Here we’re going to talk about the pros of switching over to a mirrorless. I shoot with the Fuji X series, and I adore it completely. Not to say that there are things I miss about SLRs, just that there are huge benefits of shooting the (relatively) new type of system.
EVF – The electronic view finder has its flaws, like lagging (which in recent days it’s near no lag). However if you just simply look at your subject with both eyes it’s not that difficult of a problem to overcome. The benefits outweigh the cons. Seeing your exact exposure and histogram inside the viewfinder is, in my opinion, one of the major reasons you should switch to mirror less. This ability lets you live view the exact photograph you’re going to be taking. No more fiddling with aperture and shutter speed or remembering the sunny 16 rule. It’s right there in front of you and you don’t have to wait, and you know your exposure is dead on with the histogram sitting pretty right in the corner. I can also think of no good reason why not having all of the exposure information right in front of you, including focus, being anything but a good thing.
Weight – Having a camera be capable of giving 16mp+ and being as light as a point and shoot or a cheap dslr is incomparable. being able to shoot with one hand and not having to worry about dropping it is such a load off your mind. Also I used to shoot street photography with a dslr and that is equivalent to lifting weights for a few hours. Even if you have a strap it’s still a strain on your neck or shoulder. The mirrorless systems are compact and light and still pack a punch.
Smaller Lenses – It’s not just the low weight of the body that is a great benefit but the lenses are also smaller due to the distance from the rear element to the sensor. A similar lens can be half the weight going from a dslr to a mirrorless. The only con is that mirrorless being new, there are a lack of options for lenses and they cost sometimes 4 times as much. The Sony 50mm 1.8 is around $250, where Nikon or Canon, they’re just over a hundred.
Size and shape – most if not all mirrorless cameras look unprofessional. They look like tiny point and shoot cameras. This sounds like it would be a con but when you think about it, it’s a huge advantage over DSLRs. “Hiding” the camera from your subject is key when trying to grab that candid street photo or getting that genuine smile from a subject when doing portraits.
They’re quiet – This also seems like not a big deal but shooting street, portraits, or fashion you never want to let the subject know the shot has been taken. Mirror slap is loud and revealing. Mirrorless cameras only make a shutter noise and more than 5 feet away and it’s completely silent.
Longer handheld exposures – With out mirror slapping your camera like its the eighties trying to give you a high five; you need not worry. Granted it’s only a stop or two depending on how good your still life impression is. That stop might be the difference between a keeper and a unusable because of motion blur.
These were just some examples of the benefits mirrorless cameras have over the ever so recognized DSLRs. There are many more but come on, most people didn’t read this far because TL;DR.
