Hi - I have been given a 65mm f6.8 Angulon lens, serial no 10807xx. It came with on a MPP lens board with a hole of 25mm diameter that I assume is a 000 fitting. It is in a Synchro-Compur shutter (speeds 1sec to 1/500th sec). The shutter needs a good CLA as it only works correctly 1 in three times of using.

Before I get the shutter CLA'd I would like to know if the lens will cover 5x4, if not what will it cover and is it worth the cost of the CLA.

Thanks in advance
