So,
I just read this threat and I just got a 135mm macro for my 67 II and am very disappointed with the fact that it has a bad ratio to it. At work (dentistry) I use a Canon 10D with a 100mm macro with a ring light and I can get down to 3 teeth in photographing without any other help. Why couldn't they do this with the 67. Can you shoot small flower with the extension tubes. I understand that the larger the film size the harder it is to get 1:1 since 1:1 on 35mm is much smaller a area than a 1:1 on 4x5.

The RB67 can get 2:1 with the 90mm standard lens w/o extension tubes - the bellows focusing extends 40mm+ and the floating lens elements found in the 50mm thru 140mm macro lenses allow good flat field focusing. The wider lenses will get very close, beyond 1:1 mag. ratio.

I'll admit: 35mm macro photography is easier but for prints greater than 5x7 inches 6x7 format is better; although, you can go closer with 35mm, especially if you use micro lenses which can give you 1:20 magnification ratio.

View cameras are great for doing macro work but movements offer no advantage with such shallow DOF.
