Insightful post!
Here are a bunch of photographs taken with a variety of lenses. Only the last couple were taken by me, the rest are from FM, I am posting only for the sake of discussion.
At least 4 from the set are from Canon lenses.
Each lens clearly has a character, that is repeatable under similar conditions for that lens. This character consists of elements (to paraphrase Jman) including: \"bokeh, color accuracy, sharpness, macro and micro contrast, smoothness of transition from in-focus areas to out of focus areas. Smoothness and color of skin tones, etc.\".
For some of these lenses the character is so strong it can uniquely identify the lens, almost forming a visual signature from the lens.
This is obviously subjective, but it goes beyond the idea of \"colourful\" or \"appealing\".
How do you and your knowledgeable friends discuss this concept holistically?
Thanks.
Can anyone list the lens used (without checking exif of course)
My guess is that many of these could be from the same lens or any of a dozen different lenses.
A few are distinctive, like the triangular bokeh.
And this is just an honest question from a relative newbie 
No worries.
You said it could be one of a dozen lenses, you didn\'t could be any lens, right? What cues did you use to narrow down?:
Funky / creamy / lively bokeh, CA, soft, sharp, vignetting, microcontrast, colours etc right?
This is not about being able to uniquely identify a lens, rendering is about about the way a lens represents a scene under a particular situation, or it\'s style.
People sometimes use phrases like \"look\" or \"how a lens draws\" to mean the same thing.
It can be used to discuss a specific part of the picture, like \"I like how the object has been rendered\", or the style of the lens: \"It renders like the 50 1.0 L\". It can go further to the look of lines of lenses or brands - L glass look, Zeiss look, pre asph Leica look etc.
Just as bokeh is subjective but useful term, so too is rendering, especially in forums like the alt forum (with lenses of wide ranging rendering styles), where it is commonly used.
Canon describes the new 24-70 L II to have increased clarity and 3-dimensionality - they\'re describing the look, or rendering style. Seriously...
