The G.Zuiko 40 is really quite sweet. The only problem is finding one and not paying too much for it. I paid too much for mine but I'm happy for it.
My bodged together adapter is something anyone can do. It's simply a micro-FourThirds astronomical telescope mount from Hutech ($43) plus the lens-mount portion of a set of Olympus Pen F extension rings. The only issue, really, is finding the extension ring set ... when you can find them, they cost about $90-100.
That said, both jinfinance and another vendor whose name escapes me says they'll be shipping Pen F to micro43 adapters right about now... :-)
As Honey Rabbit once said, "Spring is here."
DR 'cron. Lovin' this lens, Helen
My G1 should arrive on Saturday. I am anxious to try my Hexanon 50 1.2 (M mount) with it. I think this should be a wonderful combination although the lens is heavy and may make for an unstable platform. However I expect the file quality to be superb. We shall see. I'll post results
I have a Minolta MC 58/1.2 converted to f-mount and it is very heavy but feels fine on the G1. I cradle the combo with the lens in my hand--not sure how much weight the G1 can handle. The DR 'cron has some heft to it, but feels great actually. Even though the 50's come out to be 100mm on the G1, I like the focal length and use it often, more often than any other lens I have.
Enjoy and definitely share your results, especially wide open.
Although I cannot find the reference at present, I recall that I read in some Panasonic document or another that the recommended maximum weight lens you should use on the G1 when mounted via the tripod mounting screw on the body should be no more than 1 Kg (2.2 lbs).
This isn't an issue, of course, when you're hand-holding and supporting the camera/lens assembly by the lens, or for a lens mounted on a tripod with its own tripod mounting foot or fixture.
Sitting on the ground on the other side of the picket fence in the afternoon sun shooting a macro of a fiddlehead, I noticed this and pulled out the FD 50 f/1.8--shot at f/2.8==I tried several--open, stopped down, etc., but liked this softer feeling with the sun through the Japanese Maples.
My own seat-of-the-pants feeling is that my AF MicroNikkor 60/2.8 on its adapter is close to the maximum I feel comfortable hanging on the G1. But then, I seldom use a tripod (regrettably...).
The first 2 images here are with the 60/2.8, and the third with my ancient uncoated Summar 2/50, all wide open and handheld.

Here are some shots with Kern Macro-Switar 50mm f1.4 C-Mount.
Sharp and nice bokeh, i think. Covers sensor. All at f1.4 or f2.0 some at ISO 400.
You have to be careful as I tried few of them and here is what I have found:
Switar 50mm AR - needs machining.
Switar 50mm RX - focusing ring is too close to adapter.
Macro-Switar 50mm - ding, ding, ding, BINGO...
Kern-paillards are are amazing. (in particular 26mm f1.1, 50mm f1.4 Macro and 75mm f1.9)
I need some clarification. I just got my G1 and have been using the kit lenses on it. Now I am ready to use some of my M glass using John Milich's adapters. I thought I had read on these threads that the focus magnifier worked with alternate lenses i.e. when you rotate the focus ring on the lenses you automatically went into the 5X magnifier mode. On the two lenses I tried the 5X mag was not enabled by either. As I think about it more, since there is no electrical connection from the lens to the G1 body is doesn't seem likely that the camera knows that any focus action is taking place therefore the magnifier is not activated.
Could someone clue me in as to whether or not the focus magnifier works with alternate lenses? If not it is very disappointing as critical focus with lenses like the Nocti or the Hexanon 1.2 is part of why I bought the G1
Regardless let me know the real scoop here.
Put the focus dial on manual (left top of camera) (actually this is probably not necessary)
Press left arrow, then center button, to activate focus assist. Rotate the front wheel to step to higher mag.
After left arrow is pressed, the focus square can be moved to the desired location using the arrow keys; press center button to magnify.
Press shutter button halfway to go back to normal view.
After spending a couple months with the G1 and 50/1.4 I find critical focus is pretty easy and natural to achieve in most situations. Keep in mind that 4/3 has two stops more depth of field for any given aperture, so critical focus is easier anyhow.
Tip: Make sure you set the eye-level finder's diopter control very accurately for your vision. When the finder image is perfectly sharp, it's easier to distinguish between in-focus and not-quite-in-focus images without resorting to magnification.
Imagine a situation where you and a friend having a FF camera are standing side by side taking images of something. You use a 25mm lens and your friend has a 50mm lens so you are now framing the target (approx) the same way.
Let's say you find you need f/4 to get the DOF you think is the right for this image. If your friend now wants the same DOF he/she has to stop down to f/8. In other words, you get quite some DOF already at f/4 and focusing is less critical than it would be with the FF camera.
OTOH, if your friend figure f/2 would make for the right separation you would have to open up to f/1 to achieve the same result.
I hope that helps. (If you want to discuss it further I think you should start a new thread on the topic.) regards, /Jonas
I also find that I now can usually focus in many cases without using the MF assist. I checked myself on a number of occasions (focusing first without, then checking with MF assist) and found I was pretty spot on. For close up, I use MF assist.
Thanks Monza and Ranger 9 for the tip on using the focus assist. I am sure I will get much better images as a result of this
Some from the FD 50 f/1.8 today
I'm about done with flora for awhile I think.

