Standard? Really? (120/36)*50 = 167. (180/120)*36 = 75. Check your arithmetic before posting and remember that the long side of the 4x5 gate is 120 mm. (210/120)*50 = 87.5. That's more than twice normal (43 mm) for 35 mm still. More than a rch long, I think.210 is your standard 4x5 lens. They are just a hair long. 180mm on 4x5 is equivalent to a 50mm lens on a small format camera when comparing horizontal angle of view.
If you use a pseudonym for a screen name and use a real name in your tag line you must expect a little confusion about who you are.
