If it was back in the day, it would've been 6x6. Today? Probably 1/2.3.

I wish there was a way for manufactures to share their lens correction data properly.

Possible an open source file format?

This way Lightroom etc. can benefit from the exact correction data to use in their lens profiles. Also, this would work in other ways. It would allow third party lens manufacturers to give their lens correction data to Canon, Nikon, etc. for use with in camera correction.

It was a nice little gem of a tiny 35mm SLR already with TTL! My first real SLR was a Nikon FM-2, I still have it...

On my MX, I replaced the standard (horrible!) focusing screen with a full-matte one, I adapted from an LX model.
It was indeed a little jewel, ultra-compact, but still usable with large hands. Despite using Leicaflexes and Leica Rs, I almost ordered a Pentax LX...
I also had Olympus' OM 1 & OM 2, with their focusing, aperture and shutter speed controls all aligned. I never got used to this strange disposition of controls, on an otherwise fantastic camera.
But the MX, I still regret having sold it!

Here’s me in 1973 with my first SLR – Canon FTb.

Currently, my hair is considerably shorter on the sides and almost nonexistent on top. Paisley (shirt) prints must have gone in and out of style five times since then.

Wow! In 1973 I was still playing in sandboxes... I got my first own camera about 10 years later, an already vintage Kodak Retina IIIc from mid 1950s w/o any manual I inherited from a passed-away uncle. So I had to find out how this camera works the hard way (fortunately, studying physics helped me with the basics of camera optics). Still have it, got it CLAd some years ago.

The 2024 EOS R1 and 2024 R5 Mark II do not include the mechanical "Sensor Shift" mode found in the original R5. Instead they use In-Camera Upscaling driven by a neural network. @zardoz is correct that these are different technologies. Sensor shift captures nine separate frames to record real optical data which is better for macro and landscape details. AI upscaling uses math to guess what the extra pixels should look like. This can create "artifacts" or fake details that were not in the original scene. For users who need the most accurate data for large prints the older 2020 R5 method is technically superior to AI guessing.

Digital correction in lenses like the RF 35mm f/1.4L VCM affects image quality. To fix barrel distortion the camera software stretches the pixels in the corners. This ruins the uniform noise pattern of the sensor. As zardoz noted stretching the noise can create a "lattice" or grid pattern. Furthermore many RF lenses have heavy vignetting. If the camera boosts a dark corner by two stops a photo shot at ISO 12,800 will have the noise level of ISO 51,200 in the corners. This makes it harder for the R1 or R5 II to clean up the image compared to using "optically straight" lenses like my 2008 EF 200mm f/2L IS USM.

The VCM in new RF lenses is designed for fast silent video focus. However this motor takes up space that could be used for larger glass elements. This is why some new lenses rely on software to fix distortion instead of using better glass. Lenses like the Sigma 35mm f/1.4 DG DN Art use a traditional optical design that is physically corrected. For still photographers this means the Sigma or older 2015 EF 35mm f/1.4L II USM may provide a cleaner raw file with less digital "stretching" than the VCM version.

My "Big White" EF lenses like the 2011 EF 400mm f/2.8L IS II and 1999 EF 500mm f/4L IS do not suffer from these digital correction issues. They were built with large glass elements that correct distortion and light falloff physically. When you mount these on the EOS R1 or R5 II you get a uniform noise pattern across the whole frame. On the 2022 EOS R7 the smaller APS-C sensor crops out the corners anyway so you never see the vignetting or stretching. This confirms @DocInfoSci’s point that older EF glass often provides a more consistent "raw" image than newer software-dependent RF lenses.

5Div/1DXii are for replacements for the rusted-on optical viewfinder/long battery life users. Film cameras are still being sold.....

If you mean new, recently produced film cameras, Canon is out of this business since decades, even Nikon discontinued their last film SLR, the professional F6, finally in 2020. There are only very few makers of new film cameras left, besides Lomo and these low-fi makers, Pentax revived the half 35mm film format with their fancy 17. This is a horribly overpriced underspeced plastic thingy for naive young hipsters that has only two positive aspects: it is a good training for classic zone focusing, since its simple viewfinder doesn't support focusing, and it brings users to think first and then hit the button (like in the old film days). I had the opportunity to use one Pentax 17 past year, and I immediately hated it. It would be okay if this this camera would be offered for 50 $, but nearly 500 US-$? That's crazy, but obviously there is a Zeitgeist market that Pentax has spotted.

Is it larger than FF?

@neuroanatomist confirms that Canon’s #1 global market share is based on actual unit sales. While Sony has previously claimed the top spot using camera revenue they remain #2 in total volume. In the Full Frame Mirrorless market Sony leads worldwide with approximately 44% share. Canon follows in second place with 31% and Nikon holds third with 17%. These companies dominate the professional market while brands like Panasonic and Leica make up the remaining small percentage.

