People often get lost in analyzing the single spec sheet data but the OM-1 value is much greater than the sum of it’s parts! Here are three conclusions that give you an idea how good the camera is:

Amateur Photographer concluded:

Without doubt, the OM System OM-1 is the best Micro Four Thirds camera currently available, and goes beyond what you would expect from a £2000 camera in terms of subject detection AF, high-speed performance, and the sheer number of useful shooting features available.

Imaging Resource concluded:

The OM System OM-1 makes a great first impression for OM Digital Solutions. For longtime Olympus fans, it’s comforting to know that everything people love about Olympus Micro Four Thirds cameras is still here. In fact, not only is everything still here, it’s better. The OM-1 is more impressive than any previous Olympus camera in just about every way.

ThePhoBlographer concluded:

Through and through, the OM System OM1 is a fantastic camera. It will perfectly suit the needs of most professional photographers who don’t need super high megapixels. Better yet, it’s also great for passionate photographers who just want to have fun. There are lots of fantastic lenses available for it and lots of creative choices photographers can make. And don’t forget about the world-class build quality it has. Combine all that with the small package, incredible battery life, and more!
Is it a perfect camera? No. But most of what needs to be done with it can be done through firmware updates.

Let’s not forget OM system also announced two new lenses. Here is a short quick look from Peter Forsgård:

CineD reviewed the new GH6 and concluded:

Let me start by asking if a Micro Four Third camera still has a valid place in today’s market. My answer is, absolutely yes, but mainly because of the vast amount of lenses out there. Originally, MFT had the upper hand when it comes to camera size, but in modern times, this advantage has disappeared. While it’s great to see Panasonic committing to this format, I’m sure it is not easy to develop two separate lines (MFT next to full-frame) considering the costs involved. I’m very curious to see how this will evolve throughout the upcoming years.

In regards to the LUMIX GH6 itself, I really like what Panasonic did here. One noticeable improvement is the overall color “pipeline”. If in the past I highlighted the fact that images are hard to grade (too reddish) and “too smooth” (Extensive noise reduction), now it is a think of the past. So all in all, It is a great overall performer.

I also want to dedicate a short paragraph to OM System, a direct competitor, which coincidentally, brought their OM-1 on the market at the same. Although I did not have a chance to test their new camera, it seems as if there is very little to compare, besides the sensor size. If you are a filmmaker, the LUMIX GH6 might be the wiser purchase over the OM-1 as both are at the same exact price point.

Talking about price, I really wonder how the filming community will react as Panasonic is currently running a special promotion at B&H and one can get the LUMIX S5 full-frame camera body only at $1898, or, with a 20-60mm lens for $2198. This aggressive pricing can only confuse potential customers and result in them buying nothing. If Panasonic cares about selling as many possible GH6 cameras, the advantage should be definite.

Jordan Drake talks about the GH6 and concludes:

Aside from very low light shooting, capturing the most high contrast scenes and when I need the absolute shallowest depth of field, the GH6 outperforms my current favorite video camera, the S1H. The headline features like 5.7K unlimited recording and 4K/120p certainly excited me, but the main things that make me really want this camera are the smart inclusions like the 4 channel audio, punch-in focus while rolling, and 100MP handheld hi-res capture with motion correction.

This camera will make me leave the S1H at home for the majority of DPReview TV shoots, and that means Micro Four Thirds is alive and well.
