I purchased this lens actually to use in model photography in order to provide more background area than what I was normally getting with my 50mm. Used this lens extensively for the first time a few days ago. Very pleased with the images. I can easily foresee this lens being well used.

Great Product and Great Service

I had my eye on the Olympus 17mm lens for some time, but I was able to fit the Leica 15mm into my budget. I couldn’t be more pleased. The build quality is fantastic, and the included hood (metal) was a very nice touch. It’s not a pancake lens, but it is very small. I plan on using this as my “standard” walking around lens on my G9 and its G7 backup. Of course, B&H threw in a nice lens care kit. I’ve never been more pleased with a vendor than B&H.

It is tiny, well built, super sharp(even wide open), great colors...what else could you want. I had the DJI branded version of this previously (same lens, just branded with DJI name and packaged with zenmuse x5 drone camera) and used that for several years with my Olympus em5 mark ii. Loved that lens. However, the DJI version doesn't autofocus properly with cameras like the Olympus em1 mark ii and em5 Mark III that have phase detect autofocus (when shooting in c-af) so I had to sell that lens and purchase the Panasonic version. Love it. Focuses insanely fast and precise on my new em5 Mark III and makes lovely images. Highly recommend.

Perfect lens when I am walking around. Love my Leica cameras, but this lens on the DC-G9 is just an enjoyable experience. Never get into the technical side of things, I just enjoy shooting photos.

It should cost more, but don't tell anyone

We generally pay too much for what really pleases us, but this jewel made a big impression on me. It feels, smells, and runs as the F1 of lenses. I compared with the Lumix DC-GX9 for my sketch pad camera and it gives so much joy that some of the photos have become my favorites, especially because I use it in manual mode but just in case for street photography to keep it in my coat pocket—the auto focus is very handy. I often use ND filters and it is very difficult to use the original lens shade so I placed the filter on the Artisan 46 vented hood and now it is a perfect match.

question

Other than the fact that it can be open as wide as f1.7 is the IQ, let's say around 5.6-16, which is what is most of the time used for landscapes much better than what the kit lens 14-42 delivers? In other words, inside a building it's going to be great to have 1.7, but to film a big field with horses with mountains in the background in broad daylight, how much better is it going to be than the kit lens?
Asked by: Philippe
If you shoot both lenses at the same f/stop, say f/5.6, and then look critically, the Leica DG Summilux 15mm prime lens will be better for two reasons:1.It is a prime lens. By its nature of being a lens with fewer glass elements, it will have superior sharpness, contrast and color as well as more pronounced bokeh and smaller size. 2.The build quality of the Lumix G Vario 14-42mm is good but the build quality of the Leica DG Summilux 15mm is better. A closer comparison would be the Leica DG Summilux 15mm vs the Panasonic Lumix G X Vario 12-35mm f/2.8 II ASPH. POWER O.I.S. Lens B&H # PA123528A. There the image quality difference is less and the consideration comes down to do you want the mm focal range convenience of the zoom or the increased bokeh and smaller size of the prime lens. For landscapes, I would definitely prefer the Leica DG Summilux 15mm over the Lumix G Vario 14-42mm.

question

I'm having a hard time finding a follow focus ring that works with this lens as it is so small the focus ring sits under the little hood that comes out on top of the Gh4. Anyone else find a good solution to add a follow focus ring to this lens on a Gh4? Any help would be much appreciated.
Asked by: James
You might try the Zacuto Z-ZG-16 ZipGear, as it has a lower profile than other gear rings. Then for a follow focus, you could look at the Redrock Micro microFollowFocus Black. It has a flippable gear box, which would allow it to connect to a focus ring that is closer to a camera body.

this would be an excellent lens for video on the GH4 and would have no effect over your ability to use variable frame rate.
