Is the EF-M 11-22 short enough to use the built-in flash?

My EF-S 10-18 with the adaptor is too long and casts a shadow when using the M6II built-in flash ... wondering if the EF-M 11-22 can let the flash light go through completely.

Thanks in advance to 11-22 owners!

On my M50, there is a shadow up to about 15mm, and none above that; just tried it in my living room shooting the couch from about 7 ft away.  Not sure if the M6II flash is any higher up on the body, but its position to the left of the lens might make the problem more pronounced...

Many thanks to your info. Right, the lower right side of my pictures with flash is shadowed because the flash is on the left side. It looks like the 11-22 is not a viable solution to my problem. One way to get around this would be to move my focus to the left and crop out the right side, LOL.

Re: Is the EF-M 11-22 short enough to use the built-in flash?

disclaimer - I haven't tested this thoroughly ...

... but through casual observations after using the built-in flash on the M50 it seems that using physically longer lenses often results in a shadow in the photo.  I'm pretty sure it's happened with me when using the 11-22, 18-55, and 18-150 but I didn't notice what focal lengths to avoid.   The 22 pancake should work without problems but using a flash attached to the hot shoe would likely be advisable when using larger (longer) lenses.

Can titling the flash upwards abit alleviate some of this?

My suggestion would be to just pick up an inexpensive TTL flash for the hotshoe.  Even the basic ones will have bounce flash capabilities, and that would solve the entire issue.

I don't have an M6 II, so these are with an M100, 12mm shorter. The first time I've used flash with that lens; it definitely needs a more powerful flash than the M100's.

22mm 1/60 f/5.6 AutoISO 640, lens hood on

All pics of a white wall only 1.1m from the camera, AV mode, full aperture, flash white balance, room lighting from 5x60W incandescent bulbs. Distortion corrected but not vignetting.

22mm 1/60 f/5.6 AutoISO 640, lens hood off

17mm 1/60 f/5 AutoISO 500, no lens hood, slight shadow of the lens visible.

11mm 1/60 f/4 AutoISO 320, no lens hood

11mm 1/60 f/4 AutoISO 800, bounced from ceiling 1.6m above.

The different white balance of the last shot is due to the faster shutter speed - the room lighting was quite bright relative to the built in flash. I also took some pictures with my smallest flash, the 90EX. Plenty of vignetting even at 22mm and various amounts of shadow at focal lengths shorter than 14mm when the lens hood was fitted. My 430EX II was fine at 11mm even with the lens hood fitted, as long as I used the diffuser, and it was powerful enough to overcome the room lighting.

But then where do I put the EVF???

Can someone invent a hotshoe splitter???

To answer both, I was trying to do a selfie in the dark, outdoors ... must need a ultra wide and nothing to bounce. Any solution for the future?

Depending on the flash used...

...you may see a darkening of the edges because the the limited angle of the flash lighting.  Most flash units (well, the ones I'm aware of) have a wider angle flash diffuser which is supposed to balance things out to wide angle specs.  However, there will still be times - depending on the scene - where the corners will be darker.

In those scenarios you can just deal with an option in most image editing programs called vignetting (I prefer the one in either LR or ACR).  With that editing option, you can bring up the edges and have them in line with the main part of the image - it's no biggie at all.

Now with a Fish Eye lens - well, that's a whole new ball game.

I believe the M6II has a flash similar to the M100. I use that exclusively by flipping it 90 degrees back with my finger. The light is more diffused and about 100x more pleasant. I believe that would solve the issue here too.
