hi to those who own this lens.
a quick question as i just rented this lens today, went to ubin to take some shots, i realized a few things:
1) when going close to my subject, not sure its due to the min focusing distance, the focus is trying very hard to focus, when i moved back abit, the focus managed to capture the subject immediately, but sometime, its still trying to focus, in and out in and out
2) in macro mode, we cannot control the aperture? I tried to adjust but it always changing the aperture, I'm in manual mode. Cannot manual overwrite?
3) I find when going in closer to subject, the focus is not really that fast. Wonder if its due to something which i need to set or perhaps use manual focus instead
