress the lens release button with the left side of your right forefinger.

3) Moving onto lower left, rotate the lens clockwise (for Nikon, reverse for Canon & Sony) and let the forefinger slide along the still-depressed release button.

4) Finally, as seen at lower right, the lens slides smoothly off of the camera and leaves with your right hand.

Hope this helps! Thanks for viewing!

What a shocking wedding job! A last minute call for this job which is started on Friday (26 March 2010) for Akad Nikah photoshoot. Very sporting couples, but that day the newlyweds and photographer all tired due to very hot weather. I'm only using 58mm f/2 and 70-300mm Telephoto for outdoor shooting. Enjoy the picture, stay tuned for more updates!

What is Aperture?

Aperture is ‘the size of the opening in the lens when a picture is taken.’

When you hit the shutter release button of your camera a hole opens up that allows your cameras image sensor to catch a glimpse of the scene you’re wanting to capture. The aperture that you set impacts the size of that hole. The larger the hole the more light that gets in – the smaller the hole the less light.

Aperture is measured in ‘f-stops’. You’ll often see them as f/number – for example f/2.8, f/4, f/5.6,f/8,f/22 etc. Moving from one f-stop to the next doubles or halves the size of the amount of opening in your lens (and the amount of light getting through). Keep in mind that a change in shutter speed from one stop to the next doubles or halves the amount of light that gets in also – this means if you increase one and decrease the other you let the same amount of light in – very handy to keep in mind).

One thing that causes a lot of new photographers confusion is that large apertures (where lots of light gets through) are given f/stop smaller numbers and smaller apertures (where less light gets through) have larger f-stop numbers. So f/2.8 is in fact a much larger aperture than f/22. It seems the wrong way around when you first hear it but you’ll get the hang of it.
