Lens Shades and Series VII Filters

Did you know that both the 12504 and 12501 lens shades for the 35 Summilux Canada and the 21 Super-Angulon f3,4 (respectively) can take Series VII filters in the shade itself? The Super-Angulon f3,4M lens can also accept e48 thread-in filters, but if you have old Series VII filters kicking around, put them to good use!

Close and Closer

The newly announced 35mm APO M lens from Leica is a technological wonder. It close-focuses to 0.3M. But don’t forget, the 35mm SL lens close-focuses to 10 inches (on the SL, SL2 and SL2-S of course).

This means you can use the series VII filters with two current lenses in a wide angle kit. The Summilux-M 21mm f/1.4 ASPH uses the series VIII filter which is larger and does not fit these lens hoods.
