For a nascent photographer, its become impossible to grasp the full potential of hi-tech DSLR camera. They have to play around its different setting to get a basic idea of generating optimum images. Furthermore, when they switch to manual focusing, their objective of snapping the crisp images get shattered.
The autofocus is standard setting developed and encoded by the company to cater various focusing conditions. The autofocus offers an advantage of eliminating the need the tedious manual focusing. You target the subject and it automatically focuses on it which gives you clear image without any hectic interference in the camera setting.
Then why do you need manual focus?
The reasons are many and a first and the foremost factor which provoked the need of manual focus is "macro" shots. While executing macro shots, the depth of field (DOF) become so shallow most of the times. It leads to focus peaking condition in which camera was not able to focus on one object. The focus point becomes distracted and photographers end up with getting sub-par image output. The autofocus works like a hell in this situation.
Another condition is focusing on a subject in a crowd of similar objects. The modern-day DSLR is equipped with cutting-edge lenses but the algorithm part is somewhat not well synchronized enough to snap that perfect shot. Most of the times, camera find it hard to identify the target subjects like blades of grass.
In case of landscape shooting, the autofocus generates a blurry image with focus render on the wrong object. To get the crisp output, you have to deal with manual settings in which you alter the key factor like aperture, ISO, white balance, and manual focus peaking to get the perfect shots.
In the low light scenario, autofocus is not able to deliver the good images. However, in this case, camera aperture can play a huge role. Higher the aperture, brighter the shots. Meanwhile, in the low aperture situation, switch to manual mode, crank up the ISO little bit, focus until object becomes sharp and click the photo. Done!
Moreover, if you want a subtle focus transition during the filmmaking then, you can opt the wireless follow focus system as an optional accessory. This product has raised the bar of traditional filmmaking practices. This product offers a diverse range of focus transition with its belt drive and gear assembly units. All this hardware is assisted by the wireless trigger which is used to control the focus speed. Moreover, you can also alter transition speed with respect to the pressure sensitive wireless trigger.
Steps to get subtle manual focus
1. On the lens side, switch from auto mode to manual mode.
2. Precisely turn the focus ring until the target subject sharpens.
3. For the close-up shot, zoom towards the object and switch the camera to viewfinder mode.
4. Focuses until the subject become absolutely sharp
5. Tap the click button
