I can understand, since, apart from the odd Zeiss ZE, I only bought Canon lenses. It may be purely subjective, or plain silly, but I've never been fond of third-party lenses. Yet, I know, some Sigmas can be better (sharper!) than their Canon L counterparts (Sigma 135 vs. EF 135 f2). Knowing this, I bought the Canon 135 without any regrets, and love it!
Anyway, what is "better"? There's more to a lens than just sharpness, just take a look at the wonderful EF 1,2/85...

Further development is always good for the competition. There are lenses where I want absolute sharpness like my RF100 Macro, but only for macros. When I shoot portraits with it, I like to use the SA control to blur the image a touch (one of five steps). No model ever wanted to see all the details. A good focus motor is important to me. I‘ve had the RF85 f2 STM and the STM motor just couldn't keep up - (That didn't work at all, I sold it and replaced it with the RF100) - The overall package simply has to be right. For the (especially used) price of the 17-40 you just can't go wrong.

Thanks, I didn’t know the RF 70-200 lenses were different that way. I never seriously considered the f/4 version to replace my EF 2.8 II.

Only the 4.0 is different. Agree to the EF 2.8 II. Mine is not for sale too, because of different use cases. Happy to own both

Rub it well with a lens tissue soaked in isopropyl, or even use a hand sanitiser gel ! You'll get rid of it and it won't come back if you keep using the lens.

Many thanks for the advice, I'll give it a go

I hope this thing is behind us next year. I check the local cases is our County about once a week. We lag much of the country because we are isolated by 300 miles from Seattle and a lot further to much population in all other directions. Lower population density delayed the appearance of Omicron here by almost a month. It is dropping off quickly in the last week or 10 days.

Yes indeed, we all hope Covid is behind us, but it seems extremely unlikely.

It's fair enough, IMO, that the richer nations vaccinate their own tax-payers first - after all, the primary role of any government is to protect its own people.

But in poorer countries, vaccination levels are still very low (for a variety of reasons), and while that remains the case, new mutations will constantly arise.

We've been very lucky that Omicron has turned out to be less harmful than Delta, but it's quite possible that the next variant to sweep the world could be devastating.

If the Canon's can be engaged while the camera is active like the Z 400 f/2.8 TC then it will be very exciting. The older EF 200-400 f/4.0 TC and Nikon 180-400 have all kinds of warnings about not to engage the TC while you are focusing or VR/IS is active. The new lens lets you flick back and forward while shooting at peak action and that's what makes it even more exciting. Built in TC's seem to be how we make super tele lenses unique for mirrorless, or perhaps just to add some bulk to an otherwise long empty stem.

Mind you judging by the Canon market sales performance it would appear the vast majority of the market considers DPReview the irrelevance it is.

The US Patent and Trademark Office has granted patent 11,212,451 for a lens adapter that is effectively a dedicated adapter. The patent is not limited to Canon lenses, but was inspired by the Canon transition to RF from EF lenses, and particularly the potential desire for an unadapted look and feel on super-telephotos that avoids the risk of inadvertently decoupling the lens from the adapter.

The patent covers the particular feature of the latch that engages the adapter to the lens being "inoperable" when the lens and adapter are mounted on a camera body. The latch may be internal to the adapter, or if external, recessed, smooth or otherwise intentionally difficult to inadvertently actuate. There may be an interlock to prevent a normal latch from actuation which connected to a body.

The inventor is a patent attorney specializing in optics, who has a number of other camera patents to his name. "Like with most patents, my inventions are simply novel solutions to problems that I have encountered. In this case, I was resistant to buy a new $12,000 lens of an old format and have it forever mounted with an adapter that didn't feel like a proper solution. Since then, Canon has decided to release the RF 400 f2.8 alongside the EF 400 f2.8iii, so this invention may never be needed. But I imagined them producing the RF version with a dedicated detachable adapter that EF owners could easily remove, and this invention was intended to help solve that problem."

