Today's catch!

Only this from today! And for this one I was scolded: "you got so close to the bird!" - you scared it!!! Well, I was actually "zooming" back because the bird was coming closer and closer to me! That women passed in front of my lens and the bird was still there!!!
Some people are ignorant or just a morons?! Any way, only the bird from today...

No idea about the specific mushroom, but the overwhelming majority of mushrooms fall into the category of ‘edible but not tasty and will probably cause some GI discomfort’. A small number of mushrooms are in the ‘edible and tasty’ category, and an even smaller number are in the ‘deadly if ingested’ category.

The hen-of-the-woods falls into the large edible but not tasty group.

"A small number of mushrooms are in the ‘edible and tasty’ category, and an even smaller number are in the ‘deadly if ingested’ category."
I agree with that but what is "tasty" for some is kind of "mediocre" or "not tasty" for others!
In most cases it actually deepens on how you prepare it: you don't make chicken, pork, beef e.t.c the same way, no?
Grifola frondosa (aka "hen-of-the-woods") has a flavor similar of some Amanitas (yes! there are edible Amanitas like the most known A. rubescens and even the highly prized A. cesarea) and some other mushrooms (like Leucopaxillus giganteus that is by far more meaty!) with the similar flavor. You may like or dislike it but it's just a different flavor!
I could be an exception but for example I don't like the flavor of any Truffles! Or may be I just haven't tried some prepared by a good chef?!
And a case from Sweden: I went out to look for Boletus edulis but instead found +/- 2 pounds of Cantharellis cibarius. Met a family with two small children and when they saw my basked they were like "where did you find these? We are looking for these!!!"
I gave them my C. cibarius because I'm not realy fan of it.
For my big surprize they gave me their collection of B. edulis!!! I asked few times "are you sure?!!!" but they were so happy with the Cantharelle!
It was more Boletus than I was expecting to find and lately gave half to a friend!

This is the first time I've seen this mushroom. They're very pretty with their white stripes. Are they edible?

Click to expand...

I don't think the edibility is known but judging by some other features they should be in section Xanthodermatei. It means they should be +/- mildly to moderate toxic (as all others from that section of the genus). In the literature you may find that "some people can eat" specifically A. xanthodermus. I don't think it's about the person who eats it. I had an experience in Bulgaria when one of my colleagues came with a jar of marinated A. xanthodermus. She was insisting that "many people" of that place are collecting the mushrooms without ill effects. We (5-6 people) tried it and nothing happen (symptoms are coming rather fast with that kind of toxins). I think it's a case of where you are collecting such a mushrooms!
The bottom line: I wouldn't eat Agaricus of that section even in survival mode (huh - especially in that mode!)!!!!
And BTW that mushrooms were with metallic taste. No reason to collect them even if you know they are not toxic!

The M5 with the 22 was a great 2nd camera for me for a few years. It rarely gets a mention but I was impressed from the first look and feel. Even for larger hands it just worked.

Canons lazy, 'were not trying' direction with RFS is super unfortunate. My m5/m62 + 22f2 and 11-20 is still in service, and was hoping to replace them. both lenses simply DELIVER. So I agree with everything in this writeup. Somebody high up at canon really came to hate the M series, IMHO.

To this day I'm still amazed at the output from the 22f2 especially. The 22 is not super wide, but f2 flexibility, great build, and no hood needed. Superb iq. The 11-22 was used for my widescapes any chance i got. Too convinent, and 32p, sharp corners on the m62. Pure win.

The m1 served me well for years -I bought the m50 in 2019 and didn't like it much. But the build is phenomenal..compact, angular, solid. It went back in the box for 2 years. I bought the m62 to replace that (FOUR versions from canon refurb, 2 was DOA) , and learned about the shutter shock phenomenon that pretty much all reviewers skipped over. Totally random AF misses. And the bad internal battery issue, that the con tech told me they dont fix. The m50 came back otu of the box, and history was made .

That said, the s9 has otherwise ended my crop camera career. Don't need an evf, Im well trained on the original m1 bac screen only use case. It's small compared to the r5. It's fantastic.

I waiting for canon...and I'm glad thats over. Cheers to the EFM - good stuff.

I thought Canon's camera assembly was so robotic/automated that labor costs weren't an issue.

