Image Distortion

[belodion]

Observe the distortion caused by the 1020's shutter. I had it set to 1/1600s, and the train would have been travelling no faster than about 50mph/80kph. I have noticed such distortion on a number of occasions, and assume that other 1020 owners will have done so?

That's an issue with OIS not the shutter. I have it too. Wobbling the phone fixes the distortion.

Thanks for your reply but I don't understand. This only occurs with fast-moving subjects. You mean I've got to wobble the phone just before I shoot, or during the exposure?

Hmm. Well that's different for me. I have the same effect sometimes in portraits or selfies. A slight wobble and the next photo is better.

But if I remember correctly, using manual focus disables OIS. Maybe try that?

It's not the OIS. Indeed it's the shutter itself. Lumia 1020 uses rolling shutter, that's why there are distortions during capturing fast moving objects. Frankly, You can't do much about it

The shutter indeed. I tried blue1k's suggestion of manual focus a few days ago with same subject, but it made no difference. This is the sort of distortion clearly visible in action shots taken with early focal-plane shutters, and I can only assume made more pronounced by the positioning of the 1020's shutter. Why blue1k encounters the effect with static subjects I can't think.

To clear up the OIS and MF rumour, OIS is enabled during MF, however it is not enabled until the shutter button is pressed (try it yourself, set to 4s shutter and point up, look at lens, press shutter button and then rock phone, see your lens move?).

This is simply distortion at high speed caused by the shutters shape. The way to cure this is to use Photoshops Lens Correction Filter or similar and "un-distort" the image by straightening the image. This will result in a very small portion of the image being cropped but will make a world of difference.
