This is about the same 75-300mm lens that you have seen and loved before with just a few fine-tuned adjustments. Starting from the top, the focus ring will remain the same. There is now a printed zoom range, effectively getting rid of the 35mm equiv. notice. The zoom ring will be the same, according to Olympus, even though it appears a bit different in photographs,and it will be available only in black with a new ZERO-Coating added. This coating is said to improve ghosting and flare throughout its range.
