Wide Angle Lens

The Pentax DA 10-17 any good? Price about the same as Tamron 10-24mm?

They are not comparable. The DA 10-17 is a fish eye lens.

Actually I see the DA 10-17mm as a complement to the DA 12-24mm in terms of wide angle coverage.
Even though former is a fisheye and the latter is a rectilinear wide angle, Pentax did put some thought in the angle of view of the two lenses.
The DA 10-17mm has an angle of view of 180 to 100 degrees while the DA 12-24mm covers 99 to 61 degrees of coverage.

Wow the difference of 2mm for both lens at the shortest range equates to 81 degrees of view? Or is this the characteristic of a fish eye lens?

Its the characteristics of a fisheye lens ...

Btw still don't get it if 10mm =180degrees then what about the Nikon 5mm FE or the samyang 8mm FE ?
Are they 180 or even more ?:dunno:
