I have a P645 150mm, roughly equivalent to 100mm on full frame on the Vertex.
Not sure where I could find a subject that matches your criteria.
I have this, the bottom edge might be useful. Download and process to taste:

Wow! That looks great! That lens seems to produce really good, fine detail. The details on the tip of that spire sure look good. I think the bottom edge might be a little out of focus, though it still looks pretty good. It's pretty close to the center, like the spire point, but the flaking white paint on the steeple sure looks full of fine detail. Do you have any idea how far you stopped down, when you shot that photo?
P.S. Is this the lens you have/had?

After looking through these, I feel like getting this one for landscapes:

I just wish the aperture had more than 8 blades. It only weighs 470 grams! I currently don't have a lens in 35mm focal length for my Nikon D810, and for landscapes I would use manual focus for critical focusing most of the time anyway.
