I currently use an a7R III with a 90mm macro. Unless I'm in bright sun, I usually need to use my flash. I've had my i40s since 2016 and I like the size and the physical settings (not having to use an LCD and push buttons like the old Metz that is finicky with the adapter for the new hotshoe so I don't use it).

How long should I expect one to last? No doubt I've used this more than the old one, but even from the beginning I've had issues. The first one I purchased right before a trip, and had problems wit it not working properly on the trip so when I got back I exchanged it.

Now, since around the beginning of the year, it seemed like even after using it with fully charged rechargeable Eneloops, with a DIY diffuser, TTL, after a while I'd start getting underexposed photos. Even setting it to the max or fiddling with the diffuser, they'd be too dark. After some time I tried changing the batteries when that started to happen on a trip. That seemed to help some but that didn't fix things.

I've been trying photos with the head at 45o, which I haven't done before, for maybe the last month or two. I've had to fiddle with the diffuser. I don't know if all flashes are like this, but with the head in other than normal position, it doesn't do TTL. It's the same though, often too dark.

I've been taking photos with the lens at 1:1, manual focus, to capture details of different bees from my yard (chilled and on the white lid of the container) so the settings and position are consistent, I haven't moved. Besides many shots being too dark, now some are way too bright. I'll have to take at least 3 shots in 1-2 minutes because with everything the same, one will be too dark, the next too bright, then it's ok. Or not.

Tonight I tried to take some moth photos at the porch light. In addition to the previous issue, now it won't fire a lot of times. The light has been green. I also tried it in the normal position and without the diffuser, same thing.

Do I need a new i40s, a new model, a different brand? If either of the latter two, what would be similar, a smaller size, the equivalent power from 4 AA batteries, and preferably physical settings? Also something that could use third-party wireless transmitters, since I can't with this one.

TIA

I have a Godox TT350 - haven't used it enough to say anything on the reliability of it. But it is small and cheap. It has a LCD though

Did you look at a ringlight? Sounds like it is more suitable for your kind of pictures.

No, sometimes it's awkward and already tight to get the lens close enough. That's why another bug photographer I know said he hates his ring light.

Hmmm, they are made for this situation and other photographers like them. Your mate might not like them, does not mean you're the same. It is up to you.

I do not do bugs, so I looked at some instructional sites, might be useful for some people:

How do you like that Godox so far?
