I'm not sure Paul, but since it a studio recording done at appr. the same time, I guess it the same aperture - F 13 or perhaps F11.
Next time I shall: 1. Make sure the conditions are very close to being exactly the same. 2. Use new 120 film (Kodak Ektar 100 or Fuji Astia 100) 3. Use a pro-lab for developing 4. Unfortunalely I don't have a por scanner, but I will use my Epson Perfection 3200 Photo, which does deliver reasonably good scans. I may compare the F4 165 mm LS lens to a reasonably sharp 50mm lens for the K-7. I must say I am surprised how sharp the 2.8 28-70mm zoom lens is. It actually beat quite a few primes :-) Jens -- Treat others as you would like to be treated yourself.
