Hi nice to have found this forum, found out a lot of hot news and discussions on the NEX system here! Just wanted to ask and verify this. I have a 5N myself which I bought a few months ago. My friend has a C3 which he bought it last year not sure when. And recently he just switched to the Samsung NX system and so I bought his C3 as my secondary camera. But found out some differences between the two SEL1855 kit lens. Not a big difference but the zoom grip on my lens looks more dense (spatial frequency) and his looks a little more sparse. And looks like the silver on the C3 SEL1855 kit lens is a little shinier than 5N's. Have any of you noticed this difference? Is it due to different periods of production? Or are there actually different versions of the SEL1855 similar to the difference between a regular SEL1855 and NEX-7's black SEL1855? Are there any differences in terms of optical performance? IQ? between them? Thanks!
