I bought the 1.4mm teleconverter for the new Leica 50-200mm f2.8-4.0 lens from Panasonic. I haven't found this teleconverter at any photo stores in the USA. I ordered it on ebay, shipping from Japan. I received it in four days. Shipping was free, and it has worked perfectly. With the TC on my 50-200, I extend my 400mm (35 equivalent) to 560mm. This is less than the 800mm (35 equivalent) with my 100-400mm lens, but it's just as sharp and much smaller and lighter. I can definitely recommend this teleconverter for the new 50-200mm lens.

I use the STC 14 with Lumix S Pro 70-200 f/2.8 and a Leica SL2 body. Works well, very sharp. I am pleased. NO lens update is required.
Excellent product. Hard to find - not in USA. Works well with the PL50-200 lens. Excellent in all respects, but very expensive accessary for use with only one lens. It is excellent, works well, and very sharp. Whether it is good value for the money is up to the individual photographer and how it is intended to be used. If the photographer does not have at least one of the two lenses (PL50-200 or PL200 f2.8) it is of no value. Used with those two lenses, it is amazing.
Acquired to use with my 70-200mm f/4 on an SL, a superb lens on its own, this teleconverter noticeably impacts image quality. Fine details lack acuity, and contrasting edges in details are fuzzy in uncorrected raw files. Contrast takes a hit as well.On the bright side, focus acquisition is fast and accurate on the SL. Judicious post-processing produces usable images.But overall, it's no better than some of the teleconverters made in the '80's and '90's. In 2020 one would expect better. A fine lens like the 70-200mm Lumix S Pro deserves better, especially when the manufacturer promotes the teleconverter as enabling 400mm reach.
If you are using this teleconverter on a Leica CL, you will need to download the lens firmware update (S-R70200V011.zip) from the Panasonic website and load it into the camera/lens without the teleconverter in the stack. Once you do the update, Lens Firmware ver 1.1 will show in the menu, and the stack will work with ver 3.1 of Leica CL firmware. The max aperture becomes 5.6; OIS works fine; AF works fine. No comment on IQ as I have not had time to take photos with the lens and tc, yet, but I wanted to post this for any other unsuspecting Leica CL L-mount users who mount the stack and are left holding a non-functioning camera.
Part 3 of my review: the 1.4 TC works very well with new Leica SL2. I’m seeing Much better IQ (resolution) than with the Leica CL for obvious reasons.
Have had it for two weeks. Using it with my Lumix 50-200mm lens. Shots below from Lone Star Le Mans race. Sharp, fast. Worth every penny.
Stacked with the new Lumix S Pro 70-200 f4 (the only compatible lens for now), this piece offers the equivalent reach of a 147-420 mm on my Leica CL.I think I see a slight drop off in sharpness, but this is expected and not a comment on the quality of the piece. This impression is based on looking at images. I did not do formal comparisons with a fixed subject using the lens with and without the TC.I hope to switch to the Leica SL2, soon, with which I expect significant improvement in IQ/sharpness with 280 mm reach. I think this stack will be a reasonable and much less expensive tele-zoom for the SL2 than the Leica equivalent (90-280), which costs over $6K. I've used the Leica 90-280. It is a fabulous lens, but it is a beast to handle (4.1 pounds versus 2.83 for ... MoreStacked with the new Lumix S Pro 70-200 f4 (the only compatible lens for now), this piece offers the equivalent reach of a 147-420 mm on my Leica CL.I think I see a slight drop off in sharpness, but this is expected and not a comment on the quality of the piece.

This stack is fairly compact and easy to handle when I am out birding.The AF works well, but only after you download the lens firmware update from the Panasonic website. Without the firmware update, the lens and TC will not be read by the camera; and AF and IS will not function. I had to figure this out on my own. The info sheet is useless.The image below is a slight crop (approx 80%). The lens was at 258 mm (equivalent of 387 mm in the APS-C sensor in the CL) according to the metadata.
