G'day Michael here from Australia down under. I have made the difficult decision to sell all of my Pentax DSLR system and make the changeover to Sony's NEX E-mount system. In May this year, I bought my partner a Sony NEX 5n with 16mm, 18-55mm and 55-210mm lenses for her Mother's day present. I was so impressed with the way that camera performed and the output of the image quality was very comparable to my Pentax K-5 images. The lightweight NEX system and persuasive video advertisements has won me over so I have actually ordered the new NEX 6 with 16-50 PZ lens. My partner and I are looking forward to sharing our lenses with our respective bodies and starting the new journey of NEX imaging. I have a question regarding the 16-50mm PZ. Am I able to zoom manually with this lens or is it strictly motorized? Thanks in advance. michael.
