I use this projection lens deliberately way out of spec for close-ups....
 
Yet another fine set, Klaus!

Just out of curiosity, do you know what the effective aperture was for the 154mm? Whatever it was, it was effective here.

Thanks Tom! That might have been around f2.8 I guess that close, the nominal f-stop is f1.9 and quite fast for a lens with 154mm focal length
