Olympus 12-100mm F/4 IS PRO

The 12-100mm F/4 IS Pro feels great in the hands. The finish on the lens barrel is easy to hold onto and doesn’t feel like something that could easily slip out of your hand. The lens looks as if it could be a little front heavy on the very light Olympus cameras, especially when the barrel is fully extended.

The lens has a good size for anyone with average to large hands, it fits comfortably. Users with smaller hands may find the lens to be a bit on the large size to hold, but overall it is a good size.

Build Quality

The build quality of this lens is exactly what you would expect for a professional level lens from Olympus. It is incredibly solid and feels like a substantial lens, you can tell that there is a lot of glass in there.

The switches for the L-FN and Image Stabilization have a perfect amount of resistance, not so much so that they are hard to switch, but not so easy that you are constantly switching them by accident.

The lens does feature weather sealing, but given that we were just viewing the lens in a press meeting room we did not have a chance to test it.


TBD, We were not able to shoot any images with the lens this time around.

First Impressions

We really love these Olympus PRO lenses, the look, and the feel are as good as any other pro-level lens out there and this new 12-100mm F/4 is no different. The focus ring is smooth and very responsive. The zoom ring had a little more resistance that we prefer, but it wasn’t bad at all.

Overall though, the lens looks great, is very solidly built and seems like it will be a great addition to the Olympus M4/3 lens lineup. Stay tuned for our full review once we are able to get a review unit in.
