panther fan: The good news is that C1 is so slow with adding features that it makes absolutely no difference if you are on a 3 or 4 generations old version

@cxsparc
You wouldn't have needed to update for those. They are just ICC profiles in the color profile folder. You could have downloaded the test version and copied the profiles into your old C1 version.

For me, they work great in C1 20

[Also I think they are called ProStandard]

For those who wants very large bodies with telelens there is now a more attractive alternative than Canon.

@Alam12
If you only need a 400mm F2.8 it's not clear at all the Nikon is the best.

If you only need a 600mm F4, it is almost 100% certain that a dedicated 600mm F4 will deliver better results

If you need both. The Nikon is without a doubt the best.

And as always, in the end, we will win with the Casoniko competition game. Sony introduced the sub 3kg superteles, with the close center of gravity. Canon followed. Now Nikon.
Nikon introduced the 200-400 F4, Canon followed. Canon introduced the 200-400 with integrated TC, Nikon followed. I am pretty sure we will see TCs in all next-gen superteles. After all the Canon/Sony lenses are already mid-replacement cycle again.

@photography-lover

The Z9 in combination should have been able to focus on the eye. Looks like a focus fail

derfotograf: This is a very specialized tool for a few photographers, similar to a 5-axis CNC milling machine for carpenters.

A solid tool for professionals who make a living from sports and wildlife photography. However, most photographers will rent it instead of buying it, meaning not too many units will be made.

For the rest of us, it just serves as an image carrier that documents Nikon's know how.

You are all underestimating amateurs. 14k$ is a lot, but comparable to many other hobby investments.

The amateurs will outbuy the professionals probably 9:1 on this lens.

Canon and Nikon published in the past that the vast majority of 1DX buyers are hobbyists. Fujis 10.000$ MF camera is bought 85% by hobbyists according to Fuji.

You overestimate the number of pros that need this lens and underestimate the number of hobby photographers with cash.

PWPhotography: Very nice! It combines a traditional 400/2.8 and a 600/4.0 into one lens. If there is more IQ loss than regular 600/4.0 with external TCs when internal 1.4x TC engaged?

@Thoughts R Us
Could be a great 400mm F2.8

But at 600mm it probably isn't competitive with dedicated 600mm lenses

Maybe worse the samples are not in focus. For example, image 3 doesn't have the focus on the eyes. That can happen during shooting. But why select that image for an international marketing campaign?

MikeRan: The annual upgrade costs have gotten out of hand. It used to cost $80 to upgrade every year.
I’m on C1-20 and probably will be forever.

My money went to DXO for Photolab this year.

@BrentSchumer
Should have gotten a test or beta version first. The HDR sadly has giant artifact problems

@BrentSchumer
Lenses need no C1 update. C1 can use RAW embedded profiles.

Also, most people are not updating their cameras that regularly. So every 4 years a software update for the new camera would be totally fine.

And if you are ok with some adjustments to your workflow you can use the most modern cameras in the oldest version of C1. Simply convert your camera RAWs to DNG (free) and then use them in C1.

Kerensky97: Wow, now I'm really wondering why Kodak Gold has been sold out everywhere since November. How much stock was shifted away from store shelves over to Fuji to be put in a different box for this release?

In the meantime I finally got around to trying out Kodak (not really)Professional ProImage 100 film and I like it more than Kodak Gold anyway. Less of the 90's holiday snapshots color, a bit more natural saturation without a smooth even grain. Plus it's cheap film to boot.
Very usable for people who scan negatives rather than make prints.

ProImage is great. But a little less forgiving on exposure than the high end films

Link | Posted on Jan 15, 2022 at 10:45 UTC

So Fuji basically discontinued all film lines. The last color stock is rebranded Kodak, and the black and white stock is probably manufactured by Ilford

panther fan: Interesting idea (for all manufacturers) but also Nikon would be an alternate mode. Where if you shoot just one file type, with no redundancy, it is written alternating to the two cards.

