Originally posted by dgaies But as others have points out, there is almost certainly more profit for them selling FA50/1.4 lenses than there could be on an DA50/2 lens selling for $125. Not to mention that if the DA50/2 would potentially hurt the sales of FA50/1.4 lenses, it would further hurt their bottom line.
Not saying it's impossible that they would release such a lens, I just think it's very unlikely.
But there is a flip side - for the consumer that is looking at the cost of a system, they can buy:
Pentax K-x & 18-55, black - $500
Pentax FA 50mm f/1.4 - $370
Total = $870
*OR*
Canon Rebel XSi & 18-55 IS lens - $630
Canon EF 50mm f/1.8 II AF lens - $120
Total = $750
Now, I know and you know that the Canon 50mm f/1.8 is a POS that has a decent chance of falling apart in the owners hands. We also know that the Pentax has sensor shift IS, and a whole bunch of other benefits, but the average consumer does not know this, and will not learn it from scrolling the price list at adorama.com, bhphotovideo.com, etc. All they will learn is that Canon is $120 cheaper than Pentax for what they perceive to be comparable gear. Then they will talk to the soccer mom next door that just loves the Canon she bought last year a Target, and the decision is done. Why would average Joe pay more for a product from a less well known company?
Now try the above example with my idea for a lens:
Pentax K-x & 18-55, black - $500
Pentax DA 50mm f/2 - $140
Total = $640
Now Joe is looking at a comparable product from the lesser known of the two companies for $110 less. That $110 might just be enough to pique his curiosity into looking at Pentax.
Don't get me wrong, I'm pretty confident that Pentax is not going to release such a lens, except if the DA L 35 becomes a runaway success.
