Re: Best DSLR or ILC for Night Sky Imaging?

I want to thank everyone who responded to my initial post.  I've learned a few things (well, maybe more than a few) that I didn't know before.  I posted this query because I really didn't know whether my Canon 5Div was an optimum performer when it came to minimal noise at higher ISOs.

The information about the Sony A7s was news to me and very interesting.  In principal, I can afford to buy an A7s (plus a Metabones adapter so my EF mount lenses will work on the A7s).  However, while my budget may be capable of absorbing that expense, my 40 years of managing other peoples' money still governs my instincts.  That's not to say "economy at any cost," but rather "evaluate whether the additional cost is justified by the performance gains."

That led me to check DPR's review of the A7s and compare noise levels at ISO 6400 for both the A7s and the 5Div.  I'll concede the A7s has the edge, but it seems to me that it's an almost imperceptible edge over the 5Div.  However, the 5Div's edge is, based on Rogers comments, its 5.35 micron pixel size despite being a FF sensor.

On that basis, it seems to me there is really no point in acquiring the Sony A7s no matter how affordable it might be.  Does anyone disagree with that assessment?  If so, please explain.
