I really, really don't get all they hoopla about mirror-less. What exactly is wrong with having a mirror? As a wedding photographer, I don't find the mirror ever gets in the way of me doing my job. Sure, the mirror makes a bit of noise when it moves, but the 5d3 can be pretty quiet when it needs to.
What benefit would a mirrorless system bring to me? Even if the mirrorless technology was perfect. Even if the af is just as fast as current af systems, why do I need to change things up? Why do I need an EVF? So my battery can drain faster? SO I can use live view all the time, and not be able to stabilize the camera against my face?
If the sensor is always on, doesn't it heat up? And doesn't it heating up cause more image noise?
Did I mention the reduced battery life?
I just don't understand all the hate for the good ol' mirror. As I understand it, mirrorless cameras still have a shutter. Wouldn't a shutter-less camera be more exciting? That is the one component that we always talk about as having a finite life expectancy. And that is the component that limits us to a shutter speed of 1/200 on most cameras when using flash. After the mirror is locked up, its the one making all that noise, and causing a blackout in an EVF. And it is what prevents us from taking stills DURING video recording (without interrupting the video) like you can do on some cell phones now. If there was no physical shutter, wouldn't it maybe be theoretically possible to take multiple exposures from a single exposure just by recording the sensor data multiple times at different points during an exposure? Infinite dynamic range anyone (or at least never a blown highlight)??
What does the mirror prevent us from doing? Don't say it limits the FPS cause I'm pretty sure the 1dx has that all figured out.
Sorry for the rant, but I just feel the desire for EVERYTHING to be mirrorless is ridiculous. Mirrors are awesome cause they can be down when you need them, and LOCK UP for when you don't.
Feel free to let me know if I've missed the point entirely or if I'm not making any sense. /rant
