Samyang 35 1.4 adds grain?

Samyang doesn't, it's all mechanical (good for Nikon :) ). IMHO, that chip isn't a must-have for that lens. It works for focus confirmation and adding some EXIF data like lens focal length or focus distance (I'm not sure about the last one), but you won't get any aperture information. I tried the focus confirmation with some lenses and it seems pretty useless for me. I think that MF screen is a better tool for that.

Thank you. Unfortunately I have (for the moment) decided not to buy the 1dx and am using the 5d3. Cant change screens on that!!!... :(

Well, MF screen seems to work great when shooting through the OVF, but I'm using LiveView for manual focusing. I think it's the most accurate tool for focus and exposure.

I think there is a seller on eBay that sells the Canon mount Samyang with a chip already installed.
Yes, I also wonder why Samyang doesn't install chips for their Canon mount lens since their Nikon mount has one. (I actually have a chipped Nikon mount lens and use a chipped adapter)
That said, you can just epoxy it to the chrome ring that fits the lens to the body, just place it so the contacts are the same place as where the contacts are on a Canon lens. Obviously they are small so correct placement is critical.

Did not know the Zeiss had electronic aperture, but then I'm a low budget kinda guy and don't keep up with Zeiss so much... ;)
I'm surprise you haven't had much luck focusing with the confirm chip, I've had good success and keeper rate is way up there. Another great focus aid for manual lenses is the Magic Lantern focus peaking in Live View if you have a body that can run ML.

I have the 8mm and it does this also, it isn't the lens, I'm pretty sure it's the focusing screen or some other element above the mirror.
