Hello and greetings from Canada,

I have a D700 with a Nikon 17-35mm f/2.8, 24-70mm f/2.8 and the 70-200 VRII and i wish to take the plunge into landscape photography using Lee NG filters and all.

The thing is, i'm trying to find a decent prime wide angle lens but from all the tests i've seen so far they all fail miserably as far as vignetting on a FF body and i'm a bit worried about that (even Zeiss).  And that's not even considering any filters :-(  Am i just splitting hairs?

I know i have the 17-35 and 24-70 which would probably work great for landscape (and i'd save money) but thanks to Nikon there's no more markers and i don't know how to use the hyperfocal anymore without them.

Tried DOFMaster but they ask the distance to the subject, why would they if i use hyperfocal?

Any thoughts?

Thanks a million.

Respectfully,

Ronald

I'm not a Nikon guy, but I have two quick answers.
1) Vignetting is usually not a problem.  Landscapes are usually shot with the aperture stopped down some, which makes vignetting all but disappear.  And any that remains is easily correctable in post processing.
2) My DoF tool asks for the focal distance because it is used for the DoF calculation.  It also reports the hyperfocal distance which is always the same regardless of focal distance.  This is as it should be.

Thanks for your reply,

You are right i was looking at it the wrong way, indeed at F166 or F22 all vignetting should be gone unless the filter set-up is all wrong.  That's one thing settled :-)

However what i meant in the DoF software is that it's asking for the "Subject" distance...  When i use to do this manually pre-digital i never had to bother with the subject, for example i knew that on a 35mm lens set at F16 or F22 everything between let's say 10 feet and infinity would be sharp without ever knowing where the subject would end up (great for photojournalism), that is because lenses back then has the markings on the barrel, and even a $2K 24mm from Nikon doesn't have that.

I'll contact the makers of DoFMaster about that i guess.

Thanks again.

When everybody thinks the same... nobody thinks.

Why? Simply enter any distance, and then look for the hyperfocal in the results.
