The world’s largest digital camera for astronomy is complete. Once in place on a telescope in Chile, the LSST Camera will gather an unprecedented amount of data about our Universe, yielding new insights into everything from dark energy to asteroids.

For the tech-geeks:
[The sensor] is made up of 201 individual custom-designed CCD sensors, and it is so flat that its surface varies by no more than a tenth of the width of a human hair. The pixels themselves are only 0.01 mm (10 microns) wide. The front lens is over 1.5 meters (5 feet) across.
It'll capture from IR to UV light.

On March 29, 2024, Canon registered two new cameras for WiFi and Bluetooth approval with a government agency. This falls nicely into the late April – May announcements coming from Canon. The cameras registered carry the model codes DS126922 and DS126928. We reported about the registration of DS126922 back in early February. Canon DS126922 Canon

If photos recording terrorist attacks like this are rewarded, I believe it encourages future terrorism. Whether we support Israel or Palestine, I don't believe anyone of us want to have innocent people experience this or have last photos like this exposed to the world.

The rumor mill has once again become a ghost town, which tends to be fairly standard ahead of major Canon announcements. First up for Canon will be the NABShow in Las Vegas, which runs from April 13 – April 17. That show tends to be for the Cinema EOS line, though information about that has

In this patent application (2024-043295), Canon is concerned about the AF performance of fast tilt-shift lenses. It seems that the incidence angle of light hitting the pixel will cause issues with AF performance around the periphery – especially when the plane of focus is tilted. In machine-translated Canon patent speak, this is what Canon has

In this patent application (2024-043481), Canon looks to improve the molded glass aspherical lens resin. According to Canon, the resins usually have a more difficult time with high humidity, as the optical performance changes with humidity. But if they create a resin that resists high humidity, then it has a more difficult time bonding to

As title, wonders if the sensor is still draining battery or the shutter is closed sensor power down?

I have two peedlites:
580EX
600EX-RTii
I can operate both as master and slave.
How can i operate both using a transmitter/trigger?
Which transmitter do I need?
I am using R5

I had intended to use the RF 100-500mm for photoing insects close up because it focusses so much closer than the RF 200-800mm and it has much better magnification. RF 200-800mm mfd is at 800mm is a very long 3.2m, and the highest magnification is 0.25x at 200mm with an mfd of 0.8m. The RF 100-500mm has its mfd at 500mm of a very short 0.9m with magnification 0.33x. Yesterday, to my surprise I got my first butterfly shot of the year and it was with the RF 200-800mm at 673mm and very sharp. So, I tested both lenses close up with photos of a British £20 note. It has lots of areas of different degrees of colour shading and contrast, which are much more informative than monochrome charts. I did images at 3.5m, 2.4m and 2m.

Not something I would normally would need to use but now Im working on some fairly jumpy birds in southern Spain I think its a good occasion to set it up. I cannot find it on the Menu or the guide book.
Any suggestions ?

It’s been a slow month patent application-wise, unless, as I told Craig earlier, I start to talk about printer patent applications. No one wants to do that – including yours truly. In this patent application (JP2024-042622), Canon talks about some Ultra-wide full-frame zooms. Now, this is one area of Canon’s lens portfolio that is pretty

What's the current consensus on the question of turning off image stabilization when using a tripod?

I use an R6 mark 2 and will be doing some landscape photography with the RF 24-105 f/4 and the RF 70-200 f/2.8 which of course have their own stabilization systems that apparently work together with the body's IBIS.

Are the current IBIS stabilization systems smart enough to handle shooting on a tripod or should I switch it off?

If I do switch it off, does the switch on the lens do the whole job or do I need to go into the camera menus and turn it off there?

I'm sure some of my fellow Canon fanboys know the answer! Thanks in advance!

Is there a comprehensive chart somewhere that shows all the RF lenses (to date) IS ratings with and without IBIS on the R5 and R7?

I was pleasantly surprised with the way the reflected light was rendered by Helicon's Pyramid method.




I think it's funny how the steam fogging the lens was rendered. It could be fixed by a high noise global shutter photo?

