I've switched systems many times; Nikon, Fujifilm, m4/3:s, 4/3:s and Sony. I have a "hybrid" photo/video business today. At last I got wiser concerning my workflow and gear that I need. You can read in my signature what gear I have today. Tomorrow I'm photographing a funeral, the family don't want a noisy camera, that rules the Nikon out. I need to be almost invisible, the E-M1 has some sound but is much smaller than the FX Nikon. I'm going to use E-M1 with m.zuiko 45 f1.8 and Fujifilm X100s with WCL-X100 for that wide 28 eq. frame. When I think about it, these are my typical customers; the ones that want discreet work. The other typical customers I have are the ones that want video. There I have the GH4. I got the Nikon for the traditional photographing stuff. But I don't like the workflow with it. For full frame I have the Sony A7II whenever I need full frame. The Sony is also one of the video cameras that I use for wedding filming. The E-M1 with RAW editing in camera and Wi-Fi is my preferred way of working. I've done that before with Fuji X100s (in camera RAW editing). This gives me a much faster workflow, doing JPG:s in camera and at least from E-M1 I can send the photos to my iPad. It means that I can pretty fast deliver the photos digitally to the customer. It is really a way to work faster and corresponds to our time. I'm done with the long editing on the computer! I've have one thing that I miss in my m4/3 system; a good telephoto lens that works inside. I've decided to use the gear that I want to use and that quickens my workflow. I'll sell my Nikon system, I never use it with my heart... And the workflow slows me down... I'll get the m.zuiko 40-150 f2.8 and I'm done. I then have what I want and need! I've seen with my own eyes what different systems provides in photographic IQ and efficiency. m4/3:s with right lenses (with the photographer succeeding in making photos!) provides what customers want and what I as photographer want! I don't need super thin DOF, those seldom succeeds as photos. And I prefer mirrorless over traditional DSLR:s. I like the EVF, the smaller build... For me the mirrorless systems is the way forward. Next week my Nikon system goes, and I get m.zuiko 40-150 for my tele needs. The brand jumping has stopped, I finally see what I truly want and need. To get that wisdom you usually goes through many systems and learn that the grass isn't greener on the neighbors lawn.
