So now that Mirrorless is here, what is the features and functionality that makes this technology talk of the town? Why does it revolutionize photography and obsolete DSLR’s, and very importantly, are there no drawbacks?
Since features generally are used to segment the camera models and the market, this discussion is about what Mirrorless currently can do and what it will soon enable – across all brands and models pending on what the makers decide for each of their cameras. Also, it’s not at review of the current quality of a given feature. Since Mirrorless enables new functionality, If the feature has not already been perfected to DSLR level maturity, it will be very soon.
Please note this article is about photos - not movie mode - so I will not address what mirrorless brings when it comes to recording video. The movie mode advances are far bigger and more revolutionary than the changes to photo mode, so if movies are your thing, mirrorless is a no brainer.
But first, let’s get the drawbacks of Mirrorless out of the way. By drawbacks I mean things we are used to and expect based on using professional tier DSLR cameras. In reality there is only one real drawback plus a pretty annoying maintenance issue:
- No optical viewfinder (OVF). For many people the loss of the optical viewfinder will be difficult or perhaps even impossible. A VERY good screen/electronic viewfinder display will still be a representation of what the camera is seeing, with refresh delay, possible color mismatch, lighting “interpretation” and so on. No matter how many gains and advanced features that display will bring, it’s still not an optical real time view of the world.
- Mirrorless cameras is by definition a lot more prone to sensor dust specks. This is because when sensors are powered up they electrostatically attract more dust. In mirrorless it’s powered on during all activity (composing and so on), and for most models it’s never hidden behind a shutter.
