Sigma confirms: no support for Canon mirrorless

I purchased a Canon M5 and a Canon M3 for Christmas, and have been trying them out.

The M3 was a gift for my daughter, as a travel-friendly alternative to her 6D. She also got the 22mm f/2 M-series lens and a generic (Meike) mount adapter. My wife received the M5 body as an upgrade to the EOS 400D (inherited from our daughter some years ago). The M5 was the body-only "starter pack" that comes with the Canon EF/EF-S to EF-M mount adapter (without the tripod extension, frustratingly).

This offered a good range of options to test the lenses we had on hand. We quickly found a problem with the Sigma 18-250mm f/3.5-6.3 DC MACRO OS HSM. This is a handy 'travel' lens and thus seemed ideally suited to the mirrorless body, even with the added bulk of the adapter.

In brief, the Sigma 18-250mm works on both bodies, but there are problems when powering off. Neither body switches off fully for one minute. It seems that the lens is holding onto the sensor for a full 60 seconds after the switch is turned off. There is a distinct click after 60 seconds - perhaps releasing the sensor (just guessing). The M3 screen goes blank but is not off. Opening the battery cover will turn it off completely. The M5 seems to power down but cannot be turned on again immediately. Removing the battery will re-set things.

I tried this with various combinations of lenses, adapters, SD cards and batteries (I also purchased a couple of generic cells that work well, though neither the M3 nor the M5 will display the remaining charge, as expected). I also tested an older Sigma 17-70 f/2.8-4.5, which does not seem to have any issues.

I wrote to Sigma in Switzerland, where I am based, and they contacted Sigma Japan. Their response: "A Happy New Year. As you may know our lenses are optimized to DSLR cameras. So there may be incompatibility issue when it attached to Canon M series cameras. In other words, our products to not support Canon mirror less cameras." (my emphasis). Canon's Swiss rep. added, "We are sorry we could not give you any better news."

Perhaps I was naive to expect anything different. However it does seem short-sighted from Sigma. They promote the 18-250mm as a travel-friendly compact zoom, and I would not be alone in expecting it to be a useful pairing with the smaller mirrorless bodies. Buyers be warned.

This is my wife's favourite lens, as she likes to shoot birds as well as bugs and flowers. It is disappointing that it is no longer reliable. The M5 is a nice upgrade to the 400D of course, and it is too late to return my purchase to Canon (which is not at fault).

In the hunt for the ideal super zoom, I will take a closer look at the Canon EF-M 55-200mm f/4.5-6.3 IS STM, though it lacks the range and macro facility of the Sigma. I had considered the Tamron 18-270mm F/3,5-6,3 Di II VC PZD, when buying the Sigma three years ago. I would welcome suggestions on good alternatives!

Not sure where you purchased the camera, but are you sure you have the latest version of the mount adaptor?  It sounds a little suspicious that it does not have the tripod extension.

The 'Starter Pack' available in some territories includes a 'free' EF adaptor, but doesn't include the tripod foot.

Discussed extensively in the past when people got their deliveries. e.g. https://www.dpreview.com/forums/post/58705105

it seems that the EF-m to EF mount adapter supplied with the M5 in the europe market comes without the tripod mount

I'd reserve "very sharp" to non ef-s and non 5x+ lenses. L lenses and good primes are very sharp. Usually is those that don't have better lenses that say the low end zooms are very good!

do you count the 70-200F4L sharp?? 70-200 f4L vs 55-250 stm

That's a non 5x+

do you count the £2500 GBP 11-24 f4L sharp EF-M 11-22mm vs 11-24 F4L

So is that.

So we need to know whether Red Fox 88 meant that both conditions cited were individually necessary for a lens being "very sharp". As stated,  his post suggests that a lens has to be non EF-S to be very sharp, and it has to be non 5X+. Therefore a single very sharp EF-S lens, no matter the zoom range, would count as a counterexample. But perhaps he meant that lenses have to be non (EF-S and 5X+) to have a chance at being very sharp. In which case, what he said is consistent with an EF-S lens being very sharp, so long as it isn't also a 5X+ zoom. It's a matter of the scope of the negation (in technical logical terms).

