Mine is supposed to be delivered tomorrow - I understood that the A7r, due to the lack of the electronic 1st curtain, is relatively vulnerable to camera/lens combo movement on long exposures. Has any of you guys tried this out with your largish Canon lens(es) on sturdy support? Any result worthwhile mentioning? Thanks!

It is a 36MP camera, which is more susceptible to shake and Sony (deliberately or not) omitted this feature while the 24MP A7 has this feature. What\'s up with that?


I tried the ts17 and ts24 which are largish lens and did not find blur. I compared the 5diii/ts17 and ar7/ts17 on large gitzo, acratech ball head and pixel peeped. I found more resolution in a7r image than the 5diii, which suggests it is not a big issue. I tried it at 1/320s.

However, it is loud and that suggests a vibration and dampening. it is the dumbest thing to do for a high resolution slow focus camera. Sony has their head up their xxxxx in this design. It could have been avoided.
