hi all,
just got my first non-native lens. it's a helios 44m and i'm using a cheap chinese nikon-eos adapter (jinfinance). it works ok in movie mode. i can set the aperture manually on the lens and iso and exp comp appear to work fine on the camera. my problem is with still shooting--it doesn't work, i push the shutter and get an "err 01" (camera and contacts need checking, etc...) can anybody shed some light on this? do i have a bad adapter or is this a known limitation? thanks!

Sounds like either a bad adapter, or some sort of incompatibility; either mask adapter's contacts with something (nail polish? I didn't try), or unscrew the lens a bit, or remove the chip from the adapter. You will lose focus confirmation outside LiveView.
 
The cheap adapters don't have electronics; make sure you're shooting stills in manual mode, and don't trust the LCD to set exposure; take a test shot and then dial in your exposure visually or with the histogram. The adapter messes with the camera's usual way of exposing (DSLRs keep their lenses wide open until you hit the shutter release, and the electronics compute exposure based on knowing which stop you've selected - that all goes to hell shooting stills in my experience).
 
If you have an adapter without electronics, you shouldn't get strange errors like ERR01.

You can shoot stills in Av without problems, and in that case you can rely on LCD for exposure. In manual mode there's a bug: camera remembers some kind of EV correction factor from the previous chipped lens (workaround: shoot in Movie mode).

On 550D you can bypass this bug by removing the chipped lens while camera is still on... on 60D this trick doesn't work.
 
so i followed the advice on this board (esp a1ex) and did test the lens in different shooting modes. i got the problem in m,p,av--you name it. so i took a quick look at the inside adapter surface. the "sensor" / chip is poorly glued on to the adapter inside. i noticed that there was no "lock" to the bayonet mount. i.e. i could simply twist off the lens without pushing the release button. i twisted the lens a little until i heard a click and voila--the camera can take pics. i guess the sensor was not properly aligned to the pins inside the camera b/c of poor the adapter is cheap. this is not ideal, but i guess i can live with it. hope this helps someone else. thanks again everybody for the input!
