so - I've been lucky again... (I think) I got an Hermagis 540mm for a bargain price. I have fitted it on my huge 40x50cm (16x20") mahogany camera, and it seems that the image circle is good for this size. Th lens it self isn't that big or heavy, and it isn't mentioned in the Vademecum of lenses (nothing on that long foci):confused: So the question is: do any of you (Ole?) know about this lens? I've attached some images here.. it says (hard to read) "Apla." nr 3 serie II and 540cm serial nr 27.111 not that it is that important... I'm going to have fun using it - and the image on the screen looks right! swirley bagkground - but not too much.
