do I need to drop the bed when using 75mm on Toyo 45Aii?greenspun.com : LUSENET : Large format photography : One Thread
I own a Toyo 45Aii, a schneider APO symmar 120 & 210mm, just want to get a wider lens like 75mm. But I am not sure if this lens will be in the way, cause me to drop the bed to avoid it?
If so, I may consider the new Super symmar 80mm, just don't know how long do I have to wait, anyone know that?
Thank you very much. Chin.

Chin: It is necessary to drop the bed or raise the lens with a lens of 90mm, so I am sure you will have to with the shorter lenses. With a monorail, you can just move everything to the front of the rail. It really isn't a problem. Just drop the bed, raise the lens back to center an tilt the lens back to verticle. It takes longer to tell it than to do it.

Oh No! you do not need to drop the bed of a Toyo 45 AII and a 90mm! Actually, it is even possible to use some fall in portrait orientation. But YES droping the bed is not a problem at all and should'nt be a concern to inhibit you to get a 75mm lens or wider.

I have used the Toyo AII with both a 75mm and 90mm lens without ever having to drop the bed to avoid vignetting. About the only time I've felt a need to drop the bed is when using the longer LEE ND Filters.

I second (or third or fourth) that no drop is needed for a 90mm, but I don't have a 75mm. My bigger concern with a 75mm would be bellows movement. The bellows balks big time with the 90mm when I try to get a lot of rise.
I wish Toyo had put levels on the standards. When I do drop or rise the bed and want the standards vertical, I'm just guessing. I might have to add some someday.

I have used a Toyo AX with both 90 and 75mm for a few years now. I have never had to use drop bed with the 90, even when using front fall and tilt. The 75 may require drop bed, especially in a vertical composition, but not all of the time.

I'm using a Toyo 45AX and a Nikon 75mm. I've never had to drop the bed in either horizontal or vertical positions, even with my Lee filters in place.
