Originally posted by mariakruse When using either the Canon or the Nikon I was aware most photographers referred to 3 lenses as the basic, must have lenses; the 14mm-24mm, the 24-70mm , and the 70-200mm; They called this the Holy Trinity of lenses. Is it the same for Pentax cameras If not, what 3 zoom lenses would be thought of in the same way?

The 'trinity' isn't true for Canon, who don't have an obvious alternative to Nikon's 14-24mm. However it's unusual to find Canon professionals who don't own the 24-70mm and 70-200mm pair ... but the choice of third 'main' lens varies enormously (with a 50mm being a common choice for full-framers).
Prime-oriented full-framers often have the 35/50/85 trinity as their key lenses.
I'm new to Pentax, but the trinity I'm aiming to use for people shots (fashion and portraiture)
30mm f/1.4 (Sigma)
50mm FA f/1.4
100mm 2.8 Macro (Samsung == Pentax)
And for weddings:
17-70mm f/2.8-4.0 (Sigma)
100mm 2.8 Macro
with the 30mm f/1.4 and 50mm f/1.4 on standby for when the available light fail.
For hiking:
17-70mm f/2.8-4.0 (Sigma)
70-300mm f/4-5.6 (Tamron) (not the best lens I know, but sometimes I just want the reach and don't care about the quality so much)
18-55mm f/3.5-5.6 DA AL WR for when I don't want to risk the other lenses in the rain
