How much do you use the Omega? I was thinking of replacing my Bronica kit with the Omega. Just bought it and waiting for it to be shipped, although the back needs repair. I'm afraid I'm going to miss waist level finding. I use waist level and prism about 50/50 % each. And how do you find the speed of the lenses? I'm getting the 58 mm, 90 and 180. Think I will be using the 58 and 90 mostly. So Im a bit afraid of the 58 mm not being fast enough for handhelding because there is not alot of light here in Norway...