Meanwhile, Fujy sells a lot of compatcs with buttons and dials. And probably those looking again for compact cameras and using old models are not exactly looing for touch screens, Since a camera unlike a smartphone is designed for a single task, it's bette driven by a specific interface. Sure, the smartphone crowd has to learn something new - if this is a real barrier... mankind is doomed.

I just returned to Canon after 25+ years with EOS and a switch to Fuji for the past 4. I thought the switchback through carefully and slept on it for the past year.
Since I liked the Fuji color science, 40MP crop friendly + IBIS it really came down to ergonomics and my constant fight with the unintuitive menu system (BSNYC would kill me for that term). I was bumping dials and buttons left and right...it's a pretty crowded machine.
My macro suffered, there was too much to toy with and the subpar AF after being spoiled by Canon 3, 5 & 6 series bodies from the EOS 3 to the R6 was really the final straw.
I had no flow.

Canon in hand, flow returned

Contrasty fellows! I particularly like the congregation in the first photo.

Sure - it’s when missing data is guessed.

When reading in chemistry data like which genes were active in a cell in a tissue slice it’s common to have no value read. Could be for all sorts of reasons.

To get around that some people will fill in the blanks with (educated) guesses. It could be that many similar tissue slices are scanned and averages are made for each approximate cell location, or perhaps neighboring cells with values are used to determine what likely was going on.

But a guess is a guess, no matter how good. It’s still invented.

If everyone knows that and is appropriately cautious then all is well. If not, or the software using the data is unaware, then overall errors can be made. Not unlike the use or abuse of rounding, which is handy but can compound into an error.

Actually, I have to correct myself: the files from the R5 II do the same, but those from my original R6 do not.
Also, I updated Adobe Camera RAW today, and now it has profile for the 45mm, but I can still show the difference:


R5 II on the left, my original R6 on the right. Both photographs are corrected for vignetting and distortion.
Canon is including lens profiles in the RAW file now or, at least, Adobe is able to read that information for newer cameras.

Prior to this update, the photographs from my R6 with the 45mm had no correction at all on ACR, while with the other cameras they had since day one.

I much prefer this approach, since Adobe profiles tend to overcorrect.

Please explain the 2nd sentence. I do have a little background in molecular biology but the meaning escapes me.

I am looking forward to this rumoured sensor (if it turns out to be real). I have an R5 that’s kept up with all my demands. I earn a living shooting portraits, headshots, product, and interiors/boats. I have have a wildlife photography hobby.

For a secondary/backup body, the R7ii, with a prosumer (5/6 series) design would tick most of my boxes. For wildlife I’d have more pixels on subject. And, for everything else I control the light, so there’s no diminished signal in the S/N ratio. (I don’t often deliver files that need more than 20-24mp - it’s only a couple times a year a client actually needs high resolution).

I think I’d also like to see what I do with the alternative FOV provided by a crop body mounted to my FF lenses. For example, I have a big’ol Sigma art 85/1.4 that I use for headshots and portraits. I could see selling it and using my RF 50/1.2 on the rumoured R7ii, for something nearly the same. I don’t shoot the Sigma wide open - headshot need more DOF and I prefer a sharper portrait (most of the time).

This might also encourage me to upgrade my EF 16-35/4 to the RF 14-35/4, which I think would make a nice little, relatively light, and flexible walk around lens for an R7ii with a 5/6 series style body.

I just hope it has a very substantial buffer. My wildlife skills are not up to par and I lean heavily on a deep buffer to make up for my lack of timing…

(1) Effects are only applied to the JPEG file

The in-camera DLO function makes corrections in real time, but its effects are applied only onto JPEG files at the time of recording. To apply DLO to RAW files, you can either;

- Post-process your RAW files in-camera. You can apply DLO (if it wasn’t already enabled) or change the effect level, and the effects will be visible in the exported JPEG image.

- Use Canon’s free Digital Photo Professional (DPP) software to post-process your RAW files on the computer.

It does read the optimizer data and performs the adjustments. Third parties aren’t provided with instructions on how to parse the optimizer data and need to do their own math, which is often limited to apparent distortion, shading, etc. and less so the physics of the lens that Canon’s engineers have bothered to calculate.

