Just can't believe anyone would ditch an A7 for DSLR over dust bunnies...
get a DSLR mirror mechanism spraying oil and bits of its mechanism over the sensor and you're back to square one.
No offence meant rookies and not talking about just you specifcally but we see people on this forum time and time again bouncing from camera to camera and initially they're very positive and trash the last thing they had all over the net and then it all goes wrong in a big way... and they're off on one again and they're never happy.
It's a hobby I suppose
