New lens test: Olympus 25mm f1.8 and 45mm f1.8 on the DJI X5

I thought the longer micro four-thirds lenses would be too much for the DJI X5 gimbal used on the Inspire 1.  It is a lot to ask, certainly in my opinion, stabilising effectively a 100mm (35mm equivalent) lens adequately for video.  The crop factor on the DJI X5 is 2.3x, the same as it is on the Panasonic GH4, so the Olympus 25mm becomes 58mm and the 45mm just over 100mm.

The first clip on the test footage above is the 25mm lens and the rest are captured using the Olympus 45mm.  The perspective compression or foreshortening using the longer lens is amazing.  I use longer lens all the time, by somehow used in the air on a drone that compression and reduction of distance looks greater.  This will certainly be a very useful lens when needing the extra reach, whist maintaining the 50metre distance from people, structures and vehicles in accordance with our and most other operators CAA ‘Permission of Aerial Work’.

All of the footage captured with the Olympus 45mm f1.8 lens was stabilised in Adobe Premiere, although you would have been hard pressed to tell the difference between the before and after footage.
