Re: New Olympus Patent: 400mm f4.0 MFT Lens

Hello all,

If this new Olympus zoom comes to the market is it likely to be internally focusing like the Pro 40-150 f2.8 ? I personally would feel this is Very important.

Shooting wildlife in wet or dusty conditions I have never been happy with lens barrels that zoom in and out.
Many Thanks,
