Help with orthophoto quality. How to improve it?

I made some UAV datasets with a Canon SX260. But I'm not liking the final orthophoto results, it looks blurred in comparison to the original picture. I have a good overlap and good picture quality control. The total dataset is more than 700 pictures.
Original Picture (I picked a house with a pool)
Agisoft Ortho (Small area CROP at 100% )
The original picture:

FULL SIZE PICTURES:
The original size Agisoft Result:

You can see that the difference between the original picture and what agisoft produced as an orthophoto is big. Why?
I alligned in high, optmized, dense cloud was high and mesh was high. Didn't changed much besides that.
What can I do in the workflow to improve the quality of the ortho?

Do you have some bad images --> estimate image Quality...

Hello Fernandoker,
It will be also interesting to see the Chunk Info screenshot and solid view for the given area.

I removed many low quality images, based on agisoft info.
Chunk Info and Export info.

Looks like there are som "bad" images... becose in some regions the orthophoto is sharp.
what is the lowest image quality?

You could select a few points of the sparse cloud in that area, then right click and filter photos by points. Then you only have a handful of images to check through and you can be fairly sure you've seen them all.
