Zeiss Lens on Olympus E-P1? Oh Yeah!

The Olympus PEN E-P1 is a versatile camera that can accept Leica, Nikon, and Zeiss lenses with the right adapter. I have a small cache of Zeiss prime lenses in the Contax M mount that are part of my Contax RX kit. Since I don't shoot very much film these days, I've been looking for a way to put this wonderful glass to work. I read about the Novoflex Four Thirds adapters, but I could not find the Contax mount anywhere (the Leica version seems more plentiful here in the States).

The Search for a Contax Adapter

After scouring the Web for any adapter that would work, I found a great site called Japan Exposures that had all sorts of photographic exotica, including Rayqual Micro Four Thirds adapters for Contax M and Nikon F mounts. I purchased the Contax mount for 18,700 Yen, and they shipped it to me within a few days. I had a very good customer experience with them.

Mounting the Lens on the E-P1

The Rayqual mount is excellent. There's no wiggle at all. It's finely machined and has a solid feel. The first lens I tested on the E-P1 was the Zeiss 50mm f/1.7 MM. The set up is easy. You mount the adapter on the body, then attach the lens to the adapter. Everything clicks into place. There are no electronic contacts on the adapter, so you work in aperture priority mode. Focus with the lens wide open, then if you need too, stop down to make the exposure. The E-P1 sets the appropriate shutter speed for you. It worked great. If you have lots of light, then you can focus stopped down. Although I must admit, what I wanted to do was shoot wide open most of the time taking advantage of the unique qualities of the Zeiss Planar lens.

You can configure the E-P1 for manual focus-assist giving you 7X magnification with just a push of the OK button. I love this mode and use it to get the focus just right, then back off to normal view and take the picture. Focusing on the 3" LCD was easier than I expected. Working with the silky smooth focusing ring and the click-stop aperture ring on the Zeiss Planar provided a truly classic photographic experience.

Picture Quality

As far as picture quality, my favorite lens was the Zeiss Distagon 35mm f/2.8. The shots were beautiful at every aperture setting. Next, I also liked the 50mm f/1.7 and the 85mm f/2.8. They were a little softer on the edges than the 35mm, but still quite good. I was disappointed with both the Zeiss 135mm f/2.8 and 200mm f/3.5 telephotos. They weren't as sharp on the E-P1 as they are on the Contax bodies. It seemed to me that the E-P1 performs better with the wider and standard lenses than with the longer focal lengths. I will continue to test and report more on this.

Final Thoughts

Shooting with the Contax lenses on the Olympus E-P1 is a brand new experience. It's so unique, it's almost hard to describe. I'm once again focusing the camera myself, yet I have a big 3" LCD with digital focusing assist to provide a new twist on the process. The camera looks good with any of the Zeiss lenses mounted, and the shooting is outright fun. Most of the camera functions work just fine, including flash, image stabilization, and even movie mode. There are a few gaps in the metadata because the camera can't report aperture or focal length, but you get ISO, white balance, shutter speed, etc. The shots look different than with any other lens/camera combination.

For the time being, I'm going to work with these lenses on the E-P1 and see how it affects my photography. I'm already feeling more creative every time I pick it up. I'll publish a collection on our Flickr site soon.

On the Olympus the lens seems low-contrast, and ISO 1600 honestly doesn't bowl me over. Canikon does better above ISO 800.

Yesterday I saw this direct video comparison between the AF capture speed of an EP-1 and a Panasonic G1.


The G1 blew away the Olympus in regular daylight. And when you consider that the size of both cameras WITH LENSES ATTACHED isn't that different but the G1 has a more useful viewfinder to boot, I cannot see why people would choose the EP-1 aside from the 'cool factor.'


I am kelly Turner's (MacWorld) father-in-law, she recommended your site. Good advice. Regarding old lenses: I have a few Leica lenses and have been shooting with my 50mm Summicron on a new G1. I am very pleased with the results; both the imagine quality and the larger aperture which provides speed advantages ( I like to shoot below 800 for noise control) and pleasing depth of focus. I also find the effective focal length of 100 mm great for portraits. Not sure why, but few forms discuss this particular lens. Thought my experience might be on interest.

Hi Jeff,

I feel the same way about the Zeiss 50mm f/1.7 as you do the Leica. I've always liked the 100mm effective range, and now to have that at f/1.7 is terrific!

Hi Elliot, I just want to remind you that the sample shot here was taken in *very* low light. You need light for contrast...

Hi Derrick,

thanks a lot for this report, I have been looking at the E-P1 to use it with my valued Zeiss lenses, too, so I am glad to see the first test shots.

There might be another option for you to put this excellent glass to work: I use my Canon 5D with these Contax lenses almost exclusively (28/2.8 is my favourite), the results are unique and the photographic experience is "as it used to be" :-)

For those folks with Zeiss ZM or Leica M mount lenses who want to shoot with the E-P1 or Panasonic G1, Amazon U.S. sells the micro 4/3 to M adapter.

Elliot, the GH-1 costs twice as much as the E-P1.

Hello, thanks for this article I found it very interesting. I have just purchased an Olympus PEN EP1 and have also ordered the Novoflex adapter for M lenses (I have the 35mm and 50mm Summicron)

A question for you if I may?

When shooting is it best simply to use Aperture Priority mode or full manual mode? Are there any relative advantages to either approach? I imagine that Aperture Priority mode is better but how does the PEN know what Aperture is set to? (and therefore able to select the correct shutter speed?)

Many thanks

Hi Jason,

the PEN does not read out the lense's aperture, so you simply keep lense and camera at the same aperture setting (A-Mode).


Remember that you have a 2x cropping factor

Hi Mike,

I also have the EP-1 and some C/Y Zeiss lenses, including the Distagon 2.8/35 , using an adapter without eletronics.
Camera in Aperture priority and MF Assist is ON.
I don't know how to activate the magnification to help focusing. Can you kindly help?




I am having trouble to activate the MF Assist. It is ON but I don't know how to activate it.

You mention this was assigned to OK button. How to do it?



I figured out by accident: I needed to press INFO during live view until the small green square appears. Then OK activates the magnification.
