Recently my nikon eyepiece just kinda fell apart. I was ready to order a new one when I decided it might be advantageous to look into another brand because I've never really liked the fit of the nikon against my eye. Now I'm also thinking slight magnification might be nice. I shoot with a nikon d300s. Any one have experience with magnified cups? Is it worthwhile focus wise? I looked at the Nikon DK-21M for magnification and the hoodman eyecup for comfort
