Review - Samyang (Rokinon) 50mm f/1.2 AS UMC

[hacra]

Have you ever tried to use a dandelion chip?

In my rokinon/samyang 16mm i have attached a dandelion IV canon chip and works quite well with my 1Dx.

You can program it in a way that the files will retain the F stop used.

its also quite inexpensive (+/- 20 USD). While the AF confirm is a bit wide (i think it can be adjusted somehow) it does work quite ok.

here is a link to some of the parameters it can be programmed.

Had no problems with it, and might be the solution to your problem. It does take some adjusting of the position so that the camera detects the chip but once thats done, it just works.

This being said, i hope in the future rokinon included such a chip in the lens itself.

Not sure the same chip exists for other camera systems, but it somehow solved my problem.

I've used one for full frame mounts (M42 adapters and added one to a Rokinon 14mm f/2.8). I've not seen one for mirrorless lenses, however. I don't know that the EF-M mount has been popular enough to get much attention. It's somewhat ironic to me that Samyang IS producing AE versions of some of their lenses (with electronics), but is still releasing new lenses without them. I don't mind manual focus, but I do miss what the electronics can add otherwise.

Dear Friend Mr. hacra.
How can you mount this dandelion chip and control the Manual Focus Lens of Rokinon for EF-M mount ?
No Power point on Rokinon Lens at all.
Thanks.

No, you can't control the aperture or focus with a chip. What you can do is get electronic communication and program in the focal length as well as calibrate the focus confirm chip so that the appropriate focus point in the viewfinder will light up when the lens is in focus.

Thank you Sir, Dear great teacher Mr. Dustin.
Now, I am understand 100%.

Dear Mr Sir von Surapon!

I just want to make sure that you and other readers understand that the Dandelion chips won't work with EF-M lenses. Only with EF/EF-S such. The latter will report to your M camera thru an wired EF to EF-M adapter thou. You also need an EF camera to program them, that can't be done on a M.

With the most Sincerely and Honorably Regards
