I am Canon user for long, and recently I have my Panasonic setup slowly build up. I like my L lens and my G9 ….

one day, someone told me . I actually can use all my L lens on my M4/3 G9 . Due to busy work schedule, I dont have time to look into it until last week. I finally have time purchase one online and test it last 2 days … I did very quick test more testing would like to do

1. AF accuracy

2. AF performance

3. can both Len and Body Image Stabilizer work together as Panasonic Len ?

if all above work well, than I would prefer to use my G9 on my Canon EF500mm F4 IS2 ….

1. pre-burst mode for G9

2. Dual IS – IBIS and Len IS

3. internal 4k , 30fps 10bit log (and future I can get GH5 for more)

4. 180fps slow motion

etc

so TEST1 – AF performance

I try both 500mm (outdoor), 1635F4IS (indoor)

BOTH give me very fast AF .. and very accurate (no fine tune done on my adapter). the new eye AF work fine with human , but not really work on big bird (buffy Fish Owl) and small bird .

TEST1 (click the picture for actual size view)

– Adjust contrast, Saturation, noise reduction