The invention is available for licensing.

Petapixel had an article about Nikon a couple of days ago. It notes that even though all the growth in the current market is in mirrorless, Canon's DSLR market share is growing. Apparently because they're stealing it from Nikon. The author speculates that Canon might release a new DSLR for this reason. (A consumer type camera, I assume.)

Click to expand...

Canon is going to be giving Japan many more KISSes I believe.

I wonder if your focus is changing from initial pre shot focus acquisition to the time you capture the image, likely do to a user error rather than a mechanical problem with the equipment. Are you using auto focus? Manual focus? Are you using back button for focus? My personal recommendation is to modify the shutter button so that it does not focus, only meter and shoot. Then use back button for auto focus. Or, maybe use manual focus by turning off the auto focus on the lens if possible. Whatever it is, my guess is the issue is not due to a mechanical problem - more a matter of studying and really learning the details of how the camera works in regards to focus. Good luck - let us know what you learn at camera shop.

Thank you!
The red light came unglamorously from the stop lights of a reversing Mercedes SL...
Not mine
Leica M 240 Summilux Asph. 1,4/35 at f1,4, 1/8th sec. handheld (it was just luck, I was there at the right moment.)

Oh, the issues are VERY real.. But, after the sixth (!) update to 1.5 mine finally works. So if you’re having issues you can go back to 1.4, or go back and forth until it works. And yes, 1.5 is a lot better. With electronic shutter I have very close to 100% hit rate with for example a cyclist coming straight at me. It’s also better at erratic movements now. And the body detect when face/eye isn’t visible is a very, very nice upgrade.

Are we going to conflate equivalent and equivalence now?

Thanks on your report. Was thinking about it more in the mean time, and I think I will go for Canon 35mm f2 IS, since I'd be using Sigma at 35mm the most anyway.

With Canon 35mm f2 IS I get - full Canon AF compatibility, both on Crop and FF and great IS.
On Sigma I'd get more range, 1/3 brighter lens and slightly sharper images. But much heavier, more expensive, no IS, no FF compatibility, with a hope that AF will be always accurate.

could it be this canon camera patent that surfaced in 2020?

This image is more like this one

As an added note, the type of Fluorite Glass that Canon (and others!) use for their lenses tends to have a refractive index of about 1.43 with about 90% light transmission (plus or minus 1-to-2%) AND low-dispersion while Optical grade Acrylic is typically 1.49 with a transmissibility of over 92%.

Canon ALSO TENDS to use very high end coatings to reduce glare, reflections and to cut off IR (Infrared) and UV (Ultraviolet) bands which can create chromatic aberrations even if the lens element itself is perfect ground to high-precision concavity/convexity measurements for proper and/or the desired refraction paths.

With acrylic, the polymer nature of it allows for specific chemistries AND grinding/pressing to specific measurements that allow for ULTRA-HIGH-PRECISION light path management which ensure almost no chromatic aberration, no coma, no spherical aberration, no distortion, no astigmatism, etc. When properly "doped" with proprietary additives, it ALSO HAS a low co-efficient of expansion versus other polymers such as Polycarbonate so we can KEEP those precision calculated light paths perfect throughout the day and night in any temperature and weather.

In terms of light-gathering ability, the REASON we can offer a T1.0 lens is because we simulate using advanced ray-tracing techniques and simulation of the molecular-chemistry-based characteristics of light absorption within a polymer lens. This means we use a supercomputer to simulate on a grid from 65,536 pixels by 65,536 pixels imposed on EVERY lens element in our lens designs what individual beams of monochromatic Red, Green, Blue, IR and UV light do when traveling through a lens assembly from front to back and then on towards the imaging chip of the camera itself.

We answer the question of which pixel coordinates on each grid does each beam of light pass through on the path down the entire lens barrel. We examine and simulate HOW light scatters, refracts, diffracts and converges on every single grid point to ensure OPTIMAL light path management under a wide range of operating temperatures ranges and wide range of all-weather and non-optimal atmospheric conditions!

