how would i make a cambo compatible with an ilex 127mm f4.5 or a tele megor 400, as they use different lens boards (i think)?
if i went with the cambo i would need this for older lenses: http://www.calumetphoto.co.uk/eng/product/cambo_flat_lensboard_drilled_for_copal_3/386-652a. . . .
. . . Nearly all of us think very hard before buying pur first press, technical, or view camera. Nearly all of us learn what we really want/need by using that first camera and replace it within a year. Whatever decision you make, except not to get one at all, will probably be wrong. Go ahead, but keep that in mind.
If the filter is inside the bellows then you don't need multicoating.
That is like saying that the only coated element you need in a lens is the front one. Coatings on all surfaces in a lens have an effect on flare, contrast, etc.
Well of course all surfaces have some effect... but not an equal effect. There is no element behind a rear-mounted filter. Also, light impinging on a rear-mounted filter will do so perpendicular ot its axis- the light is well collimated due to the aperture. The largest effects are very clearly that from the front element. Go ahead and pay astronomical prices for large multicoated front filters if you don't believe me.
Hood on the front, filter on the back, money in the pocket.
But you are also assuming people are shooting very stopped down.
No I'm not. Surely you don't think there is as much solid angle of stray light at the rear of the lens as there is on the front element? That is why hoods and compendium shades are so effective.
P.S. Rear filters also don't vignette.
I have a grand total of four 67mm filters and two conversion rings for all my lenses that I use them on. It didn't bother me to pay the extra money. For that I get a lot of convenience.
