Yes zooms can be quite good, even “consumer” grade! I recently got my first Limited lens, SMC 21mm, and really enjoy the lightweight, compactness of it compared to MY 18-135 and HDDA 55-300, or even my 100mm macro! I couldn’t imagine carrying anything that weighs more than 16oz, those old zooms were probably pretty heavy!
I remember when a Popular Photography came out sometime in the 70s... and three of the top 10 lenses based on some really extensive testing with many different metrics rated, and 3 of the top 10 were zooms. 1 was a Tamron, one was a Sigma, there was outrage. My memory is two Zeisses, one Pentax, two Canons, one Nikon. They tested over 100 lenses. It's not the high end zooms that have improved the most, it's what you can get in cheaper lenses. Back in 67 there were a huge number of cheap barely useable lenses, prime and zoom.
Two observations.
There have been good high quality (but expensive) zooms for a very long time. Like at least 40 years. Some people still don't understand that.
Despite that people believe even now that any Ziess or similar lens was better than its competition. I have no evidence that was ever true. Two of them were better than their competition and many other companies had 1 or two that were best in class.
The kit zooms of the 2000's are in many cases better than the primes of the 60's-2000 lenses. Look at the charts of the DA 18-135 or DA 16-85 at 24mm compared to anything but the class leading Canon 24, and they are better than their prime predecessors.
IMHO the last domain of prime photography is sub 2. My DA*60-250 is practically indistinguishable from my DA*200 at 200mm, with so much more range and less PF. But bottom line, if no money falls into my pocket before my cameras die, a K70 (or KF) would do just fine. I wouldn't bat an eyelash.
