Sigma officially launches the RF 18-50mm f/2.8 DC DN Contemporary

Isn't it for the manufacturers to say if it is reasonable or not and not for us to guess? Unless you have done specific inside knowledge?
and you have answered your own question as the camera manufacturers have determined what is reasonable and they haven't provided any weather resistance measurements except for one OEM and only for one model.

Fisheye Photos that are not Full Frame

I’ve had this lens for quite a while. I prefer the diagonal versus circular view for photography but imagine there are some specialized uses for circular. The challenge really is finding the right subjects, when the distortion adds something to the image rather than becomes a distraction, like lying down on a path in the forest and shooting straight up. I may have posted some images in theads a while back if you want to do a search.

I picked it up early in my APS-C days where it could function as a diagonal fisheye at 8mm and it worked just as well on my FF bodies now. It is similarly useful for APS-H cameras at 12mm and FF at 15. I figured this was part of the reason they did the zoom in addition to the EF 15mm fisheye. I have a Samyang 8 mm for my APS-C EOS M bodies.

The EF 11-24 overlapped usage somewhat, with the 11mm field of view is similar to a defished 15mm image. I believe I posted a comparison of that in a past thread, https://www.canonrumors.com/forum/threads/canon-ef-11-24mm-f-4l-usm.24975/page-7#post-527161. I still use it when I am looking for a distinct viewpoint.

All-in-One card reader for CF Express B + SD + MicroSD?

I built a PC with floppy drive sized StarTech USB 3.0 multi-card Reader with UHS-ll Support, but have to use an external ProGrade CFExpress B/SD USB C reader for CFExpress cards. While StarTech slot will read Micro SD cards I find it less fiddley to just shove the Micro cards into an adapter then into either reader.

Canon’s 2024 Roadmap, and the timeline surprised us [CR3]

The Alps are beautiful everywhere :cool:
I mostly wander the Italian side of them and there are so many enchanting places
The Dolomiti are very different from the Swiss and Austrian Alps in structure and vegetation, but also quite beautiful. I truly enjoyed the trip from Lienz to Bolzano.

Canon has registered a memory card reader with USB and Bluetooth capabilities

We've reached the point where it could be a combo SD Express/CF Express reader, running on USB 4.0 and packing Bluetooth, which is something that a lot of enthusiasts and pros would want for field usage. Despite the lack of SDE-equipped cameras and general hardware over the past several years, the controllers have now been available long enough for products (cameras, camcorders, and readers) to be developed and SDE can easily slide in and replace UHS SDXC cards in the ecosystem, while maintaining full backwards compatibility.

Interesting Lens Setup Coming from GoPro

I got this tasty tidbit from a U.S.-based secret camera sales person source who indicated that GoPro is making a special version of their Action Cams that have a REMOVEABLE LENS that will have a small form factor quick-locking mount.

The current Gopro 12 Hero is a 12 mm to 39 mm lens system at f/2.5 that uses software trickery to get that sort of variable zooming.

The newest Gopro Interchangeable Lens Action Camera will be sold alongside the original Gopro Hero and will have a different naming convention.

There will be FOUR compact lenses available upon introduction that will have a very reduced fish-eye effect in the final imagery coming closer to traditional fixed focal length wide-angle imaging. These lenses will be a 14 mm, a 28 mm, a 38 mm (38 mm?) and a 50 mm prime-like lens that are extremely compact but do not the fit current GoPro enclosures which are being revised to fit and will be sold alongside the original enclosures.

The new pop-on/pop-off interchangeable lens mounting system will be made available to 3rd party manufacturer accessory-makers.

The reasoning behind this new GoPro interchangeable lens system is to facilitate less fish-eye distortion for specific sports and action scenarios so that a more narrow-focused final image can be realized as per numerous requests from Hollywood crash-cam and stunt camera operators, plus requests from TWO unnamed major sports leagues (one is rumoured to be FIFA and the other is American Baseball!) who want to experiment with putting wireless body cameras onto players and on-field officials. Gopro itself was specifically requested to provide such a type of interchangeable lens action camera!

My source also says there were numerous feature requests sent to GoPro over the last 10 years who is just now responding to such a marketplace request from end-users.

This type of announcement is just one more cascading effect of new product innovations that is starting to affect Canon's marketshare. What will Canon do to offer something in the Action Camera Segment?

Nikon officially announces the Nikkor Z 35mm f/1.4 at $599

On what body are you using the Tamron? I have been thinking about either getting the RF35L to replace my STM version or getting a fast 35 to use alongside it, and the Tamron 35 1.4 might fit the bill. Would appreciate any inpug you would be willing to share :D
I suggest you look at the Sigma 40 f1.4 Art (yes, a hint longer then 35mm, but definitely non quite a 50mm), it's a masterpiece, and cost nothing, 750€ brand new; I have it and it's probably the sharpest lens I've ever had. Just have to deal with size and weight, but you get a lot back for you sacrifice.
If you want something really 35mm and smaller and lighter, the Sigma 35 f1.4 Art cost almost nothing today, 300/350€ used, is as good as the Tamron, and works flawlessly with all R bodies, it also has full in-camera corrections like a first party lens (vignette and distortion but not the DLO which is for Canon lenses only), as Canon allowed that on the EF mount for the Sigma art's, and the ability is retained by R bodies, while Tamron's (but never had a recent one, so please check my statement) I think they have not the "first party" treatment for the in-camera corrections.

