Originally posted by biz-engineer Longevity isn't a problem on MILC cameras because all models of 2018 will be obsolete by 2021. Sony understood that rapidely with their Sony A7 series, they moved to China for the manufacturing, since reliability isn't relevant when camera products are made obsolete every other year (even a $3500 camera). The trend with cameras is increasing prices of already expensive devices of consumer grade quality.
That's odd, because my a7III is made in Thailand (brand new, made sometime after May as it came with the latest FW). Not that it makes a difference, go where labor is cheaper. Pentax makes their stuff in the Philippines, and as long as the tooling is up to date, eh, and camera failures or lens variation never occur in Pentaxland. In spite of the all the QA/QC, failures happen.
Sony may assemble in different countries, but that would make sense, as I remember when the flooding in Thailand about a decade ago raised hard drive prices, as it was basically a primary location were they were made. Now, I think the manufacture is more varied.
I am curious what the sources are on MILC failure rates vs dSLRs. I'm also guessing they do NVH testing.
