Tamron 100-400 on R bodies?

back and arm becoming more issues as I age :( ... the focus engine is a huge improvement.. not perfect as some credit, but huge improvement. However there are so many options with autofocus it gets its own menu now... learning to maximize it really takes some getting used to and knowing/remembering when to change it takes a bit of getting used to... like changing between people and animals .. now programmed in custom, but also the continuous autofocus can be outright annoying at times yet horribly useful... it keeps trying to focus on something when you point down or away from your subject or just have the camera on and walking so you're ready.. but damn useful when you are ready. another is learning to set a start area for the focus and then compose and have it track vs it trying to figure out what you're trying to focus on.. how well it flips/locks on etc.. still scratching my head on many options

Yeah getting older isn't fun... lol. You'll get used to it over time and the custom buttons make it so much easier. For me it took a bit of getting used to mainly due to the location of Sony buttons being in my muscle memory but I'm already more used to the R6 now. The tracking is definitely amazing though and I really love how it just sticks to the subject. I feel like that plus the 20fps would make shooting wild life even more fun.

R6 Intervalometer Questions

Thanks for the detailed reply!!!

Battery life is a huge issue, and definitely a concern. The housing will definitely not allow for any extra battery grip, or any way to change batteries underwater. Fortunately, a "long" shoot is 45 minutes. It looks like the R5 and R6 use the same basic form factor of battery, so probably similar time. Is there any way I could ask you to run a time check on it? See how long it'll do 1 second intervals before the battery dies?

Can you get enough review time on a 1s interval to even be useful?

I'm probably not patient enough to do a full test for you but some additional considerations..

power draw and how long it lasts likely depends on what it's doing for you at the time.. live view or electronic view finder, constant autofocus, reviews, jpg vs raw etc etc. I've only done small dives but I imagine it's useless to start it when you first get in and only really valuable once you can see the ground which would mean only short time periods, but I'm not entirely sure of your case scenario.

if you're looking at figure out if the lights are in the right place etc, keep in mind it uses live view.. you're seeing it live all the time and its pretty accurate for me (though there is more than one mode I think), maybe it renders the review question moot.

intervaluemeter I Think turns off once its done and you manually have to turn it on again via the menus.. not sure if there is a way to automate this.

it works by how long between each shot (1second to hours between). .. and how many shots (1-98 and then 99= infinity until you turn the camera off I believe)

you should consider renting an R6 or R5... given how specific your cases are, it's likely worth your while.. larger cities often have shops that rent equipment.

also can't see anywhere to program a button to enable / disable intervaluemeter.. seems to be menu only?

Do you have an RRS L-bracket for the R5 or R6 pre-ordered?

I’m glad you found peace! How do you like the screen movement?
I've spent some time paying more attention to the screen movement. For me, whether on a tripod or kneeling at an odd angle, while there are a few minor restrictions to perfect positioning, the screen movement is fine in about 90% of cases. (And I like how the tips at the gap for the screen are beveled better than on the Kirk.)

But that is for stills. For video, I don't have much experience, though I did use the flippy screen to take some video of how lens IS components shift about. I placed the camera on a tripod, pointing down, and I had to come around to the front of the setup to hold and move the subject. I was able to move the screen so it was very easy to watch as the video recorded.

Sorry, but that L-plate you showed is way more complicated than I want full-time on my camera for stills, and I'd rather have a little restriction of the flip screen than any restriction around the lens barrel. (But I do like the option to protect the ports!)

Truly, the ergonomics of the R5/R6 L-plate make it a great choice for those who want to mount it and forget it. "Elegant" is the single word I go with.

Patent: Lots of super telephoto lenses mentioned

Any chance we'll ever see the EF 500mm f/4L IS III and/or the EF 300mm f/2.8L IS III come to fruition? Would be nice for Canon to finish the "III" line of the EF big whites (and all of them actually being the same shade of white) before abandoning the EF line. I would think that these two lenses would have been at least in some stage of development before they decided to scrap EF and go all in on RF and mirrorless, no?
More likely to see those two long white fast primes out by 2023 on the RF mount before the 2024 Summer Olympics in Paris.

