Canon EOS R5 Firmware v1.5.2

Could we suspect a few electronic componants changes due to worldwide shortages, explaining differences between R5 production series about freezing ?
FW 1.4 never caused any freeze on my R5, but some people seem to have had this issue on some R5 with FW1.4 too... Strange.
We know that CFe cards can be a problem, but many photographers didn't change anything betweend FW versions and saw freezes appear however...

CANON SOLAR PANEL FLASH BATTERY CHARGERS?

There are solar panel chargers for AA batteries on the market, having one with a flash compatible connector isn't a big deal.

Question is how useful is this application of solar charger. The more sun light there is to charge the batteries, the less likely you are to use the flash.

well you charge the batteries when its sunny for use indoor or for niteclub work etc..

R5 Grip extension

Will we see third party battery grips for the R5?
I have no idea but for me the issue is simply having a grip extension that allows the little finger to contribute, for comfort and ease of holding larger lenses. Without this particular grip my little finger curls under the grip and it is quite apparent just how much that finger contributes to grip support in general - it is very helpful. There are quite a few logistical issues when one examines the challenge of a non-battery grip such as battery access and stability of the camera when it is laid down on a counter. We need some creative thinkers attacking this issue. I'm still happier with this particular extension than without.

Canon R1 - At 80MP - Would You Buy It?

I'd like to ask a question, to a very specific group of photographers, I hope this does not offend anyone.

To answer this question, you must be a professional Sports Photographer who has shot sports with a D6 or 1DX or 1DXII or III AND to supplement your income at times you shoot within other genres. But at least 75% of your income should come from sports

QUESTION:

If the Canon R1 allowed you to shoot in a range of 6MP to 80MP based on your creative needs would you consider the latitude in resolution, positive?
YES or NO

If the Canon R1 allowed you to shoot in a range of 6MP to 80MP would you use it for Sports and other Genres?
YES or NO

If the Canon R1 allowed you to shoot in a range of 6MP to 80MP would two CFExpress card slots complement your workflow?
YES or NO

If the Canon R1 allowed you to shoot in a range of 6MP to 80MP at 16fps RAW and 20fps JPEG would the enhanced resolution still benefit your business/studio/you
YES or NO

If the Canon R1 allowed you to shoot in a range of 6MP to 80MP would you be able to market your sports photography to a wider audience for larger format work like in-store displays, bus wraps, car wraps, billboards, outdoor banners, digital out of home displays, venue walls?
YES or NO

Do you currently earn above $500.00 per photograph used at sporting events to include Olympic, Professional, Extreme and College Level Sports?
YES or NO

Based on your total Sports Revenue what group would you consider yourself in as an individual or the sports agency you work for?
A. Less Than $50,000 USD B. Between $50,000 and $200,000 USD C. Between $200,000 and $500,000 C. Between $500,000 and $1,000,000
D. Between $1M and 2M USD E. $2M to $5M F. Above $5M to include gross revenue from all your photographers on staff.
1.) Yes though it's not negative, 2.) Yes, 3.) Yes, 4.) No, 5.) Wrong question. Greater MP allows for greater flexibility & isolation of the "subject" within sports images, 6.) per single image... No, 7.) Individual & B

  Laowa 12mm f/2.8 Zero-D for EF: question for astrophotography

Hello. I own a Canon R5 with several lenses including the 8-15mm EF fisheye and the 15-35 f2,8 RF which I use mostly for astrophotography (Milky Way and Northern light).
I just came across the latest Laowa 12mm f2,8 BUT I am not sure if can somehow fit between the EF Canon fisheye which I already own and the 15-35mm RF lens specifically for those kind of pictures that I am interested to taken.... (Ideally a brighter f 1,8 or f2.0 maximum would be better).

Any comment?

Canon Speedlite Transmitters

Actually, I believe you need the ST-E2 optical trigger as the ST-E3-RT does not have an optical trigger according to Canon. You can use the 600 RT in optical mode.
Thanks for the correction. Somehow I missed the 580EX in there, which cannot be radio triggered.

For the OP, another option is to use one of the flashes on-camera and the other off-camera, since both can be masters. Another alternative would be the little Speedlite 90EX. Not a powerful flash on it's own, but it can serve as an optical master on-camera.

Canon Patent Application for Drone Camera Gimbal

While I agree with much of what you mention, I don't think it is beyond Canon to compete with DJI if they decided they had to. Do I think they will, successfully? Well, my guess is probably not, but it wouldn't surprise me if they did. And it's a shame, since that's where soooo much money will be spent in filling a new market with massive sales expectations.

