p.1 #1 · p.1 #1 · Rx100 flare spot / hot spot problem


I'm seeking help from those who have the 24-70mm equivalent lens versions of the Rx100, ie MIII, MIV, MV. Does this lens have a similar flare/hot spot as does the 28-100mm lens on the MI and MII?

I have the Rx100MII and although find it to be a fine camera for most purposes the flare/hot spot with this lens is becoming troublesome with the types of pictures I'm using it for more recently, ie snap shots of buildings/architecture. In these types of images where you tend to point the camera towards the sky the excessive background brightness, especially on overcast days, causes a blue/purple flare/hot spot which is mostly visible in dark areas in the centre of the image. If the centre of the image is bright then the hot spot doesn't appear. See several example below, where in some cases the shadows become blue/purple in the centre of the image.

Something odd going on here; I have the Mk I and have had it since it came out eons ago and have never seen this effect....must update that camera! Though I so rarely use it...

I shoot with a7R11 converted to .715nm and another with .830 conversion. Try the radial brush in Lightroom to reduce the hotspot. I returned a 24-70GM, 2.8 because of this problem. Good luck.

How is this relevant to the OP's query?

1. This is a completely different system involving a different camera and a different lens.
2. It is visible light (OP's RX100 II) vs near IR.

My comment is only about the 24-70 lens. Yes, on a different system but hot spots on one body very often occur on a different body with the same lens. Thanks for your question.

Just an FYI, OP was not talking about the 24-70GM. He is talking about the built in lens on the rx100 series camera. This camera is not an Interchangeable Lens Camera.
