DA 15mm Rectilinear?

Hi Folks!

Is the DA 15mm f/4 a rectilinear lens? That is, not a fish eye?

Thanks!
Dave

Yes. That's correct. It's rectilinear.

I was about to buy it, but ran into a DA 12-24mm, and also read one of the reviews that the DA 12-24mm is sharper than the DA 15mm.

So I'll hold off the DA 15mm for a while.

Pretty low distortion too.

Arguably so but the DA15 is not soft, has noticeably less CA, and it's much much nicer to carry around all day. (Speaking from experience of both.)

Absolutely true. The 12-24 is a horse, and not at all pleasant to use, though it's results are good.
I quite like using and carrying my DA15, and it's results are also good.

Its distorsion is quite negligible given its small size and boutique metallic build.

i do not think that 12-24 can be sharper than the prime. for the sharpness in the range I would take a 15/4

it is sharper than the DA14 prime and DA21 prime. the 12-24 lens is an exception to the IQ standard of the zoom lenses. it just performs better than some of the modern UW prime lenses. the DA15 probably is as sharp or a bit sharper than the 12-24 at the center. but the border and corner sharpness is the strongest points of the 12-24, making it more ideal for an UW lens. however, the DA15 has a tiny trace of barrel distortion which would be deemed insignificant or unnoticeable. also the CA control is way much better than the DA12-24.

Photozone's numbers have the 15 somewhat sharper in the center at all apertures, and the 12-24 significantly sharper in the borders at f/4 and f/5.6. But even in the borders, the 15 catches up by f/8, which is probably where the lens would be used most often. Considering the 15 always wins by a pretty hefty margin in distortion and CA control, I can't see the point of choosing the 12-24 on QA concerns. Of course, it could still be worth choosing simply because it's much more flexible.

Bought myself a DA15 today, even though I already have the DA12-24.

Planning to use the K-x with the DA15, DA21, Vivitar 28 Close Focus, DA35, Helios-44K-4, and DA70 as a lightweight/small travel kit.
