From The Photoblographer:
The folks over at 43rumors have received word that Olympus might be coming up with a new prime lens for Micro Four Thirds–a 25mm f1.8, to be exact. It is also said that the lens will be launched alongside the low-end OM-D camera that Olympus is currently working on. The camera was previously reported to be launched just ahead of the CP+ show in Tokyo, which will take place in February.
If this report turns out to be correct, the lens would nicely fill the gap between the already available 17mm f1.8 and 45mm f1.8 lenses. Those three would make a lovely prime lens set featuring the classic focal lengths of 35mm, 50mm, and 90mm. Also, this wouldn’t be the first 25mm prime lens from Olympus. For its Four Thirds DSLR cameras, the company made a 25mm f2.8 pancake lens.
43rumors also states that the 25mm f1.8 will be smaller and cheaper than the Panasonic Leica 25mm f1.4, which only makes sense if Olympus actually wants to sell it. It is said to be slightly larger than the Panasonic 20mm f1.7, though, which means it won’t be a pancake lens. As always, these are only reports so far, and we don’t have confirmation on any of the details yet.
