Do you feel their f 0.95 lens should be manual focus only? I'm sure some photographers would use it, but it looks more like they're trying to out gadget Canon as opposed to trying to lead in overall sales.
Manual or AF?
I would have to use it first. I have no idea how it performs or what the intended use is. I often use my Wide Angle lenses in Manual mode. Why? I set the f stop to 8 or 11, put infinity at f stop indicator of choice (where this is available, I have manual lenses!) and have the absolutely wides depth of field for focus. You don't really need AF.
Also, read my comments below .... AF may be an expensive options to only prove a point.
I think sometimes you make something to showcase your technology prowess and industry Leadership. I will lean towards them making it to prove a point. Seems like everyone is talking about this. You can waste 10 million dollars on advertising or on a product and let everyone else advertise it for you.
I don't look at what Canon does, I don't care. I am heavily invested in Nikon and I am extremely happy with my Nikon gear and my decision. That said, Canon could come out with a Lens that seconds as a Coffee Thermos and has a built in Shaver and is F .5 .... wouldn't phase me in the least because I simply don't care what the other guy does. I am not going to dump thousands of dollars of gear just to get one gadget.
I believe there are those who want or need the .95. Some pros like to be cutting edge just to impress clients. Others, because they get a look that puts them ahead of their competition. Some people in general have to have the latest thing .... these are not reasons for the masses and most likely, many will not jump ship just for this one lens.
So, to make a short answer as long as possible ..... at the end of the day, I think this lens is just a marketing ploy. It ads credibility to the line and I will bet they purposely left AF out of it.