So card 1 has:
Image 1
Image 3
Image 5

And card 2 has:
Image 2
Image 4
Image 6

This would be an incredibly easy way to double throughput and write speed with no extra hardware needed. {if only a camera was open source for such experimental features}

@Brett8883
Well even in that world there is still the need for redundant media in the camera. Not all shooting scenarios are the here described high speed / single event type where you can benefit from the increased write speed.

There are still scenarios where you want a true simultaneous backup.
1. an internal SSD in the camera also is not more or less safe than a regular SSD. You also wouldn't trust the SSD in your computer with 4TB of data without any backup. There are hundreds of scenarios where that can go wrong
2. smaller cards are your friend when it comes to safety. If you are on a trip and regularly swap cards, and then fry your camera on day 11 in saltwater your would only lose that last part. Not all 4TB of internal storage with no backup
3. Splitting media is also an important safety measure. By storing the two cards in different places/bags you are better protected against common causes of image loss, like bag theft/ misplacement, camera theft, and other accidents

Your over ambitios math actually works out in our favor here

In on case you have 25% of total loss
In the other you may have 50% chance of some loss but only 6.25% of total loss. I take those odds

Also in reality it's more. 0.01% of total loss vs 0.02% of some loss with 0.000001% chance of total loss. I take those odds.

@Ellis

If you import with a DAM who the hell cares how the RAWs are named. That's why you have a DAM

If you manage manually or by hot folder/ session. You are probably not renaming anyway.

And the whole client side is export naming. Here you can use whatever naming convention anyway.

Would only really matter if you have a JPEG only straight to costumer worklfow. And then you don't need the speed increase anyway

It's an option. You don't have to use it.

Also, the import is potentially also twice as fast if you simply get a dual reader. Also, why rename? And if you do so why not name by timestamp? Also, it would be pretty easy for most import software to support twin imports from two sources at the same time.

Or if you plug int he camera via USB, the camera could actually merge the two cards and present them as one on the interface

If you followed the discussion this is not block-level raid 0. So if one card failed you only lose half the images. As described above that is not as big of a problem as it sounds, as in a 30FPS burst, you basically still end up with a 15FPS with nearly identical images. It behaves more like an organized JBOD instead of Raid in this way.

Also, SSD failures are so low, because the don't have an interface that needs to be replugged hundreds of times. Other than that they are not more or less reliable than CFexpress cards. In fact, they use the same chip and have the same controller. You can even buy a dumb breakout cable and plug an M.2 SSD straight into your camera if you want to.

panther fan: "or ‘Auto Distortion Control’ is turned on"

What a strange caveat. Isn't that supposed to be an always-on feature?

@Horshack
No problem. Yesterday, I tried to prove you wrong by doing the math on two consecutive 5 parameter Brown-Conrady distortions and trying to transform them into a single distortion without any luck. Almost convinced me it couldn't be done. But I guess my aerospace engineering degree is worthless and I just failed on the math.

Good to know it's possible and we are on the same page now :D

If the setting actually disables both distortion and CA control that's a much bigger problem. Especially with many lenses (like their own 24-70 F2.8) now designed to take heavy advantage of it

@PredatorsPrey
What camera are you talking about. Regarding card speed I have the most experience with Sony and here bandwidth is not shared.

The compression algorithm is the bottleneck on old 1-4th gen cameras, which is why uncompressed RAW is faster than compressed RAW/ JPEG. But I am quite sure uncompressed RAW would see a big write increase if you alternate the writing.

I mean we hopefully agree on the basic principle. If you have to calculate
x + 2 + 3 and the calculation is known beforehand. It is faster to pre-combine +2 and + 3 into +5 and then in the time-critical calculation just calculate x + 5

You can do the same for affine matrix transformations:
https://en.wikipedia.org/wiki/Affine_transformation
"The advantage of using homogeneous coordinates is that one can combine any number of affine transformations into one by multiplying the respective matrices."

But distortion correction is not actually an affine matrix transformation but based on the Brown-Conrady distortion model math (if I am correct) with a series of radial and tangential distortion coefficients. Adobe describes what they are doing here:
http://download.macromedia.com/pub/labs/lensprofile_creator/lensprofile_creator_cameramodel.pdf
And they are doing exactly what we talked about. The green channel just gets the geometric distortion correction and R,B get a combined correction
