Overview Simply amazing lens. I am a professional photographer and videographer and I use this lens with my GH5 for video only. I have never taken a single picture with my GH5 so I cannot speak to the photography features of this lens, but for video it has exceeded my expectations. This lens provides buttery bokeh when used wide open, weather sealing when paired with the GH5, and fast auto focus. I use hybrid auto focus usually with this lens and occasionally manual focus if it is not properly pulling focus. Other Users Complains I read a few reviewers who were complaining about this lens because in their words "it is too zoomed in". Come on people you need to know how to read lens specifications before you buy a lens like this; this is not a wide angle lens and no I would not try to use this on a gimble or anything except a tripod. On a proper video tripod or even a stable monopod, you can properly stabilize this lens and focus on the scene vs. the stability. This is a 70-200mm full frame equivalent lens. My Experience I got this lens mainly to shoot events where you are usually too far away to get footage with a wider lens. This lens has proven great for events, for truly shallow depth of field when zoomed in and filming up close. For one shoot I used this lens dialed in at 100mm, the tele convert feature in the GH5, and was shooting at 4K so in post I was delivering to the customer 1080P so I was able to punch in again another 2x giving me crisp clear shallow DOF footage at almost 600mm FF equivalent! All with this tiny lens. The footage was nothing short of amazing. So if you need a GH5 lens that is great for events, super shallow DOF, weather sealed, and know what it takes to properly stabilize a 70-200mm FF equivalent lens, you will not be disappointed with this lens. Also autofocus works with this lens so you can save time by using hybrid AF like I do, and I love the focus transition feature of the GH5; I use it all the time in properly blocked scenes, but this only works if you use native lenses that support AF. Conclusion Just like my Canon 70-200mm lens for photography; this has become my go to lens when filming interviews (for the shallow DOF), events (for the long reach), and for the cinematic look (buttery bokeh). If you are looking for a lens to throw on your Crane or Ronin S, this is probably not the right lens, but if you have a good tripod with fluid video head and need an excellent lens with some reach, this is probably the best it gets for the GH5. Oh and if you are wedding videographer stop reading this right now and just buy this lens already, you can thank me later.
