Following the notes from Richard Sayer on this, in order to get the effect of a 50 mm lens on a full-frame camera, II set the 18-55 mm lens to 35mm on my Canon Rebel with its APS-C sensor.
@robz@helenhall Ah, thank you ladies for your words on the composition. Now, that thing about the lenses....I've just learned this as well...a full-frame sensor is the same size, as I understand it, of a piece of 35mm film that would be exposed in a film camera. But many dslr cameras use a "cropped" sensor....smaller, more like 24mm (cheaper to make, cameras can be smaller). That results is the sensor seeing less of the full breadth of the lens as the lens is calculated for full-frame. ie: a 50mm lens shows a 50mm view on a full-frame camera but would be cropped on a smaller sensor. And so, in order to get the same view, one has to adjust...by a factor of 75% or 1.5 or the lens size...eg a 50mm lens on a full frame sensor gives the same view as a 35mm lens on a cropped sensor. Have I totally confused you? hope not...and as I said, this is all new to me. And I think unless you are doing the nifty-fifty challenge here, it probably will never mean that much in our world of shooting...lol...
@granagringa I'm pretty sure i've got the physics of it now that you've explained it. But why bother? I read somewhere that the result is interpreted better by the eye - more natural proportions - would that be the why? And from all of this it appears that I can totally ignore it for my camera LOL !!! Thanks for the info! :)
