First off, I love this lens, it sits side by side with the redcat on an AM5N, takes wonderful images, but through a Nikon Z6. The Nikon being full frame does not really utilize the higher end of the lens . Question is as this lenses Aperture is governed by the camera obviously wide open for astro. What happens if I plug in a dumb cooled ASI camera..Wheres the default, does it just stay where I left it last?....Ive been through the Sigma FAQ's and all the what do all these flashy buttons do on the side ?. and which end plugs onto the camera type stuff
.. But nothing comes to light. anyone out there that can shed some aperture on this ???
Cheers
