Panasonic GM1 First Thoughts – part 2

In my previous post I looked at the size of the GM1 in comparison to the LX7. In this post I will look at my thoughts around image quality. Right up front I should say that this camera is in another league when compared to the LX7, but then you would expect it to be. And to be entirely fair to the LX7, I have been producing some very detailed and high quality A2 prints from it recently.

In the following image you can see a shot of cracked paintwork which was captured on the GM1 with the 12-32mm kit lens at 18mm with the ISO set to ISO 125 which is the expanded ISO, base ISO being 200. It’s very difficult for you to see the image quality in this other than perhaps the colour rendition.

The next image shows the central part of the frame zoomed to 100% magnification.

This is an exceptionally sharp lens and camera combination and I would put it on a par with the Olympus EM5 paired with the Panasonic 14-45mm lens (which is excellent). What I have noticed though is that the lens starts to soften in the corners as can be seen in the next shot.

This softening isn’t too bad but you can also see some light fall off. I was finding that when shooting something near to me I was needing to stop down to about f/6.3 in order to bring the corner sharpness up to a level where I could add additional sharpening later. Being fair to the 12-32mm lens, it is an excellent performer and is never going to compare with the likes of the Olympus 25mm or 45mm primes. If you are shooting more distant subjects or those that don’t demand exceptional corner sharpness, it is ideal.

What is also noticeable about the images above is he colour rendition in the GM1. I have found the images on a par with the Olympus EM1. The RAW files are a pleasure to work with and I seem to be able to achieve great results.

Now one area I don’t usually like is shooting at higher ISO. If I have to push my camera to anything over ISO 400 I start to fret that I am losing image quality. So occasions where I have to shoot handheld in low light are something that I hate. Take a look at the following image where I had to shoot at ISO800.

Now take a look at a section of the unprocessed image at 100% magnification.

I have applied a very small amount of noise reduction to the image but it’s hardly noticeable. The low light performance appears to be on a par with or even slightly better than my Olympus EM5, something that surprised me as Panasonic have always produced images that are noisier than their Olympus competition. I would certainly have no problems printing this image at A2.

One odd thing that I noticed about the camera when shooting in low light was that it performed better with the 12-32mm lens than any of my primes. Neither the lens nor the body have any form of image stabiliser but I could consistently shoot clearer images. Use the 25mm and the shake would be very evident. I can’t explain that one.

In summary, put a good lens on this camera and it really performs in terms of image quality. And if you only have the 12-32 lens, it’s still a good performer if you are not ultra fussy about corner sharpness or know how to overcome this. It really is a superb quality pocket camera.


As someone has kindly pointed out since I made this post, the 12-32 lens is stabilised, so that sorts out my confusion. I even have to admit to having looked at the front of the lens to see if I could see OIS and I completely missed it. Time for new glasses I think.

    Thanks for doing this. I’m a fellow ultralight landscape photographer / hiker and I wanted to let you know your articles and research have been very helpful to me and indeed instrumental in my own decision making processes, having recently switched from Canon full frame to Micro four thirds. I currently use the Olympus OM-D E-M5 with the Panasonic 7-14mm and Olympus 40-150, and your articles have been very helpful and inspiring. I’ve been thrilled with and impressed by all of them! This is a tiny niche, but one with a ton of potential to improve the way we do photography.

      Thanks Justin,
      It’s always great to hear from a like minded photographer. It’s also great to hear that what I do has been useful to others. It makes the effort worth while. I hope you continue to stop by the blog.

    Great images! I’m not that lightweight as I use a DX but I think it doesn’t matter the camera as much as the photographer. 🙂

      Thanks. I’m pleased you like my work. Your right the equipment doesn’t matter so long as it doesn’t get in your way.
