EOS R System: Experimenting with adapted lenses with mirrorless, thoughts? Experiences?

I have bad eyesight too and I don't think you need focus peaking with magnification, but that's me. Why don't you rent an R5 from lens rentals (or is there an alternative place?) ?
That's actually an excellent idea!!

I think I will rent one maybe in the near future and play with it.....

Yep, Lensrentals and Lensprotogo ....they're actually owned by the same company, but they often have different sales/.coupons going so it pays to shop between them.

Sometimes one has items the other does not...and one factors in shipping in the price while the other does not, so, it pays to compare the total pricing between them with whatever coupon(s) are out.

Canon Introduces Their First Dual Fisheye Lens for Stereoscopic 3D 180° VR Capture in 8K

Is there a higher quality version to download and view on my quest 2? This video looks like absolute garbage in VR, from I am assuming youtubes compression.
I don't know if there is a higher quality version, but you are right that it looks like garbage, and also that it is from compression. Whether or not it is youtube's compression or something Canon did is hard to say. I definitely occurred to me when watching that it was weird of Canon to use such a poor quality video for a lens advertisement.

I don´t understand the Canon RF Lens Philosophy

A half dozen is for amateurs. A dozen is the minimum if you are really serious. :) Still looking for that Tardus bag though, you know, the one that's bigger on the inside than on the outside.
Indeed, if I was to make a move into manufacturing in the photography world I think cameras and lenses and the like are for dummies, bags are where the big bucks are!

Stock Notice: Canon RF 400mm f/2.8L IS USM & Canon RF 600mm f/4L IS USM

Question 2: Canon once claimed that EF lenses work as the way the supposed to be adapted in Mirrorless body, even tell all lenses released within 10 years ago capable of shooting 30 fps, unlike competitor that only work for selected lenses
If they claimed that it would have been relatively recently, since only the R3 is capable of 30 fps. But for the 20 fps on the R5, the majority of EF lenses are as capable as RF lenses at being able to achieve 20 fps (the big caveat is that 20 fps is situation-dependent, so the way Canon phrases is it 'continuous shooting speed of max. approx. 20 fps less likely to decrease' for a list of lenses that includes EF and RF lenses (link). Canon has not shared a similar list for 30 fps on the R3.

Here is the official Canon USA press release for the Canon EOS R3

Mechanical shutters do not provide perfect geometry, either. If one looks at images from the 1DX Mark III taken using the mechanical shutter just as critically as one looks at images taken with electronic shutter, there's not that much difference between the R3 with ES and the 1D X Mark III with MS.
This is what I consider too much for the intended audience. I can understand why they saw this as a marked improvement, however, I don't see it as terribly good. Let's just say a global shutter has a real value in this type of shooting.

Patent: Canon RF 180mm f/3.5L Macro and Canon RF 200mm f/4L Macro

Back in the days of film, when we were generally limited to ISO 100 slide films, most people used flash to enable a usable combination of small aperture and freezing movement, but from my observations, the vast majority of people nowadays prefer to shoot by ambient lighting, unless they are working indoors or in the darkness of a rainforest interior.
…or shooting at high magnification. For example, shooting with the MP-E 65 at a diffraction-friendly f/11, the effective aperture at 5x is f/66. That’s why I use the twin-flash.

Adata SDXC 7.0 express cards announced.

CFexpress type a adoption is still too slow and other than handful of Sony Cameras no one is adopting that standard so let's see how SD 7.0 is adopted.
My impression is

1. UHS II cards will take a performance hit in SDXC 7.0 slots, so some customers would upgrade cards. Unless SD 7.0 comes in at a much lower price, customers wouldn't prefer SD to CFExpress. On the contrary, owners of such cameras as the R5 would rather buy more of the CFExpress cards they already have.

2. Given a device can dissipate the heat (with similar size, I don't see a reason why just one of the two would create a problem), CFExpress type A vs type B is a matter of designing different plastics.