(EDIT: no, the R5 II reads the same way, it's my original R6 that does not)

Anyway, it has been stated by Canon that optical corrections imply sacrifices as well. If I’m not mistaken, they have clearly mentioned that this approach allows them to create sharper lenses.

And people really ignore how much profile corrections EF lenses had. I’ve shared examples in this forum a few weeks ago. While distortions were usually more corrected optically, vignetting levels were very similar to those of RF lenses.

If you want to use Canon's Digital Lens Optimizer, then yes you need to take JPGs from the camera or use Canon's DPP for RAW conversions. But 3rd party RAW converters have profiles for RF lenses that require digital correction, and they work just fine. Personally, I view using Canon's DPP with the same affection that I view getting a Norovirus infection. I use DxO PhotoLab for RAW conversions, which is what I did for the aforementioned RF 14-35/4 vs. EF 11-24/4 comparison, though I also included camera JPGs along with DPP and Adobe RAW conversions for completeness.

It's not. I see no reason to use Canon's software to process Canon RAWs. DxO, Adobe, Affinity, CaptureOne, and a bunch of others seem to manage just fine (as they do with RAW files from Nikon, Sony, Fuji, etc.). IMO, DxO handles noise reduction much better than Canon's DPP, for example. No reason a software pipeline couldn't run demosaicing and image corrections if properly coded, just as 3rd party RAW converters do.

Click to expand...

Wait, are you saying that Canon’s digitally corrected lenses are already corrected in the raw file itself and digital optimizer isn’t needed? And therefore any third party editor gets the same benefit of Canon’s software corrections before their own third party corrections are applied? i.e., I could theoretically put the RF lens on a Nikon or Sony body with an adapter and get the same image for the same shooting situation like I could with an EF lens?

If so, then I guess the lens really is hardware plus soft box in a self-contained box.

But my impression is Canon’s magic is more like digital lens optimizer in reality.

I have yet to use DxO or Capture One.

Is the RF performance equal or better without correction? Or did Canon just try harder with the software? Not being facetious, I don’t know the answer and you might.

For personal work I’m OK with optional correction that I tend to do all the time anyhow. For lab image capture and processing by AI pipelines I’ll hope the labs stick with EF or third party for now.

So I’ll keep hitting the gym and lug around my EF beasts.

Canon's software correction requires a Canon pipeline -- right? Unless I'm mistaken, you can't take the raw image straight to Photoshop or Affinity photo and get Canon's special sauce applied; either the HEIF or JPEG needs the in-camera adjustment, or Digital Photo is needed for a raw adjustment combined with export to, say, TIFF — only then can I edit the image with the adjustment somewhere else.

If my understanding remains current, then I'd have to say Canon's solution is still pretty janky and unique to them among a sea of camera and lens options. I'd say that the original lens performance still matters if other software pipelines are desired -- say, for custom agentic LLM architectures ingesting images for medical or other scientific purpose. And there are many teams out there who can easily grab a camera and do advanced imaging plus analytics vs those who can afford to spend all of their research money on a big, dedicated box with 240v mains supply.

I think that's actually quite different from film. For film, one develops and then scans and then carries on like normal.

I think that in the context of Canon's current default-approach of software correction it's fine to call-out any such afflicted lens for awards. I mean, it is clear by now that Canon decided that a singular lens is a combination of its hardware + post-shot-enhancements. A lot of people here seem feel the same way, although I assume mostly due to an acceptance of lack of options for the Canon-supplied, in-production lens catalog.

I personally still prefer to evaluate everyone's lenses on their physical characteristics. I see the software-corrections / enhancements / visual-sugar to be an early-stage post-processing trick that, while surely convenient, is still a trick and not a lens.

That stated, I also use the R6's built-in digital optimizer for making better JPEGs for quick shares with family/friends. Or I use the digital optimizer in Digital Photo Professional for more serious work as a RAW-based refinement precursor to Adobe or Affinity edits. Edits are edits in that regard, especially when just accounting for light physics.

But there is something about that olympian goal of pure performance based on physics. High quality glass / plastic combinations within a price point should always been the community pressure on vendors, in my mind, and that alone is where I'd like to see the mount open up to competitors: to curb design laziness on Canon's part.
