Canon EOS R6 V Specs: Active Cooling and more…

[Canon Rumors]

STM can be quick, but it is not fast. It's also a mechanical gear-driven focusing system that will fail with time. It will last the warranty period, so what does Canon care? Might even last until replacement parts are no longer available. Oh no, you have to buy a new lens. I'm sure Canon will be most distressed.

So you've never used them. Got it.

The only company that will officially service lenses forever is Leica (I don't know about cinema lenses from the likes of panavision).

Canon serviced the EF 50 1.4 for like 30 years (and probably another 5+). They still service a bunch of other lenses released 20+ years ago. Just to let you know, USM motors fail too. Anything that moves will eventually fail.

I would certainly hope so, but Canon has put STM AF into really expensive lenses such as the $2400 RF10-20/4L or the $1900 RF7-14L. I won't be surprised if they put STM AF & PZ into this $1400 lens.

I own and use the RF 10-20 mm f4 lens and the focusing performance is excellent. At those focal lengths three is very little movement in lens elements so STM makes a lot of sense.

So they are going to price it ~$100 above the Sony 16-35/4G PZ, a lens with six XD Linear motors in it, four for AF and two more for zooming. Canon better have upped their game as far as their PZ system goes, the PZ lenses released to date have been...underwhelming.

And ~$200 more than the 20-70/4G. This one lacks PZ but has more range. Great travel lens, pairs well with the 70-200/4G II Macro (0.5x through the full zoom range).

Perhaps Sony is paying you to troll here, but I hope not – your trite, repetitive postings mean they’d be wasting their money. Sad that you apparently have no better use for your time than trolling this forum.

Seems like Canon created a nomenclature issue for themselves. The successor to the R6 III would be the R6 IV, right? And after that? The R6.1?

Relatable.

I've used plenty of STM lenses, including ones by Canon. I own a number of STM lenses, though I'd certainly never spend $2400 on one.

Canon services lenses that are still in production, and guarantees service & parts availability for some number of years after production ends. If the parts supply lasts longer they offer service longer. Otherwise things wrap up and no more service (or parts) available.

And yes, USM motors fail. It was a huge problem with the first gen USM "big white" super teles as well as the 50/1L and EF 85/1.2L. The lenses that had fly-by-wire AF. Just like all mirrorless lenses are. When the AF motors failed, the lenses became paperweights because that killed the MF too. We will all face the same problem in the future with every mirrorless lens.

And yes, anything that moves will eventually fail. But AF systems that are powered by electromagnets and move back and forth on smooth rails are a lot more robust than ones full of plastic gears and a screw drive. More moving parts ("anything that moves", as you said) means more things to fail.

STM is the cheapest, slowest, and most mechanical form of AF that is used in MILC lenses today. It's what Viltrox puts in their cheapest lenses, and it's what should be expected in lenses that cost up to $200 or $300. The amazing Viltrox 14/4 that I own (paid $160 for it brand new) has STM. And that's fine, it's a $160 lens. But a $2400 lens deserves a better AF system than STM.

And while you are correct that the 10-20/4L does not require a lot of movement of the focus groups, the same cannot be said for the 800/11, a $1200 lens that also uses STM for AF.

You know it's okay to call Canon out on this stuff, right? They're charging you premium prices but giving you bottom tier AF.

I sometimes wonder if Canon pays you guys to post here. You're like some sort of weird corpo shills, or bots who have been programmed to ignore reality. It's weird, but makes me morbidly curious about how it works.

Based on Google AI I would not disregard the 10-20 mm f4 lens:

The Canon RF 10-20mm f/4L IS STM is absolutely not considered poor quality. It is widely praised for its exceptional sharpness, fast and silent STM autofocus, effective image stabilization (IS), and lightweight design, making it a premier choice for architecture and landscape photographers.

Way back in the day the D60 (2002) and 60D (2010) caused confusion too. Even today it causes confusion, many people have no idea the D60 existed and assume you mean the 60D.

...programmed to ignore reality.

You are the expert at that around here. For example...

In the mirrorless world, Sony still sells more MILCs than Canon does. It's now very close, and maybe next year Canon will overtake Sony in MILC sales, but they haven't done so yet.
