A few G7x ii setup and LR tips

Re: A few G7x ii setup and LR tips

Something changed for me.  When I first got the cam, the corners/edges at 24mm f1.8 looked really awful.

I turned off the internal ND filter, and the corners seem to have gotten  better.  Please note - I am NOT saying that the ND filter affected the corners, but that's the only thing I changed prior to noticing better corners.  It's just an observation.

All I know is that my corners look better than they used to...

Thanks for the clarification. About the ND filter, did you had it set on AUTO or ON?

I tend to believe that corner sharpness at wide angle improves when focus point is closer to the camera... Could this be what you noticed? You may be right about the ND, but I doubt it.

You might want to have a look at my sooc jpegs from first tests I made today.  Maybe additional compares can help out. They are in my gallery.  Thanks.

I had the ND on Auto.  I tried corner sharpness at various distances.  Seeing them perk up was quite a surprise.  I'll need to set up a situation where I can test various distances.  Thanks for the heads-up.

f/7.1 had the sharpest far corners, but f/2.8 wasn't far behind. I'll be using f/2.5 to f/3.2 for the majority of my shooting, and will try to limit use of f/1.8, even though I really like narrow DOF shots.

That is a bit surprising. I thought from other reports that f/4 was the sweet spot. Different criteria perhaps? What were your criteria, and how did you prioritize them?

OK, I've done some testing, filling the frame with the back of my house. At the plane of focus, I agree that f/4 is near the sweet spot for detail sharpness at the left and right edges of the frame. Larger apertures seem to produce sharper bottom corners (ie, foreground).

24mm and 28mm edges aren't that pretty, at any aperture. Circular objects are turned oblong.

I have now set my default f-stop to f4 in-camera.

i was wondering is this a saveable setting when you say set my default f-stop?
