Will confirm whether it is worthwhile since it was a birthday present many moons ago from my good wife. Does it work well as extensive tubes? I am sure she will not know the difference if I put it to good other use. I must say that the DA* is so good that I hoped it will make up for loss of IQ
Thanks again for both your replies and the posting of the picture SOldBear
All credit to SOldBear for assisting me with this sometime ago, I couldn't remember which thread this subject was under - better to simply describe the process. Deglassed TC as an extension tube works great for macro retaining the AE function with your PK/A macro lenses, best TC I found is the Pentax F 1.7x AFA but it's expensive.
