Yea. Canon is definitely getting rid of EF.
But I don't quite get why someone would choose the 45mm TS-e over the 50mm f/1.2? Autofocus, bokah, low-light...
if it worked or was any good it would be talked about all over the forums etc... if they need to come to you then i suspect it isn't.....Since the question was asked, it seemed appropriate for them to post a helpful note. Its not like they were spamming the forum.
I think I had tried it a few years ago. For a P&S user, or a first cut at processing 1000 images, it might save some time, but, I'd still spend about the same amount of time fixing images in any event.
Nothing will ever beat the 24-105's price for entry into the L-lens club.
