A standard portrait-length prime, the Lumix G 42.5mm f/1.7 ASPH. POWER O.I.S. from Panasonic is an 85mm-equivalent lens designed for the Micro Four Thirds system of mirrorless cameras. One aspherical element is incorporated within the optical design, which helps to control spherical aberrations and distortions for enhanced sharpness and accurate rendering. The f/1.7 maximum aperture is particularly beneficial for selective focus imagery, and also aids shooting in low-light conditions. Further cementing its place as a versatile tool for portraiture, the rounded seven-blade diaphragm produces a smooth out-of-focus quality when making shallow depth of field photos and movies.

Complementing the optical attributes is a fast stepping AF motor and internal focus design, which provides smooth, quiet, and responsive focusing performance for intuitive handling. The POWER O.I.S. (Optical Image Stabilizer) also benefits hand-held use by compensating for the effect of camera shake for sharper imagery.

Q: 1. does the new bmpcc4k fully support this lens?also what focal length will you get with the lens on the bmpcc4k?

A: Yes, the Pocket Cinema Camera 4K has an MFT Mount and will be fully compatible with this lens. That camera has a 1.9x crop factor, it will be the equivalent of a 80.75mm lens.

Q: 2. How smooth is this focus ring?And how many turns does it take to go from closest focus to infinite in video mode on an Olympus and Panasonic body (preferrable EM1ii, EM5ii, GX85, G85 and GH5).

A: Very smooth. It takes a bit less than 1.5 turns. I have a Lumix GX85

Q: 3. Is there a way to turn on the IS on a BMPCC? or is it just always on?

A: The IS is always on.

Q: 4. Is this lens good for macro photography?

A: For true macro, probably not the best solution. But this gorgeous lens does focus surprisingly close. So “close up” yes.

Q: 5. IS the aperture fixed?

A: If I understand your question correctly the answer is no . You can change the aperture (F stops) f5.6. f8, f16 etc. through the camera settings. There is no aperture ring on this design. Most of the Panasonic cameras have the marking S== shutter priority, A= aperture priority, P= Auto mode where the camera determines the correct combo of shutter speed/ f stop. ( On some of the Panasonic lens there is an aperture ring that you can manually set). The 1.7 marked on your lens indicates the amount of light gathering. Hope this was helpful.

Q: 6. I’ve heard this lens had stabilization issues when mounted to the original BMPCC (micro jitters, IS turning off & on, etc). Is this the same case with the BMPCC4K?

A: We are not aware of any issues using this lens with the Pocket Cinema Camera 4K.

Q: 7. Can this lens fit on a Sony a5100 camera?

Q: 10. If I buy a step up ring for this lens (37mm to 46mm), will I still be able to use the lens hood? Or would a step up ring block the thread from being able to mount on the hood?

A: Once you put on the 37 to 46mm step up ring, the included lens hood will not fit over it. If you put the hood on first, you might be able to get the step up ring on after it, but it would be very fiddly and inconvenient.
