I have a Shen Hao PTB45 (Chamonix 045N1 copy). It has its good sides, but I am not very happy with it. Setting it up takes a while and the lack of any locks for zero positions means that you must always check everything with a loupe even if you aren't using any movements.

Thus I thought a non folding model might be worth to look at. A Ebony 45S or SU would be great for what I do (mainly landscapes/nature), but Ebony is very expensive. I thought the Shen Hao XPO45 might be an alternative as I hardly want to go wider than 65mm.

Any XPO45 users around? Experiences? Can I expect it to work well with a 65mm and a bag bellows? How does it compare to Ebony 45S?
