Quote:Rover points out that in the 35mm range f1.4 is about as fast as it gets for FF. It then makes little sense giving links to lenses not for FF, or lenses of a different focal length than 35mm on FF.True dat, therefore the references to 50mm lenses are beside the point. I should also point out that all the 35/1.4 lenses are not created equal: many of the old spherical ones were not known for decent quality at large apertures, so their 1.4ness was more for bragging rights rather than for unconditionally usable output.
Re: the lens teardown by Lensrentals... wow. Just wow. This is the real "tank-like build", not the Tokina kind - where metal-clad lenses snap into pieces because the actual structural pieces are held by something plastic and flimsy. I've seen a colleague's 16-50/2.8 blown into chunks because of that. Must be still serving as a paperweight in her house.