We need a new pancake RF 40 mm 2.8!

1. The Nikon 40mm is not a true pancake lens.
2. The Canon 28mm is superb. I can't recommend it enough.
3. The 50mm + 28mm combination feels really cool on the Canon R8. The old 40mm pancake was too close to 50mm, but 28mm + 50mm is a great combo. This way, you cover street photography, environmental portraiture, and general portraiture. You even get decent background separation with the 50mm f/1.8, and it has a very sharp center, allowing you to crop up to 70mm easily. Nikon doesn't have lightweight 50f1.8; even Chineese third-party lenses like Viltrox are big and heavy.

Can Canon Compete ?

the original question is will Canon make a competitive lens to the nikon 800mm 6.3 neither the 1-500 mm or the 2-800mm are NOT competitive

How do you define "competitive"? If we're talking about weight, the RF 800mm 11 is far superior to the Nikon 800mm 6.3... but obviously nobody would actually claim that. In what ways do you find the Nikon 800 to be superior? Just the aperture?

To answer your question, I do doubt that Canon will release a direct competitor to that Nikon lens specifically in the price range. If size/weight isn't an issue, the EF 800mm 5.6L is going on ebay for about the same price as the Nikon (unless I am getting my lens confused).

Canon Patent Application: Canon RF 28-70mm F2.8

I still don't understand how you are going to take a picture of something wide enough to require 24mm with a 35mm lens, no matter what your preference is. Unless you have a preference for shooting parts of a building, rather than the whole? It is not always possible to move further away. If you don't take those type of photos then no problem.

Canon Patent Application: Small Primes for Compact APS-C and Full Frame

That doesn't make a huge amount of sense to me. Lens designs for about the 20-50mm range (in terms of 24x36mm sensors) are much simpler when they don't have to leave a lot of room for the flipping mirror. The natural way to design these lenses results in rear elements closer to the sensor than the mirror would allow. (Past 20mm the lens design starts getting complicated again no matter what you do.)

But the EF-M lenses ARE mirrorless designs, with very short film-to-flange distances. They can't be used on cameras with mirrors, unlike EF-S, right? So an EF-M has basically all the design freedom an RF-S does.

If it is legitimately lighter and cheaper and not suffering in some other way (bigger, less sturdy, slower AF, more aberrations, worse OOF bokeh, etc.), that'd be real news. The only things I can think of are that RF lenses no longer have to care about vignetting or distortion, since these can be undetectably*** fixed digitally. It's possible that new lenses are letting these two metrics slide into the wastecan, and using the resulting freedom to improve every other aspect of the lens (e.g., making it lighter AND cheaper AND higher resolution AND lower aberration AND better OOF highlights etc.).

The EF-M lens has 14 elements (including one Glass Molded Aspheric). The design in the patent has only seven elements and appears to have at least two and possibly three molded elements that may well be some kind of optical plastic. The back two are much more aggressively aspheric than traditional glass molded aspherics. That change in technology would account for my initial comment, "lighter and possibly cheaper, with excellent performance". The RF 28mm makes that case very effectively. Are electronic corrections being thrown into the mix as well? Possibly, but the 28 is pretty decent without that. Molded lenses are the way phones make cheap and quite good (for the size of the imager) cameras. Molded lenses are very cheap to manufacture once you have invested in the outrageously expensive mold (and Canon may well have developed a way to make the molds less expensively).

Expect more delays from Canon for both cameras and lenses

So you’re still unwilling to support your claims with any actual evidence. Manifestly, that’s because you are unable to do so. Your pathetic attempts at deflection are as sad as they are trite.

Let me remind you of the first sentence of your first post:

That is a statement I know to be unequivocally false. So right from the start, your blatant lie cost you the respect I typically afford someone by default.

My response was mildly condescending, “It's cute that you think a lack of real information will quell the whining in response to a 24 MP rumor.” Intentionally so, because I give what I get and you began with condescension (“You do realize that…”).

I also quoted a prior post of mine pointing out that I’m fully aware that not all information posted here is true (as should be obvious to anyone with a modicum of intelligence given the site name). You have yet to support your very first claim that nothing here is true (reposted Canon statements notwithstanding).

As for the rest of your diatribe, that’s as blatantly false as your initial claim. I certainly don’t think I’m better or more knowledgeable than everyone else. I do have experience in optics and business, both of which are relevant here. There are plenty of people in this world who I know are smarter than I am, including a few here on this forum…people who I respect greatly. However, you are not among them.

