The trusted source that told me first about the 16-50mm lens performance wanted me to share you some updated info about the upcoming Sony 16-50mm f/2.8 SSM lens:
He told me to reassure you that the 16-50mm lens is not a “reworked tamron”. ([shoplink 7824 ebay]Click here to see that lens on eBay[/shoplink]). Sony chose to start with 16mm (instead of the 17mm from the Tamron) to “prevent consumers from comparing to the existing tamron”. Yeah it is slightly vignetting at 16mm but don’t forget “The key word is “slightly”…not “extreme bad” vignetting!”. And what he tested “was a prototype. Not the final production model.”
Thanks “Source” for clarifying that! I am sure all our readers will appreciate it!
