Originally posted by aurele the difference between f2 and f1.8 is like inexistent for the vast majority of users. If you want a 35/1.4 the new Sigma seems very good.
Pentax stated that they won't produce f1.4 lenses in a close future.
However, i agree that the 35/2 is overpriced when you see the 35/2.4.
I actually just got a 35/2.8 macro Ltd beside my 35/2.4, so I'm actually going slower, but I just wanted to try out that lens. I know about the new Sigma and I may very well buy it. But the thing is, Pentax should have their own high-quality fast primes. But the only one seems to be the DA* 55/1.4. I am curious though; where did they state they aren't going to make new f/1.4 lenses anytime soon? I assume you are talking about new lenses, given that the aforementioned 55/1.4 has been around for quite a while now.
I know the difference between f/2 and f/1.8 is very small. That's my point: Pentax won't produce a cheap 35/2 because it would hurt sales of the 31/1.8 Ltd. There is the old FA 35/2, but that's in an old package, only half a stop faster and more expensive. Pentax wants to keep the 31/1.8 in production because that's a legendary lens. And maybe it is, but it still isn't terribly fast. Which makes it difficult for them to position other 35-ish primes. They can't be too slow because people will get zooms instead, and they can't be too fast because the 31/1.8 is the star of the show. So you have options every half stop between 2.0 and 2.8. This is all my perception, but that perception keeps me from being really excited about Pentax's primes. Which is why the Sigma appeals to me. But that's Pentax's fault. I'd rather see something like this:
- DA* 35mm f/1.4, emphasis on speed and image quality;
- DA-L 35mm f/2, cheap 'n cheerful, compact, still good IQ;
- DA 35 f/2.8 macro, because people like it so much.
You could say you don't need as much speed with the high ISO capabilities of e.g. the K-5. First of all, it's not all about speed, but also about subject isolation. With APS-C, you already lose a stop of that compared to fullframe. Pentax doesn't offer a fullframe solution, but they also don't offer many fast primes. Yet people continuously say (perhaps too optimisticly) that Pentax offers an alternative for fullframe. Secondly, lower ISO's are always better. Color rendition will improve as well as detail retention.