In this patent application (2024-039230), Canon is looking at methods of cooling a hybrid speedlite capable of both continuous and flash lighting. As with most speedlites in the modern era, heat is the biggest problem facing speedlites. The flash tube that outputs the light usually runs quite hot; this heat must go somewhere. As we

I just got an R8. The camera has so many dial rings on the body that I'm not sure if the control ring is really worth the extra $70 on the two EF adapters, with vs without ring. I haven't used the one R lens I got with the camera enough to tell which adapter I should get for my EF lenses that I'm keeping. What do you use the control ring for and is it worth the extra on the adapter?

My European electronics engineering sources have recently told me about Canon Singapore sources showing off an internal document about the current iPhone sensor of 7.01 x 5.79 mm being replaced with a Canon or On Semiconductor manufactured RGB imager and lens-assembly. A set of 64 Megapixel one inch sensors is now being tested at Apple which are 13.2mm by 8.8mm (i.e. RGB Bayer-Patterned 1.3 microns per photosite) very-high-light-sensitivity imagers that are rumoured to rival even Sony Starvis image sensors in terms of low-light sensitivity. The KEY ISSUE is that Apple has been looking AWAY from Sony as its primary image sensor supplier via recent exploratory talks with On Semiconductor AND Canon being leaked to external 3rd parties!

My European Engineering Sources have told me that Apple and Sony have been having a recent technology and price disagreement about high-light-sensitivity Sony RGB image sensors not being made available at the price points Apple is looking for. Exploratory talks with BOTH On Semiconductor AND Canon have indicated a willingness to supply large and very light-sensitive RGB image sensors for super-smartphones at a minimum of 64 Megapixels (i.e. 9216 by 6912 pixels) in resolution.

A research and development contract was seen by an external 3rd party which indicated that Canon and On Semiconductor are both willing to supply such high light-sensitivity imagers to Apple at the price points needed. The current in-house rumor has Canon having the current technology/production lead over On Semiconductor due to an obvious and documented difference in the reduction of luminance and chroma noise between the Canon-supplied and On-supplied 64 megapixel one-inch-sized test image sensors during low-light conditions. Basically, it was found the Canon sensors looked much nicer on RGB output at pre-and-post sunset and sunrise light levels and during night-time street lighting photography scenarios in both still photo and video recording sessions. The new sensor offerings will be for an upcoming series of higher-end iPhone models. The exploratory talks with both image sensor suppliers were rumoured to have taken place in May 2023 with test sensors from both companies being shipped to Apple by December 2023.

I suspect Apple is trying to show Sony that it isn't kidding around and is VERY WILLING to change suppliers if it doesn't play ball with supplying low-light sensors at a good price point to Apple. Apple is large enough that even Sony is not immune to being put on notice for providing Apple a better price point or more technology-leading sub-systems!

I should also note that an American-based LIDAR/IR emitter supplier was ALSO INCLUDED in this exploratory set of talks which indicates Apple is likely going ahead with the long-rumoured high-resolution 3D-XYZ scanner that will be included in future iPad and iPhone systems used to support live 3D-XYZ object and 3D-Environment scanning during still photo and video recording sessions to be used as datasets for the Apple Vision Pro AR/VR glasses systems now available and for those future AR/VR glasses versions in current development by Apple.

This LIDAR/IR scanner is a ALSO part and parcel of the long-held-rumour that Apple is exploring the world of designing and building super-fast metal powder deposition 3D printers and super-fast plastic resin 3D printers as an entirely new product category for Apple where it has the fastest multi-head 3D printers along with the most durable and tough metal and plastic resin 3D printing "inks" around! You need really good high-resolution RGB imaging and 3D scanning for that and this rumour starts to look more and more like a very coherent internal product plan that is very forward thinking for Apple! I actually can't wait to see an Apple plastic and metal 3D printer --- After personally sampling what the Apple Vision Pro can do for AR/VR, I can DEFINITELY SEE the potential of ultra-high-quality Canon or On RGB image sensors within Apple iPhones/iPads being used for 3D-Scanning and super-fast 3D-printing!
