To get 2000mm from the 100-400 on a 16mp G7 the camera must either shoot in 720p video and grab a 0.9mp frame, or 2x TeleConvert:on with Ex Small 2mp jpg (1600mm EFL ) and crop to 0.9 mp.

On the Gx8 it should be more but not 5mp I don't think.

I'm not understanding a 16 vs 5 mp comparison.

Read my first post above. To get a 2000mm FoV from a 16MP m43 camera with a 400mm lens (800mm equiv FoV) you need to take a 5MP crop from the 16MP image.

Or you can use an 800mm and a 1.4x TC and that gives you 2240mm at full res of the m4/3 sensor.

All the best and just saying

i wonder how the TC would affect the IQ? Someone needs to test immediately!

Already been done several times on APS-C and m4/3 Its pretty darn good !!

All the best.
