The Difficulty in Explaining Equivalence

i will test using 10:1 microscope objectives using very acurate system and tell you the results between apsc and FF.

posting images is more efficient at teaching/ showing effects than maths and nunbers 😁 you only need the intellegents to watch a utube on how to fix your car. but if you like you can post in numbers the equivalent of your teaching methods 🫣 will wil keep the task simple ,how do i take the tire cap off the stem.🤨

im sorry that a photograph is a puzzle you havnt figured out yet. your not alone. photographers are still second guessing themselves with maths 🫣😎

I have read your posts about your interactions on DPR. The debate should be out in the open, otherwise it is just two people talking past each other. But then that is a sure way to get banned or sandboxed where you were posting. I just cant be bothered to argue on DPR anymore, about anything.

Now, I believe personally, that the theoretical basis of the "Equivalence" question is correct. But when we throw into the ring, different cameras with different sensor technology, some recent and some old, and we add into the equation different lenses with different resolving power and such, the water starts to become muddy and the precise differences between formats, become less accurate to a greater or lesser degree. It is up to us as individuals to decide the usefulness of this concept.

This article by the rather arrogant Ctein has some good points in the comment section, from both sides of the argument.

There are other areas of ignorance in our little world of photography, that I find more annoying.

That's like saying, "Police have been held accountable by the courts when innocent people have been released from prison."

Absolutely. However, I dare you to find a post of mine in this thread where I deserved being sandboxed, keeping in mind that none of my posts were deleted. I would especially like to to compare and contrast my posts vs Tom Caldwell's and jalywol's posts with regards to forum rules. I also dare you to explain why this thread was moved from the Canon R forum when the mod knows I shoot Canon. Lastly, I dare you to explain why the admins did not respond or act on my complaint. I'm being serious, here -- if you can side with the mods/admins over this, I'd really like to hear it.

For reference, if I posted the same thing that Tom Caldwell posted:

I don't set myself up as an expert but am willing to accept the theory of equivalence despite asides that I and others denying it...If you cannot directly answer my direct question and keep spouting your accusations of equivalence denier from your podium I will consider you a trouble maker on this forum and act accordingly.

If I posted a similar challenge followed with a similar threat, what do you think would happen? If I had replied with, "Why? What's the point?" as jalywol did to a much friendlier question that I posed her, what do you think would have happened?

The above is but one example of gross hypocrisy and lack of accountability of moderation on DPR -- I can link to many more.

Assuming they read the posts here, absolutely. In the same way that Putin loves to hear all the people moaning about Navalny's "untimely" death. What's your point?

The fact of the matter is, mods, like police, are not held accountable for their actions, and the reason for this is simply that the admins do not care. The mods' primary purpose for them is to block commercial spam and shield them from anything that might make them legally culpable. Aside from that, they can run their fiefdoms as they see fit. Mind you, I'm not saying all mods are bad, just as I don't think all cops are bad. I'm merely saying that there is no system that holds them accountable for their actions.

Now, if you don't mind, there's a humanitarian food truck convoy heading out, and I need to get my drones loaded with US missiles paid for by US taxpayers so I can remove the threat (thank goodness I'm not held accountable, either!). 😜

admins dont care as its a sales site( they promote what the admins are doing). the more the admins control the comparrisions the better the sales amounst brand Enthusiasm. if there was no brand loyalty and we were all honest with ourselves we would be all shooting Sony 😁🫣

DPR is a commercial enterprise. They set the rules, and they chose to allow some bullies in amongst the moderating team. The DPR forums are sinking into a swamp of mediocrity, hardy a tragedy when some little asshole on a power trip decides that they do not want my participation.

No, no, no, Don. Sony do not do shift lenses. Its Nikon or Canon.

so what is correct 93 or 9iii or even 9III maybe 9iiv 🤔 ive got it now sony a 9. 20+45-56x67/45 🫣

Yep -- some prefer to be King Shit on Turd Island than a judge in a just court. As wrongdoings in the world go, it really is the smallest of First World Problems in the end. Nevertheless, just one more disappointment that hits close to home. Not to worry -- unrelated bigger disappointments with much more terrible consequences are sure to be made known in short order. 😁

intellegents is inventing contraptions/systems not substanciating inventions.
yesterday my daughter wanted me to print some "Plicker cards" as she is a science teacher. and while i was delivering them to her
my mind reversed engineered what they were used for and how they were designed. wouldnt matter how many computer science/engineering degrees a person has
this was invented by a practical person ,probaly a teacher in the industry with a need. what a great invention, i loved it. i worked as a systems designer for apple back in the 80s.

As we are blindly drifting towards a serious war here in Europe, the antics and ignorance of Mr Caldwell are the least of my worries (yes I read the BS in the DPR thread). I am more worried about one of our dear leaders asking my son to die for Kiev.

I agree it is annoying that a pleasant distraction to daily life has been spoiled.

i was impressed with the Z8 image comparrision on the MF forum. shame the processing was dodgy'ed up to make it look inferior.

😇ignor it unless you seek the true intention 🤔 nobody learns anything by given the answers along with the questions 😊

I could do that as well with my 10x microscope objective (and I could compare full frame and APS-C and 1") but it's not the same thing. That would no longer be testing with 'equivalent' focal lengths for each format, which was the way I did it, so it would illustrate a different principle.

If Mr Gritz does respond to my last message, I think this will be my response. That should close it all off!

LOL, it is admittedly quite funny to watch.

Yes, DPR forum moderation is quite haphazard.

The m4/3 forum seems to deliver a weekly "here's why m4/3 rules the world" post that is full of faulty logic and results in 8 pages of stupidity. TC seems to be getting increasingly grouchy but not with the actual protagonists.

I didn't say your photos were puzzling.

I said they might or might not be dodgy as support for the agenda you push.

I would prefer it to be out in the open too, but as you know the moderator will eject anyone who he perceives is not agreeing that m4/3 is equal or better than FF.

And if you also throw in the fact that a large number of people are viewing images on small screens, the differences are difficult to see.

Thanks, I will have a read of this.
