You know when I said that the poor results I was getting seemed to be down to infinity focus not being spot on?
I was using a cheap Chinese-made M42-Adaptall adapter at the time so last night I took my genuine Tamron-made M42-Adaptall adapter off my 300mm/f2.8 and fitted it to the 17mm/3.5...Its now works ok!
Seems the cheap one is slightly thicker, not allowing the rear element to come back far enough for spot on infinity.
I\'m looking for an adapter right now. The original ones are pretty rare & expensive. Can anyone recommend a Chinese-Taiwanese one that is known to be good?
