With all the new features on the new Canon cameras I am thinking they are getting a lot of calls.

They should just point everybody to these forums.    They’ll get invaluable help here!

well, time is money for sure

but I couldn't figure out the focus sensitivity adjustments provided on my 7d mark II

Canon is moving to put the camera in AI and let the camera decide to focus -- let it rip

Yup.  These technologies are just in their infancy (A.I. is exploding), and Canon is surely positioning themselves to succeed.

Any company that’s figuring on technology plateauing is absolutely going to get run over.

Canon does not have enough workers to answer calls about why a Sigma or Viltrox lens will not get all of the kids eyes in focus ?

Stuff like why are Joey's eyes always in focus but Jimmy's are not with my new Viltrox lens on my R50 ?

Canon, in part, doesn't want all the calls for third party issues that take away valuable time

Bingo.  More time to devote to R&D for their own lenses (and bodies).  More sales and profits from their own lenses that would have gone to 3rd party!  A stronger company position means better products for you and I.

I love Canon’s stuff.  I see this exclusivity as a good thing in the overall picture.

there are so many firmware updates going on by Canon with RF that they would continually hose third party

That right there has to be the big fear for 3rd party.  Imagine all of the resources being poured into a product line, and in an instant * POOF * none of it works.  Then even if you can develop a fix, the damage has been done.

Nightmare scenario folks.

Re: Problem with Sigma 18-50/2.8 and X-T5: Fujifilm X System / SLR Talk Forum: Digital Photography Review (dpreview.com)

There is currently a bug in the Sigma firmware that causes a one stop under exposure to occur, but only when zoomed out to 50mm. Calling that a "nightmare" is wild hyperbole. I am sure DXO should be able to handle increasing the exposure by one stop to compensate.

Given how many people in this forum have been clamoring for this lens in EF-M mount, many would likely still happily purchase this lens, even with the small firmware bug. It is no longer 1985. Sigma has a strong track record of fixing their firmware bugs, and this lens will be no different.

Or wait... maybe the bug is a good thing. Given how many times you have claimed that the existence of the Sigma lenes in Fuji mount would obliterate sales of original Fuji lenses, maybe this bug just saved Fuji from bankruptcy.

Too funny ... maybe it will save them Yeah, right,,,

btw - I hear a lot of complaints that folks are not too happy with the last two X-T updates so I think you'll not be updating to 4 or 5 from your version 3 - there in lies another issue of business continuity - they can't get you and others to upgrade

You are the one who was outspoken for the ending of m... I guess they listened to you

nope, no more investment for me in m - R8 and RF F4L is my path

you think this siggy exposure fix will be easy - just look at how many over there are returning their sigma lenses

with Canon doing many firmware adjustments to lenses and bodies in the RF world, it is no wonder they don't want to be bothered with trying to explain to customers like you would, no worries, it is just a small issue that will be corrected soon by sigma - yeah right, some of the posts show sigma is in denial...

that is not a small issue

and Canon updates firmware all the time, third party can't keep up, and Canon can't be bothered or they would lose

T4 was not an upgrade for T3 any more then M6 was an upgrade for M5. Different models targeting different users. The T5 is the true replacement for the T3. The X-H series is the replacement for the T4.

As for getting people to upgrade, how many here are complaining that RF-S is not an upgrade for EF-M? I keep seeing people that were active in this forum pop up in the Fuji forum as new Fuji owners

thanks for explaining that T3 is only one generation from T5, I was confused by naming structure

I'm moving to more reliance on subject tracking with the R8 where fuji lags behind

Canon is getting me to buy an R8 just 3.5 years after I bought an RP

but I see in Fuji's case they haven't provided you with something you want to upgrade to since your X-T3

You are the one who was outspoken for the ending of m... I guess they listened to you

No, I just recognized Canon's strategy much earlier than some others here. Updating the M6 and not the more popular M5 was a big clue.

touché

nope, no more investment for me in m - R8 and RF F4L is my path

Which is incredibly ironic given how many times you denigrated 24mp and repeatedly claimed you would never buy another camera with less than 32mp

I'd still not buy 24 mpxl crop. In fact, I think m6II is my last crop.   But the clear as a bell Canon 24.2 mpxl FF sensor sold me...

