Have you even considered changing the ISO sensitivity on your camera? If you don’t know what ISO sensitivity refers to, you may want to consult your camera manual for a base point understanding about that and how it works. In short, changing the ISO setting on your camera changes the sensitivity to light, the lower number that you set the less sensitive to light (and conversely the higher the number the more sensitive it becomes).

Why change ISO?
You may wonder why it is necessary to make change of the ISO sensitivity; in fact, your camera just picked a suitable ISO sensitivity probably the best for your pictures when you are shooting in automatic mode. When you discover the limitation of the automatic mode, you will start to care about what ISO sensitivity should be used when shooting in other modes.

This is useful when you are shooting in different lighting situations - particularly when there is low light and you might not be able to use a flash (you’d bump up your ISO setting in this case), and this is just the beginning why you would want to shoot at higher ISO.

The Inside Story
The only cost of increasing ISO is that as you do it you’ll notice that the “noise” or “grain” in your shots also begins to increase. Thus, the rule is simple - choose the lowest ISO possible for smooth and grain-free shots. The latest generation DSLR cameras today has very nice result at ISO 400 and lower sensitivity, you may consider the output are “noise-free” setup. You have start to concern about anything above ISO 400 … full article.

Since I got my 5D some months ago, and confirmed myself to have 5D serves me as mainstay in landscape and event work, the kit lens 24-105/4 is capable of covering most everyday work, I need some wider and higher speed lenses, enablers for spectacular and creativities in landscape/ low light works. I have considered 14/2.8 II, 24/1.4 and 17-40/4. I finally go with a 16-35/2.8 II lens instead of primes and the 17-40/4 after some careful inspection and refined requirement.

Firstly, it comes with my most favorite focal length ranges and that is a compromised solution - versatile, and high speed for my dynamic style. I say dynamic, that means to be able to run under most environment without the requirement of tripod and minimal time of lens change. (I prefer priorly to have the right lens attached to the right camera and shoot throughout the job). Now the 16-35/2.8 II is always on my 5D and 24-105/4 on the 40D, they are ready to serve my instance requirement.
