<p>I have a 110 f/2.0 FE Planar on the way.<br>
My other Zeiss/Hasselblad lenses are Bay 60 and I've been merrily using Bay 60>67mm adapter and threaded 67mm filters.<br>
Also a 67mm Lee 75 filter adapter and the smaller Lee 75RF filters (75 x 90mm)</p>
<p>My question is (probably a quite common theme but my searches came up blank) - what my options are with the Bay 70 filter size for the 110mm lens?</p>
<p>There is a Bay 70 to Bay 60 Hasselblad-made step-down adapter (Part No. 3040775) but that would still mean Bay 60>67mm adapter, then 67mm filters (or adapter ring), which I suspect is going to cause mechanical vignetting but I was hoping for any feedback from anyone who'd tried?</p>
<p>There is, I think, a Bay 70 to 77mm adapter? That's not ideal, I'd love to avoid 77mm filters and the Lee 75 range only goes up to a 72mm adapter ring. </p>
<p>My primary use case is going to be yellow/yellow-orange threaded filters for B+W, alongside some landscape with the Lee CPL/GND options.</p>
<p>A Bay 70 to 67mm adapter would be ideal, assuming it won't cause vignetting, but I can't find such a thing.<br>
Otherwise I guess I will just have to experiment with placing a 67mm filter a little way out from the front element to see if it looks like worth pursuing the B70>B60>67mm>67mm filter option. Or, more probably, just bite the bullet on B70 to 77mm adapter and a couple of 77mm filters.</p>
<p>Thanks.<br>
