This is a combination of using an electronic shutter (as opposed to mechanical shutter) and ultra fast processing speed, pure power. The a9 is able to display an uninterrupted live video display even when shooting 20 frames per second.
VIEWFINDER VS LCD PROFESSIONAL
Above 8 FPS, they still have the “slideshow effect.” Though it should be noted that only the top professional dSLRs can even shoot faster than 8 frames per second. The Sony A7riii, a6300 and a6500 can all behave just like a dslr - Live view with momentary blackouts, at up to 8 frames per second. Today’s EVFsīut today’s newest EVFs from Sony no longer have this issue, at least not in the same way. This was a major impediment to shooting action bursts, as you could lose your subject in 1/10th of a second. Thus, if you were taking 10 frames per second, you would be watching a slide show 1/10th of a second behind. As the video feed couldn’t turn on and off 5 or 10 times per second in a burst, Sony cameras would instead show a slideshow of the last image taken. The sensor had to devote itself to a high quality image and then a shutter closing - which required to video feed to shut off. If you were taking a burst of images, some mirrorless cameras could not activate the video feed fast enough between frames. EVFs get momentary blackout when the shutter closes. OVFs have momentary blackout when the mirror flips. Not what would appeal to any serious photographer.Įven some fairly recent EVF’s suffered from something called the “slideshow effect.” An EVF is a video feed off the camera sensor. Many EVF haters are basing their opinion on cheap EVF cameras, or what they heard or experienced with EVFs years ago. Let’s start with some myths about EVF’s based on their history. I may now have a slight preference for EVF’s, but not enough to be a deciding factor for me. OVF/EVF was never a reason for switching. I switched from a pretty good EVF camera (the Sony a99), to a good OVF Camera ( Nikon D750), which I used for 3+ years before going back to a good EVF ( Sony a7riii). The point of this post is to attempt an objective comparison between OVFs and modern EVFs.īefore starting, let me say I’m pretty agnostic. And many mirrorless users say that after experiencing a good electronic viewfinder, they could never go back to an optical viewfinder.
Tweet Optical viewfinders vs Electronic viewfindersĪs mirrorless has been growing, many traditionalists claim they would never give up their OVF, optical viewfinder.
