Is this adapter for the Helios 103?
Also, is there a Helios 84 in your photo??

This adapter will not fit Helios 103. This adapter is for lenses with external bayonet like pictured Helios-94. If you need adapter for Helios-103, we have it for focusing helicoids (not for MFT mount) - http://www.rafcamera.com/en/adapter-contax-to-m52x1.
