In single frame mode, the m3 has a shutter delay even with af off!

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.Photorex said:d said: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.

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.

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.
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.AvTvM said:Fleetie said:...

don#t you think Canon might be doing this as well?
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.Photorex said:Fleetie said:Except it is.

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.
