planning to get this for an old lens. anyone used this before?

Also, is the confirmation chip a must? or I can just get the ones without the chip?

want to use this with Canon FL 50MM f1.4

You buying the adapter with glass or non glass type?

From my reading the confirmation chip is to communicate with camera so that you have AF confirmation in viewfinder. So if you think your eyesight is good to judge a focus photo then you dont need it.

all the adapters at least for what i want only comes with glass.

might get the fotodiox ones since they released a manual to remove the glass.

That way I can compare glass or no glass better for close shots. the glass is for infinity focus iinm

You might want to read up the adapter review before buying them because some of the glass on the adapter will degrade the image quality.
Just my 2 centz

yeah i've read some of them. they mention the glass will start to degrade as you focus towards infinity. not sure to get or not get. maybe i'll just upcar first lol
