Chris Frost's review of RF 100mm Macro.

I will buy one soon or later. I need the higher mag and like the SA control. Chris Frost mentioned the shift would be small at macro distance (5:40) and it won't be "terrible an issue" ( free quoted @7:20).

At the moment I use a Sigma 105 macro and the RF100 will be probably better.
If I would own a EF 100, I maybe won't buy one.
Do yourself a favor and buy the EF lens! The focus shift is more severe than you think. I own both lenses and can assure you that it is a bad lens...

R5 silicon cover and battery grip

I myself have not found the heat issue ? Maybe its the colder climate
I don't have it either, I just take stills and not at high speeds. However, overheating is easily reproducible if you push the camera to record high data rates to the CF Express card over a period of time. Just doing stills is not an issue, its high rate video that generates the heat faster than it can dissipate. If the camera is insulated, heat escapes much more slowly, so that may change .

R5 w/ RF24-70 f2.8 has IBIS wobble @ 24mm?

I But I’m confused because people say the RF15-35 has wobble when it’s at 15, you have to zoom in a little bit to get rid if it. But the 24-70 already zoomed in more than 15.
Presumably the issue is occurring at the wide end of the zoom range for that lens, not at some specific focal length(s).

Naïve question, is this only with video? I don’t notice anything odd with my R3 and RF 14-35/4, but I don’t shoot video on ILCs.

Hesitating on this R5 Purchase..

[..]I guess I have two questions for you all. After all the recent firmware updates on the R5, how long do your R5 cameras last before overheating in 4K HQ? Can you still capture stills when they do overheat, or is the camera rendered useless until it cools down?[..]
Still capture is completely unaffected by video (over)heating. During summer I tried to film dragonflies at 120fps (complete failure, not due to gear) and got the overheat warning, switching to stills let me do 20fps photos till I overheated myself and had to find some shade :)

Has the Canon EF 100mm f/2.8 Macro USM Lens been discontinued?

Thanks for the replies all, yes I’ve looked at MPB and their used lenses. Although, I am inclined to buy a new one as I do not plan to buy another one in the foreseeable future. This lens will be ideal for my dental photography.

Does anyone know if this lens will come back in stock or a new version released soon?

Thanks

I don't think the lens has been manufactured for a while and it looks like they've sold off the remaining stock given the number of weeks it has been out of stock at most places. I doubt they will be making more given the new RF macro options.

Refurbished lenses are occasionally available on the Canon USA web site - the last one was a week ago. This is likely as close to new as you will get. You might set up a notifcation on Canon Price Watch if you want to go that route. https://www.cpricewatch.com/product/00003/Canon-EF-100mm-f2.8-Macro-USM-price.html

If you are shooting with an R series body, you might consider the RF 85mm F2 Macros IS STM since it is a bit cheaper. It is only 1:2 reproduction. You'll need to use the EF or RF 100L if you want 1:1.

Canon EOS R6 firmwave v1.5.0 changelog posted, download now available

Have been off forum since last April when I gave up on the R5 due to consistently missed shots (small birds in trees, brush). It was on 1.3.0 - I had to revert from 1.3.1 which was much worse. I was headed to the Galapagos last September, and couldn't afford to miss most of my shots with the flakey R5, so I benched it. I'm still plowing through over 12,000 photos taken with an OM-D E-M1X and an M1 Mk III, and I don't regret the decision to go OM-D one bit.

Back to the R5: on 5 December I installed 1.5.0 on the camera, and updated the RF 100-500 to 1.1.0 at the same time, then took over 500 shots of small birds wintering in my yard over Christmas and New Years. The AF felt like it had improved over 1.3.0 (hard to be sure after not touching the R5 for 8 months), but it is still locking on the background past the bird enough to annoy me. That forces me to fight to bring it back with the manual focus ring - it still won't reliably re-focus automatically - which usually means missing the shot completely. I had a particularly bad 80-shot session with two Golden-crowned Kinglets in my post oak trees (no leaves, sun behind me) where it repeatedly locked past the birds, and eventually crashed the camera while I was trying to re-focus. The error message was unreadable (ran off the LCD to the right) and it required the usual switch off and remove the battery pack actions to revive it. Only five shots were keepers, while 65 were out of focus to varying degrees and 10 were blown by bird movement (1/500 or 1/640 at f7.1, Aperture priority and Auto-ISO).

I have to agree with many of the others posting on this thread, that even 1.5.0 has not resolved some of the AF issues on the R5. It gets wonderful images when it gets it right, but it fails to focus correctly far too often - much worse than my old 7D Mk II with EF 100-400 + 1.4, or either of my OM-D E-M1s. I hope Canon did a better job on the R3, but I don't think I'll be the one to find that out.
What did Canon say about the issue ?

Canon R3 does not show 6k RAW or 4k HQ in the menu!!!

On of the reviewers on youtube (Gordon, I think) mentioned that the 6k resolution is under the '4k' icon.

Do you have your camera set to HDR mode? That locks out a number of things and isn't actually related to HDR video.

This is correct: there is no "6K" icon. 6K resolution is under one of the 4K icons, as you have indicated. You will know it is 6K because the resolution will show as 6000x3164, despite having selected the 4K icon.

