No such concept, cause Pentax is ONE and Pentax is MANY
I know ppl like to give terms like "XX King", "walk about king", "Trinty" and such, but to me its all "action bola" only
There are good lenses in all brands and Pentax has had many very good ones over the 40+ years its been making cameras.
Then there are also the good 3rd party ones (ie. Voigtlander; Cosina; etc)
IMO, just look out for the good lenses that fit the budget and the demands/preference, rather than trying to chase such 'fluffy' names people dream up to 'up' their status.
My few cents
Thanks to all for weighing in ! Much appreciated. Although, I did fail to mention that a macro lens is a MUST (60% of my shoots will be macro)
But I have my heart on the smc PENTAX D FA MACRO 100mm F2.8 WR, almost bought it a week ago, even b4 purchasing the body
Eagerly awaiting Photokina with special interest in the possible K-5 replacement ! *fingers crossed*
I beileve every pentax lens is special so we dont need the holy trinity branding.
the closest we have is the FA princess and DA princess. you will have to fall in love with some of the lens then form your own trintiy.