Need your advice on moving on from 5D3 to R5

Ok, so to conclude, I have placed my order. My budget is a bit tight so I have ordered the R5 Body, The RF to EF adapter, a spare battery and a Sandisk 512GB Cfextreme card. I will use the 24-105 from the 5D3 for now until I buy the 24-105 for the R5. I hope to get everything by Friday.

Wish me luck

Now I have a lot of new stuff to read up/study :)

Has anyone purchased a R5 in India?

Hi,

Looking to get input from those of you who have purchased the Canon R5 in India. Would appreciate if you could give me the following information:
  1. City where you bought it
  2. Dealer name
  3. Price
  4. Did you get a lens? If so which one and what was the price?
  5. What cards did you get and at what price?
In addition I intend to get the EF to RF adapter and a spare battery or two. I think I will purchase soon so wanted to get this input.

Thanks in advance.

R5+ RF 70-200 Shooting speed and AF accuracy in servo mode ( quick-moving targets)

Hi!
I am interested in whether the AF accuracy really depends on the shooting speed and in the point of using H+ mode for quick moving subjects ( cars, skiers) etc.
From my experience I get only about 50-70% properly sharp shots when shooting fast-moving objects that approach me like cars with H+. It looks as if the AF motor is not speedy enough to refocus between the shots and around each 2'nd or 3'd shot is to a various extent back focused. It is especially pronounced when using mechanical shutter. (in case of mechanical can it be because of the blackout, which steals the focusing time from the AF? ) The keeper rate does not really depend on the focus mode or scenario.

If I use H mode I have a bigger % of keepers. So for me its is actually not much sense in H+ mode for quick ,moving subjects, as I have pretty much the same number of keepers, just more junk with H+ that eats memory.

Does anyone have the same situation? What is your keeper rate?

The Canon EOS R5 scores Canon’s best sensor score at DxO

I can't compare to Nikon, Panasonic, or Sony, but I can say that the R5 produces images that not only look great RAW, but are very easy to work with--even at higher ISO's. (Shadow and highlight recovery, noise clean-up, sharpening, colors.)

What surprises me above all, and should have weighed huge in any fair assessment, is the ability to use 100% crops from the R5. I've had the 5DIII and 5DIV--they do not come close. Can the brands with higher scores do this too? If so, great for them.

Here is an example of approx. 100% cropped, ISO 640, and, imo, it is perfectly usable online. They print fine for 4x6 and 5x7. I've done so. What an amazing "cheat" this can be when we don't frame optimally!

View attachment 194798

The R5 has surpassed my wildest expectations, and I've only just begun to explore its potential.
I'll second your praise of the R5 regarding shadow recovery, etc., even with cRaw which is now my only way to use it as I need the smaller size files. It's really great!

My previous camera was an EM1_II, and while it had a lot of benefits it had a poor shadow recovery (IMHO) which was only saved (for me) by the use of PL3 and their "prime" noise reduction. Now I get to have an already stellar R5 file and PL4 "deep prime" noise reduction for vastly better performance. It's a great day to be a photographer! :)

R6 SD UHS-II Problems

Yes I often switch between video and photo these days. I used to only do video on particular occasions as my mum and dad each have their own business so I did commercials for them on my 6D, then 6D II, then I sold all my EF lenses apart from the 24mm 1.4 II and heavily invested in RF glass and bought the R but otherwise just photos in private life mostly for fun and for my wife’s Instagram channel but since the beginning of this year I am a first time dad and having the little one makes me switch constantly between video and photo.

I really like the R6 but I still also have my R and I gotta be honest, there are certain things I do find better on the R.

