If you did not have enough yet, you can always go back to the manufacturing of a Canon 500mm tele-lens (in a much older video) or you can make a virtual tour of a Canon lens manufacturing plant.

Here is very good news for the Sony customers. But it’s even better when we read the list of names that Sony immediately provided: Lens manufacturers having already expressed their interest in designing lenses for the E-mount:

• Zeiss, traditional ally of Sony around the A-mount of Alpha SLR cameras.
• Tamron, old friend of the orange house, and partner back in the Minolta times.
• Cosina, owner of the very elitist Voigtländer brand.
• Sigma, manufacturer of the broadest range of compatible lenses.

Assuredly, this type of talks is usually very discreet. Here, Sony decided to strike our imaginations in one big marketing blow, demonstrating their clear intent to develop the NEX range of hybrid mirror-less cameras in the best conditions for a long life. The message has been received loud and clear.

Manual focus lenses for the Pentax K mount manufactured and sold by Cosina under the Carl Zeiss and Voigtländer brands are coming to an end: Cosina announced it ceased manufacturing them.
