Thanks everyone for chiming in. I've checked some older negatives and they're scanning well - levels are nice and even from the shadows across to the highlights. I'm using three lenses with the MV: Pentax M 35mm F2.8, Pentax M 50mm F2 and Pentax A 135mm F2.8. The negatives from my recent B&W films look
very dark from all three lenses, which leads me to think it's either the camera or the development from the lab. I've had consistent developing from them for a while now, so I'm less inclined to think the fault is with them.
I'm using Tri-X and my ASA dial is set to box speed (400). All quite strange as I've not changed any settings on the camera, yet the recent negs are really dark.
