This lens is a mixed bag for me

Good price, FL and spec.......... but corrections rob you of a good bit of resolution. Just guessing it looks like a 1.1-1.2x crop which is like 20-40% of your MPs.

As far as I can tell, applying the corrections I used is equivalent to about a 1.15 crop, which loses about 25% of your MP.

For a lens that I imagine will be used for landscapes a lot that's kind of a bummer

That would be more of a problem in the days of 8MP sensors. But even then it wouldn't have been terrible. I still have my 8MP 20D, which was an amazing camera in its day, and gave me lots of great landscape shots. This lens would have used 6 of those 8. My first DSLR was the 6MP 300D. I have several 30" X 20" poster prints of landscapes from the 300D on my walls. They look great. From a 6MP sensor. Now that we have megapixels oozing from every pore, it's even less of a problem. My R uses about 22.5 of its 30 megapixels to produce the corrected images from this lens. I can remember when everyone was waxing lyrical about the incredibly high resolution of the 1DsII, which had 17 MP. If you use an R5, you'll still be using about 33.5MP with this lens. I know that people (on these forums at least) keep insisting that they 'need' more and more megapixels. But they really don't. They're just trying to justify their lust for newer and newer gear. I prefer to not attempt to rationalize that lust. I just admit that I really like new toys (not that I can usually afford them). Need doesn't come into it. It's all about want.

But I guess that's reasonable to expect for the price/size. Kind of seems like a missed opportunity like the RF 50 1.8

Im not following your logic. If more MPs dont matter youd still be shooting a 6MP camera.

Plus I'm not even suggesting that people run out and buy super high MP bodies. But there are photography disciplines that leverage resolution. A lens that throws out 25% of the MPs it captures will be less desirable to a lens that doesnt, regardless of how many MPs are available. Having that info allows people to choose the lens that makes the most of their sensors if that is a priority.
