Bronica lenses converted to pentax 645??

Khaledgawdat · 09-24-2011, 11:32 AM

I have a ton of bronica 645 lenses and I thought it is not possible to use them on pentax 645
I have seen this lens on eBay and it is described as a bronica lens converted to pentax 645 mount?

Any body knows how was this done?

Here is my guess:

The flange was removed and replaced with a Pentax flange and shimmed to the correct distance. The shutter was disabled to remain open. Most likely fully manual F stop operation like most other 3rd party lenses.
