Beat it in what? The 15mm is so sharp, I have had 2 copies and they were razors.
Although it is supposedly the best fisheye for FF out there, it can still be improved upon in the edges and corners. Other than that, if they do upgrade it à la 70-200 F/2.8 II, optics wise, it wil be better.
The weather sealing and build is a nice upgrade i suppose. So on all your points your right.
In reality you make some good points, I guess I am just confused that Canon thinks people will pay for this lens.
I see it like this. This lens does not apply to APC users for a couple reasons.
1) It is so damn expensive for a fisheye lens.
2) Tokina and Sigma make 10mm and 10-17mm lenses aimed at that market.
Full frame users already have the option of a 15mm 2.8 that (please dont come at me with whatever you have seen if you dont own or have used one) did not need an update. It is a niche lens for most and I use it so much to know it works perfectly.
So this lens was suppose to address Canons lack of a full frame fish for 1D chips. While it does do that, it does it at a hefty price.
No thanks, I would rather move to a D3 and a 16mm fish. The cost might almost play even.
I think one of the strong points is that it is a proper fisheye for APS-C, APS-H and FF, and on FF it is both a circular and a diagonal frame filling fisheye. IOW, it is 4 fisheyes in one, and other than that we wil have to wait for the test results.
The Tokina 10-17 isn't full 180 degrees on Canon APS-C (owned one), although you can get about 183 degrees on FF with it without vignetting (tested that). Also, the edges and corners leave a little to be desired still. I don't know about the Sigma.
Kind regards, Wim
