With over 45 years of experience in photography, when it came time to buy a new camera I took my time and eventually purchased this camera for two reasons.
First 4K video and second low light performance. On the first I have yet to record any 4K events. Yes, it is a little disappointing that this camera cannot record 4K when others on the market, including the new a7RII have this attribute. Yet I understand why Sony elected not to at the time, they were aiming at the video professional market.
But for the second reason this camera is amazing. It actually opened another door for me into astrophotography, not only open sky but telescope imaging as well. With this camera I can clearly see the stars my eyes cannot see and most important focus on them very very accurately.
Now I know Sony reads feedback and I hope that Sony will release astrophotography apps. Maybe extending the shutter time well beyond 30 seconds (I understand there maybe some thermal issues, but the app should be able to take that into account), enhanced long exposure noise reduction designed for astrophotography. Who knows maybe someday soon even release a limited edition a7s designed for astrophotography like the D810a.
Bottom line: If I had to do it all over again I would still buy the a7s and that says it all. Should Sony come out with a astrophotography version I would buy that as well.
