Fantastic contre-jour! Seems the IQ of that 17mm is just fine, would you agree in prints?
Thanks Fixcinator, good timing more than anything, and that due to luck - realised I was missing some ingredients for dinner on Wednesday and grabbed my camera for the walk. It had only recently stopped raining as if the setting sun wasn't enough.
I've yet to print larger than A4, but I've certainly been happy with those. Aside from the great IQ, it's also a really easy to use lens too as the focus throw is only about 80 degrees, and anything over about 1.2m away and you may as well be at infinity.
Ok, so I did some experimenting and all you need to do is short out ONE (any one) of the pins on the lower left. I use one of the end pins for ease. This will prevent aperture information from being transmitted and will enable trap-AF. This will turn all F + lenses into M or K lenses - you need to input FL, so it is unfortunate for zooms.
I have a tiny square piece of foil with a slightly larger clear tape around it that I attach to the lens body and it stays when attaching my F 50/1.7 and obviously M42 lenses. For me this is better than holding the lens release for trap-AF (which will make it keep spinning). I tape this to my M42 adapter when I'm not using it.
but the lens release is awesome for quick shift focusing on non QS lenses (no need to switch AF/MF back and forth, just push button , MF, and release) and doesn't seem to harm the AF screw (you can move it when you let go to hear it click back into place. When you place a lens on it won't be completely lined up anyway.)
Only one pin needs to be shorted for trap-AF, not all of them (like I have seen pictures of)