I have a personal interest in the Medium Format digital market and discovered that Fujifilm is the clear leader. They own about 65% of the market because their GFX system is more affordable than competitors. Hasselblad holds roughly 22% of the share and the rest belongs to niche brands like Leica and Phase One. This segment is much smaller than full frame but generates high revenue per camera sold.

As @John Wilde and @justaCanonuser noted DSLRs still have a presence despite the shift to mirrorless. CIPA data shows 690,000 DSLRs were shipped in 2025 which is a 31% drop from the year before. Most of these sales come from Canon’s entry-level models like the 2000D. @David - Sydney correctly points out that these remain popular in developing countries because they are cheaper than mirrorless options. Been living in the Philippines for a few decades and I was told locally that dSLR bodies/lenses are not being imported here anymore for the past few years. I know because I made inquiries about the 5D Mark IV, 1D X Mark III in 2020 and even that 2000D this month for a picker friend. My personal guess is that developed markets like the US & EU where the mindshare among consumers is "dSLR" and not mirrorless so they reflexively ask for "dSLR" even when the whole market is moving to MILCs. However for professionals and those interested in "full frame or bigger" the market has moved almost entirely to mirrorless bodies like the R5 Mark II or the Sony A7 series.

neuroanatomist and @P-visie mentioned Pentax but their sales are insignificant in the global share for full frame or medium format. While @Del Paso calls them boutique cameras they do not compete with the "Big Three" in unit volume. For those tracking the top of the market the competition is strictly between Sony, Canon, and Nikon for full frame, and Fujifilm for medium format.

I'm not sure this is the kind of retro camera people were expecting from Canon, but it surely is interesting

Weird is the appropriate word for it!
I guess with the "right" influencers Canon could sell thousands of it.

Hi @Richard CR
I was wondering, why there isn’t a news to the new Nikon Z 70-200 II 2.8 .

I remember R6 mkii is the best selling in 2024 in usa so Sony didn't say anything after 2024.
If R6 mkii is still sellling in 2025, I don't think A7V help a lot.

First time I'm sincerely sorry for not taking a macro lens in my backpack! Carpenter bees (Xylocopa sonorina) are very common on Hawaii. The problem is that one will always see black ones (females)! This is my second, may be third encounter of a male (23+ years!!!). This one was on a sidewalk and I moved it to nearby stone (males are not stinging - females will if handled!!!). Not very active - maybe dying... Last shot was handhold: the tripod became more an obstacle than a help.

For me the surprise today came from the insects... Birds were the commons.

But you've chosen a corner with pretty much no detail. Can you show a bottom one? Assuming it's not too dark and some detail is indeed visible

Click to expand...

I chose a corner with no details because the point being made was that the noise characteristic was problematic and not 'uniform and consistent', and an area of the image lacking detail is the best place to see noise artifacts, if there are any to be seen.

But sure, here's the lower left corner of the image, with some people standing/sitting around. Including at least one person staring at their phone and completely ignoring the lighted fountain sprays set to the music of Prince.

Does anyone have any update on first shipment. Feb 24th was the rumored ship date that BH and others suggested, now it is TBD?

Looks like B&H and Canon USA removed the ship date (previously Feb 24 as you say) from the product page for the 14/1.4. I placed my order with B&H within minutes of preorders opening, and my order page for the lens shows "Est. Delivery: Mar 11, 2026."

Where should I look, if I want to know the size is the image circle?

Click to expand...

The image circle size is not an officially published spec, at least not as far as I have seen. Some YouTube reviews will talk about it, generally in terms of how usable (or not) a given APS-C lens might be on a FF camera. Sometimes some zooms have FF or near-FF coverage for some fraction of their range, for example.

Agree but $6k doesn't really look a "mid price" to me (that's the Sigma 300-600 f4!). Around $4k would be more ok.

Click to expand...

Look, I'd love to have a 600mm at f/4 for $4k too while we're at it lol. But where we're actually at, the RF 70-200 f/2.8 Z is $3300, and a 300 f/2.8 (or 600 f/5.6) has some huge elements and length to add to the front of that type of package. It's probably gonna be at least twice as expensive.

We have an RF 100-300 f/2.8 L with the same front element size requirement as a 600mm f/5.6 and it's almost $11k. I (perhaps wishfully) think it makes more sense for Canon to have price differentiation vs. that for a new lens, so I'm optimistic it will be a good bit lower (also a 2x vs. a 3x zoom). But as of today, $11k is what actually exists in the RF lineup right now for the most similarly-sized RF lens to this hypothetical 300-600mm.
