The lock issue is due to the hybrid AF implementation. The camera will decide whether to use the legacy AF algorithm based on the lighting conditions. This is the reason you experienced big differences between f/1.8 and f/4 lenses. Current AF implementation produces a large amount of false positives when AF seems to be locked.
@@quagmire321able Unfortunately it is the reality about the AF implementation of S5II and it is stated in the manual as well. I tested Canon R6 MK2 for about 2 days using RF 24-105 F/4 and RF 24-70 F/2.8 lenses. To be honest, I had no effort to focus on any object, human, moving car ...etc. and I almost had %100 focused results. The difference is HUGE.
@@engineer4862 ahhh... so it's a S5 II issue, I guess it's not too bad for a 1st gen hybrid AF then but they still have a lot of catching up to do. BTW, I found the AF works much better with the primes on the S5 II. I am prime shooter, so I am kinda ok with that 😛
Great review
13:48 At least now you have somewhere to vent your miseries. 😢

Really? I have done the same test with a couple of Sony cameras and neither of them exhibited the same behaviour with f/4 lenses

14:10 Did u read the instruction manual? hehehe 😅
Yes, I did and I reached out to Panasonic for a solution, they said nothing.
