Thanks, Jim! Yes, I do but more in the same fashion of semi close-up though. It is a new lens and I haven't had the chance to use it that much. In addition, I also bought a Sony A7r and used that lens on that new 36MP camera and posted images taken with the Sonnar using extension tube(s) and that camera here (scroll down a little, please): https://www.fredmiranda.com/forum/topic/1255248/58. It is a great lens, even for close ups.
I thought that 100/2 Makro Planar and 135/2 Sonnar are too close fls to each other to justify 135/2 purchase,but looking at your flowers I feel like the distance between 100mm and 135mm rapidly started to extend.Just sheer physics,you know.
