Cannon does not say what error codes above code 02 mean. They only suggest the costumer to make contact with the nearest Canon service centre. But connecting a non autofocus lens from an other brand, could be something the camera can't cope with. And the most Canon (and other brand) camera's can't focus when a lens has a aperture greater than f/1: 5,6. The f/1: 6,3 or perhaps even f/1: 8 is one or two stops to much for your camera. Special when you try to use this lens in no bright places.

Are you trying to waste people's time here, or what? Rokinon lens, Nikon mount, then mixing that with a Canon EOS 350D???

This will have to be sent in for repair, no other way around it. Call a camera repair facility first before you send it in to get a quote, many times a new or used lens is cheeper. Don't forget to check Ebay. Good-luck

The Rokinon lens lacks the electronics to communicate with the camera. You need to set the camera to the Manual exposure mode. Since the mirror lens also lacks an aperture control, you will need to control the exposure by changing the shutter speed and/or the ISO setting. Also, depending on the model of your Nikon, you may or may not get any exposure assistance from the camera's light meter. If you don't, you can use the image review on the LCD and the histogram to tune your exposure.

For the Rokinon 500mm F/6.3 lens, you can either attach 95mm filters to the front or 34mm filters to the rear of the lens.

For the Rokinon 500mm F/8 lens, you can only attach 30.5mm filters to the rear of the lens.

To attach a filter to the rear of the lens, remove the lens from the camera (or take the rear lens cap off). There's a threaded screw mount just inside of where the lens fits onto the camera. Take your filter and screw it into place. Hand tighten until it's snug and doesn't project in the way---remember, you're going to want to take it off again later.

The 30.5mm rear filters fit in the rear of the lens. If you remove the T-mount adapter, you should see the threads which take the filter.

Change the Input on the TV. Like from HDMI 1 to HDMI 2 for example. Or to component video. Trace the wire from your cable /satellite receiver and see where it's plugged into the TV then select that input.

The lens does not have the electronics to communicate with the camera. It will work fine in Manual exposure mode. Turn the mode dial to M. You'll have to set the shutter speed yourself, without any help from the camera's exposure meter. You'll also have to focus yourself, of course.

It is possible you may have purchased an adapter that does NOT function in "auto-focus" and if you have an auto-focus lens, the electronic connections between the two may not be compatible. This may be causing that problem.
