I have been working on a book which discusses how to improve your photography and which takes a different approach to the more usual “instruction manual” format. On reviewing the draft my Editor helpfully commented that perhaps I should drag myself out of my Landscape comfort zone and sample some of my own medicine. So this week’s image is in response to his suggestion.
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.
As regular readers will know, I recently splashed out on the purchase of a Panasonic GM1 camera. If you are not familiar with the GM1, it is possibly the smallest Micro 43 system camera that you can buy. My thinking was that I would use it as a backup to my main Olympus EM5, a lightweight travel camera, possibly pairing it with my GX1 infrared or as a replacement for my LX7 compact camera. The LX7 is a lovely camera and I really enjoy using it but there are times when I want better quality and a higher pixel count than its 10Mpixel sensor will give me. If the GM1 is a nice pocket camera it might replace the LX7.
So, I have been using the GM1 for a couple of weeks now and am starting to get a feel for how its specification translates into real life shooting. I know quite a few of you are keen for me to share my experience (as you keep writing to me) so here we go. First off, let’s compare the size of the GM1 to the LX7 which is a compact camera and which fits quite nicely into my pocket.
The GM1 that I purchased came with a 12-32mm f/3.5 – 5.6 lens. The neat thing about this lens is that is collapses down when not in use. This makes the lens and camera together roughly the same depth as the LX7 which also has a lens that retracts. Here you can see the two cameras side by side from above with UV filters in place. Notice the depth of the GM1 body (which is on the left) is less than the LX7 although the lens is deeper.
When viewed from the front you can see the GM1 is actually smaller than the LX7 both in terms of width and height.
This is even clearer to see when the camera is viewed from the rear (GM1 is on the left). Despite this reduction in size the screen area is the same size as the LX7. I know this as I fitted a screen protector from the LX7 to the GM1.
Once both cameras have their lenses extended for use they are still roughly the same size.
One aspect of the GM1 that some users may find annoying is that there is no hotshoe to fix an external viewfinder to so you are limited to the screen display. Personally I haven’t found this an issue and the screen has been easy to see even in quite bright conditions.
What I really like about the GM1 is that ability to attach other high quality Micro 43 lenses to the body. Here you can see the Olympus 45mm prime in place.
And also the Olympus 17mm Pancake lens.
With the pancake lens in place the camera is a very small package that fits easily into your pocket.
But size isn’t everything, even with small cameras. You need to know how the camera handles. So far I have tried the GM1 with the 12-32mm kit lens, Olympus 9-18mm wide angle, the primes you see above, the Olympus 25mm and Olympus 60mm macro lens. The 60mm macro lens is actually quite large and is possibly where the camera starts to feel unbalanced but is still perfectly usable. Using the camera with the 12-32 is very enjoyable and is probably the ideal partner for it.
In conclusion, this camera is a good substitute for my LX7 in terms of size although the 12-32 lens (equivalent to 24-64mm) is less flexible than the LX7 which has a 24-90mm equivalent lens.
In my next post I will look at the quality of the GM1 in comparison to the LX7.
I would like to publish a note of thanks to the security officers at Canary Wharf in London. Yesterday I visited London with a couple of friends as tourists to take pictures. One of our locations was Docklands with the intention of photographing some of the icon architecture including Canary Wharf.
Waiting for our friend outside the Tube Station we were taking some pictures of the buildings when we were approached by a security officer to ask if we had permission. What was nice about this is that the officer took the trouble to look at the pictures we were shooting and then contacted security to allow us to continue. It’s great when officials recognise that not everyone with a camera is a terrorist or pervert and treat people with respect.
