Had my part almost not ordered because one lt. Of various reviews the camera strap does not get into his pocket !? So with the 16-50 lens I have absolutely no problem to get the strap in the bag - yes, you have to fold it 2x - but that is dearer to me than him cram somewhere ...
The front compartment is sufficient for two wonderful lens cleaner, a SD card, a cleaning cloth, a spare battery and a filter (in large protective packaging) ....
