DSLR's are officially dead.

Well, he says if you are a professional, making your living from photography, then you should be using the most current, best technology out there. He also said that if you are an amateur, hobbyist, etc., then what he has to say does not really apply to you.

As I recall, and he actually shows an old clip in his new video, he hated MILC, and said so many times, but he now says mirrorless have improved so much and has so much more to offer, that his thoughts have totally changed. According to the video he sold all of his DSLR's, including his D5.

Link for the video to follow.

Comparing a dSLR to a MILC when both use identical sensors and processors, the images will look the same when the same lens and settings are used to test each.

But that condition is unlikely to occur!

There are many advantages to mirrorless cameras that improve the photographic experience. Paul Sager alluded to some of them above. My take on it is that the experience is DIFFERENT. I can use my camera in ways I never could use a dSLR or SLR or TLR. On the other hand, dSLRs still do a few things better than MILCs or film cameras.

The mirrorless camera I use is both a very good stills camera and a very easy-to-use, full-featured 4K video camera. It makes my job as a content creator (documentation and training materials) very easy. I can record the same content as still photos and video, without having two different camera setups, and with about half of the time, relative expense, and inconvenience that entailed about 15 years ago.

If your current gear does what you want or need it to do, keep it. When you see an obvious need to change, such as some must-have tool or operational advantage your current gear can't provide, then it's time to give mirrorless a close look. (Notice I didn't say, "switch." A switch might be inappropriate for some.)

Always keep the idea in mind that the medium CARRIES the message. While it may "color" it, it is supposed to transport it. So don't let gear get in the way of the images you are making. The photographer makes the photograph. The camera and lens just record the image. There is a HUGE difference. A five-star chef does not need industrial strength pots and pans to cook dinner at home. But (s)he may have them.
