"PB-4 or PB-6 Bellows???"


East Haven, US
          

What is the difference between the PB-4 Bellows and the PB-6 Bellows? I do know that there is a huge difference in price but other that that does anyone know why I would be better served using the PB-4 over the PB-6 on my F-100?

The major difference between the two bellows is that the PB-4 allows swing and shift of the front standard. This works somewhat like the tilt and shift lenses, and its main purpose is to allow you to adjust the plane of focus when you are dealing with very limited depth of field at high magnification. I have the PB-4 and to be honest, I think the advantages over the PB-6 are minimal. I would not recommend spending the extra money.

Thanks Tad, I was going to purchase the PB-6 with a PK-13 tube. As far as the lens....... Well I am really considering the 105mm micro. I like the added distance. Do you know if this sort of set up will still allow the camera to meter?

What magnification are you trying to get? With a 105 micro on a fully extended PB-6, you are only looking at a 2:1 reproduction ratio. The PK-13 will help some but not much. If you need more magnification, I'd recommend going to a shorter focal length lens like the 60mm micro or a 24mm wide angle. The following link will give you some very useful tables with magnification ranges and working distances for various lenses with the PB-6:

Scroll down to the files "p19.gif" and "p20.gif" to see the tables.

I believe your F-100 will meter just fine with this setup.
