I use a 58mm standard straight hood on mine. It's 24mm deep, and has a 62mm opening. Never had a bit of trouble with vignetting. Bought it cheap on ebay, and it came with a cap, so I don't have to remove the hood to cap the lens, unless I'm putting on the top half of the ERC. The W-60 is 80mm wide, and does interfere a bit with the rangefinder window (just checked). An S-60 (the rubber model), though it looks really cool on the 14E, completely blocks the rangefinder window, and would through off the meter too. In general, SLR hoods are not designed to work properly on fixed lens rangefinder cameras.
