Positioned as the perfect portrait prime, the black M.Zuiko Digital 45mm f/1.8 from Olympus is a sleek 90mm equivalent lens for Micro Four Thirds mirrorless cameras. The short-telephoto focal length pairs with a bright f/1.8 maximum aperture to benefit working in low-light conditions and also offers greater control over depth of field for producing selective focus effects. The optical construction of the lens incorporates two extra-high refractive index elements, which help to reduce distortion and spherical aberrations in order to realize notable sharpness and accurate rendering. Additionally, a Movie & Still Compatible (MSC) autofocus system is employed to deliver quick, quiet, and precise focusing performance to suit both video and photo applications.

Size Matters

In this case, the size doesn't matter. I also have a FF system, and I compared it to this MFT version. Both are excellent, but the size and weight are much better with MFT. I really like it.
Interesting lens

I haven't had the lens for that long so I don't really have much evidence to evaluate it with. It's a very interesting lens and I'm still trying to figure it out.

question
CAN THIS LENS (AND THE OLY 25MM 1.8 LENS) WITH A CERTAIN MOUNT FIT ON THE NEW SONY 7AR2 CAMERA ?AND DO YOU LOSE OR GAIN ANY THING WITH THAT ADAPTER? PLANNING TO GET IT FOR MY NEW GH4.
Micro four thirds lenses will not work on the Sony a7RII. B&H does not carry a M43 to Sony E-mount adapter, nor am I aware of one on the market. The M43 lenses, such as this 45mm f/1.8, are designed for a sensor half the size of the a7R II. So, even if you were to find an adapter, the lens wouldnt cover the entire full frame sensor. An optic would also likely be needed in order for the lens to retain focus at infinity, as the difference in the register between the two mounts is just over 1mm.

Is this the lens compatible with the Inspire 1 x5R?
Yes, DJI Inspire 1 v2.0 RAW Quadcopter with Zenmuse X5R 4K Camera and 3-Axis Gimbal has a micro 4/3 lens mount. Any Olympus micro 4/3 lens (Olympus M.Zuiko Digital 45mm f/1.8 Lens (Black)) will be compatible with this Gimbal.

question
Is this good for shooting video on the GH4 since it doesn't have manual focus?
It does have manual focus, but it is focus-by-wire. Because of that it does take some getting used to, and I greatly prefer a lense where you physically turn the glass, but you will get used to it if you use it enough. I don't use it as often for video where I am pulling focus, but it looks great for set shots such as interviews where you don't have to change the focus much if at all.
