This is my last still life to date w/the Semi-Achromatic.  It's a long tall slender glass flower vase lying on its side on brushed aluminum.  I didn't set out for it to look like this but after setting up the shot, I looked through the groundglass and this is what I saw.  This was shot w/the SA wideopen @4.5. 

I called this shot 'Chemical Focus' because I focus on the rim of the glass closest to the camera, but more was in focus that what I saw on the groundglass. 

I gotta comment on what Steve Nichols said on one of the forums, I like what you said, and will say it here.  You inspired me to go out and get a Raptor w/your Raptor shot of the foundry.   I think these lenses do have a distinctive quality that can be exploited and expressed and they do have a definable 'personality'  when everything works right but it doesn't work out that way with  every single shot.  I think that's what some folks are missing, you can't just slap on the lens and have the lens put its personality stamp on whatever you're shooting just because you used that lens, you gotta make it work.

Same w/the Semi-Achromatic, I've shot quite a bit, including tests, you'd be surprised how much I've shot, but the shots I'm happy with from this lens you can count with the fingers on one hand.

Take care
