I'd like to go with the little guy, but before I place my bet: is this a pound for pound comparison, or outright hand to hand combat to the death?

Well, it's nearly impossible to an Apples to Apples comparo, so it will be at equal effective aperture. I have virtually no interest in keeping the little guy (f/6.3 at the long end? Please. ) so i just want to test it before selling it off.

I'll spare you the images unless you really want to see them, The bottom line is the M15-45 is quite a decent performer on the M. Nothing unacceptable really. If you can live with the slow speed (personally i don't think i can...), I'd say for the price, size and weight it's a keeper.

Thanks for posting the pics.  I agree with your previous comment in that the "M15-45 seems to be quite a decent performer on the M".  For the price of it when bought as a kit, I'll probably go for it if I buy the M5...hard to pass up for the small incremental cost.

Re: Clash with the Titan: Canon EF 24-70LII vs. M15-45IS

Personally, despite my initial prejudice, I cannot bring myself to dislike a lens that weighs as little as the EF 40mm STM pancake, and almost as little as the M22/2, yet gives you a 24-72mm (eq.) range, IS, and quite decent, if not good in most cases, IQ. One can nitpick the mount is plastic, it feels toy-ish light, and it's f/6.3 at the long end, but as a whole the little devil delivers. As Klaus at PZ said, it's not the most glorious Canon offering, but nevertheless it is quite the decent lens. Nothing to be ashamed of.

David vs Goliath might be more apt, that is David took down Goliath

Although to your other point, I might give credit to the 22 f/2 really for being David. That little guy can slay many another lens...

I covered that ground, tested that hypothesis 32 months ago, bro. Look here:

I dare you to compare Sharpness btw Canon EF 24-70LII vs. M15-45IS
2

We know the Size advantage, but what I'm really interested is :

  • 15-45 on (APS-C ) M3 @15mm F/8
  • 24-70 on (FF) Canon 6D @24mm F/8

I suspect 15-45 is SHARPER with greater DOF, and that FF is over-rated. I could be eating my words, but let see your result. It'll be FUN for all of us to ponder about.

The Apples-to-Apples comparo would have to be at equal DoF, meaning f/8 vs f13, or closer still f/6.3 vs. f/10.

Time to eat your words, Peter...

The differences are not startling or worth the extra $$$, but they are there. In summary, the Canon EF 24-70LII still looks better in the corners and in the center.

I'll say also that the 24-70LII is also just a smidge better than the M15-45 in the center.

Re: Time to eat your words, Peter...

Perhaps a better apples with apples comparison would be to use the same body with the two lenses.

How much of what we are seeing is due to the difference between and entry level mirrorless body and a pro-grade full frame body ?

Ostensibly we are testing lenses. But in reality we comparing two 24-70mm (eq) zoom systems.

Still.. I agree. To try the lenses on the same body would obviously be the best way to compare the lenses. In this case.

Thanks for taking the time though!

The problem w. the lens is that its 15mm corners never get good...
2

Here's a comparo of the Canon 16-35/4LIS on 6D, M11-22IS on M3 and M11-45IS on M, from left to right at 100% view.

extreme left-top corner: f/7.1, f/4.5, f/4.5

extreme lef-top corner: f/11, f/7.1, f/7.1

To my eyes the FF lens reigns supreme. The M11-22IS is right on its heels, though, and can be said to be, real-world, its equal. The M15-45IS lags distinctly behind.

Re: The problem w. the lens is that its 15mm corners never get good...

Sorry. I appreciate you taking the time, but I still think the test tells me close to nothing.

Like comparing a 450D with original 18-55mm kit lens to a 5D IV with 22-70 L II and saying that the 24-70 is a better lens - it undoubtedly is, but how much is from the lens and how much from the camera.

Not a true comparison IMO unless it is the same body, same lighting conditions and same camera settings with the only variable being the lens.

If, however, you were comparing a M3 kit vs 5D IV kit, then different bodies are Ok, but the comparison is somewhat redundant - a bit like comparing a BMW sports car with a Ford F350, and trying to pick a winner - you will get different opinions depending on who wants to do what with it. They are in completely different classes.

Take what you can, take what you want from these tests. No one is forcing you to take anything, or draw any conclusion.
