I've been gently looking into what constitutes a trinity of lenses in the u4/3 ecosystem and I'm not finding what I am looking for. Maybe I'm not looking hard enough. Most of the suggestions I see are to cover use cases like wide-normal-tele. A sample trinity of primes could be something like 12/14 for the wide, 20/25 for the normal, and 30/45 for the tele. It's very logical and complete. Something similar can be put together for zooms. The K-mount ecosystem has a widely accepted trinity consisting of the FA Limited lenses. Their focal lengths are 31mm, 43mm, and 77mm. All of these lengths are unconventional: wide but not too wide, normal but kind of wide-normal, and tele but not as tele as could be. Rather than defining this trinity by use case Pentaxians sometimes describe it by character. One of the most colorful and memorable I have read on the forums is the princess, the bitch, and the queen for the 31mm, 43mm, and 77mm. I couldn't agree more! The princess is produces sweet images with the greatest ease of the three. Depth of field is plentiful. Color is vivid and saturated. The princess plays games with you and makes you chase your images. Go here, go there! Too late! Keep chasing! You'll end up with a SD card full of joy at the end. The images are truly frozen frames of real life. You almost expect whatever you are looking at to suddenly become animated. It's typical Pentax rendering that looks like it was drawn by hand to stand out. The bitch is temperamental. Easy to flare and plenty of CA when provoked. Fails all the paper-target based lens online tests. The lens argues with you telling you what to do, when to do it, and how to do it. You resist at first and your images look awful. Finally, you submit and you are wonderfully rewarded with edgy rendering that makes you think twice about what you see. She's a bitch because she knows she can be. Pixel peep if you need to you. It'll just prove her right. The queen reigns supreme. Wickedly sharp when used nearly wide open, the lens can extract all sorts of detail, color, and tone you would never see with your own eyes. The queen represents the highest standard of dignity, honor, and integrity. She doesn't make a fuss and she gets it right the first time. After all, there's no time to waste in state matters. Just as Queen Elizabeth is quintessentially British, the 77mm is the penultimate Pentax lens. With all this in mind, what would the equivalent be in the u4/3 system? The only prime I have shot with is the Panasonic 20mm. My experience is very limited but it feels like a princess lens. Thanks!