You obviously came here seeking to agitate, and when you got the reaction you were aiming for, you started tossing insults and playing the victim card. Reminds me of a certain recently convicted felon with hands best sized to shoot with an EOS M 100. Probably someone who inspires you.

Regardless, this ‘discussion’ has become pointless. Feel free to reply or not, you’re not worth any more of my time.
Lol, now you are walking back on your statements. ONLY one with information about Canon products is CANON!!!! It's just that simple. There is no inside informants, it's all a fake the supposed inside information here. This site was created as a gag site. But you have taken it to be way more than that and believe somehow they have inside or extra information when they don't.

R5 or wait for the R5 MkII - Stills only

They have nobody that prepaid so I will be stopping in this week to see if I may be able to persuade them to take my money if I decide on the Mk II.
I'd suggest just giving them your money now and decide later. If you decide you don't want the camera, it's certainly they'll have a buyer for it so there should be no risk for you. I use the same strategy with B&H, if I think I might want the announced item, I preorder it then think about it. If I decide against, I cancel the preorder.

The only time I didn't do that was with the RF 10-20/4, which I decided I did not want (I had the EF 11-24), then changed my mind well after launch when packing the 11-24 for a trip in January and having to shoehorn it in. Even though no major or local shops had it, with some Google searching and a few phone calls, in February I was able to find a small camera shop that actually had it in stock and I ordered it on the spot.

Canon LP-E6NH multi battery charger?

I own several dual chargers for LP-E6 NH batteries. The thing that is lacking on most is the ability to monitor the battery temperature. Most chargers that I have found, single or dual, have only two pins which connect to the battery. They are missing the 3rd and 4th pins which are the com pin and the temperature pin (which is the important one). The exceptions, that I have found, are the original Canon charger (single only) and the Nitecore UCN1 (single) and UCN2 Pro (dual) chargers.

The problem with the Nitecore UCN2 Pro dual charger that I have is that it very often will not indicate that the charging is finished, even after 24 hours. Of course, I don't know if it is still charging, but therein lies the problem...I don't know if it is still charging after 24 hours. Other times, with the same exact batteries, it will charge quickly and indicate that the charging is finished. I just don't trust it. It will report battery temperature while charging though.

The charger that I am currently using is the isdt LP2 Air charger. It doesn't have the T or C pins, so it doesn't monitor temperature. But, it does connect via Bluetooth to your smartphone via an app and it provides a running total of mAh, running charge time, voltage, charging amperage, and battery resistance. It will charge in turbo mode, but I have never used that as it will charge two batteries in less than 2 hours.

I have not tried it with an original Canon battery as I don't have one any longer. Some people report that it has problems with Canon batteries, others say no problem at all.

With my Patona and Newell batteries, I can 100% recommend it.

If the Nitecore would work reliably, it would be my favorite. But, I don't trust it at all.

Opinion: Rumors and Websites

The tone of your articles is always “Here’s what MIGHT be coming…and here’s WHY we think so”. To me, the “grain of salt” is plainly implied. But rationality and logic often don’t work on the internet.

Given that I am happy with my R5 as it is and the lenses I have, for me this is all idle curiosity, but I find it amusing to watch people passionately argue about things that may or may not even exist. I fully expect that when the facts about the R1 and R5II are finally known, forums will be FULL of people admitting they were wrong and apologizing. (Just in case you need these: /S /S /S).

Sigma: No plans to release RF full-frame lenses yet

Hopefully my R5 will last until the R5iii comes out... it still has 1 year of warranty left of the Canon Australia 5 year warranty period.

Even if it fails, I will get another R5 second hand to fit my underwater housing as I imagine the R5ii won't align with the controls. It will be expensive change when a new body and associated housing are bought together. Current R5 housing is USD1700 for my Ikelite system but "Pros" use Nauticam which are USD4800 just for the housing. The other bits can be reused though.

My L glass should last a lot longer although migrating from EF to RF lenses has been a pleasant (if expensive) experience. I am sure that the buyers of my used EF lenses are still happy with them.
In the second half of the 2000s, digital ILC developed fast, but after about 2012 (for Canon) were really good cameras available for photography - video still progressed quickly (driven by Sony after Canon's groundbreaking 5D2 defining a whole new field of videography). I kept my 5D3 for nearly 10 years and traded it in for my 5D4 only because it had about 250.000 shutter actuations (still working flawlessly) and Canon offered a huge discount. The 5D4 was of course a better camera in many respects, but that was just an evolutionary step, not a disruptive anymore. I think, today it's the same with the video implementations in such multi purpose ILCs. It is so good even for dedicated videographers in actual ML cameras that you can use such a camera for many years again and get very good results. So, I think it is smart to omit at least one or two next generations of a certain camera and better invest the money in lens upgrades.

That said, I will keep my most used L glass lenses, too, I think, because they work so well on the EF-RF adapter. Plus, I sometimes prefer character over perfection of certain lenses, e.g. I like my EF 85mm f/1.2 with all its optical flaws. Technically, the RF version surely is a much better lens.
