This follows on some issues that came up on an earlier post of mine "Help on Lens Choice" where the issue of sharpness in 8ftx10ft enlargements was being discussed. I wish to exhibit enlargements. I am planning on acquiring a 4x5 for a project so that, theoretically, the enlargements will be better than from my Contax 645. But then that is what I think. But is this true? If I photograph the same scene on the Conatx 645 (vacuum back, and the super 120 Makro) and on a 4x5 (Planning on the Toyo CF) with a good lens, and make enlargements the same size, how will the results compare? Since I plan on doing landscapes primarily, will the 4x5 make an impact (compared to the 645)? Thus the 'movement' advantage is minimal? What got me worried is this answer from a gent at Mamiya on the Mac User Forum. The question is: "Will I see a noticeable improvement in image quality with a 5x4 over 66 or 67 format" Response from: Paul D'Ambrosio - 11:13am Jul 16, 2001 EST (1.) Mamiya America Corporation "Quentin, You should not really notice a difference between an image shot with a 6x7cm camera as opposed to an image shot with a 4x5" camera. We have seen images taken with a 6.4x5 cameras that have been enlarged to 5'x4' and they look extremely sharp. The main benefits are the movements. (swings, tilts ect) that you get with a 4x5 view camera. Every photographer has his/her idea of what camera would be best for him or her. Fortunately we have many models for you to choose from. I suggest that you visit our site at www.toyoview.com. There you will find all the specs and information that you need to help you make the right choice for yourself."
