Yeh, I have tried most of that. FP seems like a gimmick to me, I get better sharpness without it. SR is always off when mounted on a tripod (in fact I often have SR off when hand held, my *istDS days taught me how to hold steady)
As mentioned, I'm not going to spend more money on play things right now, certainly not another tripod if you consider the Velbon too light..
Lenses I've tried
18-250mm DA
18-55mm DA
30mm Sigma Prime
84mm Sigma Zoom II manual lens (best results of the lot, but still rubbish)
That's all the lenses I have aside from the 55-300mm DAL ED on the K-7 which is pointless trying.
I'm not going to be buying any more lenses, this is a hobby only and my funds are limited.
The paint is still yet to dry in the adapter interior. I'll try again once I get a good matt coating..
If that doesn't help, I'll definitely bin it. I only bought it out of curiosity