3. There already are CFExpress slots and card readers on the market and manufacturers are already working out the problems. Another standard is another headache, which I don't see how they would justify.

4. Micro SD is loosing market with some smartphone manufacturers dropping it, and nobody making A2 compatible slots*. At some point laptop manufacturers will probably follow suit and drop the slot as well.

* I know there are A2 micro SD cards on the market, I haven't heard of any gadgets with slots that benefit from it.

A BSI APS-C EOS R camera is coming in the second half of 2022 [CR2]

I’ve learnt so much over the years from @Dalantech tutorials and blog as well as lots of great advice on other forums. I started macro in the film era and gave up as I just couldn’t afford it. Also the slow feedback didn’t make learning easy. So when I tried again a few years ago the superb advice from many really got me hooked. When forums work well they are a wonderful resource.

As for your gallery, I have really enjoyed looking through, particularly your bird shots. The mono heron is superb.
Happy to help! When I first got into macro there were very few resources, but a few people took the time to help me and the tutorials and blog are my way of paying it forward.

Announced!

I guess that they don't see the R6 as having enough resolution, when you project 2 images to the 36x24 sensor. I didn't bother to check the image circle, but I would ass-u-me that it's a full circle for each "eye" so that would bring us down to - at the most - two 18mm circular images. If it's two perfect 18mm diameter circles, you'd use 58.9% of the image sensor so 26.5Mpixels in total or 13.25Mpixels/image path for the 45Mpixel R5.
That is almost 4k per side, which is a nice marketing checkbox to tick.

SIGMA to start producing RF mount lenses in 2021

New title, "Sigma wont be producing any RF lenses in 2021, maybe never", and the other third party companies have stopped in 2021, because Canon and their legal teams put an end to it. They don't want any competition for its overpriced lenses, especially outside the US where prices are sky high, and third-party lenses would have lots more appeal!

Canon is offering very expensive L-series glass for a lot more money than before, or entry level budget lenses, many of which are a stop darker than their predecessors, for higher prices. The justification that the R5 and R6 can handle higher ISO is a moot point because these aren't the cameras that people would use budget lenses on...

Hang on to your EF lenses people, and buy an adapter, they work perfectly fine on the RF platform.

and also don't buy an R5 or R6 if they are suffering from lock up.

Circle In R5

Looks like the Spot Metering area. Check your metering modes and try some others, such as Evaluative, and see if you like that better. Spot Metering is good in some situations, tricky in others, especially if you aren't used to it. I like Spot for portraits, Evaluative for landscapes.

Have fun!
Thanks/ it was partial metering. spot circle is smaller

Problem with the EVF of the Canon EOS R5

Taking a photo of the electronic viewfinder with a smartphone is pointless in my opinion, because its lens (which is usually a wide-angle lens) is not free from distortion, and you will never be able to get a perfectly flat image of this electronic viewfinder. In the case of the optical viewfinder, it is clearly different.

I tried to take a photo of the electronic viewfinder of my EOS R with my smartphone (iPhone 7 Plus), and I also registered the image distortion. The camera was perfectly level, and on my smartphone I used the ProCamera application with the Tiltmeter turned on perfectly level. I took the photo "from hand":



If the EVF image is recorded directly with an external video recorder, no distortion can be seen.

Great point about distortion caused by using a smartphone to photograph and EVF! No way we can tell what's happening with the image posted. Thank you for chiming in!

Maybe, just maybe, OP and friends got a batch of counterfeits. ;)

Or...Could eyeglasses be causing perceived distortion, which is then "confirmed" by a smartphone shot?

The anomalies should be reported lickety-split to Canon!

Tweaking the EVF of the R5/R6 using Picture Style Editor

I was disappointed by the EVF of my R until I altered the picture style in camera. I set the User Def 1 style to set sharpness to the second lowest settings and contrast to the lowest setting. The difference was noticeable and I'm much happier. I don't use DPP, and don't notice any impact on RAW processing in LR.
