single coated lenses and filter question

Will a single coated lens, such as the 80mm hasselblad chrome

lens on a 500c transition model benifit in terms of flare reduction

from a multi coated filter ? I have a bay 50 to thread adaptor for

this camera and am able to utilize filters from my old canon F1.

However it dawned on me today that these filters are quite

old now and newer filters which are multi coated might be of

benifit to my old lenses. Is this the case or a waste of money?

Also, what brands do you recomend and which vender ? If a filter

is coated will it say so on the filter ring? Thanks to all.

A filter can only add to the flare. The advantage of a multi-coated filter would be that it adds less flare to the overall total.

 

By all means use multi-coated filters if you frequently shoot into the light but otherwise a good deep lens hood will be much more beneficial.

I'd agree that you'll probably see more consistent improvement in contrast with a proper lens hood. This seems to work on nearly any old, single coated lens, regardless of format.

The problem with flare only happened when shooting into a field

and into the sun. I do use the standard lens shade. Perhaps a

larger lens shade or my hand may reduce flare. From what you

are telling me, a top quality multi-coated filter could improve or

reduce as opposed to a single coated but not remove it. I do

know that removing the filter for the shot is better but, I like to use

N.D. and grduated filters so in this case I supose using good

muti coated could help. Anyway what do you recomend for

manufacturers and venders ?

I agree that adding any filter can never reduce flare, but the advantages of multicoating a filter are the same as a lens, although perhaps the internal reflection problem is not as relevant. You do get a bit more light transmission.

 

Some manufacturers tell you how much more light transmission there is with multicoating, and it is usually only a few percent (eg 93% versus 97% or something). Is it worth it? You do pay a lot for the extra few percent.

 

That said, I like multicoated filters as a rule, but I have some that are single coated and, in the absence of any test, there does not seem to be too any difference on film.

 

To your other questions, I expect that all m/c filters will say so, as this will justify the price increase.

 

IMO, there probably isn't that much optical difference between filter brands, as long as they are comparable (eg Hoya has 4 ranges, I think). Others may disagree!

 

There are many threads archived on filters for H/blad. See the post directly above yours for more on non-T* lenses!

The loss of transmittance caused by a single-coated (or uncoated) filter usually doesn't matter much. What you really want to avoid is to stack uncoated filters (or filters that are single-coated for the same color).

 

The loss of transmittance does matter when you put a whole lens together, with a dozen glad-air surfaces (or more). My new multi-coated Nikkor 50/1.8D has about the same transmittance as my mid-60s single-coated 50/1.4.

I obviously meant glass-air surfaces in my previous post, sorry...

Conrad, I shoot similarly and try to mask as much of the sun out of the image

as possible by flexing my Lindahl bellows shade around and checking the

groundglass for vignetting

 

good luck
