If you are arguing about 'equivalence' with Joe the "Great Bustard", then simply ask him why, after he started to sufficiently explain what he meant, nobody took issue with what he was saying.

Please link to an example where I failed to "sufficiently explain" what I meant.

I just replied to your previous post, but it disappeared when the moderator pulled your post.

Disappointing, isn't it?

Here is part of it (most of it was lost), regarding clear explanation:

Funny you say that, 'cause when I say it much more simply:

Equivalent photos have the same perpective [sic], framing, and DOF, which will result in the same total amount of light falling on the sensor, which will result in the same noise for equally efficient sensors.

Compare that to DPR's explanation:
Sigma's choice of F1.8 as maximum aperture isn't a coincidence; it means that the lens will offer the same control over depth of field as an F2.8 zoom does on full frame. What's more, it will also offer effectively the same light-gathering capability as an F2.8 lens on full frame. By this we mean that it will be able to project an image that's just over twice as bright onto a sensor that's slightly less than half the area, meaning the same total amount of light is used to capture the image. This is important as it's a major determinant of image quality. Essentially it means that APS-C shooters will be able to use lower ISOs when shooting wide open in low light and get similar levels of image noise, substantially negating one of the key advantages of switching to full frame.

Did you, or did you not, say that my explanations were too long and incomprehensible?  Seems my explanation above is even shorter than DPR's (not that I am complaining against DPR's excellent wording).

The problem is not that most people are ignorant fools, the problem is that some people tend to make simple things convoluted and indecipherable (then resist fiercely when you try to get them to explain what they are on about in comprehensible terms).

Funny you say it, 'cause I can link and quote quite a few examples of the exact opposite.  In fact, this just about sums it up (Crocodile Gena was one of my former IDs, in case you didn't know):

You have a huge number of former IDs, Joe.  That should tell you a lot about how effective your 'teaching style' is.

I was hoping you would bring that up.  One of my former ID's, "g r e e n p e a" was permanently banned after responding to this post of yours:

The entire content of the reply to that post of yours was:

Not just DOF, boggis, but the total amount of light projected on the sensor, which will result in the same noise for equally efficient sensors.

Funny how I was permanently banned for posting that, don't you think?  'Course, that was back in the day when Phil Askey was running the show, and, well, he had problems with not only Equivalence, but understanding pixel density as well.

I wonder who filed the complaint on that post, anyway?  Any ideas?  Could have been anyone, I suppose.  More to the point is why that post got me a permanent ban.  I wonder if it's just coincidence that my permanent bans stopped after Phil Askey stepped down.  What do you think?

I did notice that when you relented and started using a complete explanation for what you mean by 'equivalence' there were suddenly no arguments in the offing.

What you say, and what happened, are two different things, boggis.  Unless you can link and quote an example, I'll just have to say it's another example of someone intentionally misrepresenting me.

People are not stupid, and they will acknowledge facts quite readily when they are clearly explained.

Boggis, in the deleted posts, I linked you acting exactly opposite that.  Would you like me to link it again?

Ratios are not in dispute, nor is the advantage that a larger sensor can yield.  Creating a dispute takes either incompetent exposition or deliberate intent.  (Or both, I suppose.)

Link and quote where I created a dispute.  Again, in the deleted posts, I was able to link and quote where it was you, not I, who was doing exactly that.  Again, please ask if you need the link.

The OP here is testing your claim that, for some reason, users of small sensor systems are ignorant of the advantages of larger sensors.  I suggest that you let him gather his evidence then you can debate him with your evidence to the contrary.

Honestly, I have no special knowledge of what mFT users know or don't know.  But I do know what I've said, and I do know what you've said.  And let's just say that the evidence clearly supports my side.

However, if you disagree, please, post a link and quote of me making Equivalence "too complicated" or "unclear".