Magnificent, Diane !
The third particularly, we would say a painting!
I also use my FD 50 f 1:8, but I did not arrive at a so beautiful result yet!
Sorry for my bad English....
Jonas, its less smooth than I'd like but mostly in the 3rd which I like for other reasons. This would be closer to what I'd prefer (maybe even more blurring than this)---done with selection and lens blur filter in PS (altho' I didn't take the time to use a gradient on the blur so the tulips looked 'pasted in' because the focal plane of the focused tulip--of the violas--became 'blurred' also-)
Perhaps the Hexanon 40 f/1.8 will have bokeh more to my liking in circumstances like this very busy background with very striking color contrasts--or maybe I would have gotten a smoother BG with it wide open--but it was a compromise--I did want a bit more DOF for the tulips and think I shot it about f/2.8--might even have been f/3.2. The others don't bother me much.
Thinking about it, I remembered I had a similar one to the 4th that I knew was wide open at f/1.8. The one above is probably at 2.8 (again, possibly even 3.2--I probably should keep a little notebook to write these down but often shoot same/similar at various apertures and focus points)--about a stop and a half. Maybe this is a better representation of the lens.
The compromise with this lens seems a bit difficult--it can be more or less reconciled with post processing, but for straight shooting one will have to consider a bit more DOF vs. (in some situations) perhaps a distracting bokeh.
I need to go back and find those 50 f/1.4 wide open shots of others--I looked at my 5D/50 f/1.4 but I almost never shoot it wide open but rather around f/2.8 because of its very very shallow DOF with FF.

Nice flowers Diane.
I need to get out too and take some shots with my new toys Cooke Ivotal 50mm f1.4 and Nokton 50mm f1.5. (pics soon)
Since some time I have sort of maintained a thread called "'Admirable' blur" over at FM Forums (Alternative gear forum) and I have slowly learned that there are quite some who really like the edgy and harsh bokeh from some lenses. I'm a lot more in favour for soft and creamy.
If it hadn't been the total opposite of what I think the µ4/3 should be I would by a Sigma 50/1.4 EX for my G1:
(Yes, I know, I took them using a Canon camera, sorry.)
The "better representation" image is totally crazy (to me)! I don't dislike it at all. But, to be honest, when I first looked at it I was impressed by the background and thought that was the wild and sketchy target. Then I saw the in focus flowers a bit down.
The Hexanon 40/1.8 is unknown to me but I think I have seen quite nice images taken with it.
I'm also looking forward to photomorgana's images. The CV50/1.5 is a 50mm lens I'm interested in but I would like to see more from it, and how it draws complicated backgrounds. I think your colorful flowers is a tricky situation for most lenses.
that is very impressive bokeh. I like creamy as well.
Just today saw these little beauties is my garden. The light was just right to catch them with my Canon FD 50mm f/1.4
The bright rings and hard edges seen at some places are in no way a show stopper. Together with the images ranger9 posted earlier I think this does it.
Thanks again, /Jonas
Here are a few shots with Cooke Ivotal Anastigmat 50mm f1.4 C-Mount.
I like it, I think I know now why this lens gets converted to Leica M-Mount.
Shot #3 is at f8 the rest at f1.4
Here are similar shots with Kern Macro-Switar 50mm f1.4
Disregard the sharpness, the wind was very strong, so focus is off on some of them, but bokeh still can be judged.
Shot #3 at f8 the rest at f1.4
Here are some with Voigtlandar Nokton 50mm f1.5
Shot #3 at f8 the rest at f2
I think its not bad of a bokeh.
These are samples for Summicron 40mm f2.0 (almost 50
pics 3 and 5 shot at f8 the rest at f2
Im not very happy how bokeh looks in difficult background situations.
But f8 is pretty good I think.

Brief reminder about bokeh: All other things being equal, you can't have "smooth" bokeh both in front of and behind the focus plane; you can have "edgy" bokeh in front and "smooth" bokeh behind, or vice-versa, but not both.
[Don't believe me? Read Section 2 of this; mind you, the guy who wrote it is merely a lens designer for Nikon, so you can't expect him to know as much as the experts who post on Internet photo forums ;-) ]
Anyway, having the smooth bokeh behind the subject makes more sense for carefully-composed flower pictures, portraits, etc., where you probably want to subdue distracting backgrounds.
But for documentary-style shooting, where it may be impossible to avoid having objects between the camera and the subject, it actually may make more sense to have the smooth bokeh in the front -- where it can help make these intruding objects less distracting.
So, how the lens is designed with regard to "bokeh distribution" may depend in part on the designer's assumptions on how the lens will be used!
G1 & Cron 50
I take the risk of sounding very stupid, what's Cron ???
E-M1/GH2/G1 Full Spectrum & lots of lenses
That is a very nice natural portrait .
Thanks for showing . I will try to do something similar with my KONICA HEXAR 2,8/50 .
I think cron stands for SUMMICRON (Leica Lens)
Indeed, 50mm f2 Leitz. Not the fastest but a superb performing lens both on M8 being (60+mm effective) and on the G1 (effective 100mm short tele)
And in b/w I find it amazing, although I am not able to do the beautiful conversions some folks show on this site :-(
Noctilux = f/0.95-f/1.2,
Summilux = f/1.4,
Summicron = f/2,
Summarit = f/2.5,
Elmarit = f/2.8,
Elmar = f/3.5-f/4.
Noct, Lux and Cron are referred as short forms for Noctilux, Summilux and Summicron, respectively. Thus, 50 Cron uniquely identifies Summicron-M 50mm f/2 irrespective the date of manufacture, although for every lens there are countless (sub)versions. just too long history :-)
