Originally posted by twitch I'm not saying the lens line up poor, there's problems in it but there's problems in everyones line up. I'm saying very little of note has been released in K-mount for almost 5 years now. In that time according to my possibly faulty memory; we've had one super zoom, a re-skin of a (very nice) macro, and 2 plastic consumer primes to show for this past 4.5 years.
Since the DA15 was released in late 2008, Nikon as an example has had 20+ lenses
24mm f/1.4
28mm f/1.8
35mm f/1.4
50mm f/1.8
85mm f/1.4
85mm f/1.8
200mm f/2
300mm f/2.8
70-200mm f/2.8 VRII
70-200mm f/4
10-24 (DX)
18-200 (DX)
18-300 (DX)
55-300 (DX)
16-35mm f/4
17-35mm f/2.8
18-35mm f/3.5-4.5
24-85mm f/3.5-4.5
24-120mm f/4
28-300mm
80-400mm f/3.5-5.6
200-400mm f/4
60mm f/2.8 micro
and a couple of tele converters, flashes etc ...
I'm not crying into my skinny latte about this, and I'm enjoying shooting with my 20 year old FA limiteds and my K-5 a lot, however the lack of momentum for k-mount looks very real to me.
You know, Nikon releases new versions of their lenses regularly to keep buying their lenses. Often the updates are barely skin deep. Sometimes the updates have to do with VR improvements, where Pentax releases their image stabilization improvements in their cameras.
I don't see updating 15 year old lenses (the first FA limited was the 43 released in 1997) just so you can tack an extra 10 percent surcharge on the "new release." Yes, Canon and Nikon both regularly re-release lenses, but Pentax, not so much. The 50 f1.8 design you list in your list there is probably 50 years old. I can't believe an upstanding camera company like Nikon would even have such an old lens in their portfolio.
