Is the 45mm lens on a micro 4/3 worth it?

I have an OM-D EM-10 IV with the AOI Octo housing. Bought the Olympus 60mm lens and port and will shoot with them for first time in Cozumel in 2 weeks. I also have a +6 diopter and flip mount.

I have been watching Alex Mustard's web series on UW photography. He suggests that, besides the 60mm lens for macro with these cameras, the 45mm is also useful for a wider range of subjects, e.g. larger fish down to nudibranchs. What's your opinion? Obviously, I will try out the 60mm in Cozumel, but do you think the 45mm would also be worth having? If so, which port or extension would I need for my system? How is autofocus with that lens?

the 45mm

Are you talking about the Panasonic 45mm macro lens or something else?

I meant an Olympus 45mm. But, your question made me look. Maybe there isn't a good OM 45mm macro lens, huh?

No, not "macro." There is Panasonic 45mm macro lens. I believe that om has a 45mm lens but it isn't macro.

There is a very nice Oly 45 mm pro lens ($900) which is great topside but useless underwater, the max magnification is 0.1x and the minimum focus distance is 20 inches (50 cm). The Panasonic/Leica 45 is a great lens, really wonderful IQ and great bokeh BUT it does not focus fast. I use the 30,45, 60 and 90 macro lenses, each has a place).

Can you give examples where you use one and not the other please?

Yep I have that lens lying around unused - M.Zuiko 45mm f1.8 (90mm*)… maybe shot less than 200 snaps with it before I discovered I prefer the IQ and framing with the M.Zuiko 25mm f1.8 lens more. Never tried taking it UW though…

30–blackwater (but I’m a heretic and prefer 12-40)
45–no idea
60–didn’t use it last time, didn’t bring it this time
90–glorious glass
