Note: I love DSLRs, but I understand that it's a unsusteniable model.
Best regards,
Sustainable for who?
It's the other way around actually. DSLR is probably the sustainable model.
When I look at what fails in a camera, at least in my experience, it's:
1. Electronics, including sensor
2. Batteries
3. Mechanics
A couple of weeks ago, I had an odd experience with one of my mirrorless cameras, a Panasonic GX8. The colours in the viewfinder were suddenly washed out, pale and detail rendering looked like something out of a romantic C movie. The next day, it seemed fine again, but it made me wonder how long these viewfinders actually last. One thing is for certain though: replacing them is probably not an economical exercise to consider. Like most modern electronics, they are most probably designed not to be repaired. It's cheaper that way, at least as long as electronic corporations are not held accountable for the junk they generate.
One of many great things with optics and mechanics is that they are relatively easy to repair and replace. And even if some defect occurs, there are often temporary workarounds available. In a world that drowns in used plastics and electronic junk, that should have been a priority.
I like my mirrorless cameras and my other digital cameras too, but it's interesting to see that after nearly 50 years of SLR photography, I've had 1 shutter replacement, a D80 that was way past its "eat by" date (It also needed its top panel replaced.), but countless electronic failures, all except one with digital cameras. After nearly 50 years with analogue cameras and 14 with digitals.
It's interesting also to note that according to CIPA statistics, from January to October 2017:
- There were 87% more DSLR cameras than mirrorless cameras sold.
- The value of those DSLR cameras was 63% more than that of the mirrorless cameras
Mirrorless is catching up of course, but it's been 9 years now. That's a long transition for a technology that some call disruptive. I think we'll still have DSLR cameras in 10 and 20 years from now. Cameras like the D5600, the D7500 and the D750 show that DSLR bodies don't need to be large and heavy, and after 9 years using mirrorless cameras, I still prefer optical viewfinders for a lot of what I do. What Nikon needs to do though is pull out all the stops. The D750 replacement should have a viewfinder as good and as flexible as the one of a D850. The viewfinder is the single most important component of a DSLR camera, and in 10 years, it might be the only component that sets it apart from an iPhone, at least from a mainstream user's point of view. It's with that component I compose my photos. If it fails, I don't have a camera. Most of the time, glass don't fail.
