Panasonic Lumix G1 with Leica Summicron 90mm f/2 lens

Panasonic Lumix G1 with Leica Summicron 90mm f/2 lens

The Summicron 9omm f/2 is one of the finest lenses that Leica makes.  On a film M-series camera it’s a longish portrait lens. On the digital M8 with its 1.3 crop factor its still a longish portrait lens.  On the G1 with its 2x crop factor, it’s a full blown medium telephoto lens with the ability to focus down to less than one meter.  And a fast f/2 lens.


The lens has great bokeh and pretty good contrast, making it ideal to isolate the subject from the background.  On the G1, this lens is a very good performer, creating images that would rival those created by the M8.  Of course its the lens that makes the major contribution.

Poor off-center resolution as seen in some images created by particular wide-angle lenses is non-existent.  It had been speculated at some of the Leica-centric forums that this resolution issue was caused by the particular angle of light refraction through Leica M-mount lenses and that this would be less of an issue with longer focal length lenses.


The 90mm is still a handful on the G1 as its effectively an 180mm lens without the advantage of image stabilization.  Keeping your shutter speed at or above  1/250 sec to insure a decent handheld image.

  1. about what vintage/version is the 90mm F2 Leica lens you used for this? Also, does the M bayonet mount attach the lens seamlessly?

    • John,

      I have the 4th generation Summicron. Re your other question, there is no problem attaching almost any M mount lens to the G1, provided you have an adaptor such as the Rayqual.

  3. Hi,

    This lens is not the APO version right? I’m thinking of getting one to use with my GF1 but having doubts about the weight. Does it feel heavy/hard to handle with your G1?

    • This lens is the APO version. I don’t find it that heavy although it is a bit dense. The balance between the body and lens is good with the lens naturally resting in the palm.
