Originally posted by Orbus Thanks for the encouraging comment, Eric. Yes, I was pleasantly surprised at what could be achieved with this lens/extension tube combo. I purchased a set of original Asahi/Pentax M42 rings last year but never really had an opportunity to give them a proper workout until now when your recent posts intrigued and challenged me. As I mentioned previously, it was a struggle to achieve accurate focus with a lot of the shots. Couple that with the fact that my dedicated M42 camera is an old K-m which gets better results at lower sensitivities (<400) so I was dealing with relatively slow shutter speeds. I did find using a monopod helped; not only to steady my hands but to be able to pivot the camera back and forth on the leg to fine tune the focus. I will definitely spend some more time playing around with these rings in the future and try them on a few of my other longer-focal-length Taks like the 135 & 200. Great fun!
Here are a couple more from the 150mm and #3 ring combo:
Wow, you are doing great! Yes, focus is tricky even with the K-1, but it does help me with the big viewfinder and CIF (leave AF turned On, then set min focus distance you want, then lean in... sloooowly, heh.)
None of these are flash, though I do have a soft bonnet for my AF360 for fill flash I use at times for macro with my DFA100WR, but prefer natural light if I can get away with it. All handheld.
