Linhof 617 SIII 72mm XL - Looking to see what shade to use

[dean_makkos]

I have alinhof 617S III w/ 72mm XL and would like to know if anyone has any ideas on what shade I can use. Beeing that it is on a 617 the angle of view is over 100 degrees and the diameter w/CF is 110mm.

If anyone has any ideas, please let me know.

Dean, unfortunately, it's almost impossible to find a lenshade for a

72mm wide angle lens that really is effective and won't vignette.

Since you cannot check the groundglass, just shade the lens with a

wide brimmed hat, or the equivalent, and hope for the best.

There is no lenshade for either the 90 or the 72mm that will not

vignette and that would provide protection.

Dean,

The same question came to me last year and I made myself a prototype

hood for my 90mm lens. It looks awful, but works fine. With cardboard

I cut four panels shapped so to have angled sides and glued them to

black cloth. A piece of Velcro ties both ends. This foldable piece

can be mounted around a Lee holder or anything that fits the lens and

shows square sides.

The advantages of this clumsy solution come from not using the filter

thread, leaving room for my bulky Schneided CF,no vignetting and

still permit some sort of see-through viewing. It's also quite easy

to carry around. Although not so fun to use, but my lens/camera kit

suffers from horrible flare and I can't even think not using some

kind of hood.

Of course, if Lee, Lindhal or anybody else would design some clever

solution I'd rather prefer to use theirs...

If this description comes to be uncomprehensible, I could try to draw

and send it to you by e-mail. Or to anyone who thinks it's worth the

trouble.

Good luck.

On a 4x5 camera or a 617 Technorama?

It is very difficult, if not impossible to make an effective hood for a

2.25 x 6.75" format like the T617 with the 90 or the 72 that won't

vignette. And the asker has the 72.

Bob,

I made it for the Linhof 617, with 90/5.6 lens, but I suppose it

could also be done for any lens. Panels would be more angled, maybe

shorter, but the main concept should work anyway.

Considering that most of the light cone inside the camera is quite

useless, any shade on top and botton side will be rather welcome.

Even a grotesque project like mine.

I really appreciate the feedback. Question, Hasselblad x-pan made a

shade for the 30mm which is almost 100 degree angle of view. I know

this is a diffrent system, but the angle of view is almost the same.

Fuji made it for the 90mm 617 systm which has an angle of vie of 90

degrees, why is it Linhof, as reputable as they are, has not made

shades for there lenses on this system? I just find this hard to

believe. If anyone comes up with a solution I would greatly

appreciate it.

Thanks again for all your help.

"why is it Linhof, as reputable as they are, has not made shades

They certainly do. They sell Heliopan hoods for both the 180 and

250mm lenses for the 617 as well as for the 135mm for the 612.

However there is no way to make an effective hood that will work

without vignetting on the 72 and 90mm lenses. ESPECIALLY

WITH THE CENTER FILTER.

Even with the older 617 using a CF on the 90SA and a step-up

ring (very thin brass) and a convertible Heliopan rubber hood in

the wide angle position vignetting could not be eliminated. And a

lens this wide, was not effectvely hooded with a rubber hood

anyway.

"and a step-up ring (very thin brass) and a convertible Heliopan

Sorry left out the size. It was the 105mm Heliopan convertible

rubber lenshood.

I just find it impracticle to shoot a 617 with my Nikkor 90mm sw @4.5 into the sun direction with out flaring.I carry a shovel in my car that I have used for a lenser in a few cases.I usually use a tall tree over hang or a canyon wall shadow.Improvise would be my suggestion and avoid back lit subjects or use a c-stand and a 18"x24"
