If I'm shooting both the 1.4 and 1.2, I will know what images were with the 1.2. I will see the difference and that translates to a look I want.
Some can see the Unqiue look in lenses, others can't. (Lomo Petzval Lens is a good example.) I like the 50L's unique look to the other canon 50mm's and It matters more to the photographer than client. Most clients can't tell the difference between a 550D and 1Dx in print but it's the photographers job know the difference for them.
So far none of you photographers has managed to pick out that "unique look", which illustrates my point perfectly and the extent of your credibility.
I can understand the 50% more light than a 1.4, I can understand the "I only use 'the best'" mentality, I can understand the satisfaction of arriving and working with top of the range gear and I can understand people aspiring to own that gear and enjoying using it for what it is. I cannot understand this constant "unique look" bull that nobody can actually identify, sure people give esoteric descriptions of subtleties mere mortals just can't see, bless us and our poor blind deluded selves, but I hate the fact that when challenged by somebody with a bit of experience and confidence every single one of you aficionados baulks, then fails to identify images shot with that "unique look".
However, I don't expect someone like yourself who hasn't shown any images of artistic merit of your own to understand this viewpoint. Perhaps you can attempt to map that on a test chart somewhere to add some credibility to your portfolio.
Of course you could.... No wait, if we go back to the last time we did this you couldn't tell the difference between the 135 f2 and the 100 f2.8 when used for the same shoot, so why should we believe you now?
As for the rest of your comment, it is a cheap shot at trolling, not gonna play.
I do get the point you trying to make.
But but but.
Sometime you cant just tell the difference, or sometimes you can. But people wont believe you.
I am referring to portrait shots. I wish I can share the pictures.
People argue on what they see and believe in, we can not blame anyone.
Remind me an instance. I am sure the color of petals is near to orange but she insist its near to red.
thus the argument. I can not give up because its really near to orange than red. but she insist sees otherwise.
maybe we are both correct, its how we see it.
Well Pdb, if you can not see it. then look again.
In my case, im still in doubt, thats why I ask..
good to know others also see the difference.
