The strange thing that without a lens (without any lens) I can change the settings, but with Sigma 30mm 1.4 it's greyed out in all the menus.
It frustrates me as to why other Sigma users refuse to discuss this on the forum in any detail because it would save other folks a heck of a lot of heartache. . To Tapik: Canon don't share their camera-to-lens protocols with non-Canon companies. This is why there are occasional (regular) issues with Sigma lenses on Canon cameras. The reason why some settings are greyed-out is because Canon usually do not allow those settings with non-Canon lenses because the camera needs more lens data to work with before it can activate them. It's probably to discourage people from buying anything but Canon. From what I understand, this particular lens ought to perform just fine on the EOS M cameras. As for stabilization with video, I'm not sure - because I very rarely shoot video. But these EOS M cameras have no IBIS yet, that's only for the new EOS R6 and EOS R5 cameras. If you need video stabilization, you may need to consider a lens with OIS or consider the EOS M50 camera (which I believe has video stabilization) and the EOS M6 models... I am NOT sure about other models but this information should be easy to source. You can see two videos on this below... .
. Lens (OIS) Stabilization with f/1.4 lenses This lens doesn't have image stabilization and neither does the body of the EOS M cameras. This is not uncommon for lenses with extremely wide apertures - like this one. Canon, for example, rarely include IS with wider-angled lenses that have wide apertures. They simply don't need it. But longer lenses (eg 85mm) will indeed require some stabilization to prevent hand shake related blur. Wider lenses (eg 28mm) are less prone to the effects of shake when handheld. Lenses with f/1.2 and f/1.4 apertures rarely ever have Image Stabilization for this reason. . Sigma Lens Docks Using an optional Sigma lens dock to "tweak" the lens only affects the internal focusing elements of the lens and this is really just for DSLRs which don't use a sensor-level focusing system and suffer without an MFA (micro focus adjustment) feature. If you should sell that "adjusted" lens in future, the next person to use that lens may find it will not focus if you've altered the alignment of the lens elements via the lens dock. The EOS M cameras don't require the lens to be altered in any way and use the image projected onto the sensor to determine AF. This is DPAF (Dual Pixel Auto Focus) which is on all the modern EOS M cameras these days. Using a lens dock from Sigma has sometimes made things much worse than before. Inconsistent and out-of-focus images is the usual result of using a lens dock with some lenses when not needed. . In-Camera Lens Corrections Another thing you often can't do with non-Canon lenses is use the "in-Camera lens corrections" to correct lens distortion and to reduce vignetting. If you turn that feature on with a Sigma lens, you often get strange, circular patterns appearing on the images. You need to turn that feature off when using a Sigma lens to avoid those circular markings being imprinted on the images. The Canon lenses and EF-M native lenses don't have this issue and can use the in-Camera corrections. . Sigma + Canon camera protocols with lenses. Finally, buying a Sigma lens that works on your current model of M camera (or any other Canon camera, for that matter) may not guarantee that the same lens with work with future models of camera body. This has been the source of a lot of anger. Sigma themselves will sometimes put up warnings on their webpage and will discourage people from buying certain (*usually older) lenses for use on newer Canon bodies for this reason. Since Sigma make many of their lenses by reverse-engineering popular existing Canon lenses, they often overlook essential communications protocols that the Canon lenses have in their tiny internal microprocessors. An example of how the Canon lenses exchange information with Canon bodies was seen when the EF-M 32mm f/1.4 STM lens was released... because when you snapped that lens onto the older EOS M50 or EOS M6/M5 cameras, the camera immediately recognized the newly released lens and activated the In-Camera Lens Corrections instantly the moment the lens was attached. Canon had imprinted the in-camera lens correction data on the chip inside the lens and had programmed it to share this information (about the new lens) with the older cameras which were made long before this lens went into production. These protocols are not available for non-Canon lenses and Sigma seem to be at a loss as to why SOME (but not all) of their lenses refuse to behave on some cameras. . Offering some assistance from other Sigma lens users... Regardless of whether or not anyone agrees or disagrees with what I have said above, please offer some detailed assistance to this member. To the best of my knowledge, this lens is supposed to work well with the EOS M cameras if the EF-M version (Sigma 30mm f/1.4 DC DN Contemporary Lens for Canon EF-M) was secured. I'd assume that numerous interface options with this lens will not be available (eg lens correction) but it might help if someone with this lens (and there are a few here) could offer more details for the OP.
What i find frustrating is that you ignore sigma users who actually own the lens and just said in this very thread that digital stabilization works with sigma lenses.
So i dont know why you insist on ignoring other people's experiences and proceeding spewing canon propaganda .
Oh and fyi, in camera lens corrections work with these lenses too.
