3.) This resolution differential can clearly be seen in downsized images (as small 1800x1200 px for instance).

I'd like to see examples of that, I once had a very acrimonious thread conversation with a guy who swore he could tell medium format film images from 135 format digital images at 800px, turned out he couldn't. But I'd still like to see some examples of the D800 at 1800 showing "clearly" better resolution.

A lot of even high end pros don't have the faintest idea about colour. I have seen pros, real household names, wax lyrical about this lighting setup or that lighting setup because of a colour cast, yet not having a clue about camera profiling. It is kind of embarrassing the misinformed uneducated rubbish they come out with sometimes, particularly about colour, but hey, they are much better image makers and promoters than me!

Many don't do anything, they leave all that to "the retouchers", some use grey cards but believe WB is all that is needed for good consistent work while some, depressingly few, use colour cards and make profiles. It is funny, they know what light they like, they can tell you what time of day an image was made in their daylight studio from the colour on their calibrated monitor, but they couldn't tell you how to create exactly the same look with studio lights, or visa versa.

As far as lighting goes, junior movie light crew know far more about light than most high end pro photographers.


Sorry, I'm not 100% sure about what color profiling is, I'm not a pro or anything even close but it sounds like something I should know about.

Are you refering to the Camera Calibration tab on LR or ACR? How does that work? Do you create a custom profile for each type of lighting and save it as a preset?


Yes, the camera calibration tab in LR and ACR, you can make custom profiles very easily and quickly if you do a shot on set with a regular 24 patch colour card. The most popular and convenient one around is the X-Rite Color Checker Passport. I found the free Adobe app, DNG Profile Editor, to be a better piece of software than the inclusive X-Rite app.

I forget. What is the supposed "3D" supposed to be?

The EOS 3D is a fantasy camera that is supposed to be the ultimate combination of every bit of camera technology you could ever ask for in a relatively compact and affordable package.

Inspired by the film era EOS 3, which took every bit of tech Canon had at the time (zillion point AF, eye control, weather sealing, robust, high speed shutter, 100% viewfinder, EOS 1 series UI, etc...) and dumped it into a body that was just a little more expensive than the Elan (xx) series of cameras. Then Canon introduced the EOS 1v at over twice the price that offered one incremental benefit (bullet proof construction), but took away eye control and a little speed unless you bought the power booster grip. Note that every EOS 1D series camera since is based on the EOS 1v interface and PB grip-included cosmetics.

I would be willing to bet that the 5D III and/or its linear successor is about as close as we are going to get from Canon these days.

The 3 didn't have a 100% viewfinder, one of the main reasons I got two 1VHS's which did, oh and the ten frames a second  :) Running through a roll of film in 3.5 seconds is a thing of beauty!

....

however I'm not sure about this rumor.

This rumor makes it sound like "Canon came and visited us with a new camera that we got to look at and try."

If that is the case, Canon will know exactly who it is (or have a very short list.) If they signed an NDA ... and even if they didn't, I suspect that Canon would look unfavourably on this kind of disclosure - UNLESS it was specifically asked about and agreed to.

Additionally, any professional (working in a studio where Canon visits you is going to mean you're seriously good) is going to know that the colour accuracy of a file when viewed on a laptop screen is highly dependent on the ability of the screen to represent colour itself and without being able to use the images on a calibrated screen, the colours seen on some random laptop mean nothing.

I'd be almost prepared to call this rumor a hoax.

my thoughts exactly. why would canon do this?

its one thing for canon to get high speed cameras in the hands of professionals in the field for testing (ie world cup, olympics etc) but why do so for a studio setting? is it beyond canons capability to set up a studio at their R&D facility for testing....i highly doubt it.

They have always done that, particularly with the high end bodies and lenses, it is part and parcel of the normal testing process and it throws up inconsistencies and compatibility issues the labs and Japanese factory field testers don't come across. It also gets Canon high end user feedback, however perverse and badly informed it might be, and it creates a little clique for the studios. Being an Alpha tester for Canon is a feather in any studios cap.

WOOHOOO!

That, as I have bored many of you with, would be my dream camera, 24-28MP with a better sensor in a 1 series body.

Fingers crossed on this rumour, it would also be another interesting differentiator between the high MP Nikon bodies.

As for colour, in a studio environment particularly, there is no excuse for inaccurate colours already, though it is surprising the number of people, high end pros included, that just don't understand camera profiles, profiling, and a decent colour managed workflow, what are their assistants doing?

