There has not been many posts about this p67 lens on photo.net so far. Nor can I find it in elsewhere either. Since I have this lens I thought to share my recent experience about it here. Frankly I am a little frustrated in using it. I have not been able to capture any images (mainly people shots) with main object sharp in focus and soft everything else. The degree of softness of the out of focus area can be controlled by the aperature opening. The wider the aperature the softer it will be. The problem is the in focus object (face of people as an example) is getting too soft and appears like out of focus when I want all out of focus area to be softer by widening the aperature. At f5.6 the softness effect looks really good but the main object looks like out of fucs too. At f8 the lens is losing the softness and yet the main object is not sharp enough. By f11 the softness is mostly gone then the main object looks in focus too. Is it because I did not use it correctly or what? Between f5.6 and f8 the softness of out of focus background looks really nice. You won't see that kind of softness from regular lenses. The problem is the in focus main object is never sharp enough. This is especially the case when shooting pictures of people with head to toe all included in the frame. The background is soft and good but the people looks out of focus. I don't know about head shots. I seldom shoot head shots. The focal length of this lens is too short for head shots. I did have good results in using it as a closeup lens. It focuses really close. And it focuses beyond infinity (meaning you can turn the focus ring passing the focus point of infinity). When closing down the aperature the background will be still very soft and the softness (maybe it should be referred to as bokeh) is still plenty soft. At f11 the image in the prism of my 67II is still plenty bright. Shooting flowers as an example the bokeh is something not seen from regular closeup lenses. I had a shot of flower that has a building in the background. The building is so soft that you basically will not notice it but its shape is still intact as a building. The lens has a minimal aperature of f22. It would be fantastic if it gets to f32 or f64.
