I actually first discovered what they were on an early shot of the train tressel. 'Looked like irregular shaped oil slicks on parts of the scan. If they don't show here, I'm glad. The old Ikonta has been really pleasing. 'Partly that I'm able to use it, partly from noticing a distinct feel to how it renders an image. The 'blad could not make this shot look like this. I strongly suspect that the old hands at LF have alot to say about the tone & feel of this or that vintage lense - like that Pinkham lens shot of the truck interior recently. That's one I won't forget soon.
