This is the first part of a few battles between two 20MP sensors - those of the Nokia Lumia 1520 and the Sony Xperia Z1 Compact. Sony boasts it's offering a very good mobile camera and does so with a lot of technical brouhaha if I may say so.
The Sony Xperia Z1 Compact - and I quote - redefines the premium smartphone market by placing the best Sony technologies from the flagship Xperia Z1: Sony’s leading camera technologies “G Lens”, “Exmor RS for mobile” and “BIONZ for mobile”; a 4.3 inch TRILUMINOS™ HD display and X-Reality™ for mobile; premium dust-resistant and waterproof (IP55/IP58) design.
Well: it's waterproof, that's for sure and I think it's amazing that the mobile industry is allowing Sony to have this USP for this long (yes, I know Samsung announced the same for the S5 at the Mobile World Congress). The HD display of the Z1 Compact is certainly better than even the FullHD screen of its predecessor in terms of visibility - black is much deeper black on the Z1 Compact. But its no competition for Nokia's FullDH ClearBlack, IPS LCD display.
Now how do the sensors compare? That's what this battle is about. In this post you will see (only) two shots from both, shot in 4:3 to get the maximum out of the sensors. Both shots were taken inside, in more or less good lighting conditions. As you know, you only need to push the button once to get two shots from the Lumia 1520: one in high-res (hence 19MP) and one in PueView (5MP).
With the Sony Xperia Z1 Compact, you'll have to go to manual settings and choose 20MP for the first shot (the sensor is 20.7MP to be exact), and then choose 8MP for another shot in 4:3.
Like I wrote in an earlier post, you can't choose 4:3 in the "Auto Superior" setting on the Xperia Z1 Compact, since that will only allow you to shoot in 16:9. You'll have to wait for the Xperia Z2 to do so, but that will be a few months from now I guess.
I don't know if the camera software on the Z1 Compact will be updated to do the same by the way, and in fact I'm not completely sure if the Z1 compact uses oversampling when it makes the manual 4:3 shots in 8MP (I guess so, what else would it do?)
In this post, first you'll see the resized shots coming from the 5MP and 8MP results from both smartphone cameras. Next, you'll see screenshots I made at 100% from those same shots. Last, you'll see two crops from each shot I took at the highest resolution. So even with only two shots from each device, this will be a pretty long post I'm afraid - but quite revealing.
You know the drill, you'll find all the original shots on OneDrive. In all comparisons, you'll see the Lumia 1520 first. Here we go.
The first scene was captured inside a sports hall. The light was okay, not very bright, not too dark either. Average, I'd say, but certainly bright enough. Here are the resized results (from the oversamped shots - 5MP and 8MP).
