I own the TZ45BII. Its specifications are similar to the HXZ but it is lighter. I mainily do landscape and have found it more than adequate for my needs. Indeed I have never ran out of bellows draw. My widest lens is a 90mm although I have never used it yet, finding my 120 and 180 best suited to the photographs I have taken with it so far. I own a bag bellows and anticipate only using it with the 90 just to make using movements that much easier. My camera was upgraded with an ebony screen which was a direct replacement and is brighter than the original Shen Hao screen. This is also my first brand new camera and I anticiapate using it for the foreseeable future. I have a Linhof Cardan GT but it is so heavy that I would only use it where the subject was near a car park.
