New Big White Lenses from Canon are Coming in Late Q4 and Possibly a 500mm Prime

Even as the third-party companies favored by aquatic mammals are attempting to increase quality, they are also increasing prices closer to Canon, Nikon and that other company.I'd suggest that you start comparing Canon, Sony and Nikon price lists.
Sorry, but similar products are usually priced similarly.
Are you sure the RF 100 macro with SAC and X 1,4 wasn't the "never seen before macro lens"?Longish macro zoom… 200mm range?
The never before seen macro lens rumoured last year hasn’t appeared yet.
One of that (many) cases when the common name is the same for two or more different species. This is the American White Admiral (Limenites arthemis). The Eurasian White Admiral (Limenites camilla) is different looking on upper and the undersides.After a futile hummingbird photo session (they went to the neighbor's feeder for their portraits), I was bringing equipment in and noticed two different butterflies on our Eastern Nine Bark.
They say the best camera is the one you have on you, so I used the R5 and EF 600mm f/4 III + 1.4tc. It felt like I was using a bazooka to shoot them!

To be announced less than 6 months after the ufo "Disclosure" movie?“new and unseen technology”
The never-seen-before primes predicted for 2026 will be big whites with TCs.
The never-seen-before zoom predicted for 2026 will be.......(?)
Merci beaucoup!Thanks a lot! Even I understood your explanation.
You demonstrated the the French proverb: "Ce qui se concoit bien, s'enonce clairement".
OK for the malt!
Thanks a lot! Even I understood your explanation.Resolution is the ability to separate two parallel lines next to each other or separate two dots next to each other. That's why when you read the charts for the resolution of a lens it's given as line pairs per mm (LP/mm) or line widths per picture height (LW/PH) or for printers dots per inch (dpi). It is a linear measurement - measurements along a line in units of length. Area depends on length squared, measured in square mm or square inches etc. The total number of pixels is measured by the number of pixels in an area, not along a line of distance. When you double the number of pixels in a sensor, say from 22 Mpx to 44 Mpx, you don't double the resolution, you increase it by the square root of 2, ie by 41%. To double the resolution, you would have to increase the number of pixels in the sensor 4x to 84 Mpx. The same is true if you double the number of pixels in an image by doubling the focal length of a lens - although you increase the number of pixels by 4x, the distance between two parallel lines or two adjacent points is increased by only a factor of 2, the square root of the number of pixels. So, resolution varies as the square root of the number in an image.
That's now two beers or glasses of peaty malt whisky you owe me. It will soon be worth my while driving to Alsace to claim them.
Clearly, the advantage of the MFT 2x crop factor comes into play if you crop all, or most of your images, as is the case with me. Obviously you understand that if you crop a FF image from the R5 II - or any FF camera - to the size of the MFT image or smaller, than the OM-1's 20 MP sensor totally out-resolves any and all Canon and Nikon FF cameras, and is about the same as the R7. If you have used both the OM 150-400 and the Canon 200-800, then any comparison is a joke. Basically a top-level pro lens with a very good consumer lens. The OM lens is definitely better, in my opinion, than the excellent Rf 100-500, too. The AF subject detection and tracking is definitely on par with the original Canon R5, R6 II, and better than the R7, all of which I have used. Pre-capture is better than any Canon, FPS options are higher, and the stacked sensor has a very fast read-out speed. OM's IBIS is still as good as anything on the market. It is true that OM Systems is basically a niche company now, which is unfortunate. It is difficult, in a world where the internet influencers essentially dominate the marketing opinion of consumers, for them to compete, since we all "know" how FF is the only way to go if you are a "real" photographer.

So, could you please elaborate why "it's not the number of pixels on the subject that counts, but the square root of the number", as I don't understand the distinction.![]()
I am definitely neither a scientist, nor a mathematician, since I studied literature. So, could you please elaborate why "it's not the number of pixels on the subject that counts, but the square root of the number", as I don't understand the distinction.It's not the number of pixels on the subject that counts for resolution, it's the square root of the number. My speciality is shooting small birds in the wild, and I've posted thousands of images of them over the years on Canonrumors. And why shouldn't I compare it with the 45 Mpx R5/R5ii - it's what I shoot with. And for years before that the 50 Mpx 5DSR. I crop all the time, and it's the high resolution sensors that let me do so.
