“There seems to be no real image quality issues with using the Speed Booster and for low-light work – a real treat. With DX lenses and the 0.71x magnification of the Speed Booster, you have a lot more wide options for the Olympus system.”
P.S.: A Lens Turbo version should arrive by end of this year. Save this search on Slidoo to get notified when it’s available on eBay.
