  • Imagine a flashlight shining onto a piece of cardboard from a certain distance. Without changing position, the circle of light produced by this flashlight is the same regardless of the size of the...

  • It's very confusing because these terms are arbitrary jargons. On top of that, even many camera manufacturers use the terms interchangeably because their goal is to sell merchandise but not to...

  • nonuniform,

    While I agree that art shouldn't have boundaries and labels can sometimes be silly, but a painter ought to paint and a sculptor ought to sculpt. There is no doubt that his works are...

  • Kevin Barrett,

    I don't think the debate is about whether or not Karcz is an artistic or about whether or not his works are art. He is an artist and his works are art.

    The debate also isn't...

  • NancyP, you really can't compare Karcz with Jerry Uelsmann. (1) Uelsmann takes every photo he uses in his composites. They are all his. (2) Uelsmann's works are hand-crafted in darkroom. It takes...

  • What? The same product is offered to different customers at different prices? Base on what exactly? Huh, I am not a lawyer so I don't know. If there is any lawyer here, maybe you guys can tell be...

  • Richard, I have more time to make a more proper illustration to explain my points: https://i.imgur.com/6Mb3ifR.jpg

    I know I am a little off topic right now b/c I'm talking about the "equivalent...

  • Actually, with the diagram I was trying to illustrate that how it is impossible for the light, after passing the lens, to get bent inward to ONLY COVER THE SMALLER SENSOR AREA but not more. Oh...

  • We are still not communicating. I edited my post above. See the better illustration here: https://i.imgur.com/rCtDFj0.jpg

  • Look at the diagram again on that Panasonic article. The "cone of light" projected by the lens won't change when a smaller sensor is place there instead (because the focal distance won't change) —...

  • I edited my post while you post. New edit here:

    The calculation you mentioned doesn't mean that the AOV is dependent on the sensor size. What it shows there is how may you calculated the AOV when...

  • You are not getting what I am saying ... and IMO, you aren't getting the explanation from the 2 articles either ... The calculation you mentioned doesn't mean that the AOV is dependent on the...

  • Correction: In the illustration linked above, the text should read "This gives the illusion of a ... " instead of "This gives the illustration of a ..."

    This is the link for the corrected ...

  • The sensor size affects the FOV but not the AOV. Think about it this way: With a zoom lens, you get a wider AOV on the short end and a narrower AOV on the long end. You accomplish this by turning...

  • You are confusing ANGLE of View (AOV) with FIELD of View (FOV). I understand that many people, including camera manufacturers, often use the 2 terms interchangeably when they really shouldn't. Read...

  • {Continued from the last post]

    With the same lens, in order for a DX sensor to get the same FOV a FX sensor would capture, the DX camera needs to shoot from farther away. Inverse Square Laws...

  • You say, "If you use a (longer FL) lens to give you the same field of view as you're getting on the D7000, then you get to exploit that extra sensor region, and gain additional light/information...

  • Your explanation baffles me. You say, "... the smaller sensor can only see the inner, bronze-colored cone of light, the rest of the original yellow cone of light is no longer available for capture....