The R8 can AF at EV -6.5 – 21 (at 23°C & ISO100). EV -6.5 is crazy dark.

The R8's 24.2 MP imaging sensor out resolves the RP's higher 26.2 MP results

The R8's 24.2 MP imaging sensor out resolves the R's higher 30.4 MP results

@ 20 fps craw in e-shutter with a tad better read speed than R5, looks like R8 gets a couple hundred shots in just over 10 second bursts with R3 - like subject tracking without ruining the shutter and with economical long lenses.

you think this siggy exposure fix will be easy - just look at how many over there are returning their sigma lenses

It is not the first time a new Sigma lens had weird exposure issues, but they always get fixed.

we shall see how long it takes

with Canon doing many firmware adjustments to lenses and bodies in the RF world, it is no wonder they don't want to be bothered with trying to explain to customers like you would, no worries, it is just a small issue that will be corrected soon by sigma - yeah right, some of the posts show sigma is in denial...

Denial? Like Canon's public comments on the future of the M system?

it is what it is

that is not a small issue

and Canon updates firmware all the time, third party can't keep up, and Canon can't be bothered or they would lose

Frequently updating communication protocols is not a problem if you are openly sharing those protocols. It only becomes a problem if you try to keep those protocols a secret and third party manufacturers need to rely on reverse engineering.

The sole third party AF lens for RF mount that started the threats of legal action wasn't even using the new RF protocols. It was basically an EF lens running EF protocols with a permanently attached mount adapter. It was using protocols that Canon is no longer updating.

interesting

we shall see how it plays out

I read somewhere that with the RF mount, Canon has transitioned to more of a digital, computer world where many more firmware updates will be necessary to both bodies and glass because of the complexity of these beasts.  Canon has made it easy to uspdate both in their bodies.

Also Canon seems to be using the Sony strategy to flood the market with model after model and update after update so rushing to market often leads to more updates.

I do not expect them to share their protocol, but to answer the market at every turn

It appears they are providing me with something I want to buy (ie, R8 just 3.5 years after I got my RP), and that is the key for me, and for them

Ouch !

Camera firmware programs are now so large they will always have bugs ?

Like all large computer programs ?

Here is a recent email conversation I had with a Sigma rep on February 14th.

Me: "Hello. I see a lot of Sigma lenses available in the Sony E mount that I would love to see available in a Canon EF-M mount. Can I look forward to a more robust offering of Sigma lenses for the Canon EF-M mount in the future? Thank you."

Sigma rep: "Thank you for contacting us and having interest in our products. sadly cannon is moving away from the M-mount. They are putting all their eggs in one basket with the one RF mount system. my guess is that our releases for that particular amount will be very limited based on what Canon is doing with that camera system.

Me: "Thanks for the quick reply. Yes, I am definitely aware that Canon has neglected its customers by discontinuing the EOS-M line. This, however, does not seem to stop other third-party brands from continuing to release new EF-M mount lenses.

There is still an extremely large and loyal number of EOS-M owners all over the world. It is unfortunate that we cannot benefit from the impressive line of Sigma lenses that seem easily capable of being offered with a Canon EF-M mount. I do sincerely hope that Sigma might reconsider its plan for future EF-M mount lenses. They would not go unappreciated."

Sigma rep: "Historically we've been down this road before with other brands and other products. with times the way they are we cannot afford to be saddled with inventory that we can't sell. my suggestion would be to either find some form of an adapter that goes from the E mount to the M mount or contact one of those companies like fotodiox we're metabones and put the bug in their ear about it."

Sigma is not going to make any new EF-M lenses.
