I'll start by asking what infinity focus is. Besides the obvious, does it mean that if I set the focus dial on the lens to infinity, it really is focusing to infinity.

My experience with a Minolta AF adapter and a 50mm lens proved that the adapter I purchased was not very accurate. I would actually hit infinity focus before it reached the end on the dial.

Now with this MC/MD adapter, it is much closer to the end of the focus dial, but still not exact. What gives? Do I need to buy an ultra expensive adapter for it to be exact or are they all like this? I am currently using a Japanese model from Roxsen which I purchased on Ebay.

Just curious what others have experienced with these adapters or others.

Hi,

I too use Minolta MDs with an adapter that was about 70 Euros. Here it is.

And as with yours I reach infinity focus just before the end of the dial but I don´t find it difficult to adjust my dialing accordingly.

The real good ones would be those from novoflex here.

But having just shot 10 days straight with the cheapo one I don´t think the novoflex is neccessary.

Regards!
 
Thanks for the response.

The adapter I have looks very similar to yours. I'm familiar with Novoflex, just not ready to spend $235 for a piece of metal.

There are some applications where it's nice to set the dial to infinity and know that the focus is correct without having to make sure.
 
I have 3 adapter for my GH1... a Minolta MC, M42 and Olympus OM, all of them focus just after infinity, you just have to focus all the way to the end of the focus dial, and turn back just a little.
