Unless it has IS, how is this a tease to Canon users? Maybe if it is as good with AF for $400, otherwise suck it up and get the 135L.
Yeah Samyang lenses are not what they used to be. They made their mark with the 14mm f.8 which was great quality for 1/5 the cost of the canon counterpart. For that much money off the competition people were happy to deal with no electronics. Their latest lens their fisheye is $500 which is just $100 less than the very good sigma full frame fisheye yet the samyang still has no auto focus and no auto aperture, no exif reporting, and (according to the sample pictures on their web site) soft corners. Why would anyone bother? If they make a 135mm and price it over $300 I think they will have a dud.
