Question about adapters. I bought a Canon to M4/3s on Ebay. It is very solid and seems nice, but has a built in aperture ring that only goes down to 2.8. I got it to use with my 1.4 lenses...did I just get screwed?
I assume you're referring to a Canon EF/EOS adapter with the built in aperture ring, correct? Most of these that I have seen don't actually have f/number markings (the ring is just marked with a 1 to 6 or something). I would be a bit dubious of any adapter that purports to tell you the f/stop, since this is a ratio of focal length to aperture diameter and the adapter does not know the focal length of the lens you have mounted. Here's one that's marked to f/1.7, but I doubt it actually has a larger maximum aperture diameter than the adapter you have.Question about adapters. I bought a Canon to M4/3s on Ebay.

This is true, and it's basically stated in the original post although in a slightly different way. Twisting the adapter ring moves the lens' aperture lever which stops down the lens. As far as I can tell the lens' breech lock is what really mounts the lens, so labeling this ring "Open/Lock" is a bit confusing. For myself I occasionally use this ring if I want to set critical focus while shooting with the lens stopped down...I'll turn the ring to "Open" and nail focus with the aperture wide open, then turn it back to "Lock" before I press the shutter.I have found with the Canon FD lens adapter that apart from using the open/lock switch to mount on the camera (G5 in my case), if this is left at LOCK as you suggest, it locks the aperture wide open and whatever aperture you set on the lens nothing changes...shutter speed or anything. However, when you set it to OPEN, all apertures can be selected. So it is not really for mounting the lens.
My understanding is that the "A" setting on an aperture ring would allow the native body to control the aperture. When adapted, the "A" setting essentially sets the lens wide open -- I can see no reason why you'd want to use it.Also....can anyone tell ne what the little green A is for after the f22 aperture on the lens ring? I have tried this setting using the little black button next to it but can't seem to see anything.
This is true of the Panasonic bodies. The Olympus bodies generally have a "magnify" button that achieves the same purpose.Have also notiiced that when focusing, you can press the thumb wheel to get a nice big magnification although it doesn't work by just turning focus ring on lens like the Panny lenses as no electronics etc.
Very much looking forward to using some legacy OM Zuiko glass with the E-PL3. Manual focus holds no fear for me. I'm interested, though, to know how aperture is dealt with if I'm shooting in aperture priority mode, which I'm led to believe will work as normal.
I ordered one from ebay and works fantastic.Anyone have any experience with those cheap ebay OM to m4/3 adapters?
Price is around 10$, and i know i should aim for more expensive ones (price=quality in this case), but it's hard to resist without actually knowing whats the problem with them...
