i see , i use mostly manual lenses on my a6000 and my a7II , sometimes reversed lens like the rokkor 28mm 3.5 and sometimes the helios 44-2 58mm with extension tubes , sometimes i use the old Panagor macro converter with the rokkor 50mm 1.7 they all have their own bonuses. and sometimes the Sigma 105mm macro lens but for the real close-up insects the reversed rokkor 28mm is still the winner due to the high magnification .
