“Even before mirrorless they were dabbling in new camera tech. Remember SLT? The a55/65 etc were popular for a minute. I got my start in photography on the Sony a55 in 2012 and it was like looking into the future without really knowing it.”

“sony a55 77 slt, but why bother dead systems. You might aswell move now to mirrorless, for 500-600 you would be in range of a6000 series with maybe a lens or 2 extra batteries and a bag.”
