So, I'm new to LF and I just got my Intrepid 4x5 and an assortment of lenses including my main lens - Nikon 90mm. Went backpacking. Processed the film and found that everything shot with that lens came out horribly wrong. I guess it needs to be serviced or replaced. Ever seen anything like this? I made a couple exposures with my Rodenstock 150 and that came out beautifully. Any idea what could be wrong?
EIther your Nikon 90 mm is not a wide angle lens,or you are missing an element. I suspect it is not a WA. Does the ID on the lens indicat WA?
Here are a couple pics. Could this not actually be a wide angle lens? Could it have simply been that the lens was loose on the lens board? I sure appreciate your response.
I should add that in the field I discovered the rear element and lensboard were loose, but I thought I took care of it (without tools)
What is your lensboard made out of?
No, not really. Sorry.Originally Posted by brianentz
OTOH, you got your first lesson in LF -- the ground glass does not lie. It took me a lot longer than my first trip to fully, viscerally, understand that. Once I latched hold of that concept I wasted a whole lot less film, and my "winners" became a much higher percentage of my shots.
You done good. Stuff like this is how we learn.

Which filter did you put on it? I ask because there's not too bad image in the corners.
A picture of the lens on its board would be helpful. Side views, so we can read the ID etc. on the front of the barrel.
On the various pictures that came out with the same defects I used a couple different filters. Orange and a polarizer separately.
Did it look like that on the ground glass?
No, but the perimeter of the image on the ground glass was dimmer as I don't have a fresnel lens - yet.
