I'm getting a bit bored of this rhetoric now.

Look at Sony. When they launched FE, their in house lenses were absolute bobbins - the majority of which were simply DSLR designs shoehorned into mirrorless (some of which are still "current" designs now.

Without 3rd party support, FE mount would have been a car crash.

Putting the massive RF teles to one side, Canon has given us some brilliant "from the ground up" RF lenses. All alongside having full native support for that massive EF back catalogue, which in turn also works with 3rd party EF lenses.

Do you really think Sony's business model is sustainable? Fast forward 5 years when the vast majority of FE lens purchases are 3rd party - where is Sony's incentive to carry on?

We're in a diminishing market. If locking in RF revenue to Canon keeps them investing in the platform, then that's absolutely fine by me. Photography is a business after all.

There have been a lot of third party offers for EF for decades. Even before the digital boom. And canon was still producing new lenses and it was still sustainable. So why won't it be in the future?

Canon never opened the EF protocol to 3rd parties - hence those lenses had to be reverse engineered to work on EF, and never performed quite the same way.

Sony has fully opened the FE mount, meaning 3rd party lenses can perform identically (or better) than native Sony glass.

My understanding is Canon have done exactly the same as the EF mount and said "here's our patents, if you want to try and work around them, fill your boots".

Sorry but the sigma art and many recent tamron worked perfectly with the DSLR.

Sorry but its VERY well documented that the ART lenses had inconsistent AF, especially on the outer AF points, and is the reason I stay away from them on my DSLRs Christopher Frost 85mm F1.4 ART review go to 2.20 min

what is very well documented is that canon cameras had a really bad outer AF points.

try the same lens on a 1D and tell me what you got.

i think you are thinking of the 1Dmkiii which many units were recalled with a folt

The af points on the 1D are all Cross-type. On the 6D only the central one is. So even with canon lenses, the outside af points were not reliable. That’s why for decades people only used central points when needing reliable AF. And even then, it was not 100% reliable even with the best canon lenses.

Try the same lens on a body where all focus points are cross-type and let me know if it’s still inconsistent.

If it’s the implementation of the protocol and not the camera AF system, the same lens would have the same problem with mirrorless cameras, right?

No if you watch the vid i posted the sigma lenses AF is very reliable on a DLSR but only in live view mode while LV mode on a DSLR works in the same way as the AF on a MILC

so there you go. The af on the lens is reliable if the af system is reliable.

if the af system has problems even with canon lenses, you can’t expect it to be perfect with other lenses.

OK i will rephrase it... it is very well documented that the sigma lenses can be much more unreliable in the AF  especially in the outer AF points than the alleged unreliable AF system on Canon DSLRs with canon lenses however its well documented that on DSLRs sigma lenses  AF works much better in LV on DSLRs and on canon MILC as do canon EF lenses ..

it dont matters what the reason is for it ..... whether its the body's fault or the lenses' fault or canon's fault or sigmas fault or whatever...

i would not put it past canon to trip 3ed party lenses up like in 2003 ish when every sigma lens  ever made stopped working on the newly released 10D,300D and i think 1Dmkii

sigma found this out at a launch show when folk that buy a new canon body went over to the sigma stand only to find non of the lenses worked ..sigma had to rechip them ..thats why you can upgrade the firmware in meny 3ed party lenses by USB today

Attention Dislexsic i mean dyslexic person... This post will have many although spell checked, spelling and grammatical errs ..its The best its going get so no need to tell me it is bad I know it is .....................................................................................................
the EOS M is not dead and wont be for a long time ....as long as you don't want a flagship camera with a VF...if that's the case it died sometime ago
My 5D IS a MK1 classic

There is no argument for FF vs APS-c (or m43) with shallow DOF..as it's a law of physics and a very subjective personal thing if you want to make use of the shallow DOF only FF can offer

If you wait for a camera that will tick all your boxes ....by then you will have more boxes to tick..... so the wait continues .....David Appleton