I am sending the two Lexar cards back and I will get myself a 64gb Sandisk uhs-II for certain occasions like mentioned here and otherwise use my older Sandisk Extreme Pro cards I also use with the R.

The Canon EOS R6 sensor scores a 90 from DxO

DxO scores are in agreement with your iso observations. The R6 is their highest rated Canon camera for iso performance and the 7DII is miserably low down, 3394 vs 1082 in the "sports" column (substantially due to the crop sensor being 1/4 of the size). DxO scores for individual aspects of sensor performance are usually fairly rational, it's the overall score where they somehow weight those components that rankles because that is subjective rather than scientific.
Yes. So it seems. I should find out this afternoon when i get to do a few hours of wildlife shooting. Will post the results in a few days

Patent: Canon shows off a new approach to the modern shutter button

All physical buttons can be removed.
A touch screen can do everything.
Perhaps, but there are many cases where you don't want to.

Think about action photography, i.e., sports and wildlife. Things are happening quickly, and having a physical button or a click-wheel allows the photographer to find and change settings using only their fingers without having to take their attention off the action in front of them.

A touchscreen interface might allow the same settings to be changed, but it requires the photographer to focus their attention on the screen in order to find the right "button" (since there's no "feel" to it) and then slide and swipe to change settings. Great shots could be missed during that time, and that's food on the table for a working professional.

Also, all touchscreen capabilities go out the window if you're wearing gloves. Even the so-called touchscreen gloves reduce your touch accuracy.

Settings not glitches

The R5/R6 bodies add some complexity to taking photos.

[...]

Any other examples?
I don't know if it is really a new thing. It is just a result of Canon's stubbornness. For situations where some confusion may arise, they rather take a feature out.

Examples from my 80D: Not being able to use tracking and face AF and the electronic level at the same time, for example. Or not being able to use auto ISO with flash.

When you think about these, they sort of make sense. You need exposure simulation to view a histogram, because the histogram is based around the LiveView image (or the JPEG you could take at the current moment, if you will). If you turn it off, the camera may either have to display the false histogram based on the false exposure shown on the screen, or it would have to compute a second image with the right exposure, swallowing resources and causing a confusing mismatch between the image on screen and the histogram.

And something like RAW histogram isn't even an option.

Face AF and electronic level both draw a lot of stuff one the screen, so Canon probably felt it becomes to cluttered when they could both be turned on.

The flash thing has been explained to me in the past, but I still don't understand how it improves the camera to lock it down.

Histogram not Displaying / Missing screen info

Did you find your answer yet? I saw a thread on DPR about this, checked mine, and sure enough, Exposure Simulation must be Enabled, not off or only during exposure. Only the top option allows the histogram on mine to be visible in the EVF.

Thank you very much. No I had not found an answer.

EFCS vs mechanical shutter DR and bit depth

As far as I know ES doesn't let you shoot single shot. I think it's 20 fps mode only. Could be wrong since I rarely use ES.
I tried in One Shot and it only takes one. Like you, I don't see much reason to use it--and especially just one shot at a time.

But a delimiter would be nice. If the actual rate can't be slowed, a menu option that allowed a set number for a burst would be better than what we have now.

Can a lens make a camera's shutter behave differently?

Sounds like a communication problem.
The lens is an ef mount and because it's not a Canon lens, the comms protocol between the Sigma lens and the R6 is relatively slow, and as the camera won't take a shot until it gets focus confirmation from the lens - the camera won't allow high speed shutter to work.
The lens is fine for one-shot mode, but it won't focus as fast as an RF lens.

Canon R5 focus assist lamp half-blocked by rf 24-70 and RF 70-200

For better or worse, it is the same on the R, R5, and R6.

I have not noticed any difference in focusing quickness or accuracy away from the center, but this is an interesting question.

I guess that focus sensivity depends on the light fall-off, especially in case where focus assist is used and covers only the central area well. It is easy to check. Just try taking pics in a barely lit room in the evening.
