This is the "normal" image off the em5 mark 2 sensor. It has nice or reasonable resolution but there are times it is not enough.
This is the High Res mode which I think is an 80mp photo that in this camera body is designed to be used on a tripod. I was curious to how much detail it would have in an image like this so I did a massive crop in to see what it would look like.
I think it retains detail quite nicely. I should have used the smallest focus box and focused on the front beads but this does show there is resolution left. While there is a lot of uses that this mode on this body is not designed for but I can see some uses for this in the food photography genera. I do need to do a bit of research and see if there is a way to retain a raw file or if it is jpg only. If that is the case it is not a deal breaker it just means I have more to get correct in the camera and less room to be lazy.
This is making me think could you imagine what detail you could see with say the Sony A7R mark 4 or the Canon R5 bodies if they had this mode. I think the Fujifilm 100mp GFX body does have something similar which would be beyond a huge file and also the details when you get it right would be insane. Anywho I am dreaming lol. Just a quick test of a function of the body of the camera.
