Leica Q and Dirt inside

If anyone want evidence that dust can get onto the sensor in a Q, here you can find samples at dpreview, and below is one clear example with dust(s) visible in the frame.

Whether or not the dusts were already in the camera before shipped out and eventually found their way onto the sensor, or sneaked into the camera later, is unclear.

The Leica Q3 is available for pre-order at B&H Photo Video and Adorama

Can’t speak for a Q, but the Q2 is IP-52 rated.

The 5 is the dust part:

Dust protected

Ingress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the safe operation of the equipment.

 

Thats all Leica promises….  

I am curious what other cameras people own that have an IP rating 😉

Les saletés dont il est question semblent être essentiellement des taches sur le capteur qui, effectivement seraient une plaie sur un boîtier fermé comme le Q.

J'ai possédé un Sony NEX7 et un Nikon Z7 qui récoltaient beaucoup de saletés sur leurs capteurs alors que je changeais très rarement d'objectifs (uniquement des zooms Sony ou Nikon). Donc de longues séquences de nettoyage des photos dans DxO PhotoLab suivaient chaque reportage !

Après recherches sur différents forums j'ai appris que la raison tenait principalement à 2 causes : d'abord l'utilisation de zooms qui constituent mécaniquement des pompes aspirantes pour toutes sortes de poussières, et ensuite que ces fameuses poussières étaient surtout constituées de pollens qui sont des particules très "collantes" et que l'on rencontre désormais en toutes saisons !

Comme les Leica Q n'ont pas de zoom et qu'ils sont "scellés" pour l'utilisateur, je pense que le danger d'avaler des poussières est moindre. Mais l'indice IP52 évoqué par Leica pour le Q3 signifie que l'objet est simplement protégé "contre la pénétration des poussières" et "contre les gouttes d'eau tombant verticalement" ce qui ne correspond donc pas à une étanchéité absolue, loin de là...

À noter que les meilleurs smartphones sont IP67 (protection totale contre les poussières et les immersions temporaires)

En Anglais, s’il vous plait. Merci. 
 

 

The dirt in question seems to be mainly stains on the sensor which would indeed be a sore on a closed box like the Q.

I've owned a Sony NEX7 and a Nikon Z7 that collected a lot of dirt on their sensors while I very rarely changed lenses (only Sony or Nikon zooms). So long sequences of photo cleaning in DxO PhotoLab followed each report!

After research on various forums I learned that the reason was mainly due to 2 causes: first the use of zoom lenses which mechanically constitute suction pumps for all kinds of dust, and then that these famous dusts were mainly made up of pollen which are very “sticky” particles that we now encounter in all seasons!

As the Leica Q does not have a zoom and is "sealed" for the user, I think the danger of swallowing dust is less. But the IP52 index mentioned by Leica for the Q3 means that the object is simply protected "against the penetration of dust" and "against drops of water falling vertically" which therefore does not correspond to absolute waterproofness, far from there...

Note that the best smartphones are IP67 (total protection against dust and temporary immersion)
