Still waiting for the Samsung Galaxy K Zoom - the newest smartphone camera with a 20MP sensor - I can't wait with sharing a few of the first results I got from the Nokia Lumia 1520 and Sony Xperia Z2. It's interesting to note that 20MP seems to have become the new "standard" for high-end smartphone cameras by the way.
I'll tell you a bit about my method of comparing. First I (usually accidently) find a scene I think worth looking at. I take several shots of that with the smartphones I'm testing, making sure the light is as constant as possible. Nowadays, when it's very sunny outside, I usually choose the corresponding white balance on all devices.
After that I copy all the results to my PC, I check them in detail and pick what I believe is the very best from each device. Then I resize them - usually to 640 x 360 pixels, to fit this page. Next I either make crops in the same size, or I zoom in to 100% (using Picasa) and make a screenshot (like I've been doing in this case).
Finally, I start writing the post like I'm doing now, adding the shots and details as I go along. And doing so it's in fact the first time I actually compare the results from the devices I'm testing myself. It has become a simple method I find not only easy but also fair, and it's a way of surprising myself during the whole process as well :-)
With the Lumia 1520 and Xperia Z2 I made a few shots in bright and not-so-bright light - in this post you won't find the "low light shots" a lot of you seem to appreciate so much (will work on those later). First, a scene from an antique store, captured pushing both devices directly on the window to avoid reflection.
The Nokia Lumia 1520 was set to 5MP/16MP (in 16:9 aspect ratio), I need to make two shots with the Sony Xperia Z2 - one in Superior Auto (8MP) and one in manual (15.5MP in 16:9). Where the Lumia 1520 will be more or less identical, we might see some small differences between both shots from the Xperia Z2.
In all comparisons, you'll see the Lumia 1520 first, Xperia Z2 second. First you'll see resized versions of the smaller results.
