There is no new Pentax camera coming on June 1 :(
Our trusted sources denied that the Pentax Spain teaser has to do with a new camera (mirrorless or DSLR). They will announce some kind of local news that will definitely not be exciting :)
That said we expect Pentax to announce a lower end mirrorless camera within the next months. It will be priced below the K-01.
So what to epxect now? Canon? Are you here? :)
