You probably will use the same argument if "cognitive dissonance" is replaced by any other insulting words. It's never your fault, of course. It's all on me, because I am easily offended. I am too thin skin. Sure. Why not.

Since when the responsibility of supporting a statement one makes rests on the reader/audience rather than than on the statement maker himself? Consider this scenario: "Ladies and gentlemen of the jury, my client was not at the crime scene when the crime happened. I am not saying anything more...

Sounds to me that you don't consider it an insult when one member says that another member is suffering from cognitive dissonance. Your standard is certainly differ from mine. but since you are a moderator on this forum, I guess I will have to go with your standard. Well, as the risk of being...

I understand how a anamorphic lens squeezes the image. But the squeeze has nothing to do with the film format. It doesn't know nor care what film is in load in the camera, it squeeze the image just the same.

But did Nikon (market) designate that 180mm f/2.8 ED AIS Nikkor as it is specifically for 35mm? Of course that 180mm f/2.8 ED AIS 180mm f/5.6 Nikkor-W is used for a 4x5 camera because of the lens mount, which will not fit their 35mm camera. But are you saying that even without the lens mount...

I did say, "... lenses specially designated for different film sizes (note that I said different film sizes, not different format cameras). Did the Olympus lens you mentioned had a designation saying it is specially for half film film? Tell me what this Olympus lens is, so I cam look it up. I...

A " cognitive dissonance" that I am "suffering" from? Wow! That's so rude and so uncalled for. Do we have to insult each other with words like these? I may have argued in a passionate and blunt manner here but I have never used insults on another member. Wow. Simply unbelievable.

Oh boys, this is exhausting. Back in the days, the terms "crop factor" and "equivalent focal length" didn't exist. We just knew and understood that as the film size you use increase, you need longer lenses to get the same FoV as when you used a smaller film size. And, back then, a lens is a...

Not so. Pperhaps this is just semantics, but, in reality, a Metabones does NOT reduce the focal length of the lens, but rather it alters the focal length of the "system", which is to say, the optical system created by combining lens+Metabones. Metabones is very particular and careful in the...

That is so NOT what I posted. Again, please read my post carefully. Though I can understand why you misunderstood my words. First, please note in my post that I enclosed the word magnification with quotation marks. I did that because it was the word YOU used and at the time I didn't agree with...

(A) Can you cite a reliable source that says that a crop lens does NOT shrink the image circle like a Metabones. That IS what I am psoting here for: Confirmation. (B) Do you agree that if (I am saying IF) a crop lens does shrink the image circle down to fit the size of the crop sensor (similar...

Guys, reading back on your posts, many of you appear to be arguing with me about a full frame lens mounted on a crop sensor lens. But, please, I am NOT talking about that at all. I fully understand and know why crop factor applies in this situation. However, I am talking about a "CROP LENS" on a...

The "magnification" is determined by the AoV the sensor is capturing, which in turn is determined by the amount of the area of the image circle is being captured by the sensor. So, yes, my illustration shows a different magnification, because, now the amount of the area of the image circle is...

No. I did NOT crop the image circle. I DID resize it. Please look at my illustration carefully. I am posting it again below. Note that the crop sensor size is the same size in the both images, but the image circle on the right image is smaller. No. As illustrated by the Metabones white paper...

Please read my post carefully before you reply. Thanks. (1) Guys, I have never made a claim that crop lens does or does not shrink/reduce/compress the image circle. I post a QUESTION to ask whether it is true or not. I have read that crop lenses do shrink/reduce/compress the image circle—much...