I don't *need* a drone today. If so, then I'd bite the bullet and get DJI. I can wait a couple years to see if anyone else gets in the market with a viable enough product.
Drones tend to be a cutting edge high-tech market, where products are packed with all the latest features for the price, that's something that Sony tends to do as that's their point of difference from Canon. Consumers buy the drones with the best video quality and flight times available for their budget, and that's why DJI is where it is. Some companies don't withhold technology intentionally like Canon does, and try to pack in the highest tech specs for the money, and therefore attract a lot of tech gear enthusiasts for that reason. Canon is not one of those companies...

MULTIPLE CANON BODY REGISTRATIONS

Hoping we get some new version of a RP like body or something in that price range that offer IBIS like the Z5.
It's about time Canon came up with an update for the very first RF cameras, the EOS R and RP. Those just re-used sensors from previous DSLRs anyway, which kind of makes them 'half-new', and it would be nice to see some new camera bodies at the entry and mid level.

C70 firmware Update adds 4K and 1080p Cinema RAW Light recording

Jesus, no need to be so damn rude. It’s not fake, the C70 outputs to HDMI whatever your recording settings are. It even says so in the updated manual. Don’t believe me? Contact canon yourself instead of calling other people liars.

There is a problem for Atomos owners, however. I contacted Atomos and was told initially that they’d be able to record RAW from the C70 to the Ninja V+, but was then contacted by another member of their support team who apologized and said that they’d need to release a firmware update before they can record Canon RAW LT or SD coming from the C70.

I imagine it’s because the Ninja isn’t familiar with that particular “RAW” codec.

Canon Applies for 135mm f/2 Patent

Someone did the simulation and all kinds of aberations are low enough.
If you need help reading the rayfan charts: https://www.handprint.com/ASTRO/ae4.html
View attachment 202811
maximum scale is 20μm
Thanks for sharing. I cannot read out from the graphics that these really are from that new Canon design, but I'll believe you, that this is not from any other lens ;)
Sharing the source would be nice next time.

Shoulder strap for EF 70-200 f/2.8 L IS USM II (LZ1326)

A quick search at B&H (I'm sure Adorama offers similarly):

Lots of good options are various price points. I'd recommend something with the metal clasps at the end. If you're looking to be thrifty, consider searching eBay for a lightly used option.

APS-C DSLR

The M series sells more cameras than an apsc ever could or would. The consumers that purchase the M series cameras dont give a hoot about the EOS R camera ecosystem and would simply purchase what already exist. Canon knows this and will continue to sell its new M series cameras that are only but a couple of years old.

I wasn’t saying that I thought they would discontinue the current EOS-M cameras, I was predicting that we wouldn’t see any new models….

Canon Patent Application: Shutter that minimizes shutter shock

Shutter shock seems to be a phenomenon that arrived with more robust vertical plane shutters. One of the biggest culprits was the original Nikon FM from 1979, an incredibly popular camera concept, but the early adoption of the Copal vertical plane metal shutter caused the whole camera to jump when the shutter fired. In retrospect I realise it caused me many sharpness issues. The situation was improved with the FM2. I think this was why at the time the professional 35mm cameras continued to use the horizontal curtain shutters despite the fact that it gave a slower flash sync speed, but shutter shock more almost non existent, and I realise now, decades too late, why I generally got sharper images with my Nikon F3 than I did with the original FM.
So the phenomenon isn’t just to do with mirrorless, but i haven’t heard of specifically IBIS making it worse.
I notice shutter shock-like effects in the 1/60-1/200s range, which I strongly suspect is more an effect of the way Canon programs there ILIS/IBIS systems than it is an effect of mechanical resonance. But that's only with fully mechanical shutter, which is a mode I virtually never use, since I don't have EF/RF lenses faster than f/1.8.

My M6II is another story, that only has a fully mechanical shutter and not a well dampened one, you can feel the camera jumping when holding it loosely. Luckily my most used lens on that is the EF-M 32mm f/1.4, which has no IS that Canon programmed to make things worse :)

R5 Firmware 1.5.2 is out

Confusion has arisen because you have repeated another thread which started when the update was posted only on the Malaysian Canon site, before the Japanese one etc https://www.canonrumors.com/forum/threads/canon-eos-r5-firmware-v1-5-2.41339/ and there are now two parallel threads With near identical titles.
By sheer minutes, so I imagine it was posted as I was writing mine and with Japan being an hour ahead of Malaysia the firmware was likely released here first. I don’t think there’s any confusion, though. At the time I made my post the firmware had not yet been released on the canon us site. It was still the 16th. Two threads? Oh my, the horror!
