Prime slr lens on a crown graphic??!

[Benjaminxon]

Is it possible?

I've grown weary of the dreary digital age but I've got a couple very nice prime nikon lenses an im wondering (after googling high and low) if there exists or is even Possible a a lens board/adapter that allows for me to utilize my prime lenses on my grown graphic?

Any answers would be wonderful, especially if it includes a, 'yes! And heres a link'

Thank you very much for any information.

I think it highly unlikely.

The flange focal distance on Nikon F-mount lenses is 46.5mm, which puts the lensboard awfully close to the film plane.

Then there's the angle of view and the image circle diameter. The lenses would certainly not cover 4x5 or even close.

Does the Crown have a focal plane shutter (I think not)? Nikon SLR lenses do not have shutters.

There isn't an adapter with a shutter built in where you could just plug a slr lens onto it? Enabling the prime lens to be utilized on a large format.

Are you thinking of using a 50mm Nikkor from your 35mm Nikon? These lenses cover 1x1.5 inches and will not cover 4x5 inches.

Benjamin,

You need to review my previous response, then do some research to understand the terminology.

You clearly do not understand basic lens functionality and specifications.
Understanding those subjects is critical to selecting lenses for LF work.

Understanding basic camera funtions, all you need is apature, light, and a light sensitive surface. With that in mind, what is stopping a large format camera being fitted with, for example a Nikon 24mm f/2.8 AF-D? A shutter is needed, which could go between the lense and the bellows. Really the flange focal distance doesnt matter if the adapter is build correctly to allow it. Realistically, the biggest issue i could think of is the weight of the larger lenses. Possibly an unfortable set up, especially with a hand held crown graphic. If the adapter doesnt exist then so be it but mathimatically it's viable. Am i wrong? Am I thinking too far out of the box?

Benjamin,

Yes, you certainly are wrong.

You are so far out in left field that it's impossible to continue the conversation.

As I said previously, you know absolutely nothing about what is required to use a lens on an LF camera,
and since you're not willing to learn, I shan't waste any more time on the subject.

What implies me not willing to learn? I'm now looking for more, other than 'It won't work.' What would it produce? Why couldn't you make it happen? Best case scenario things would be blurry?

The flange focal distance on Nikon F-mount lenses is 46.5mm, which puts the lensboard awfully close to the film plane.

Awfully close? Why couldn't the adapter allow the lens to sit farther away?

Then there's the angle of view and the image circle diameter. The lenses would certainly not cover 4x5 or even close.

In my head it makes sense, but without sitting down to do the math I can't point out the specifics. Found this while refusing to learn :-p
http://www.largeformatphotography.info/why.html:
The equivalent of a 24mm in 35mm is a 75/90 lens in 4x5, a 120mm lens in 5x7. Depth of field is a serious problem. The cameras movements become *necessary* to put everything in focus, and even though some subjects cannot be focussed entirely. Start thinking f32 where you thought f5.6 !
What would happen if you were to open the lens entirely and appropriate the correct distance to make it all work. How much of the 5x4 would you lose to a 24mm 2.8 lens mounted to the front?

Does the Crown have a focal plane shutter (I think not)? Nikon SLR lenses do not have shutters.

We covered the fact that there could be a shutter sitting right behind the lens. built into the adapter.

Why don't you come and visit me in left field. It's warm and cozy..

Here's another one by the OP. He disregards the significance of flange focal distance, focal length, coverage, shutter, and aperture actuation, also disregards the info. he has already recieved, saying "why can't it work".

There are many extremely knowledgeable members here who will bend over backwards to answer questions posed by newcomers who are willing to learn. When someone disregards the help and information they are recieving, refusing to do anything to inform themselves, frustration sets in.
