Boyer Apo-Saphir 10/135

[alex ph]

Here is a Boyer Apo-Saphir 10/135. I know it was used for reproduction and was praised for its sharpness. So, what intrigued me even more was its infinity capabilities. I took several shots w/o (which is still a well narrow f10) and at f12.

All shots are handheld, mounted on bellows. Auto-contrast is applied, otherwise the images are lacking a bit of colour, quite ordinary for Heliar scheme. Still the sharpness and kind of clean "naturality" are well observed even before processing.

The lens itself is small and unusually heavy. The diaphragm goes up to f45. There is a closing slot for drop-in diaphragm rings.

An interesting discussion on the forum of its larger 300mm relative was the the only well documented post I previously found about this type of lens.
