Yes, you will need to play with your aperture and ISO settings to get the right exposure. Your R6 has vastly superior capabilities to any phone out there. If you are a newer photographer, there are many resources on the web to learn how to perfect the craft. Look for exposure settings and you will be heading down a rabbit hole that is vast but worth the journey.

Thanks. I played around with the iso settings when I was shooting the video. My camera lens only goes to f4, while the phone can go to below f2.8. I didn’t play with the shutter speed or white balance, though I will try adjusting those next time. Eventually I want to get the RF 70-200 f2.8, but that’s a ways off. Do you think that lens using the f2.8 will make a significant difference?

RF would give you better stabilization than an EF lens that does not have coordinated IS, but that has nothing to do with the flange distance.

I was talking unstabilised RF lenses. I'd gladly take a 200 to 300mm unstabilised RF lens if IBIS allowed me to drop shutter speeds to around 1/100th and, at least up to 200mm I know it does, because I paired my old EF 70-200mm f/2.8 L USM with my R6 for years and could easily get to 1/50th.
If sacrificing IS allowed new groundbreaking faster lenses, and/or more interesting zoom ranges, within these limits I'd happily accept such trade-off.

The IBIS seemed to offer about two stops. To be honest, I was thrillled that a 15+ year old (adapted) third-party lens worked as well as it did on one of Canon's best new bodies.

Exactly, I had a very nice experience too, with my old EF 70-200mm non-IS, in that regard. 1/50th was perfectly fine, and I could get some keepers at slower shutter speeds too, just not as consistently.

I'm aware, that's why I mentioned my experience with the old EF 70-200mm f/2.8 L, that took me to 200mm with IBIS alone, and using the adapter. I still had 2 stops of stabilisation - I always found that to be quite good, all things considered.
A RF lens would stand closer to the sensor, which would probably allow IBIS to be slightly more effective, perhaps even getting two stops at 300mm. I'd take that

I (still?!) own a decent copy of the [nonstabilized] TAMRON SP AF 70-200mm F2.8 Di LD IF Macro A001...and upon acquisition of an R5MkII body (months ago) I did a bit of (non-rigorous) testing of this lens.

What ‘real world use’ would differ from CIPA by 8 stops?

Click to expand...

It could just be the weight of the lens.
That is not at all a factor in the CIPA test.
Robots do not get tired.

neuroanatomist said:

Is that because of the reliance on IBIS with MILCs?

Click to expand...

I think that is true.
Tamron had a lot of SLR lenses in the standard range with IS.
They have very few in mirrorless.
Canon has gone the other way, but they have many cameras on the RF mount that do not have IBIS.

I was replying to someone who stated, “I was shocked to see how I can see the lack of IS on the images…” Sure, maybe someone using the R5II + 28-70/2 gets 6-stops of stabilization and not the 8-stops per CIPA’s testing protocol. What ‘real world use’ would differ from CIPA by 8 stops? Having advanced Parkinson’s disease and taking pictures while riding a mechanical bull during an earthquake?

Click to expand...

The distance from the sensor at 300 mm would be exactly the same.
The back focus makes up for the flange distance.
RF would give you better stabilization than an EF lens that does not have coordinated IS, but that has nothing to do with the flange distance.

IBIS is most effective at shorter focal lengths due to the nature of how it works

Click to expand...

IBIS is most effective at standard focal lengths, but I guess that it was what you meant.
I wish Canon would let us turn IBIS off and only use lens IS for UWA.
*I more than wish, I have requested several times.
Canon responded by improving their IBIS, but not enough for me.
A lot of more influential people than me really like being able to turn off IBIS from the lens.
I use my R5 C or PowerShot V1 for UWA, so it does not impact me personally

neuroanatomist said:

It's not that Canon didn't tell us, it's that Richard didn't pass along the full explanation. He hints at it, though, right at the start: "I had previously discussed these as quarter-wave optical designs...," in reference to the quarter wave plates (QWP) that convert linearly polarized light to circularly polarized light and back.

Details are in the patent, and the light manipulation you're missing is polarization, more than once in the optical path and both linear (POL) and circular (QWP2, QWP1), plus selective reflection/transmission.

Thanks, this now makes sense for most items. The items that make my head scratch are:

The sensor only receives horizontal polarization component of the light, so you basically have polarization filter inside your lens which you cannot remove.

But furthermore, switching from linear to circular (or back) should reduce light by 1 stop, so you wouldn't get much light in the end. Counting the light path for conversions: E D B B B

C (HM) probably also cut 1 stop on that first pass but I'm not sure so I'm leaving it out the calculation.

So that's 5 stops (or 6 if count HM) of light right there. Maybe I should go read the patent as this is interesting although I'm not yet sure if it's practical.

Also, QWP are fairly frequency sensitive so I'm wondering how much different the far ends of light spectrum will behave on that.

neuroanatomist said:

Your camera has IBIS. For the 28-70/2, the camera’s IBIS provides the maximum possible stabilization (8-stops based on the CIPA standard) that can be achieved by any current Canon system including the RF 24-70/2.8 IS. In other words, putting IS in a future 28-70/2 II lens will have zero benefit unless the lens is used with a body lacking IBIS (like the R8 or C50).

It is easy not to realize that as a Canon user, but lens IS is very rare in other camera systems under 200 mm of focal length.

Click to expand...

Is that because of the reliance on IBIS with MILCs? Is that also true of Nikon's VC lenses (since they transitioned to MILCs on a similar timeline to Canon)?

Tripods come in many sizes. Maybe you just need a smaller one?

I have seen it said that cinema cameras are usually used with rigs (is that the word?) to stabilise them?

Click to expand...

Cinema cameras are often rigged up because they do not come with everything we need.
It does add to stability, but that is not the main purpose.
Canon Cinema EOS cameras generally come ready to use out of the box.
I use the R5 C handheld and ready to go.

scyrene said:

Cinema lenses don't usually have IS, do they?

Click to expand...

Canon has plenty of cinema lenses with IS.
They are very popular in ENG, wildlife, and sports.
You are correct that most cinema lenses do not have IS.
However, that is also true of most photo lenses.
It is easy not to realize that as a Canon user, but lens IS is very rare in other camera systems under 200 mm of focal length.

By the way, isn't every lens changing magnification when changing focus distance?

I guess the assumption is indeed that if the 100 1.4 will materialize, it will be an L lens, which makes it a difficult proposition in my mind, slotted between the 85 1.4 VCM and the 135 1.8

Click to expand...

I see it as between the RF 85 f/1.2 and RF 135 f/1.8.
Although it would really just be part of a set of f/1.4 VCM lenses.
There is no 135 f/1.4 VCM.
