What kind of lens corrections are we talking about here? I shoot with all Hassy H primes and have never had any gripes. The lenses I use are all superb (35,50,80, 100, 120, and 210) and my 100 is as sharp as it gets. I have the zoom but prefer the primes and rarely use my 120. Only flaw I see is that I get some ever so slight barrel distortion with the wide angles in some cases, but that is easily quickly fixed in Photoshop if necessary. I tried the teleconverter but sent it back and bought the 100 instead, as felt the TC added some slight softness.
Does the tilt shift adaptor introduce distortion, say with the 50-100 lenses? Thanks, Eleanor
No, the only way to take advantage of the digital corrections is to use an H3D/H2/CF combo. I believe that is true with the EXIF data as well.
