Got this for my GH4. I already had the 45-200mm but then I read that there was a similar lens with more pro glass, the Panasonic Lumix G X Vario PZ 45-175mm f/4.0-5.6 Zoom OIS Lens (Black). So, I returned the 45-200 and got the 45-175. So far, I like it.B&H is great on returns btw.

I had been using my GH4 with a Panasonic 14-45 mm manual zoom lens.  For telephoto shots I had adapted lenses from Pentax and Nikon film cameras.  This worked well but was never a fluid process and the film lenses were heavy.  When I decided to order the Panasonic Lumix G X Vario PZ 45-175mm lens it was backordered.  Reviews of this lens were mixed but mostly positive.  Some complained of a rattle and sent them back while others seemed to be satisfied.  When the backorder was lifted I decided to place an order and give it a try.  When my lens arrived it too had a rattle!  The loudest rattle was the dislodged lens cap and was of no consequence, but there was a second and less audible rattle that seemed to come from inside the lens.  This was concerning!  I mounted the lens and found it to operate as expected.  It zoomed, focused, and took sharp pictures at both the short and long focal lengths.  Consulting the internet and several camera forums it seemed that the rattle was due to the power O.I.S. system.  The rattle disappears when the power to the camera is turned on and returns when the power is off.  My Panasonic 14-45mm lens is also a power O.I.S. system lens and I had never noticed that it too exhibited the same characteristics.  I decided to keep the lens and have not been disappointed.  The lens is much lighter than either of the adapted lenses I had been using which is a big plus.  The internal zoom eliminates the extended tube that many zoom lenses exhibit.  In my opinion this lens is a keeper.

As a user of Nikon DSLR and mirrorless cameras I find my Panasonic Lumix GX8 and GX9 MFT cameras excellent for recording my kids' sports activities. I purchased the 45-175mm lens for the sports activities when my 12-60mm lens is too short of a focal range. So far I have found the zoom range of this lens to be what I need and the power zoom is smooth and fast enough for following action. I use it in well lighted settings so the aperture range is not a problem. For the price, quality, ease of use and to record my kids I made the correct decision to purchase this particular zoom.

This lens is very underrated. I find it to be very sharp, with excellent contrast. The OIS works great as well. It focuses extremely fast, and is so light and small, I carry it everywhere.

I suddenly had to find a power zoom lens for smooth zooming while recording video. I am very new to these types of cameras, know very little about lenses, and had very little time to figure something out. So I was very thankful that Panasonic now has a power zoom lens.

I read as much as I could about adapters, and other lenses - some which had better - but I needed to know absolutely that what I got fit my GH4 & would work immediately.

It did & was excellent - very smooth zoom, easy, easy, easy! Also the location of the zoom button is fairly convenient.

I was shooting outside first in blazing sun, then an hour later in heavy cloud cover. perfect for my use in both. I needed to zoom in on something the size of a soda bottle on a post 250 yards away.

Simple to use, and it worked right away. Major KUDDOS to B&H for getting this delivered a full day before it was due. I paid for the two day & it arrived early which gave me that 2nd day to get the video just in time.

Because it's a 45-175 (35mm Equivalent Focal Length: 90 to 350mm) it is not going to be as useful as my 14-140 is, but I am so glad I got this because the power zoom also holds the focus much better on manual focus. It's not parfocal, but much better than what I was trying to do with the other lens.

Also - Thank you B&H for having the filter with it. I'll update this if I have any changes when I have used it a little more - Now though, I really need to find a power zoom that is in that 14-140 range....

I bought this to put on a GH5 II because I needed a bit more zoom to get across our sanctuary than the 35-100mm I had been using. Wow - the first time I saw the image on the monitor I knew I had made the right choice. Sharp & beautiful. I've used it for video/livestreaming only so far, and on a tripod, but in those situations it totally delivers. Great price for what you get.
