Hi Guys,

Can this lens be used on Canon EOS R?

do you think there will be any lagging / slow in auto focus?

Hope to hear your thoughts

many thanks!

Ok so Ive waited for a Canon Mirrorless camera all this time, In the meantime using the Fuji system, which is ok, but not full frame.
With my Eos lenses gathering dust!

Along comes this all singing all dancing Canon R........wait a minute the most important feature of a silent camera...." Single Frame, silent mode??? Are you kidding me, what is Canon doing? ......Saving pixels!

Now i hear they've thought about it, and are adding a firmware upgrade at some point??? So the handbrake can be turned off and it will be hopefully able to shoot, i hope more than 3 frames per sec!! But i guess more than one frame.......is a bonus!!! When do we expect this firmware?

Didn't Canon do the research and ask what was the major points of the Mirrorless camera is, ...but the silent mode!

If they dont get this right now.......the loyalty of pro camera users has gone for good, to Sony, Fuji who know the Mirrorless market, and what is needed.

Doubtful. They already provided a solution with the adapter.

+1
Just glue your adapter of choice to the lens, job done!

Im thinking:-
EOS Rs
50+MP sensor with BSI or new tech
8-10 FPS(maybe in crop mode)
Dual DIGIC8
NO IBIS
Dual SD Cards
Bare minimum video specs due to sensor res
Possibly slightly larger body(due to dual cards and processors)
HiCap Battery(still LPE6 size)
Real Joystick
Larger Higher Res EVF

I’m fairly close to you on this. Differences: 8-10 FPS with AF locked, 5 FPS Servo with tracking priority. Bigger battery ( can’t get significantly more power without getting larger).

Photozone aka optical limits has finally reviewed the lens: http://www.opticallimits.com/canon_eos_ff/1045-sigma100400f563c
They found what I found in the 4 copies I looked at courtesy of the local dealer; the IS in the viewfinder is terrible and not much good in practice. Their summary is: "Thus even though the Sigma is quite capable in optimal conditions, we'd suggest to look elsewhere."
My experience of the Tamron 100-400mm f/6.3 wasn't good either. I made the mistake of buying one because I thought it would be light for travel but eventually sold it as the tracking of birds in flight was hopeless. The Sigma and Tamron 150-600mms are much, much better and really worthy of consideration.

I almost bought the Tamron 100-400 recently also for an easier lens to travel with but backed away from it. I've heard too many negative things about the Sigma 100-400 and never considered it. The most recent Canon 100-400 is on my wish list.....

I do have a Sigma 150-600 C that I got a few years ago and my copy seems really sharp even at 600mm, I really enjoy the results I get with it most of the time.

I do have an issue with it hunting occasionally though if I'm not in great light conditions, I also need pretty good light for it to track well most of the time. I normally just use it on bright days to keep my frustration level at a minimum

I use it on my 80D most of the time and took this squirrel image at 600mm -
f/6.3 - ISO 640 - 1/80sec.

The squirrel was about 20ft away from me in this photo......

Says -3 elsewhere.

-6EV is specified when using an f1.2 lens while the -3EV on others (say the 5D Mk. IV) are specified using an f2.8 lens which explains the different values.

Rumours so far predict 2 mirrorless bodies, but guesses on release date for the second are anywhere between Spring 2019 and .....2032

I've heard very good things about the Tamron so hope the 11-24 lives up to my billing !

It was a good lens, no doubt. But I like the idea of the verticals being verticals without having to use transform in PS and it getting cropped in. It might have been a year ago when you explained projection distortion to me. Thank you.

So many fantastic lens choices and not enough $.

As a 7d2 shooter(would love a 1dx2 but unfortunately selling the wife won't generate enough cash) I can tell you that there is not a mirrorless camera on the market that could tempt me to change systems. Yet. Ergonomics are so incredibly important to a wildlife shooter and it seems non wildlife shooters simply cannot comprehend how important the feel of the camera is. With a grip the eos r actually looks manageable but it would have to tick a lot more boxes as well. Weather sealing. frame rate. An evf that does not hurt to look through for hours on end. ZERO lag when panning at high speeds. Buttons in perfect places(although that lens/adapter ring looks to be the shizzle). There is a helluva lot more required than just whacking in an evf nad some useless focus peaking.

Agreed.

Can they get over the 125 sync speed.

Don't know whether the GN decreases that much, but maybe the GN is only 10 in the 24mm Position.

Sorry, I don't understand what you mean.
Normally you can read from the spec sheet how the GN is determined, eg. here
" The Guide No. is approximately 49.2 ft./15m at ISO 100.

The maximum Guide No. is approximately 196.9 ft./60m at ISO 100 and 200mm flash coverage."

For further details see also here.

Really ... nobody posted here ...

hard to eat that crow I guess ...

Remember the M? Canon introduced it and it sold well, and they maintained the existing Rebel lineup and EF-S glass BECAUSE IT SELLS WELL!!!!!

Canon has now introduced the R, and (presumably) it will sell well. They will keep the existing XD bodies and EF lenses BECAUSE THEY SELL WELL!!!!!!

Canon does not have to choose between mirrorless FF cameras and mirrored FF cameras. There is a profitable market in both, so there is now way that they are going to leave either market unless it becomes unprofitable.

And keep in mind, that at the same time they have introduced the R camera, they introduced a pair of EF big whites..... these are lenses that take many years of sales to recoup design and production costs. They are obviously planning to be in it for the long haul....

