Full Frame RF 28-70 F2, a zoom of primes?

[JoeTheSnowPlowGuy]

Simply put, in your opinion, is the RF 28-70 F2 like a stack of primes shoved into a zoom?

For me, the versatility of the 28-70 F2 is king. It has the image quality, bokeh, and low light performance that I need without having to change between lenses. Yes, the Pink Unicorn would 24-70 F1.2, but I wonder how much that lens would cost.

The 28-70 F2 is heavy. Many folks feel that 28mm at the wide angle isn't enough. Those factors don't bother me, YMMV. Given that, for me the deciding factors came down to...

• is the additional 1+ stops of light of the primes significant enough to warrant swapping lenses?
• is the image quality of the equivalent primes better by a noticeable factor?
• is lack of IS important?
• what is the cost of the 28-70mm versus the L-series primes?

This is just my thought process. Folks don't come to the same conclusions... no right or wrong. I chose the 28-70mm F2.0 and it works best for me.
