I am at a crossroad in deciding what brand of 135mm f5.6 lens to purchase (contemplating between Fujinon, Nikon and Rodenstock). Would appreciate if anybody can share their personal experiences. I have a 90mm f9.0, but I find it very difficult to use hence I want to replace it with the 135mm. If this has been discussed in a previous archive, I apologise, can anybody point me to this. Thanks
