Photoscan have lot of weak spots. Most problematic - speed, memory dependents and mask dependents (you need to create mask if you want to get clean mesh).
Yes, I tried many projects (more then 30) in RC. And its works well with some cameras and problematic with others.
I bought very expensive camera (Sony Alfa A7R2) for this work and… its disappointed me. 
I still can`t believe what so HiEnd camera makes so many problems in photgraphometry.
