Hi, I updated it, everything is working fine for me, did a lot of macro (not underwater) ...

Did you see/experience any improvement in the focus department?

no, unfortunately not, autofocus, as special cont autofocus is still very unsatisfying for me (macro use). What is new is, that you can create your own customized focus points

Hi Susa,

Could you give us some more details about the problems you encountered with the AF in macro? You are talking about shooting on land and in photography, right? No video?

Hi Davide, many thanks for your interest!

Yes it's only with stills. Before a few weeks I posted about it, using cont. autofocus without AI object detection doesn't work precise enough for macro work, on land or underwater makes no difference. And its also not about too less focus light or bad autofocus conditions. I try to explain, please excuse my English but I'm no native speaker :-) :

Please see picture one, this is my motive, setting the focus point (small) to the red mark, which I want to focus on, second picture is where my focus ends up in blue, when I move my camera while focusing. The pictures are only for illustrating what I mean. In reality the output is, that for example the eyes are not sharp. This happens not with A1, A1 II, A7V, but with A9 III it's the same problem. I already talk with Sony about it, they had the explanation that the sensor of the A7R5 is too slow, hmmmm, but that can't be the case for the A9III, we tried it in a shop together with a Sony guy and with different cameras, Canon R5 was the best result :-( .

Would be really interested how your thoughts are! I have the A7R5 from beginning on and I think at the beginning this was not the case, it worked much better and I had better results.

Hi Susa,
I replied you in the other thread and as I wrote, I'm not a Sony user and this is a very specific situation. try to open a specific thread so that other users notice it and can give you their contributions.

Ciao

For some reason, i seem to have this exact same thing. A1ii+100mm.

Shooting nudis, initial focus on rhinopore and then it just buggers off to grain of sand or a spot on nudi.

Didnt have any of this on A7RV+90mm, always spot on.

Maybe mods can break this into own thread?

I have it with the 100mm Sony macro (and other lenses like 70-200 f4 macro) on my A7RV. It is very easy to reproduce.

Addition of a statement

I shoot quite a bit of macro, not a Sony user however I think I can offer some thoughts. When you are life size, your depth of field is very small - around about 1mm, so it stands to reason that you need to be able to compensate for the fact your subject might be moving, you may not be totally stable and surge and current might intrude into the picture causing both you and your subject to move.

My regular UW shooting is done in Botany Bay south of Sydney, this site is inside the heads but rather exposed to ocean swells which can produce varying degrees of surge and also subject to tidal currents, one of the subjects there is the pygmy pipehorse and swings slightly out of sync with the surge. My technique with that is continuous AF, holding down the control as required while framing and waiting for it to swing into position. The AF chases and swings around quite a bit as the subject moves out from under the single small AF point. The trick to me seems to be patience waiting until the subject is in position then activating AF and if needed half pressing the shutter to engage IS which helps hold the AF point on target. The shot is taken when I can see positively that the AF has grabbed focus.

The point is that IS can account for side to side, up and down movement, bu the AF needs to deal with our back and forth movement, so anything you can do to minimise this will be a great help. How well can you hover? DO you use a pointer or grab a safe handhold on bare rock to stabilise?

You talk about moving off target is this because you/the subject moved or are you saying the camera decided that another object was better to focus on? I used to use C-AF plus tracking but have reverted to C-AF without tracking using the smallest AF point, then it's up to me to stay on the target and I find I can make this work, certainly don't get every frame sharp, but what I get is acceptable.
