ZM 21/4,5 Biogon and the 25mm hood
Can anybody confirm that this hood does not vignette on the 21 Biogon ? I've seen in Tom Abrahamsson's review that he wanted to give it a try, but there was no confirmation as to the result. My Biogon has arrived this morning, and I will be off in the afternoon for a short trip, so I have no time for testing this myself. Any experience will be appreciated. Thanks.
