Do you know if it uses dual image stabilization (with a GX85 camera), or do the stabilizations of the two work separately? If separately, can they both be turned on together?
I am completely lost. To my knowledge the crop factor applies so long you use FULL FRAME LENSES but in this case the Lumix lens being reviewed in this video is a inherent Micro 4/3 lens and thereby specifically designed for the size of the sensor. The crop factor and zoom magnification does not apply in this case. Ramón
Ramon Lopez in case you have not learned, crop factor applies to all lenses. All lenses are listed in the same focal length terms and must be adjusted using crop fadtod
MFT lenses are all 2x crop. The crop factor doesn't come from the lens, but from the sensor it's designed for. Mft glass is usually smaller and cheaper because there's less sensor to cover
You are right that the lenses are designed for the size of the sensor, but it isn't the crop factor that is affected. There are two issues here which I think are getting confused. The crop factor refers to the field of view on the sensor. Because the M43 sensor is half the size of a 35mm (full frame) sensor, you are only picking up the picture that would be in the middle of the 35mm frame - everything on the outside is being lost. So the image on M43 looks twice as telephoto (i.e. a 50mm lens produces a field of view in M43 that looks like what a 100mm lens produces in 35mm). The second issue is whether the lens itself is made to work specifically with a M43 sensor, or some other format. Panasonic and Olympus native M43 lenses only project an image that fits a M43 frame. If you were to adapt them to a larger format (APS-C or 35mm), you would only see the picture in the middle with black vignetting all around. A 35mm lens, in the other hand, can be adapted to M43. It is made to cover a larger sensor and the extra image will just spill over the sides of the smaller sensor. The rule here is that you can adapt a larger format lens to a smaller sensor (a full-frame Pentax lens will work on a Pentax APS-C body), but you can't go the other direction. A Pentax APS-C lens will have black around the edges if used on a full-frame body - even though the mount is essentially the same and the lenses will fit. The same thing would happen if you tried to put a M43 lens on, say, a Sony APS-C body.

crop factor is 2. So its 90-350mm in full frame. I had 45-150 because of weight and size. Those two lenses are similar and very good.
Interesting, very educational. I'm big into photos not videos and this was a perfect education. Thanks

If you are zooming in while shooting video, does the object stay in focus? (or is it noticeably trying to find its focus)
So the elements are all internal, right? ie the lens doesn't extend when it zooms?
correct
