I am pondering whether to get a Shen Hao TZ45 IIB and am interested in the user experience in terms of sturdiness and reliability. I have been hauling around a Sinar A1 for the past 20 years. Its a wonderful camera with lots of movements, ease of use and reliability. But I am seeking a lighter load, as well as avoiding packing a rail camera. Its been a while since I have seen a thread on the TZ45IIB and I am wondering how it is faring among those of you using it. I use lenses from 90 MM to 300mm. Assume none of these are an issue with the TZ45 IIB. Thanks. JAMeyers55.
