Originally posted by urje Well, maybe people would think that way, but it doesn't sound very reasonable to me. The other way around would work as well: if the samyang is $300, why would people spend more on the FA35 and lose a stop of light? If the DAL35 is $150 and the images are the same, why would one spend more on an ugly, heavier lens that might even be the same speed?
If there's an FA35 for auction on ebay, the price depends on the number of bidders, and how far they want to go. With cheap, new alternatives available, I think the number of people interested in an FA35 would decrease, and it wouldn't surprise me if this decrease would be enough to result in lower winning bids. But what does it matter? In the end, I just pay for a lens what I think it's worth, and then I'm going to enjoy shooting with it and forget about the price. That's where the fun starts!
We won't know for sure unless we see how the two new lenses perform. the defining factor would definitely be IQ performance is worth the cost (bang for the buck).
at the moment, the FA35's price is dictated by it's discontinued status and high demand due to it's new found fame. remember, this lens cost less than $300 bucks til people started discovering how great this lens really is and for a 1/3 of the cost of the FA31. so people might want to ask themselves this question of why prefer the FA35 over FA43 (is it focal length?), DA35 (is it speed?), and DA40 (is it focal length and speed?).
I believe there is a certain specific characteristic of the FA35 that makes it appealing for users. if the new 35mm lenses could provide such IQ rendering, then it could affect the price of the FA35. otherwise, the price of the FA35 would remain constant or even increase.
