  • :-) Sorry for the delay in responding, and I appreciate all your answers. This last sentence of yours, of course, shows the difference in how people look at this subject. For decades, authors, ...
  • Nice shots!  I've got to find a way to get around, or perhaps just get over, my inability to see the screen well enough to accurately frame pictures on my DP2s and just use it more.  Maybe I need ...
  • Replied in video demo
    Yes, that's what they mean, and that's what I've been trying to communicate in past posts and quotes, such as these from a week ago: Commonsense Photography, by Leonard Gaunt, "the standard lens is ...
  • Replied in video demo
    In the example you quoted, there was no moving of the feet. I was trying, without success I'm afraid, to describe the effect of the change in focal length while the photographer was still at the ...
  • Replied in video demo
    You're right, of course, but the Gary Voth article, while mostly assuming use of a 35mm SLR, includes a recommendation to use a 35mm lens for APSC DSLR's, and the Sigma quote also says that the ...
  • I like the exposure triangle, too.
  • Replied in video demo
    I appreciate your response, and I don't disagree with many of the points you've made, though exceptions include the statements that focal length makes no difference to perspective and that ...
  • Replied in video demo
    Oh, you didn't need to dread it.  I appreciate the response and knowing why it worked for you.  If I want to go that route, I'll just have to pony up and try some.  Or maybe take a trip to a store ...
  • Replied in video demo
    That's useful feedback on the VF-21.  Every once in a while one comes up for sale, but typically for more than they originally cost new, and I just can't bring myself to pay it. I did buy a cheap ...
  • Replied in video demo
    I think of angle of view and perspective as two different things, the former being about how much I see in the frame and the latter about how natural/realistic the size and distance of items in ...
  • Replied in video demo
    I don't crop, and the 28mm equivalent lens makes the items appear smaller and farther away from me, the viewer, than a 50mm equivalent lens does.  Again, only a normal lens makes things in the ...
  • Replied in video demo
    Thank you, I enjoyed the video. It opens with the reason I almost always use a 50mm or so equivalent focal length: at 50mm the distance between Brando and the house looks the same as it does to ...
  • Ricoh had written that the 40mm equivalent lens should deliver "images with a more natural perspective and a more truthful sense of depth" than their 28mm equivalent model.  That language seems to ...
  • There have always been some here at DPReview who consider it a myth to link focal length to perspective. I still think it's just a matter of semantics, and no one I know of has yet come up with ...
  • I think the composition is fine; it's ignorance on my part that's the problem. I had to look up what an estuary was (and I just did a search for Broad Meadows Marsh, Passanageset Park), and I ...
  • Interesting picture and question. On the one hand, it is normal for my eyes to see nearby things as sharper than things further away; on the other hand, in this black and white rendering the most ...
  • That's potentially a helpful distinction, and why I had asked you if your using the term geometric distortion changed the subject of the discussion (though perhaps I should have said clarified). I ...
  • Replied in I see what I see
    Well, of course you can say I'm wrong if you like, but that doesn't change what my eyes see when I use different focal length lenses. This being a Sigma forum, I can also point out that they tie ...
  • Replied in iA+ -- A Trial
    I tried iA+ when first getting my FZ300, and my biggest issue with it was not being able to control the photo style.  I like natural, and I like standard with the saturation turned down a notch, ...
  • You have added the word geometric as a qualifier to the word perspective. Does that change the subject of the discussion? In that other thread, an announcement by Ricoh of a new camera with a 40mm ...
