Marker position changes with zoom levels on leaflet map with custom tiles

Ah pretty weird @orkut murat yılmaz eh!
It would be great (much better) if you could also add some screenshot that make more sense clear your use case
(i.e. that show your maker at zoom 5 and how then it looks, and where, at zoom:12, etc).

Just going kind of blind,
and according to this solution (https://stackoverflow.com/questions/17875438/leafletjs-markers-move-on-zoom)
you might try to set dimensions of the Leaflet Icon
(@see the attached screenshot)

Sorry for very late reply, it is solved with setting the dimensions of the custom icons.

Thanks for everything:)
