I have a G1 and I'm very pleased with it. OK, it's an electronic eye-level viewfinder but it's quite adequate. Also I use many of my old manual focus lens. Actually it's the only digital camera that I can use my old Canon FD lenses on. I've not experienced any problem manually focussing the old lenses. I guess that we are all different. As there is no moving mirror I find that I can handhold with quite slow shutter speeds.

... But it is not sharp enough for me to manually focus my vintage lenses on the G1 ... With an electronic viewfinder you're certainly looking through the lens, but is that kind of viewfinder really intended to be a focus aid? Or just composing? Autofocus aside, the only focus aids ever offered on a compact camera, right back to the Leica II, were rangefinders, built-in or separate, and failing that, manually setting the focus scale on the lens after guessing. |

Thanks for that URL Dave. I'd be cautious about using an adaptor with a compensating lens. When I dabbled with Minolta AF SLRs I tried an adaptor to use Minolta MD/MC lenses and that had a compensating lens. Results were not good. There is a good selection of adaptors listed at that site. |

Just one other point about manual focussing with the G1 is that it has a function built in to enlarge an area of the frame to enable fine focussing.

Rachel, I just plucked that one out as an example, but it is interesting to hear comments on them. It's never easy to find good practical information on such as lens adapters. Do you actually need the compensating lens version - the one without is cheaper. What is it for anyway? I can come up with a few answers myself, but need to look further before I finally buy. Any advice is welcome.
The FZ20 has that aid too. I have very occasionally used it, but, like Bob, I do prefer a proper viewfinder.
Dave.

Dave, I believe that the glass element in the adapters is to preserve the ability to focus to infinity. Without the glass element, many adapters are too thick to allow the adapted lens to attain the required register distance to focus to infinity. The lens then will only function as a quasi-macro lens. On other forums, the opinion of the optical adapter is virtually universally negative. This is the same issue that exists with the inexpensive flanged (available all over E-Bay) M42 to Kmount adapters.

Roy, I thought the focus to infinity was the most likely reason. Some "add-ons", even those that are cheap, are very good while others, many expensive, aren't worth a bean. I suppose in the end it's a case of buying one and seeing if it is as good as hoped or as bad as some might say. Thanks.
Dave.
