April–June 2023 Update


We have not wanted to swamp the front page with a notice for every single page we’ve added, one might easily draw the wrong conclusion that very little is going on.

Au contraire, mon amis.

Actually, for the period of April-June 2023 that impression would be more correct than usual, because, TBH, We’ve been a little more swamped with other work – both professional and private – than usual. Even so, we’ve managed to create some, significant new content, including three new walk-arounds (See full list below). Besides new pages, some older pages have received updates, especially in the form of added and improved pictures of lenses.