This lets us create a FULLY-AUTOMATED MANUFACTURING SYSTEM that has ultra-precision measurements and premium tolerances ensuring that each light beam from corner-to-corner for each lens we build ends up on the desired pixel of each imager chip we build and install in each camera.

The light gathering power for each frequency and amplitude of RGB/IR/UV light ray through each pixel-grid-coordinate can be FULLY MODELLED and corrected-for via precision grinding, stamping, polishing steps and via hardware-and-software-based RGB value auto-correction.

Since we can build a 50mm to 1200 mm Super-zoom at T1.7 to T4.8, it means the flexibility and pure light-gathering power is UNMATCHED in the lens making industry. AND we can do it at a price point that is ALSO UNMATCHED because the molecular chemistry and manufacturing steps required for polymer lenses is MUCH FASTER than trying to grow fused glass lens elements or grinding and polishing high-end glass lens elements to specific measurements! We can high-pressure STAMP-OUT a pre-shaped Acrylic Lens Blank in mere seconds and then micro-grind and super-polish lens elements using FAST mechanical and chemical systems in mere minutes rather than hours and days!

We have ALSO MUCH SIMPLIFIED lens barrel construction using MUCH OLDER prime and zoom lens designs but updating them for modern ruggedized all-weather usage. In this case, we have found that the older, now-patent-free German and Japanese lens designs TRULY ARE THE BEST MEANS to get a PREMIUM QUALITY still photo and cinematography/videography prime and zoom lens! Vastly simplified but very rugged motor designs, much simplified older but ruggedized lens stabilization systems and much-beefier-and-more-rugged lens-locking mechanisms let us give you PREMIUM LENSES WITHOUT THE EXTREMELY HIGH Zeiss Master Prime or Leica Summilux-C Prime price points!

We have no problem giving substantial credit and accolades to the MASTER LENS DESIGNERS OF OLD FROM GERMANY AND JAPAN who truly made CLASSIC LENSES that just worked and worked forever with very few issues. We have dedicated ourselves to BRINGING BACK those classic workhorse lens designs of old BUT UPDATING THEM for modern usage patterns!

Our modernized lenses are bigger lenses than an average Canon, Zeiss or Leica lens BUT they sure are much more ruggedized and able to go ANYWHERE IN ANY WEATHER !!!

Using an analogy, we are giving you a huge V8 engine in a Ford F450 Superduty Heavy Duty Truck body that's big, bulky and rugged BUT it also pulls 35,000 lbs so it means MUCH LIKE THAT SORT OF BIG ENGINED TRUCK, we just happen pull a LOT of modern super-sharp and colour-neutral optical power out of an older but beefier set of classic prime and zoom lens designs!

I appreciate all the good people, I really do.

The nonsense has continued throughout the day, and I've had to delete some stuff on this thread from new sign-ups and all of that. So I'm going to lock the thread up.

I will be spending the weekend getting Ethan up to speed on the backend, he will be one of the new writers during the transition. I will be providing them with information that comes to me for the coming weeks or months until the sale of the site is finalized. These things take time. I am confident that the new owner will have more time than I do to improve the site and continue the great community you all seem to have built here.

The moderators here have always had full autonomy, and that won't change.

CR Pro memberships won't be affected in any way. New signups from December will get their software code on February 18, 2022. I will be emailing all of those people this week with the information.

Maybe last night was a "meltdown", and that's fine. If you look, I'm sure the screenshots are out there. Folks should consider that perhaps I know things that they don't, sort of like future cameras and lenses. What's done is done and I can't take it back.

Onward and upward.

Thanks.
Craig

Interesting that they also say: "As for the size of the market in 2021, although it shrank by 200 thousand units, due to the insufficient supply of products by each company, it was still 5.4 million units." So confirming they are about 50% of the total.

