that army of crabs is amazing. Happy with the camera performance?

Some nice pics there!

Really like the first sea dragon and, like Mike, the crabs! The humbugs composition is neat too.

Awesome pics !

As said before me, I really like the sea dragon and the midwater shot with the school of fishs and the sunset !

Does the A7R3 AF do well in macro/supermacro ?

Thanks guys. Happy with the cameras performance for sure. The amount of detail is incredible, you can keep zooming in. I was worried about soft corners and focusing with the canon 8-15, but if you keep a high F number corners are fine. In low light the focus gets bad but when you have enough light the focus is instant. 90 mm macro lens gives very nice pictures but sometimes you wait a while before it finds focus. I have not been using a focus light.

Nice photos.

Please, what configuration do you use for the 8-15 canon? What port do you use? Metabones or MC-11 Sigma?

You comment that the focus becomes a bit slow in low light situations. The A7 III focuses better in these situations than the A7 RIII, have you been able to prove it?

Cheers and thanks for your time.
