Lens configuration: 14 elements in 9 groups with 1 aspherical glass, 2 aspherical ED, 1 DSA lens, and 2 ED lens elements Colour rendition - For me this is really the most important factor, it simply takes the most gorgeous images. Seeing is believing. I have and use the 12-100, but not as a GP lens. For ME, the 12-100 is just a bit too heavy and big, to lug around all day. So it has become a task lens, I grab it for specific shoots based on the needs of that shoot.

Yes, the PRO zoom is the better lens (it's my most used lens for a reason); but try cropping to anything like a 1/9 of the image circle and examine what it can achieve ...The 72mm Sensei LHR2-T72 3-In-1 Rubber Lens Hood is designed to keep stray light out of the lens and reduce lens flare.

Overall, other than vignetting (see below), it pays to use this lens at f/4, where I'd judge it to be pretty darned good other than the extreme edges at the extreme focal lengths. With very few exceptions, this lens performs better at larger apertures than smaller. Keep it in the f/4 and f/5.6 aperture range and I think you'll be pleased with its optical performance. Up until recently, none of Olympus’ lenses incorporated optical stabilisation because most Olympus cameras include some form of in-body stabilisation. All this changed with the release of the M.Zuiko 300mm f/4 PRO whose optical stabilisation, dubbed Sync IS, can be used in conjunction with the in-body stabilisation of the E-M1, E-M5 II, Pen F and E-M1 II. Of course, many buyers will balk at the idea of paying a four-figure sum for a superzoom. But this one really can do it all unexpectedly well, and potentially replace a two or three other lenses in your bag. It’s a great addition to any Micro Four Thirds shooter’s arsenal.The folding hood allows you to easily store it in your camera bag while still attaching it to your lens. I have the PL 12-60 and e-M1ii and I love it. This lens changed my approach to photography and lured me into this expensive hobby.
