It totally sucks that we have to buy this in the first place, but whatever, we saved lots of money by purchasing a Samyang lens to begin with. It just worked flawlessly updating my Samyang 35mm F1.8 Sony e-mount lens on my 16-inch, 2021 MacBook Pro running MacOS 14.4.

solo lo use una vez, quise volverlo a usar y de la nada no funciono, agrego hice cambios de varios cables y nada

Funciona bien, pero ojalá no fuera necesario comprarla. Además es una tristeza que use cable micro usb.

Kudos to Samyang/Rokinon for continuing support on their lenses. This dock works as advertised.

REVIEWNot too much to say, as it's a very simple, straightforward product. Works exactly the same as the Sigma Lens Dock. The lens clicks in just like it does on the camera body. You can update firmware with it on all compatible lenses, along with autofocus fine tuning if your lens is slightly front/back focusing, and manual focus ring speed. Some lenses with custom switches or buttons allow you to modify those as well.Some newer lenses even allow autofocus fine tuning at multiple distances, exceeding most DSLRs, and matching what Sigma has available for their lenses. In general, this usually isn't needed on mirrorless, though, as mirrorless does not have the same kind of focus issues DSLRs had. Something to note is that some lenses do come autofocus tuned from the factory, not always perfectly. My 18/2.8 was set at -2 from the factory, but is sharper under the focus point when zeroed out. My 35/2.8 was at -3, but seems to focus fine like that.The matching software, Samyang Lens Manager, has a clean and simple layout that's easy to use, and only lags right in the beginning when connecting a lens. Otherwise, no complaints. Here's how to use it:FIRMWARE UIPDATE PROCEDURE1. Attach the Lens Station to USB, then to the lens2. Open the Lens Manager software3. Click the Lens Conn. button on the rightThe Lens Station will connect to the Lens Manager software. Usually, the software will identify if your firmware is out of date and simplify the update process to a series of OK buttons. But if it doesn't, here are the next steps:4. Click the Firmware Update icon5. Click on Download Link on the bottom6. Find your lens' firmware and download it, remembering the filename and location7. Click on Load Lens F/W File, find the firmware you just downloaded and open it8. Click on Update and follow the on-screen promptsAnd you're done! It'll take a little while to upload the firmware file, but you'll be notified when it's done. Finally, go back to Lens Connection icon and press the Disconnect button to disconnect the lens. You can attach another lens at this point and update its firmware starting with step 3, or close the software.BRICKED LENSESWhat sometimes happens is, while writing the firmware to the lens, the software or your computer's hardware will drop the connection. When this happens, the new firmware isn't completely written, and the lens won't work properly or at all when attached the camera. Most of the time, the lens will not reconnect to the software, either. Bricked! But don't panic!>>>>>>>>>>>>> THE SOLUTION (for 95% of cases, at least...) Seems like Samyang knew this might occur, so they allow you to update a lens' firmware without the software knowing what specific lens is attached. Do the normal steps 1 and 2 to attach the lens and start the software. But skip step 3. Instead, continue with step 4 through 8. The software should allow you to upload the firmware to the lens in a normal fashion despite not knowing which lens it is. This should return your lens to normal, along with upgrading the firmware at the same time.IMPORTANT: make sure you choose the right firmware from Samyang's Firmware download page. It's probably not terrible if you load the wrong one into the lens, as things seem recoverable even if incomplete/damaged firmware is present, but why take a chance.Hope this helps!

It works well but the software is not as user friendly as it should be, but the instructions are actually quite good. I have not received a warranty slip with any of the Samyang products I have purchased which is annoying. They came with a quality slip, whatever that is. However I contacted Samyang ( elite brands ) and was told there was a one year warranty. The lenses are quite sharp, inexpensive, small and an incredible value....it is my understanding that one must purchase this lens station for firmware updates...other lenses can do this on the camera.
