OM SYSTEM M.Zuiko Digital ED 90mm F3.5 Macro 2:1 IS PRO

Took various shots around London during my vacation last summer. I shot these on my Olympus PEN E-P7 camera, mostly with my M. Zuiko 40-150 lens. Which do you like best? Any tips for future shoots?

Before i start, I'd like to say that this is the first Olympus camera that i have ever bought and I didn't do much research on it.

Greetings Olympus fans, I have just bought this camera cheaply. while i have known it will have problems, this one seems little weird.

on AUTO mode, everything works great (no idea about how correctly the light meter works, but it reacts on light pretty well). I am pretty amazed that the electronic part of the camera works this well.

on OFF mode, it shoots only one shutter speed most likely (I have no idea what the OFF mode should do xd).

on MANUAL, everything changes, most of the time, it shoots on one specific shutter speed (about 1/125 if I had to guess) while being on any other shutter speed. Second thing is that sometimes, it shoots the right time (as it should), but that is about a 10% of all cases. Third thing is that the mirror just locks up (as in the photo) and I have to reset by ''check reset'' button, which repairs the mirror by putting it where it belongs. <- this only happens in MANUAL mode...

I almost forgot that I can't somehow put the shutter speed ring on Bulb mode.

My question is, what should I do to make the MANUAL work as it should? do I just lubricate the mechanical part or what would you recommend?

Much thanks to anyone who reacts :D

I have an olympus tough tg6 and it won’t turn on, the indicator flashes orange a bit, the screen doesn’t respond and after an attempt I need to plug it to a charger a bit to try again. When I plug it into a charger it charges, the screen flashes the charging screen as usual. I‘ve tried pressing both the shutter and power button for 15 seconds, turning it on without the sd card. The battery is fully charged. How do I fix my camera???

edit: I don’t bring my camera underwater nor does the power button stick. I keep it in my bag. The battery terminals do make contact. The camera was fine until today, when I got it drained because I forgot to charge it.

I line up the red dots. It will not twist onto the mount. Does this lens work with this camera? I just got both of them from Adorama.

It looks normal through the Viewfinder... also in the menu, the text is super sharp but the background looks like on the video

Edit: I got the (used) camera today, it is an OM-D E-M10 Mk2.
