Rokkor 40 lens shade
I recently acquired a Rokkor 40 from another member here on RFF, but it came without a shade/hood. I've gotten into the habit of almost always using a shade, so my first question is: Is a shade as necessary as I'm making it? Am I just compulsive about this?
Regarding the Rokkor:
I've looked around for an original rubber shade, but they are few and far between.
I had a couple of ideas for a shade and I'm wondering whether they might work.
1. Use a step-down ring from 40.5 to 39 and utilize my Summaron shade. Would stepping down to 39 impact the field of view of the lens?
2. Use a step-up ring and buy another shade to fit that ring?
3. Use a series of stacked step-up rings to make a shade of my own? Would a "ridged" shade be a problem as opposed to a "smooth" shade?
It seems as if whatever I do, I'm going to have to get the shade away from the aperture ring enough to fit my fingers in there. That's a reason I'm not sure about just finding a plain old aftermarket 40.5 shade.
