I just recently purchased a z240. I'll have it in a pool to practice next week, but haven't been out with it yet. The manual suggests using a red filter on aiming light. Do many of you do routinely do this? I am guessing I will use a diffuser for macro and fish portraits so it would be easy enough to use the clip in filter.
Thanks for your thoughts on this.
I have it mounted as well.
It is supposed to disturb fishes less with the red filter mounted. I have not really seen any downside so far. So, it is still mounted.

The red filter on the modelling light is meant to prevent the light spot interfering with pre-flash TTL strobe control. It's pretty irrelevant underwater, in my experience.
Using the modelling light as a focus light doesn't work, because the best strobe angles don't put the modelling light on the lens axis. Better to use a focus light mounted above the lens and on-axis.
The intensity of the modelling light is such that, with a filter attached, it's difficult to see much detail in the dark. The blue filter is a little better than the red for revealing what the strobe is shining at.
