Can a lens cause a metering issue? Nikon FE SLR inconsistencies
I have two Nikon FE's with two Nikon lenses. I was curious how their metering worked so I did a test.
- Nikon FE A - Set for ISO400, No EC, has fresh Energizer batteries measuring about 1.55-1.58 volts each.
- Nikon FE B - Set for ISO400, No EC, has mix of old/used generic batteries measuring about 1.50-1.52 volts each.
- Nikon 50mm f/1.8
- Nikon 35mm f/2.0
- Sekonic L308S meter - Set for ISO400 and 1/60th second
- Panasonic DMC-LX3 - set for ISO400, No EC, Shutter priority 1/60 second
I am standing inside my bedroom and facing the other side of a narrow hall way to drywall frame to the left of the hallway bathroom. To the right is the bathroom which is dark inside, the door is open. It's 4PM in the afternoon and there's a window to the left high, and the sun is shining in.
- Nikon FE A
- 50mm lens - 1/60 is between f/5.8 and f/8
- 35mm lens - 1/60 is exactly f/2.0
- Nikon FE B
- 50mm lens - 1/60 is f/8
- 35 mm lens - 1/60 cannot be achieved. f/22 gives 1/1000th reading.
- Sekonic light meter
- Facing wall incident: f/2.0
- Facing wall reflective: f/5.6
- Facing lens incident: f/2.8
- Facing lens reflective: f/5.6
- Panasonic LX3
- At 1/60th, it reads f/5.6
I assume f/5.6 at 1/60 is the correct metering. How come the 35mm lens gives such bad readings? I also noticed that when I put the 35mm on Nikon FE B, it is really tight. Once it's on, the aperture ring is really tough to turn. The 50mm on Nikon FE B is fine. Both lenses are fine on Nikon FE A. Is this a metering issue or something is wrong with the mechanical coupling of the lens to the body?
Any help would be appreciated.
