If you hear the phrase “holy trinity” applied to photography, it means a selection of prime lenses with a wide, a standard, and a medium telephoto focal length. Depending on the type of photography you do, you may never need any other lens.
Olympus has just announced two new lenses that join the already shipping Olympus M.Zuiko Digital ED 25mm f/1.2 PRO Lens to form their new trinity.

I was one of the lucky fellows who received one of the pre-production models of the Olympus OM-D E-M1 X camera bodies. That was just about six months ago. I primarily ran tests with it the first six weeks I had it, partly because I had to keep it a secret that I had one. Once the camera was out in the wild, I began shooting with it almost exclusively, only using my Olympus OM-D E-M1 MK II as backup. Then, last month I traded in the MK II for a second Model X and that is all I use.
