Golden Towers
MOG Trioplan 100mm is one of those lenses that abundantly and easily produce bubbly bokeh. As almost all triplets. But even Trioplan could not produce bubbles out of thin air. Tiny points of light in the background are needed, and to make big bad bubbles they need to be far away from the subject. That is not an easy feat in the Montreal winter. Sun is scarce and there is almost nothing to be favourable background for Trioplan bokeh. A 1.1 meter MFD makes things harder.
Unless I put it on bellows or helicoid. I had excellent Topcon exacta bellows. Those screwdriver bits from camera reparation kit are a perfect source of light points and in the macro world far away from subject in background get completely different meaning.
I could get even closer but, then, the bubbly bokeh is all but lost. It becomes monotone and smooth. And, in terms of sharpness, Trioplan is far from a good macro performer.
