Joules...I've been here a long time....please don't troll. You may not know much about lens construction....but some of us have been shooting professionally for a very long time. My first Professional Canon camera body was Pre AF....in fact I still have it. I also have an original ef 50mm f1.8 from the first year of EOS.Seriously? The EF version doesn't have IS!
Any reference for that? It seems hard to believe. Relative to what? Component wise? What does that mean?
If developing lenses were such an easy and inexpensive task, why would it take so many years for any mirrorless system to flesh out it's lens offerings? And why would the manufacturers not lower prices to compete with smartphones better?
Go look up some of my photos....many are to be found on these forum pages.
