Originally posted by enoeske Stabilizing a 35mm isn't that big of an issue. It is small and compact, but not sure if its moreso than the nikon 35 or canon 50.
As a 35mm it is smaller than Canon's 50mm. That's quite a feat, likely only achievable by limiting to f/2.4. In-body IS allows for weight savings in the lens which it is clear the Nikon cannot achieve without adding even more weight. The Canon EF 35/1.4 USM is a monster.
Stabilization is a HUGE when it comes to exposure. It's the raison d'etre of the Pentax lens line-up and focus (sic) on primes. In a real life shot at 35mm FL that's an easy 2 stops and provides a clear advantage over the Canikons.
What I sacrifice in light I gain in sharpness; and what I gain in ISO with new bodies I make up the difference easily (ISO 400 is the new 200, etc.) One simply needs to stop this lens down less to achieve excellent sharpness than one would with Canikon. That's the Pentax design concept.
DxOMark scores are very useful but are no substitute for real world situations where IS makes sharp shots readily available. This is simply an advantage Canikon cannot get to in any way with primes. I shoot both Pentax and Nikon and this a definite Pentax advantage.
Everyone gripes it is not faster, but then it would weight substantially more negating some of its size and distortion advantages.
I wonder if the t-stop difference between the Pentax and the Canikon's has anything to do with the coatings, like those we see on the DA 15 with its stellar flare resistance.
I'd say the Pentax DA35/2.4 is US$20 over-priced MSRP.
