Recessed lens holder for Fuji Fujinon SWD 75mm f5.6

[norm123]

Hi all
I'm looking to get a 75mm lens for my Sinar F1. I am mainly interested by landscape.

My question is <<How deep should be my recessed lens holder to get comfortable and able to tilt/swing easily? What is the minimum should I consider?>>

Regards

I was wondering the same thing since I've gota 75 on the way.

To an extent it sort of depends on the camera requirements.

A couple weeks ago I had my Fujinon 65mm lens out, it is in a recess of 11mm, it is difficult (ish) to get things moved with my clumsy fingers. A friend turned up after I was home, the fiddling came under discussion. He pulled out his Linhof recessed board with his 65mm Nikon lens, it has a 6mm recess and is a fair bit easier to use; given me some food for thought.

I use my 65mm on my Shen Hao HZXII with bag bellows (can use standard bellows, just) but with bag bellows things are easy peasy. Also use it on my Toyo 45G mono rail where the recessed boad is very handy. Although technically not required for the Toyo, the compresson of the bellows is a bit disconcerting unless using the recessed board.

I know you are talking about a 75mm lens so maybe fit it with a flat board, focus on infinity, then move the front standard forward 6mm then 11mm, this will tell you how much you are compressing your bellows, or in other words, how close to crushing them you may be and this is what the compression will be with a recessed board with 6mm or 11mm depth depth when you extend the front standard.

This is what my friend had, although it looked a lot worse than this one.

I mounted my 75 on a flat board and see why a recessed board is needed to get the bellows extended a bit more. I might get away with this, but its at the very beginning of the rails very near the GG focused at infinity.

I'll give it a try this way and see how it works out for what I am doing.

My next lens will probably be a 150mm. Working my way up the line one at a time.
hint... im shopping

Several considerations here. First, does your camera's bellows crimp considerably with a flat board and/or does the standard spacing prevent using a flat board? If not, you may as well just get a flat board. A 75mm lens won't cover much more than 4x5 anyway; movements will be minimal if possible at all (my Fujinon 75mm f/5.6 barely covers 4x5). Second, how large of a circumference does the recess of a Sinar recessed board have? If it is generous and you find you need a recessed board, then get as deep as practical; it'll keep the bellows from crimping. By "generous" I mean does it give enough space for you to comfortable manipulate the controls? This is different depending on lens and operator. I have my 90mm and 75mm lenses mounted in deep recessed Technika boards. I have to set aperture with the end of the cable release and can barely get fingers in to set shutter speed and cock the shutter. However, I'm fairly adept at doing those things and it's not a bother for me. Using deep boards gets me movements with my 90mm lens that I couldn't get otherwise on my folding Wista DX without crimping the bellows. However, the 75mm can't move much due to the coverage limitations; the recessed board is pretty much overkill except it makes things easier setting up as I can keep the standards farther apart and don't have to worry about getting the camera bed in the image area.

Best,
