Lee Filter Holder on 90mm

[steven_s._miric]

I am getting in to Lee filter holder system for large and medium format. My question is if I have to get "wide angle" adapter ring for 90mm large format lens, because of vignetting or I can go with regular 82mm ring ( I have Fujinon 90mm/5.6 ). Thanks.

I've used a Lee system with an LF Grandagon-N 90mm (67mm front)

without using a wide-angle adapter ring without any problems, but I

used it on the Lee "wide angle kit" (see below). I've used the

regular Lee system (foundation kit + shade) on an Fuji 65mm for GX680

with 95mm "standard" adapter and I had some slightly darkened corners

(just about to vignette). More important than which adapter ring you

pick, IMO, is the type of Lee kit you pick. The regular foundation

kit with the shade that slides in the front slot is longer than the

Lee "wide-angle" system with the clamp ring made permanently onto the

back of the shade with 2 filter holders. The difference is about

1.5cm, in terms of the position of the front of the shade when

compressed to it's minium. The "wide angle" adpater ring will buy

you about .5cm in shortening of the overall system. Of course, this

might be the critical amount you need. If you get both the WA

adapter ring and the wide-angle kit you almost certainly will be

vignette-free. Sorry I couldn't answer specifically.

I use a Schneider SA-90mm 5.6 with the Lee wide angle adapter, and

haven't had any issues through the full range of movement. I'm not

sure if a standard adapter would also work. As the previous poster

suggested, if your ever going to stack other things on the front

(e.g. Lee lens shade or more filters), the wide angle adapter gives

you more margin.

You will most likely want the wide-angle ring.

The Lee regular rings are quite thick. They might not vignette in

neutral position, but will almost certainly cut your image circle for

all but your long lenses. I found the regular rings cut so much of the

image circles of my Apo-Sironar-S 150/5.6 and Apo-Symmar 210/5.6

that I never use them (5x7 format). On the other hand, I had little

problems with the wide-angle rings even on 90/8 and 110/5.6.

I used the regular Lee system (before they came out with the various

wide angle stuff) and a 90 mm F 5.6 Super Angulon. I got vignetting

several times, mainly with movements. I'd avoid using a 90 mm lens

with the regular Lee adapter.
