In the meantime, I am kicking myself. Two years in the past I had an opportunity to buy a 24-70 F/4 for $550, and I believed… meh, that is kinda dear. Now it is going for $1200 on ebay from respected locations. The 16-35 F/4 can also be skyrocketing. Perhaps provide disruptions are part of this, however there’s nonetheless a lot demand in good EF lenses, and so they’re optically no worse than the RF variations. Is Canon leaving cash on the desk?
