Hey gang, question on shutter lag (without af).
...
In single frame mode, the m3 has a shutter delay even with af off!

Just tried this with my M3.  18-55mm with AF off.  No lag to speak of.
If gear matters: 6D, M3, Samyang 14/2.8, EF 24-105/4, EF 35/2.0IS, EF 50/2.5 macro, EF 85/1.8, EF 200/2.8II, EF 400/5.6, EF-M 11-22/4-5.6, EF-M 18-55/3.5-5.6, EF-M 55-200/4.5-6.3, Ext 1.4x, Lifesize conv, Ext tube EF25, 430EXII, 270EX, Yongnuo 603C

With my M3, I can only use Canon's own speedlites & triggers however, any of my off-brand TTL triggers do not work properly (ex: Yongnuo & Godox TTL Equipment).  Do you have any off-brand TTL equipment to test with the M5?  Everything worked smoothly when I had the original M and M2.

Hello JP4DESIGNZ.

Sorry for the late reply. Just hadn't much time to test my Yongnuo 622C Transceivers with the M5. But now I have done this test. Everyhting worked as it should. ETTL, M, 2nd curtain sync, HSS. I tested with M5, two Yongnuo YN 622C transceivers and the 580EXII Speedlite.

regards
Frank

Thanks for the info!  I recently switched from Yongnuo flashes to all Godox / Flashpoint flashes so hopefully the M5 will work well with them.

Is the M5 better with adapted lenses than the M3 was?   I couldn't use my 70-200 F4.   It's focusing was very very slow.

I'm yet to see any info on whether the M5 exhibits the same amount of vignetting as the M3, M2, M etc, or has managed to reduce this.  Can anyone comment or has read something somewhere?

I've only had mine for a couple of hours but I haven't noticed any vignetting issue. I haven't done specific tests, just a few sample shots. Then again it wasn't an issue for me on the M or M3.

What did jump out at me immediately is the improved dynamic range and noise performance over the M and M3. Maybe I'm just excited about a new toy but the IQ seems to be a very nice improvement over the M3.

Vignetting is an attribute of lenses only. Has noting to do with the cam/sensor behind the lens. The M5 has an aps-c sensor with the same physical dimensions as the M's before and the distance to the mount is also the same. Why should any vignetting (caused by the lenses) has gone away with the M5? That's physical not possible.

Except it is. The short flange distance of the M series means that light hitting the corners and edges of the sensor does so at a more oblique angle (away from the normal, which is the ideal), than is the case with longer-flange-diatance DSLRs. This means that less of the light makes it to the photodiodes underneath the microlenses and the colour filters.

I think I read that Leica addressed this in their own M-series rangefinder digital cameras, which also have a short flange distance, by modifying the microlenses at the edges and corners of the sensor, to increase the amount of light that gets to the photodiodes.

Without such measures, what you see is vignetting.

But one can not expect that this kind of vigentting is getting better with the M5 in respect to the M3 or M without changing this flange distance and therefor introducing yet another mount. EF-M is EF-M, same lenses same sensor sizes, same flange distances -> no change in the kind of vignetting you described. It is inherent within the M system.

don#t you think Canon might be doing this as well?  ;)  :)

Yes, they may very well be. And I hope they are. And I hope it's being done physically, to the microlenses, rather than just in software/firmware.

Not true. Canon *could* have modified the faceting of the microlenses on the M5 sensor, to reduce the vignetting effect, by increasing the amount of light reaching the photodiodes on the periphery.

Whether they *have* done so, I do not know.

There has been some speculation that this is the same sensor as the 80D, in which case the vignetting will be no better than previous M models, and I have also seen some speculation that this is a new sensor that is made especially for the M and its shorter flange distance.  Hopefully, we will know soon!
