Leon here. Yes, that's my current theory since they do look quite thick and dense (got no idea however how they should look). I should add that everything else looks fine on it (the bulbs are 2x300 watt, not 2x150 watt as I quoted above). However even when I use the correct mixing box for a 5x4 neg the printing time is still in the order of minutes. Re the lenses, this is using them at the largest stop since if I stop down the printing time becomes too much to bear.