R6 bluetooth issue

I use bluetooth in my R6 and R to connect to Canon Camera Connect on my Android phone and to the Canon bluetooth remote. With the R bluetooth function setting I have disable/enable, smartphone and remote. With the R6 I simply have enable and disable. If I wish to switch between phone and remote, I have to unpair, then pair, which is a pain as this is not necessary with the R, where I can simply select phone or remote.
Am I missing something?

Up to 6 month delay for R3

Whats the latest order date where someone has received an R3 so far?
Probably depends from where. For B&H, preorders opened at 6a on launch day, a member reported ordering at 8:45a and getting one, another reported ordering at 10a and not getting one. AFAIK, there has been only one shipment to the US. Canon USA had them in stock briefly the morning of release day, presumably from cancelled preorders.

G7X Mark 3 turn on grid and level?

Since this thread has been revived I will update my experience. I looked at getting an M50 for my travel camera, and took another brief look at the Sony option. I decided to get the G5X II. I still wanted something that would fit in my jacket or pants pocket, and I still prioritized lens speed over long focal length. The G7X III seems to have been aimed more at vlogging, which I don’t do. The pop-up viewfinder of the new 5 is a welcome addition for shooting in bright sunlight. It is not clear enough to use for focusing, but fine for choosing composition. The diopter adjustment is too fussy, so it can take several tries to get it close enough to use. Besides having a little longer zoom (but still a fast lens), the new 5 seems to have a bit better lens otherwise.

I left for Italy in October, 2019, traveled around for over a couple weeks, and then went on a 14-night Mediterranean cruise that came back to other towns in Italy. I threw the G7X II into my bag as a backup, and wound up using it by chance on my first day in Rome, given my sleep-deprived and jet-lagged brain. It did fine, of course. After that I took over 3.000 pictures with the G5X II. I never missed having any longer focal length, and I was happy to be shooting at f/1.8 to 2.8 in dark interiors. I had some great shots of Venice by night as we sailed out, so handheld in the dark from a moving ship. One of the shots is displayed in homes in three states now.

And outdoors in the sun, I was glad to have the viewfinder.

Canon has registered two unreleased lenses with certification agencies

It has modern electronics, which virtually always emit RF. The certification is there to ensure the emissions outside the product are low enough and/or outside protected bands (e.g. GPS, GSM, etc).

I don't know if the USM motors need hi-speed signals to drive them, but the EF pins have a relatively high frequency protocol going over them.
Agree that lenses need electronic certification. @[email protected] stated that there aren’t new lenses being registered.

Sometimes rumor sites even get ahead of themselves and wrongly assume that because it's a product number and not a lens name, it's a new lens. That doesn't appear to be the case here.

The fact that these are new SKUs suggests they are, in fact, new lenses.

Industry News: Nikon announces the NIKKOR Z 28-75mm f/2.8 and development of the NIKKOR Z 800mm f/6.3 VR S

...... I went with RF instead of Nikon or Sony based on the gut feeling that over the next couple decades Canon would catch up.

My one solid fear is that Canon's lead in sales is so comprehensive, and so well-managed despite not having the best gear, that they may just get used to having good sales without being cutting edge.
Yes, this is the only real issue - Canon are a comparatively conservative company. They'd probably *claim* that their philosophy is to let other companies do the beta-testing, (and then only introduce things in Canon gear when they were satisfied they had the best and most reliable implementation), but the R5 overheating issues rather exploded that myth.

More likely is that Canon's sales success just leads them to sit on their laurels and appear complacent. The frustrating consequence for their customers is that we need a lot of patience as we wait for them to play catch-up, with new bodies and lenses. It's pretty much the opposite philosophy to Sony, who rush their latest technology out as fast as they can and thereby capture the early adopter techno-enthusiast market. Poor old Nikon meanwhile try very hard to produce class-leading cameras (and often succeed, ref D810, D850, Z9), but sadly have great difficulty convincing people to actually buy their products.

I'll probably stay with Canon for 2 reasons, a) the cost of switching is too prohibitive, and b) I prefer Canon ergonomics. But if I was rich enough to be able to afford to switch systems, I'd be very tempted by the Sony a1 and it's vast range of native glass. I'd rate Nikon and Canon about the same as far as lenses are concerned - Nikon have some lenses that I prefer to Canon nearest-equivalents, but likewise Canon score with others such as the RF 100-500mm. I'm very impressed by the specs and design of the Z9 (and the price!), but I don't like gripped bodies, so that kicks both the Z9 and the R3 into touch. Looks like I'll be staying with the R5 for another couple of years then.

Darktable now supports Canon’s CR3 in v3.8.0, which is available now

Figuring out how it was done doesn't get you out of the patent/copyright jungle.
Copyright in code is the same as it is in text. If it isn't extremely similar the it isn't copying. Just because what it does is similar is not the same as it's code being the same. Clean room implementations of code are done all the time and are accepted even in the US. That just leaves us with the pesky patents.

Some one posted the big list of video patents a few months ago trying to make the case that software patents were enforceable all over the world because there were patents related to video codecs all over the world. I took a dive on the patents that applied to the country I live in and every single one of them applied to using the codec is conjunction with a specific hardware device often players if one form or another,. Not one of them was a software patent.
