Leon that is a great lens. Should give you a FOV of 4.12 x 2.75 degrees with the Canon 5D.
Wide open is the aperture 125mm? Be good to do a comparison to your TAK. what size is the rear filter holder? The earlier ones were 48mm but you can also get a 52mm drop in filter holder.
I have a drop in Canon rotatable polarizing filter that is great for terrestial use. You are welcome to borrow it for an extended period as I never use it as my lens is stuck on the mount.
