Who was it who posted about wanting to come back to Nikon, after having gone mirrorless? He posted like a day and a half ago. Surely there are others who have tried a mirrorless camera, and not been 100% satisfied with it, for whatever reasons, and have gone back to a more traditional d-slr setup. The there are the Jason Lanier's of the world, who preach the mirrorless gospel as Sony Explorers of Light (or whatever they are called...Sony Light-seeking Evangelists, Sony Seers of All That Is Holy and Lighted, whatever). Guys like Zack Arias who wrote a huuuuge blog post about why he dropped tens of thousands of dollars on a medium format system with a PhaseOne digital back, but then not that long after, proclaimed the small,light,fixed lens Fuji 100 series to be The Holy Grail...you know, even though it was not a medium format digital camera...Lanier's videos on YouTube are almost comical. Suuuuch a Sony mirrorless fanboy! Astoundingly so.
The internet, and the real world, are full of people who keep looking for that perfect camera setup. Plenty of people on-line, telling you whatever you want to hear, about gear. Smaller! Lighter! No lenses, but you can "adapt" old, sketchy lenses from pawn shops! Focus peaking! Oh...you wanted to shoot soccer games....sorry! yes, the bodies are small, but the lenses are HEAVY! Yes! The bodies are small-ish, but not really smaller than an entry level d-slr, and well, yeah, the "good lenses" are big-ass lenses, but hey-no mirror! Oh...you want TOP-level AF on things that are actually moving, annnnnd you want sequences of things in focus, shot after shot? Oh,well, hey...we didn't really say that in our ads, did we! We said it, "Focuses rapidly! We never aid anything about hit rate, or tough focusing situations...did we!"
I dunno...every camera, and I mean every,single camera, has strengths, and weaknesses. The iPhone 6 camera is pretty good, as long as semi-wide-angle is okay. The m4/3 sensor cameras are okay, but I see their weaknesses at really high ISO settings. Nikon D4s is a nice camera, but its sensor is now low-rezz AND the thing's a flippin monster, size-wise, and it sticks out like a sore thumb. Canon Rebels are small and light. Nikon D3xxx and D5xxx bodies are inexpensive. Fuji X-series cameras are sleek and sexy, but the lenses are surprisingly very heavy! Leica M-series digi's are fantastic, but I cannot afford a $7999 body, and then a $4,999 50mm lens and a $4,999 35mm lens...
No, you are not alone in switching camera setups.