In 2020, they dominated with 47.9% market shares worldwide:

Looks like Canon is growing stronger... albeit in a shrinking market.

Dear Unfocused. Thank you for such a sweet note. I appreciate your participation a lot too. I am here to stay! A bully is a bully because of having been bullied.

Just been looking at your site. Really impressive work. I look forward to seeing more of it.

Neuro for the win!! You are absolutely right! Now I will have to play around with this feature.

It's possibly next on my list for some reach beyond my RF 70-200 (the 600 STM was returned, I can see how it's good for some shooters but if I'm going that long, I'd like something which works in less abundant light servo situations)This 100-400 lens gets glowing reviews all round. Might have to rent it or just get it, it's quite the bargain and wasn't upped with the latest MAP increase.

I can't yet find a good combo for the fox on matte

Click to expand...

Yes, I can understand that image with its large deep black areas is harder to print well on matte paper - and you might still not like the result because of the different black inks used.. In the review I posted before Cooper wrote "The softness of the paper works well with this shot, since the intense blacks I’ve seen with it printed on a glossy paper are just a bit too deep for my liking" - yet someone else could prefer the deeper blacks.
I have to admit that among the photos I took in a recent trip of mine to Doha, I printed many daylight ones on the Fine Art Smooth (and I really like the color and details it can deliver, being a matte paper), but preferred a semi-gloss paper for some nightscapes.

Photo Bunny said:

I feel almost like I need to bump up the colours a wee bit for it to print well.

Click to expand...

That may depend on the difference between the screen(s) and the printer. Are you monitors calibrated? Using profiling tools can help a lot to reduce the number of test prints you might need - soft proofing (both in Capture one and Print and Layout) can be useful as long as screen and paper profiles are good enough. Test prints can be still needed, but i can become faster and less time and material consuming to obtain the desired print (repaying the tool as well) - anyway some skills and experience are still needed, a fully automated workflow is not available yet. There's a lot to learn.

Is there some resource with some basic rules/guidelines to follow?

Click to expand...

I learn it reading "Real world image sharpening" (Bruce Fraser and Jeff Schewe), the authors were among the firsts to advocate the three stages sharpening workflow PrivateByDesign mentioned above. But that book is very Photoshop/Lightroom centric, and also now refers to old versions, although the concepts are still valid.

Move on. There's the C70 or Canon C200 (going for cheaper nowadays) to upgrade.

To steer between the Scylla of too many and the Charybdis of too few requires either following Odysseus and tying yourself to the mast and ignoring the song of the sirens or, like his crew, stuffing your ears with beeswax.

I think I would like this as my A/B switch cam with my R3 as I like to take a lot of stills and can just get a rain cover for it (I'm sure it must suffocate the fan a bit but I don't fancy to be out in the rain anyway). Both don't overheat and both great video and stills. Oh correction here in southern hemisphere the R3 absolutely does overheat in the sub tropical summer whilst doing 120p filming in the sun after about 12 mins actually. The next time i take it in the pool to flim the dragonfly i need to keep it shaded as well as the direct sun melts it. Back on topic though maybe i can save for a year and get this.

I really want the normal R5 but plan to do interviews however.... If I do 25p raw or 10 bit at 4k with latest firmware updates would this be a problem anybody know? Hmmm but then again I'm trying to get into golf photos and video and 120p 10bit might be nice and R5c won't let me down if I'm getting paid but tadahhhhhh R3 and R5 will let me down. Okay so maybe R5c then because if I do sports video HFR would be nice without melting in the summer sun and stop shooting.

I do wish the Canon flashes had optical triggers though. When I used mixed flash systems Canon PCB and Profoto, I have to use the Canon's as 'masters' because they are the only ones I can't trigger optically.

You can stick a Sonia Green into the PC sync terminal on your Canon flashes to make them optical slaves. Might be useful for fills when using your B1's. Have to use manual flash, else the ETTL preflash will prematurely trigger them.
