Originally posted by IchabodCrane It's limited to build an entire price comparison around one prime lens. Sure, the Pentax 50 mm at $181 is more than the Canon but really, is it that big a deal? It's not like we're paying $200 more for the thing. Besides, when you look at it from a low-light perspective, that Canon lens (Nikon, too) is equivalent to a Pentax at f4 or f5.
f/5? Really? Pentax may claim "up to 3 stops", but realistic use is more often about 1-1.5 stops. Or maybe you were including ISO noise performance? I might give you that one vs Canon, but not Nikon.
I've done plenty of low light indoor shooting, and I would take a Canon Rebel with 50mm 1.8 over a Pentax K50 with kit lens any day. The number of usable shots is at least 50% higher (I'm ignoring the zoom part, as it isn't relevant to the discussion).
Also, I'm not basing my whole comparison on one lens. It's just the one that angers me the most.
If I could afford to spend $500+ on individual lenses, it would probably piss me off even more that a Canon 28mm f/1.8 is $450 while the Pentax 31mm f/1.8 (the closest equivalent still made) is $1200.
The Canon 35mm f/2 is $300, while the Pentax is $400.
The Canon 85mm f/1.8 is $420, while the Pentax 85 isn't made anymore, and the 77mm f/1.8 (closest match) is $1000.
The Canon 20mm f/2.8 is $500, while the Pentax 21mm f/3.2 (again, closest still made) is $570, despite being slower, narrower, and APS-C only.
I've reached the conclusion that the reason Pentax makes strange focal length lenses is because they don't want direct comparisons to Canon/Nikon/Sony.
I'm not saying Pentax should be *cheaper* than Canon/Nikon. I'm saying that it's ridiculous that they charge such a huge premium, even on lowly plain DA lenses (no *, not limited, etc)
Also, why is it that nearly all modern Pentax bodies are weather-sealed, but only a very small fraction of lenses are available in WR versions? Are any of the limiteds WR? Any primes at all besides the 100 WR and the DA* 55?