And yes, I know this is very pedantic. It's actually my job to be pedantic (I'm a professor), and logic is one of the subjects I'm qualified to teach. At least I've given you something different to be annoyed at.

do you count the 17-40 F4L sharp EF-s 17-55 F2.8 vs 17-40 F4L

And that.

do you count the 24mm F1.4L sharp

From the above, yes.

The EF-m 22 f2 is at a big disadvantage as the L glass is on FF+ more MP but the 22/2 still puts up a good show EF-M 22mm F2 vs 24mm F1.4L

Pretty sure that counts as a good prime?

+1 to Crash's suggestion (unless she wants to go as small as possible). Great lens, though she'll need to pair it with another for the wider stuff.

Yes, that is correct. Here in the UK, the special "Starter Pack" for the EOS M5 is boxed (by Canon) with a normal EOS M5 kit (with original box) within a special Starter Kit outer box, and that box has a flap inside to retain a starter-kit boxed EF to EF-M adapter. The box itself is flimsier than the usual package, but the item itself is absolutely identical (and is genuine, authentic etc.) - except that the tripod adapter, which is normally supplied attached to the adapter, though it can of course be removed, is intentionally absent. The small print on the packaging points this out. The adapter retains the necessary sockets for attaching one (if you already have it!).

When I bought my adapter, the first thing I did was remove the tripod foot. I've never needed it, and I'm not sure I could lay my hands on it, if I wanted to. If a lens is big enough to require a tripod mount, I would use the mount on the lens. If it isn't, I would mount the camera directly on the tripod. I really can't think of any lens that I could mount on my M, where I would want to use the tripod foot on the mount adapter, rather than on the lens itself (if big enough), or just use the tripod socket on the camera. But perhaps there are one of two lenses that fit that description.

ROFLMAO

Oh come on now, no one cares about logic, it doesn't matter if the lens is sharp or not, nor if the Sigma lenses work or not, it's all about the mind behind the camera. A skilled and creative photographer will make any lens work. Heck, you don't even need a lens, just a small hole in a body cap. Turn your old Bigma into a super sized lens cup for those long road trips, the vacation location is more important than the gear.

We don't care about these logical technicalities. Am I too early in the post count for this? ;P

The same behavier with my M5 and the Sigma 17-50 and 17-70 Contemporary. My workaround: Just don't switch the camera off. My setup is a short time to switch off the display, not the camera. Only when making a pause (more than 5 minutes) the M5 is switched off.

This is not ideal, but it works. Both of the Sigmas are my best lenses (far better than EF-M 1545 and EF-M 1855), so I think it is worth the "workaround". If I need the cam "immediately" after switching off (within the 60-90 seconds the software needs to "refresh" the cam), I rotate the lense within it's bajonett (without removing it) - the camera does a reset and starts within a second - that's it.

At the moment I don't know any mirrorless cam (MFT/APS-C), which could compete with my M5/Sigma 1750 pairing, no Olympus, no Sony, no Pana and no Fuji, I have tried all of them - so I'm very happy with this. The only cam where I prefer the picture quality is the Canon 6D - but the combination of IQ, size and weight gives the M5 a premium position.

I can confirm the same with the EOS M6, but with the original M i have no problem...so it works at least with one mirrorless...

That's a non 5x+

but its a non EF-s so shuld not be classed as  very sharp

do you count the £2500 GBP 11-24 f4L sharp EF-M 11-22mm vs 11-24 F4L

So is that.

but its a cheap lens like non FE-s

do you count the 17-40 F4L sharp EF-s 17-55 F2.8 vs 17-40 F4L

And that.

its non EF-s

do you count the 24mm F1.4L sharp

From the above, yes.

The EF-m 22 f2 is at a big disadvantage as the L glass is on FF+ more MP but the 22/2 still puts up a good show EF-M 22mm F2 vs 24mm F1.4L

Pretty sure that counts as a good prime?

let you have that 1...

i miss your reply better lat than never