Michael Clark · Sep 5, 2018

I think it is very likely *both*.

axtstern · Sep 5, 2018

So I assume that the camera can identify the Canon EFS Lenses but will not detect the Sigma and Tamron APS C Designs

The 1DX2 already can shoot 16 fps in Liveview with AF working ...but not under Servo AF. I've been looking around for a published actual top speed with Liveview burst shooting doing the tracking work and I can't find it at either TDP or Canon proper. (Anyone know?)

Hi just checked the manual, and it says continuous shooting during live view will lock AF and exposure, so on that basis live view can not track but can do 16 frames per second, might have to wait until digic 8,9, or 10 for that to happen :-(

Canon stressed the new mount allows for new high-performance lens designs, not small light lenses. That's probably why there's no compatibility with the EF-M mount which is designed for small/light lenses.

IMHO some smaller and lighter lenses will come, but from a PR perspective, they would have not been the right choice for the launch - imagine the "umpf!" if Canon had announced the camera with a 50/2 and a 28-85/3.5-5.6... even if they were the lightest and smaller lenses ever designed.

Asserting the capability of the new lenses from the beginning was a smart move, even if the first R camera is certainly not the highest-end model, as usual with Canon when a new line is released.

That's my sense also.

Sure we can, Metabones have been developing adapters since many many years with several versions and yet it still not works that well. And as the cameras and lenses get more 'clever' the drawback of an adapted lens from a different manufacturer gets even more severe.

Canon and Nikon are both fine systems with many lenses to choose from and use. Anybody can switch if he/she wants to but in 99% of the time it's not really needed (for instance, if that little difference in dynamic range matters that much to you, why are you still shooting Canon) but people do it, because it's fun. Also great for YT (especially starting it), generating views and arguments in the comments.

Unless it's a specific case (let's say a particular tilt-shift lens or something that still won't perform the same with the other sensor's AA filter thickness) it is money down the drain with lenses that focus and zoom in the complete opposite direction to the other and introducing an adapter (and an expensive one at that or there will be tolerance issues) that at times will just freeze up the camera.
It's totally for people with more money than sense but, in that regard there is a certainly a market for it...In that case with that much money it"s much better to buy Leica M lenses instead as at least they won't have any operational issues and they also also one of those rare lenses that are actually sized well for these cameras, so there is an actual case for them. Even if they don't perform perfectly, it will be probably a bit better than Sony.

Aftermarket lenses like Sigma ART might get converted or adapted with their own adapter the new mirrorless mounts again and you can use those as well, they do want to shift those to whatever systems, if they are able to make them work. That makes sense.

If one is intending to use manual focus for video or photo, than it might also work ok (but again, in this case why choose that camera and deal with this issue instead of the other that has a way better 'official' adapter with ND and it just works at all times, which is kind of important for most people)

I acknowledge your points (don't agree with some but we'll leave it at that) but, IMO they an EF-Z adapter is inevitable regardless. I guess we'll have to see when it happens about how good it is and how much it is. For now off course, Nikon/Canon being usual, are not letting 3rd party have access to the specs so it will take some time before they reverse engineer them anyway.

I am a lifelong canon user since my original ae1-program and a current 5D Mark IV user (and M3 owner). I've been observing the developments in the market for the last couple of weeks.. Like most of us Canon users I have had a degree of envy over sensors in the likes of A7riii and D850 but my camera needs to withstand the rigours of sea, salt and rain a lot so kind of rules out the Sony even with the supposed improvements in weather sealing...and Nikon Z seems like a futile attempt to prop up sales for nikon purists which won't succeed in dragging back lost users nor converting any from canon or Sony.

I was hoping Canon would take this challenge seriously rather than an arrogant stance. It appears to me that they have and for what I do that the R is going to be a great option.

My camera spends almost all its life on a tripod... Therefore I don't need IBIS. I switch off IS on the L lenses I own anyway.

I almost always use a remote shutter and live view and the 5DIV has great auto focus even through 6 & sometimes 10 stop nd filters so having better auto focus on the R will mean never having to manually focus in low light. Battery life will be no different on the R to the 5DIV in live view tbh anyway and I have plenty of spare batteries.

When not on a tripod I tend to shoot in slow speed mode and the silent option will be brilliant for candids.

The resolution of 30mp is good enough to be comparable to the 5D and when the Pro body comes out I expect that to be around the 50mp range.

Its smaller and lighter.. Travelling with the 5DIV and lenses is tricky for a lot of airlines and lugging it up hills is tricky for me... If that cuts weight then great - I am not a spring chicken anymore

I have never shot video so I have no interest in that.

I assume the dynamic range will at least be as good as the 5DIV and that is plenty for me although better is better

I for one will get one on preorder and use it alongside the 5DIV snd see which one gets taken out to play more often then probably get the higher spec one when that is released.

Just my two pence worth

"Focus guide" is not focus distance display. It is a set of markers indicating to which direction to adjust the manual focus at the selected focus point and by how much.

Thanks for clarification. From the video it's clear that EOS R supports both functions.

"This, the element I found most difficult to get my head around, was the thing that in the end I fell most in love with – there are 5,655 selectable AF positions with touch and drag, that’s incredible to me. Heading out for shoots in recent weeks since I’ve returned the Canon EOS R, I have found myself a little frustrated with the constraints of using the joystick on my Canon EOS 1DX Mark II."
