Red announced a 6K Komodo with (manual) RF lens mount today.

I've never noticed a whine on my Canon R5 charger or the one from my Canon 80D (same charger).

LOL I've still got my motor drive F1.

You mean by their own employees? Wouldn't today's tracking make it easy to see where the package disappeared, to narrow down the suspects to a very small number?

How much does one of those cost?

Click to expand...

It depends on the configuration. "Fugaku" is the $US1.2B flagship machine at RIKEN, which has ~160,000 nodes.
Their two-node FX700 rack server costs about $US40K (which you'll eventually be able to buy from Penguin Computing).

From the article it appears that Canon bought a single 650tflop FX1000 rack, which has 192 nodes.
So if you ballpark $20K per node then you're looking at ~$US3.8 million.

Given that Canon is the flagship commercial customer for FX1000, you can bet they didn't pay that much for it.
However they probably paid at least 1/3 again the purchase price for setup & maintenance services. Supercomputer clusters are not exactly turnkey commodity IT devices (although Fujitsu is angling to make the "little" FX700 pretty easy to get up & running).

To put things into perspective, for pure CPU compute (talking apples to apples, not GPUs here), a cluster of amd64 dual-EPYC 7742 traditional 1u servers crams about 280tflops into a similar rack, so Fujitsu's A64FX has almost 2.5x the compute density of the best amd64 CPUs you can get your hands on at the moment.

I used red, orange, and yellow filters with film. Maybe I had more than one strength of the yellow. Of course I had to make the filter decision before I shot the pictures.

I like shooting Raw and in effect choosing my color filters after the fact.

Its happening only at 1/8000 ...
shooting into direct sunlight is not ideal!

Thanks for that Info.
I suppose you‘re right with the sunlight. But of you don‘t recognize it now there seems to be no damage.
At least keep an eye on it.
But I‘d still call Canon to tell and ask them.

I would rather not add that much glass between my native lens and sensor. Introduces all sorts of potential issues around loss of resolution, weather sealing, stress points, size, weight, etc. I get the point that it can be done, but I would rather have a native longer focal length lens that is lighter and faster and then consider what extenders I want to put on it to enhance reach at the requisite loss of speed and resolution.

You miss the point. More MPIX lets you forgo the extra 100mm FL from the 300 to 400 f/2.8. No need for extra glass.

If you also get the extenders to supplement your high MPIX camera with the 300mm f/2.8 you are far ahead in options compared to shooting with a lower MPIX camera and a 400mm lens - and with more money in your pocket to boot!

It was just a good example that came to my mind to illustrate the point. Of course it is understandable why the term is used.

But similarly, with television meaning something like vision over a distance and telecommunications meaning something like communicating over a distance, I really don't see any issue in the fact that Tele-photo has become a term used to mean something that allows photographing things in the distance, despite having a scientific definition that sais something else.

Click to expand...

I agree with you. The technical definition of a telephoto lens is one whose physical length is shorter than its optical length. But, the intuitive meaning based on our common experience with language is a lens that is used to see far off objects or at a distance - the classical Greek "tele" means "far off", or "at a distance". Languages evolve to become simplified so the largest number understand words. I hate jargon and far prefer words or phrases that clearly describe matters.

I have a older 2X II TC for my EF lenses. It seldom gets used. I did not upgrade it to the version III on purpose, it stacks with my 1.4X TC III while the newer version will not stack. I've only used them stacked to play with the AF capabilities of my R. I might see what happens with AF on my R5 out of curiosity. I doubt if the end photo would be better than cropping but I might see more details as I'm composing. In any event, its interesting to experiment. I'm not expecting to get a RF extender in the near future. I haven't even tried my 100-400 with a 1.4X extender on my R5 yet. I expect it to work just as Alan has shown.

Click to expand...

The stacked 1.4x2xTCs should work. As I have posted previously, a 3x Kenco TC, which was sold for only manual use with DSLRs, focusses well on my 100-400mm II and R5. I really am impressed with what Canon has done with the R5 AF.

Not a local shop within a thousand miles. I won't randomly pick one of the few still standing. Sad but true.

I dig into the “pro camera” a little bit. That is what I have found: Nikon SP ( copied and improved Contax, out of production after WW II) is the first “pro camera” claim by the manufacturer. When Nikon F( first SLR from Nikon) came out, it inheritated the “pro” title. Both cameras are well built and have more features then their peer. After that every major Japanese SLR maker introduces a “pro” model to grab the market share.

Looks like you were trying to get to Midtown or Buckhead in a hurry. Great shots! I hope everyone was driving safely.

Click to expand...

Thanks! Yes, for the most part. I would prefer it be safer next time. Also hoping to slow the camera down even more next time as I'll have an R5 and 15-35 both with stablization.

Maybe Canon will come out with an RF lens cap something like the EF 40mm f/2.8 STM. But there are probably a lot of other things higher on the priority list.

I echo your comments about DxO PL. I can belt through processing with it. So far, I find DPP the best of what I have access to. It and Adobe will have to do until DxO releases the update, which appears to be slated for this month. By the way, the horizontal wheel on the back right alters iso on my R5 without pressing any button.

Click to expand...

Yup - mine too. When I'm in Fv mode I have to use the back mode dial to move between ISO, Tv, and Av, ad the front dial to adjust the values..

I live to leave the Fv selection on the shutter speed and use my left pinky to adjust ISO if necessary to get the exposure I want - it's fast than moving the mode dial back and forth.

I should just shoot full manual and use each dial for it's purpose but for some reason I've gotten hung up on using Fv.

Sorry for the "durst".
I was just translating a letter from a Swiss friend at that time, and, as the French saying goes, "mixing up my pedals"...

Linguists call it code switching. You're speaking in one language and without realize it start talking in the other in the middle of a sentence.

Think Tamron and Sigma are maybe considering to try to find out the differences between the Z mount and RF mount and make a base common design and add in the differences (Control Ring of the RF lens ?) and the reverse engineer the AF too.

Absolute zero hopes from this firm that it will start supporting high core count AMD CPUs or add better support for AMD GPUs. Also that dreaded subscription model will be getting even worse.

I'm glad you finally got that subscription issue off your chest. How'd you keep quiet about it for so long?

(Sorry couldn't resist, still waiting for my R5 to ship)

Close but i think the evf hump will be a bit bigger

I got the R6 and ive no af-issues with my:
35/1.4 Art
105/1.4 Art
70-200/2.8 Sports

With every lens attached the R6 shows me the green H+ in the vf/ screen.
But max speed feels slower then every test with native RF-glass on youtube :/

I’d be also be extremely interested in this lens; I absolutely love my RF 24-70 2.8, but it pulls my arms off it’s so heavy. Some of my studio shoots can be 10hrs plus and fantastic the 2.8 version is I don’t always need to shoot that wide open.

I did look at the new 24-105 super lightweight and ok as a holiday snapper but I don’t think I would use it for much else other than for light weight travel kit.

Please Canon make the f4 come in at sub 500g if you can and spare our arms

Ive used my RF24-105mm f4L IS USM for quite a few studio shoots now and was really surprised the first time I used it how good it was. Rent one and try yourself.

I am verrrrrry interested in this:
User interchangeable RF mount for Cinema EOS cameras

Any more information on this? Is that saying you could put an RF-Mount on something like the C300 III or C500 II - it definitely seems like you could, and that would be HUGE, because then you could use the speedbooster on those cameras and, especially for the C300 III, get a full-frame look or use the new, amazing RF glass.

You need to assign it a function in the button settings menu, it has no function assigned by default.
