Wide Center Filter for 65 & 75mm lens

[nhp]

First of all, thanks for many advice to last posting. Well, I want to know about wide center filter. If I use 65mm or 75mm lens, should I always use center filter? As far as I know, center filter required when camera movement is pretty big or large. Is this true? I am going to get Rodenstock 65mm or 75mm lens for 4X5 camera, but still wondering which one is more useful for architecture and interior shoot. Also, when I use 6X7 roll film back on my Horeseman LX 4X5, which lens is useful? Should I use center filter when I use 6X7 roll film back,too? If you have any advice for this, please tell me about it. Thanks again. www.welcome.to/studionaki

Well, I have not yet used a centre filter on my Fuji 65mm (with 4x5

film), and I have not noticed a "hot-spot" problem, which would

necessitate the use of a filter. I do use a centre filter on the Fuji

G617 with slide film, but remove it when using orange or red filters

with black and white film. Again, difficult to see a material

difference.

A center filter is definitely needed on my Nikon SW 65mm for 4x5, but

not so with the 6x9 back (unless extreme rise is used).

The answer is really to shoot some of your usual film and see. You

may not want to buy such a filter yet.

With chromes you might see some light falloff towards the edges. This

also depends on how much lens movement you're using and what the

subject matter is.

With your rollfilm back, divide the lens focal length by two to get an

APPROXIMATE of the 35mm equivalent. e.g., a 105mm is like a 50mm

standard lens on 6x7. With 6x9, use a factor of about about 2.5.

For architectural use, may I suggest a 55mm Rodenstock Grandagon with

your 6x7 back? (Personally, I prefer a 6x9 back with 58mm and 65mm

lenses as most frequently used ones).

 

You'll probably have less use for a centre filter when you use your LF

with a rollfilm back. But that again depends on how much movements,

e.g., lens rise, you will use.

I haven't seen a need for use of a CWF with the Rodenstock 65mm f/4.5 Grandagon that I use and 96% of what I shoot in large format is transparency film. I

use a Horseman 6x9 back and find that the 65mm is more useful than a 75mm will be. With interiors it is often easier to crop than to move the camera

backwards.

I use Rodenstock's 75/4.5 Grandagon a lot both in 4x5 and with a 6x9 roll back often with extreme movements and I've yet to see the need for a centre filter. However I'm only shooting in b/w, if you use transparency film there may be a need for one.

Good luck, Trevor.

In my opinion it's often best to use the longest lens you can use

while shooting interiors. I believe you'll get more utility out of

the 75mm rather than the 65mm. I've been shooting both interiors and

exteriors with the Schneider 72XL. It's truely a unique and

outstanding lens for architecture. You might consider it as another

choice. I also use a CF with the 72XL when using significant

movements. When I used a 75mm lens, I often shot a single scene with

and without the CF. Again, if I was working close to the edge of the

image circle, a CF made a noticable difference.

If you can tolerate the 1 1/2 stop loss in speed, a center filter

gives additional detail in the corners. Because more light gets to

the corners of the film, more detail is recorded.

So even if you lighten the corners in PhotoShop or when printing, you

can't bring out the detail if it isn't there on the negative. A

center filter will make your shot crisp to the corners.