P.S. There have been so many 1DX deals around recently there might be a little more to this rumour than most, I'd love to know the fps, if it is aimed as a 1DX MkII it can't be slower than currently. If the 1DX truthfully was an amalgamation of the 1D and 1DS lines then it is high time for a camera with better "studio" specs than the 1Ds MkIII, if that got a high frame rate too it would be THE generalists tool. No more lenses for me this year  :'(

Lenses / Re: Return policy on lenses/equipment?
« on: May 26, 2014, 08:49:15 PM »
Playing Devil's advocate here.

Why should a store deal with the inability of the consumer to make a decision? More specifically what do you expect the store to do with the return? B&H have said publicly they would resell it as new, Vistek have said they absolutely would not, if you buy it new from them it is brand new to you. Which policy would you rather? How happy would you be if you knew your new lens or body had already been sold once or twice?

For whatever reason, the distance markings don't seem to be that accurate. Maybe I need to do some detailed measurements.  However, I initially took note of the following quote when I was reading reviews on the lens.

The below quote is from dpreview.com.

"The lens has a basic distance scale, with depth-of-field indicators for the minimum aperture of F16 only. Note that these are calibrated for use on full frame cameras; on APS-C the extremes of the indicated range won't appear as sharp"

Ah, that is referring to the dof scale, not the distance scale. The dof is different for the same aperture on ff and crop on the same lens and subject distance.

The truth is that all lens dof scales are "mirky" at best, they actually use a different coc values to actual reproduction values so tend to be generous at the best of times, but a crop camera will be just over a stop less on the dof scale than a ff camera, so on a ff lens dof scale if the f16 is suggesting good dof, then for your crop camera where the f11 marks are will be as good. The actual focus distance is still the same though.

It is clear that the focus distance markings on the lens will not be accurate, as I am using the lens on a crop-sensor camera.



Why do you say that? Distance is distance, crop or ff have no impact on that.

the fact that DxO have embarrassed themselves as "scientists" yet again by claiming the physically impossible.

Hmmm....isn't DXO a French company?  I wonder if any of their "scientists" were involved in that faster-than-light neutrino error a few years ago.   ;D

What's 60 nano seconds between friends? It doesn't matter that much does it?

Well I have 34 years of providing for myself and family by producing images, so I suppose you could say I know nothing.

On the other hand I could point you to the various articles, comments and such that point out the many inconsistencies, inaccuracies, and unmentioned "editing" (rewriting of the "facts") that have been made about DxO. Or that they claim to be scientists with scientific methods but won't actually share how they arrive at their end scores, so nobody, scientist or not, can check their "work"/opinions. Or point out, again, that they are claiming the physically impossible, nothing is perfect, not even a Zeiss 135.

But my dear dilbert, like the cartoon, you have proven to be a frustrating person to have a conversation with, you avoid direct questions (Does a 70D pixel enlarge as well as a 1Dx pixel?), rebuttals, and facts that don't align with your opinion, you change the subject, throw up strawman arguments, and seek to deliberately misrepresent what people say in their counter positions.

Bearing that in mind, I don't really care what your opinion is, or about the fact that DxO have embarrassed themselves as "scientists" yet again by claiming the physically impossible.

Hey there,

Well you have several issues. I think the camera and your gf did reasonably well, but clearly she didn't fully understand what she was supposed to be doing.

The sign on the front of the lectern is fine, unfortunately you are further back, in darker light, out of critical aperture dof and seem to be moving such that the SS was not high enough to stop your motion. You also have some pretty bad noise and jpeg artifacting, so much that sharpening is difficult.

Having said all that I did have some luck with PS Smart Sharpen with the Motion Blur option chosen with an angle of around 11ยบ using a mask on you so the sharpening only adjusted for your movement as the lectern and screen seem shake free.

If you want to upload a RAW file or two to Dropbox and PM me the address I'll see what can be done after removing the noise first. If not then remove as much noise as possible, then open as a smart object, make a layer mask of just you in white, then do Smart Sharpen with Motion Blur selected, play around with the pixels (they are looking for how many pixels you moved), and the angle setting, that is the direction of the movement.

That is laughable for several obvious reasons, first, they are saying the Ziess lens is perfect and causes zero resolution loss, that is impossible, it is either breaking the laws of physics, or their measurements are suspect yet again. And, just read any Nikon forum where people own both, and there are a surprising amount, they will tell you that is simply not true, yes the E does resolve slightly more, but 30% more, no.

315

Of course you're welcome to tell me that bigger isn't better :)

Bigger is only better if the smaller thing you are enlarging more is better than the native big thing.

You are not arguing bigger is better, you are saying smaller (pixels) are as good as bigger ones, that has been demonstrated repeatedly to not be the case.

So the 1Ds and original 5D have better IQ than the current 1DX, 5D3 and 6D?

So a 70D pixel enlarges as well as a 1DX pixel?

If you look at same generation sensors on a per pixel basis bigger pixels have always performed better than smaller ones.
