I also have been doing a lot of event coverage shooting lately. Do read up my tips on how to shoot an event here on MT’s site. The main lens I have been using for my jobs is the 25mm F1.8 lens. Upgrading to F1.2 PRO allows me more flexibility when it comes to low light shooting, I have about one stop advantage, which means I can effectively lower my ISO and produce cleaner images. This is applicable to both flash use and shoots with entirely avaiable light, the F1.2 wide open is a significant advantage in less than ideal lighting circumstances. The fact that Micro Four Thirds has 2 times equivalent depth of field, the F1.2 lens is perfectly usable rendering sufficient depth of field for most of my shots. I can use it at fully wide open F1.2 without stopping down, getting enough zone in focus and super sharp results at the same time.
Some users complained that the F1,2 PRO lenses are huge. Yes they are much larger than the F1.8 lenses, I agree with that. However, in terms of handling, I felt they were perfectly balanced on the E-M1 Mark II (I cannot say for smaller PEN cameras). It was as if I was using the M.Zuiko 12-40mm F2.8 PRO lens, which was perfect in terms of handling with the OM-D E-M1 series camera. The F1.2 advantage is huge, and having slight size and weight penalty, I am totally ok with the compromise.
Anyone else using the Olympus M.Zuiko 25mm F1.2 PRO lens? Do let me know your thoughts!
