Originally posted by str8talk83 I’ve noticed that the line is made up of small, light, well built but “slowish” lenses (from an aperture perspective).
Just to add another aspect of the design thinking for the limited series: Because of IBIS (in body image stabilization) or SR (shake reduction) feature on the Pentax DSLRs, the lenses do not need the extra size for VR or IS and with the ability to shoot handheld at slower shutter speeds, fast glass is less a priority. And....I see low light results daily from Canon, Nikon, and Pentax users and Pentax really gets exceptional high ISO results relative to the others at the same ISO.
As far as the size or weight of the K-1 relative to Canon or Nikon full frame models:
Yes, itʻs heavy at 924g if you compare it to other entry level models: Nikon D610 758g, Canon 6D 770g.
Yes, when compared to other DSLRs in its price range: Nikon D750 750g, Canon 6D II 685g.
But quality-wise, the K-1 is a flagship (without an entry and midlevel siblings), and itʻs an average weight: Nikon D850 915g, Canon 5D IV 800g, Nikon D5 1415g, Canon 1DX-II 1530g.
And even then, on average Iʻd say the non-limited Pentax lenses are generally the same or lighter:
Pentax HD DFA 24-70mm f/2.8ED SDM 787g ($1100)
Canon EF-L 24-70mm f/2.8L II USM 805g ($1700)
Nikon AF-S 24-70mm f/2.8E ED VR 1070g ($2400)
