Are you fed up with the ever increasing cost of Canon gear?

If you can't afford Canon gear, then take a hard look at Sony.

Sony has a more "mature" mirrorless platform with lots of third-party option.   It's those non-Sony options that make Sony more budget friendly.  If you buy GM lenses new (Sony's top-of-the-line offerings), they're just as expensive as Canon's L lenses.  Sony is about to release its second generation GM zooms, and I wouldn't be surprised if their prices exceeded equivalent Canon R offerings.

However, Sony mirrorless has Tamron, Sigma, and other offerings that are much more affordable.

Nevertheless, I've moved back to Canon and have no regrets.  In fact, I took a hard look at the A1 because it outperforms my R5 in many respects.   However, I've found the R5 much more comfortable to use--not just the ergonomics but the functioning--after a couple a months than in four years of Sony use. In fact, my R5 is far more enjoyable to use than my 5D MIII--the last Canon DSLR I owned. Therefore, while tempted to purchase the A1, I decided joy of use is more important than specs.

Thus, I'm willing to pay the premium to use Canon. Fairness is such an arbitrary term in economic markets. Unless the product is a necessity--potable water, fuel, or wood during a hurricane--fairness has no place in determining prices.   For discretionary items--and mirrorless cameras are absolutely discretionary--market-clearing prices will be determined endogenously.  If the prices are too high, then Canon and resellers will be saddled with excess inventory, and gray market sources will provide alternative lower-priced options.  Currently, there appears to be excess demand rather than excess inventory, so I can't criticize Canon for pricing products too dear. I don't like the prices, but I'm happy that I can afford to pay for what I want.
